[ Bugzilla 1001607 ] 2012-10-04 Ilija Kocho * tests/kcache2.c: Include CYGHWR_MEMORY_LAYOUT_H in order to effectively test memory size. Bug reported and fix suggested by Bernd Edlinger. [Bugzilla 1001650] 2012-05-27 Ilija Kocho * tests/kcache2.c: Allow comilation for targets with less then 128KiB RAM by conditionally reducing of MAXSIZE to (1<<16) 2012-03-19 Sergei Gavrikov Jonathan Larmour * tests/except1.cxx (cause_exception): Fix compiler warning about variable that is set but not used.

Issue reported by Grant Edwards. * cdl/kernel.cdl: Reference the kernel instrumentation documentation. 2010-01-27 John Dallaway * include/instrmnt.h: Add instrumentation macros for event flags and the bitmap scheduler. * include/instrument_desc.h: Regenerate. * src/sync/flag.cxx, src/sched/bitmap.cxx: Add instrumentation. * cdl/instrument.cdl: Add CYGDBG_KERNEL_INSTRUMENT_FLAG and CYGDBG_KERNEL_INSTRUMENT_BITMAP options. 2009-10-04 John Dallaway * cdl/instrument.cdl: Add CYGDBG_KERNEL_INSTRUMENT_MLQ option. Issue reported by Pieter-Jan Busschaert. 2009-08-24 John Dallaway * doc/kernel.sgml: Use "reinterpret_cast" throughout the C++ thread entry point example. [ Bugzilla 1000550 ] 2009-05-14 John Dallaway * src/common/thread.cxx: Use the Cyg_Scheduler::get_current_thread() convenience function when instrumenting thread events. Bug reported by Pieter-Jan Busschaert. 2008-12-18 Jonathan Larmour * tests/tm_basic.cxx (STACK_SIZE): Revert accidental change of stack size back to CYGNUM_HAL_STACK_SIZE_MINIMUM. Changed by accident at same time as change below of 2006-12-08. 2008-11-18 Sergei Gavrikov * tests/tm_basic.cxx (max): Actually the meaning was right before, it was just the name that was wrong. So revert below, and change name to min. 2008-11-14 Jonathan Larmour * tests/tm_basic.cxx (max): Was wrong way round. Resolves issue 1000636. 2008-07-24 Jonathan Larmour * include/thread.inl: Silence some warnings by assigning string literals to const char *, not char *. 2007-08-23 Hans Rosenfeld * tests/intr0.cxx, tests/kintr0.c: As suggested by Bart Veer, priorities of the interrupts created by intr0 and kintr0 can now be overridden by the HAL through HAL_INTR_TEST_PRIO_x constants. 2007-07-02 Gary Thomas * src/debug/dbg_gdb.cxx: * src/common/thread.cxx (Cyg_IdleThread): Add (char *) casts to make GCC/4.2.x happy. 2007-06-11 Nick Garnett * tests/klock.c (entry0, entry1): Modify mbox part of test to reflect use of plain mbox implementation. The precise ordering of events is slightly different. 2007-01-07 Andrew Lunn * src/sync/mbox.cxx (Cyg_Mbox::get): Fix compiler warning with gcc version 4.1.2. 2006-12-08 Nick Garnett * src/sched/mlqueue.cxx (add_thread, yield): * src/sched/sched.cxx (unlock_inner, thread_entry): * include/mlqueue.hxx (class Cyg_SchedThread_Implementation): * include/kapidata.h (CYG_SCHEDTHREAD_TIMESLICE_MEMBER): * include/bitmap.hxx (class Cyg_SchedThread_Implementation): Reimplement timeslicing code. There is now a timeslice_count field in each thread which is moved to and from the per-CPU counter during thread dispatch. This approach has been taken to minimize the changes needed to SMP code. Scheduler specific thread functions handle counter save, restore and reset. These functions are defined (as empty inlines) even when timeslicing is disabled, or in non-timeslicing schedulers, to avoid adding ifdefs to the code (this change actually removes some). * tests/timeslice2.c: * cdl/kernel.cdl: Added timeslice2 test to test behaviour of timeslicing while being preempted. 2006-10-12 Nick Garnett * cdl/synch.cdl: Added CYGIMP_MBOX_USE_MBOXT_PLAIN option. This is tested in various places but was not actually defined. It now is and defaults to 1 so that the plain version of mail boxes is selected. * include/mboxt.inl: * include/mboxt2.inl: Moved various CYG_ASSERTCLASS() calls to be within scheduler locked regions. Race conditions could have caused them to fail before. * tests/mbox1.cxx: * tests/kmbox1.cxx: Updated tests to work with mboxt implementation. This requires thread 1 to run at lower priority than thread 0. 2006-08-21 Jonathan Larmour * doc/kernel.sgml: Use reinterpret_cast, not static cast Thanks to Tony Garland for the report in bug 1000299. 2006-05-19 Andrew Lunn * host/instr/dump_instr.c: Use CYG_NELEM from infra. * src/instrmnt/meminst.cxx: Use CYG_NELEM from infra. 2006-05-09 Andrew Lunn * tests/stress_threads.c: Add string.h to avoid compiler warning. 2006-04-11 Sergei Organov * doc/kernel.sgml: Fix typo 2006-04-10 Sergei Organov Implement FIFO variant of scheduling of DSRs and make it the default. This is reworked patch originally suggested by Stefan Sommerfeld . * cdl/interrupts.cdl (CYGIMP_KERNEL_INTERRUPTS_DSRS_LIST): make it cdl_component. * cdl/interrupts.cdl (CYGSEM_KERNEL_INTERRUPTS_DSRS_LIST_FIFO): new option for CYGIMP_KERNEL_INTERRUPTS_DSRS_LIST. * include/intr.hxx (class Cyg_Interrupt): new static variable dsr_list_tail. * src/intr/intr.cxx (call_pending_DSRs_inner): add CYGSEM_KERNEL_INTERRUPTS_DSRS_LIST_FIFO variant. (post_dsr): likewise. * tests/intr0.cxx: fix comments to match actual option names. * tests/kintr0.c: likewise. 2006-03-27 Marco Cruz * include/thread.hxx: removed extra qualifier of Cyg_Thread::reinitialize() to permit compile on gcc 4.1.0 * include/sched.hxx: removed extra qualifier of Cyg_Scheduler::thread_entry to permit compile on gcc 4.1.0 2006-02-14 Andrew Lunn * tests/timeslice.c (STACK_SIZE): Reduce the stack size so it will compile on targets wit h only small amounts of RAM. * tests/fptest.c: Calculate the size of ftp2_values array to fit the amount of RAM in small systems. * tests/clocktruth.cxx: Fix the header. 2006-01-19 Nick Garnett * src/sched/sched.cxx (thread_entry): Fixed a bug which could cause a thread to be started with a non-zero scheduler lock. The previous code only decremented it by 1 so if the previous thread was executing with the lock > 1 the thread ended up with a non-zero lock. This is fixed by decrementing the lock in a loop until it reaches zero. * src/common/thread.cxx (idle_thread_main): Added an assert for a non-zero scheduler lock. 2006-01-10 Nick Garnett * src/sched/sched.cxx: * include/sched.hxx (class Cyg_Scheduler): Added thread_entry() member function. This handles thread startup housekeeping. Zeroing the scheduler lock is handled by calling unlock() so that DSRs may be run. * src/common/thread.cxx (thread_entry): Refactored code to call Cyg_Scheduler::thread_entry() instead of doing all the work here. 2005-11-23 Sergei Organov * doc/kernel.sgml: Fix description of CYG_ISR_CALL_DSR and CYG_ISR_HANDLED. Fix example isr_function() accordingly. 2005-10-23 Andrew Lunn * include/flag.hxx: We need thread.inl for the empty() function implementation which the compiler wants to inline. 2005-08-03 Andrew Lunn * tests/ksem1.c: Type fix to fix a compiler warning. * tests/mutex3.cxx: new cannot be both static and global. * tests/testaux.hxx: Ditto 2005-07-30 Andrew Lunn * src/sync/mbox.cxx (tryget,peak_item): initialize local variable to avoid compiler warning. 2005-06-21 Peter Korsgaard * tests/kcache2.c (test_dcache_operation): Fixed compiler warnings about formats strings for diag_printf. 2005-03-27 Andrew Lunn * tests/tm_basic.cxx (_run_all_tests): Fixed compiler warning. 2004-12-15 Sergei Organov * cdl/scheduler.cdl: Correct the description of CYGIMP_KERNEL_SCHED_SORTED_QUEUES 2004-09-24 Nick Garnett * src/sched/mlqueue.cxx (enqueue): Fix bug in sorted queue insertion: priority test was inverted. Spotted by TomChen. 2004-08-08 Bart Veer * cdl/counters.cdl: add new option for the clock interrupt priority. * src/common/clock.cxx (Cyg_RealTimeClock): use this option. 2004-04-15 Jonathan Larmour * tests/fptest.c (do_test): Silence aliasing warning when breaking doubles into two ints. 2004-04-11 Andrew Lunn * doc/kernel.sgml: Expanded the documentation about the use of CYG_FLAG_WAITMODE_CLR. 2004-03-27 Sebastien Couret * src/debug/dbg-thread-demux.c (dbg_thread_syscall_rmt): Only needed if CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT is enabled. 2004-03-12 Jonathan Larmour * include/kapi.h: Add throw specifications throughout. * src/kapi.cxx: Ditto. * include/sched.inl: Move include of thread.inl further down to allow Cyg_Scheduler inlines to be defined first. * include/thread.inl: Reorder destructors section and include sched.inl right before it to solve mutual header dependency problems. 2004-03-04 Jonathan Larmour * doc/kernel.sgml: Document cyg_thread_delete return value. 2004-02-19 Jonathan Larmour * tests/kmutex3.c (cyg_start): Use CYG_TEST_NA. * tests/kmutex4.c (cyg_start): Ditto. * tests/mutex2.cxx (cyg_start): Ditto. * tests/mutex3.cxx (cyg_start): Ditto. * tests/sync3.cxx (cyg_start): Ditto. * tests/thread2.cxx (cyg_start): Ditto. * tests/fptest.c (cyg_start): Use one line NA msg. * tests/smp.cxx (cyg_start): Ditto. * tests/timeslice.c (cyg_start): Ditto. * tests/tm_basic.cxx (cyg_start): Ditto. 2003-12-08 Dan Jakubiec * src/common/kapi.cxx: Added new function cyg_thread_get_id(). This function returns the unique thread ID for a given thread handle. * include/kapi.h: Added function prototype for cyg_thread_get_id(). * doc/kernel.sgml: Added documentation for cyg_thread_get_id(). 2003-10-13 Nick Garnett * src/common/clock.cxx (Cyg_Counter::tick): Changed code to deal with manipulation of unsorted lists (see ChangeLogs passim). There are several corner cases where the current code does not work. Replaced with a more straightforward, but slightly more expensive, implementation. 2003-09-22 Reinhard Jessich * src/common/clock.cxx: Removed label/goto add_alarm_unlock_return to get rid of compiler error when CYGIMP_KERNEL_COUNTERS_SORT_LIST is enabled. 2003-09-01 Bart Veer * doc/kernel.sgml: fix typo, cyg_thread vs. cyg_thread_t 2003-07-18 Nick Garnett * cdl/counters.cdl: Removed the counters override CDL options. These are no longer very useful, since too much non-kernel code now uses the HAL options to get these values. 2003-07-10 Nick Garnett * src/common/clock.cxx (Cyg_Counter::tick): In unsorted list case: moved saving of next node details to before re-insertion of alarms with intervals. The call to add_alarm() can make enough of a difference to the list to need to force a rescan. 2003-07-06 Bart Veer * include/test/stackmon.h (cyg_test_size_a_stack): If stack checking is enabled, look for 0xdeadbeef rather than 0x0 to determine usage. Also reset the interrupt stack to that value. 2003-07-02 Jonathan Larmour * doc/kernel.sgml: Document that timeouts for timed functions are absolute, not relative. Also document new semantics for cyg_semaphore_timed_wait() for timeouts in the past. 2003-07-01 Nick Garnett * include/clock.hxx: Made Cyg_Counter::add_alarm() and Cyg_Counter::rem_alarm() private functions. They no longer lock the scheduler, so should not be called directly, only via the Cyg_Alarm functions. * include/clock.inl: Removed inline version of Cyg_Alarm::disable(). It's no longer a one-liner and is thus better as a proper function. * src/common/clock.cxx (Cyg_Counter::tick): Rewrote the unsorted list option. If the function of one alarm adds or removes other alarms, then is was possible for the list to become corrupted. The new implementation attempts to avoid this problem. (Cyg_Alarm::initialize): Added scheduler locking to protect the enabled flag. (Cyg_Alarm::enable): Ditto. (Cyg_Alarm::disable): Ditto. Moved here from clock.inl. (Cyg_Alarm::add_alarm): Removed scheduler locking, it is now always called from functions that have already locked it. Added an assertion to double-check this. (Cyg_Alarm::rem_alarm): Ditto. * cdl/kernel.cdl: * tests/kalarm0.c: Added new test to test that alarms can be added and removed in alarm functions safely. 2003-06-25 Thomas Binder * src/common/clock.cxx (Cyg_Counter::rem_alarm): Bugfix: call Cyg_Scheduler::lock() before calculation of index into alarm_list array to avoid race condition with multi list counters. 2003-06-06 David Brennan 2003-06-23 Nick Garnett * cdl/kernel.cdl: Added tests/bin_sem3 to list of kernel tests. * include/sema.hxx: Added declaration for wait with timeout for Cyg_Binary_Semaphore. * include/instrmnt.h: Added instrumentation point for binary semaphore timeout. * src/sync/bin_sem.cxx: Added wait with time-out function to Cyg_Binary_Semaphore class. * src/sync/cnt_sem.cxx: Modified semantics slightly to claim an available semaphore even with a timeout in the past. This is in line with the new timed wait in bin_sem.cxx. * tests/bin_sem3.cxx: Created new test for timed wait binary semaphore. 2003-05-20 Andrew Lunn * src/common/kapi.cxx (cyg_thread_get_next): Passing a *current pointer as NULL if how you start the walk of the linked list. So don't assert on NULL. Reported by Daniel Lidsten. 2003-05-05 Gary Thomas * tests/tm_basic.cxx: Support new option controlling number of times this test runs. This is useful for long-term stress and performance analysis. 2003-05-03 Jonathan Larmour * include/mqueue.inl (Cyg_Mqueue::get): Fix invalid loop termination cheque for whether busy or not. (Cyg_Mqueue::put): Ditto. 2003-03-03 Jonathan Larmour * tests/fptest.c: Make all variables static to avoid any risk of collisions with symbols defined elsewhere in eCos. 2003-02-27 Jonathan Larmour * include/kapidata.h: Revert change of 2001-08-23 and instead make it conditional on the GCC version. Also add comments explaining why this file has been apparently obfuscated. 2003-02-25 Nick Garnett * tests/fptest.c (alarm_fn): Added CYG_TEST_PASS() call to keep configtool happy. 2003-02-24 Jonathan Larmour * cdl/kernel.cdl: Update doc links. * cdl/synch.cdl: Ditto. * cdl/thread.cdl: Ditto. 2003-02-19 Nick Garnett * tests/fptest.c: Changed to run for a constant time rather than a constant number of iterations, with a shorter run time for simulated targets. 2003-02-10 Gary Thomas * include/thread.inl: Add more debug info to thread stack checking. * tests/clocktruth.cxx: * tests/clockcnv.cxx: Use for diag_printf() prototype, rather than hard coding (because it was inconsistent). 2003-02-05 Gary Thomas * tests/kcache2.c (test_dcache_operation): New test to verify that the DATA cache syncs properly. 2003-01-31 Nick Garnett * cdl/kernel.cdl: * tests/fptest.c: Added this program to test interaction of FPU with multiple threads. 2003-01-30 Jonathan Larmour * src/common/thread.cxx: Fix potential warning and overflow with CYGNUM_KERNEL_THREADS_DATA_MAX == 32. 2003-01-28 Jonathan Larmour * src/common/kapi.cxx (cyg_thread_get_next): Be quite zealous about checking the validity of passed in threads in debug mode. (cyg_thread_get_info): Ditto. * cdl/thread.cdl: Correct max legal value for CYGNUM_KERNEL_THREADS_DATA_MAX. 2003-01-22 Jonathan Larmour * doc/kernel.sgml: Document cyg_thread_info type. 2003-01-13 Dmitriy Korovkin 2003-01-13 Jonathan Larmour * include/mqueue.hxx: Allow get/put to return time out. * include mqueue.inl: Ditto. 2003-01-02 Gary Thomas * tests/kcache2.c: New subtest for raw data cache operations. 2002-12-12 Nick Garnett * src/common/kapi.cxx: * include/kapi.h: Added function cyg_thread_get_next(), cyg_thread_find() and cyg_thread_get_info() to allow the current set of threads to be enumerated, and per-thread information to be retrieved safely. * doc/kernel.sgml: Documented new KAPI calls. * src/common/thread.cxx: Zero unique_id in thread destructor so that a stale thread pointer can be checked for validity. * include/instrmnt.h: Added cyg_instrument_state() to report the current state of an instrumentation flag. Moved ifdef for CYGDBG_KERNEL_INSTRUMENT_MSGS out of within FLAGS ifdef. We can have messages without flags. * src/instrmnt/meminst.cxx: Added cyg_instrument_state() to report the current state of an instrumentation flag. Modified cyg_instrument_msg() in line with header and table changes. * host/instr/dump_instr.c: * host/instr/instrument.sh: * include/instrument_desc.h: Added a final NULL element to the generated table in instrument_desc.h to mark its end. Otherwise code that does not have access to the table definition cannot find its end. Also added ifdefs to allow instrument_desc.h to be used to acquire the structure definition and table pointer. 2002-12-03 Gary Thomas * tests/tm_basic.cxx: Add tests of 'flag' synchronizers. 2002-10-28 Andrew Lunn * tests/tm_basic.cxx: Include infra/diag.h and removed the incorrect prototype for diag_printf 2002-10-16 Gary Thomas * include/test/stackmon.h (STACKMON_PRINTF): Use #include to get prototype for 'diag_printf()'. 2002-10-01 Jonathan Larmour * src/common/clock.cxx (add_alarm): Tweak last change to allow alarm order for identical alarms to be the same as it used to be. 2002-09-30 Jonathan Larmour * src/common/clock.cxx (add_alarm): Fix bug resulting in alarms not being added at all if a lower triggered alarm already exists. Reported by Christoph Csebits. Also fix bug when alarm is entered for the same time as tail. These bugs only apply for CYGIMP_KERNEL_COUNTERS_SORT_LIST enabled. * doc/kernel.sgml: document that order of callback for alarms at identical times is unspecified. 2002-08-08 Nick Garnett * src/sched/sched.cxx (unlock_inner): Removed initial assertion. This has served its purpose and with the introduction of routines such as unlock_reschedule() is prone to firing in otherwise benign circumstances. 2002-08-05 Bart Veer * cdl/kernel.cdl, include/kapidata.h, include/kapi.h: Allow configurations with the kernel but no malloc 2002-06-05 Gary Thomas * include/kapi.h: Fix prototype (to allow builds with net stack). 2002-05-24 Jesper Skov * cdl/kernel.cdl: Fix typo. 2002-05-23 Jonathan Larmour * include/kapi.h: Expose new cyg_thread_add_destructor and cyg_thread_rem_destructor APIs. * include/kapidata.h (struct Cyg_Destructor_Entry): Change CYG_ADDRWORD to more correct cyg_addrword_t. * include/thread.hxx (class Cyg_Thread): add_destructor and rem_destructor are onyl static when not per-thread. * include/thread.inl (add_destructor): Don't need to lock and unlock scheduler when destructors are per-thread. (rem_destructor): Ditto. * src/common/thread.cxx (exit): No need to lock scheduler when calling destructors. * doc/kernel.sgml: Document thread destructor API. 2002-05-23 Nick Garnett * doc/kernel.sgml: Some more edits to the kernel documentation: changed all references to message boxes to mail boxes, clarified some thing in various places, fixed a few typos. 2002-05-23 Jesper Skov * cdl/kernel.cdl: Cleaned up kernel tests rule. Also remove tests depending on the C API when its not present. And skip dhrystone test when debug or instrumentation is enabled. * tests/tm_basic.cxx: Fixed warning. 2002-05-22 Nick Garnett * doc/kernel.sgml: Fixed up SMP documentation. Rewrote condtion variable documentation to make its relationship to mutexes more apparent. 2002-05-22 Jesper Skov * tests/smp.cxx: Move inclusion of testaux.hxx to below NA checks. 2002-05-21 Bart Veer * doc/kernel.sgml: Major update to the kernel documentation. 2002-05-21 Jesper Skov * src/common/clock.cxx (dsr): Fix latency ifdef guards. * tests/tm_basic.cxx: Same. 2002-05-20 Jonathan Larmour * src/sched/mlqueue.cxx: Don't force timeslice tracing on by default against the user's wishes. * cdl/scheduler.cdl: Instead provide an option controlling it. 2002-05-09 Jonathan Larmour * include/kapidata.h (CYG_HARDWARETHREAD_MEMBERS): entry_point should be a pointer to function not an addrword (which may be different). (cyg_reason_t): Define cyg_reason_t as an enum not an int. (struct cyg_mutex_t): Define mutex protocol as an enum not a cyg_uint32. Define locked member as a cyg_atomic, not a cyg_bool. 2002-05-09 Nick Garnett * tests/timeslice.c: Modified test thread to accumulate run time by reading HAL clock, and to detect and record changes of CPU. The previous version of this code reported varying results - probably as a consequence of cache effects. * include/instrmnt.h: Fixed left-over debug edit to MLQ instrumentation enable code. 2002-04-29 Jesper Skov * include/kapi.h: Added cyg_alarm_get_times and cyg_counter_multi_tick. * src/common/kapi.cxx: Same. Er, fix oversight. * doc/kernel.sgml: Doc update. 2002-04-24 Yoshinori Sato * src/sync/flag.cxx: Don't set default args in func definitions. 2002-04-24 Jesper Skov * tests/dhrystone.c: Moved platform max number of passes to CDL in HALs. 2002-04-23 Jesper Skov * tests/dhrystone.c: Allow platform to define max number of passes via CYGPRI_KERNEL_TESTS_DHRYSTONE_PASSES. 2002-04-09 Jonathan Larmour * include/kapi.h: Use NORET attributes from cyg_type.h. * include/sched.hxx (class Cyg_Scheduler): Ditto. 2002-04-08 Nick Garnett * src/sync/mutex.cxx: Added IF_PROTOCOL_ACTIVE macro to condition use of the mutex counter. This means that a mutex that is not configured to participate in a priority inversion protocol does not count for operation of that protocol. 2002-03-04 Lars Viklund * include/kapidata.h (CYG_SCHEDTHREAD_ASR_MEMBER): asr_inhibit is cyg_ucount32 - must match 2002-02-13 Hugo Tyson * doc/kernel.sgml: NEW FILE: Correct reference to uITRON doc. 2002-01-28 Jesper Skov * tests/kexcept1.c: Fix warning. 2002-01-24 Jesper Skov * tests/kcache1.c (time0DI): Disable interrupts around the sync+invalidate process. * tests/kcache2.c: Same. 2002-01-23 Jonathan Larmour * src/intr/intr.cxx (mask_interrupt): Disable interrupts. (unmask_interrupt): Ditto. (mask_interrupt_intunsafe): New function to avoid disabled interrupts. (unmask_interrupt_intunsafe): Ditto. * include/intr.hxx (class Cyg_Interrupt): Declare above new funcs. * src/common/kapi.cxx (cyg_interrupt_unmask_intunsafe): Above replicated to KAPI. (cyg_interrupt_mask_intunsafe): Ditto. * include/kapi.h: Ditto. 2002-01-07 Nick Garnett * tests/except1.cxx: * tests/kexcept1.cxx: Added ifdef to disable these tests in ARM PID platform. This platform cannot generate any of the exceptions that this test needs to work. 2001-12-12 Jesper Skov * tests/kcache2.c (time_ilock): Put some dummy goto statements in to prevent compiler from moving labels around. 2001-11-29 Jonathan Larmour * src/sched/mlqueue.cxx (timeslice_cpu): Reset timeslice_count on a timeslice. Noticed by Tony Kho. 2001-11-23 Jonathan Larmour * tests/klock.c (entry1): Support running with CYGFUN_KERNEL_THREADS_TIMER disabled. 2001-10-30 Nick Garnett * tests/kcache2.c (test_dsync): Added call to HAL_ICACHE_INVALIDATE_ALL() just before DCACHE disable. In platforms where both caches are controlled together, such as the VR4300, not doing this can result in strange behaviour as the ICACHE gets turned off under the program's feet, when it is not ready for it. 2001-10-17 Jesper Skov * tests/dhrystone.c: CYGINT_ISO_STRING_STRFUNCS check changed to ifdef. 2001-10-12 Jonathan Larmour * cdl/synch.cdl (CYGIMP_KERNEL_SYNCH_MQUEUE_NOT_INLINE): New option to avoid inlining mqueue implementation. * src/sync/mqueue.cxx: New file to provide non-inline version of mqueue functions. * include/mqueue.hxx: Don't include .inl if user doesn't want inlining. * include/mqueue.inl: Allow choice of inlining or not to be overridden by macro. * tests/mqueue1.cxx: Never use inline version. 2001-10-11 Jesper Skov * tests/kmutex3.c (new_thread): Fixed allocation: increase counter before starting threads which have been allocated resources. * tests/kmutex4.c (new_thread): Same. * tests/mutex3.cxx (new_thread): Same. * tests/testaux.hxx (new_thread): Same. * tests/kcache2.c: Fixed warning. * tests/stress_threads.c: Same. 2001-09-20 Jonathan Larmour * host/instr/dump_instr.c (main): Fix argc check. 2001-09-07 Jonathan Larmour * include/thread.inl (measure_stack_usage): Deal with stack limits. 2001-09-07 Nick Garnett * src/common/thread.cxx (set_priority): Change argument to instrumentation call to new_priority rather than current priority. (Suggested by Andrew Lunn). 2001-09-05 Jesper Skov * include/mqueue.inl (Cyg_Mqueue): Initialize busy flag of last entry in the list. 2001-09-04 Jonathan Larmour * cdl/instrument.cdl (CYGDBG_KERNEL_INSTRUMENT_BUILD_HOST_DUMP): Remove redundant requires, and adjust make rule to be more portable across hosts. (CYGDBG_KERNEL_INSTRUMENT_MSGS_BUILD_HEADERFILE): Invoke script with sh directly rather than rely on executable attribute. * host/instr/readme.txt: Update build of host dump as per the changed CDL. * cdl/kernel.cdl: Don't build nullinst.cxx any more. Build meminst.cxx only in CYGPKG_KERNEL_INSTRUMENT. * src/instrmnt/nullinst.cxx: Delete. It causes confusion in the library as it declares cyg_instrument like meminst.cxx does. 2001-08-31 Nick Garnett * src/intr/intr.cxx: Clean up typo in DSR table case. dsr_table_tail and dsr_table_head were not being subscripted in a couple of places. 2001-08-23 Hugo Tyson 2001-08-20 Andrew Lunn * include/instrument_desc.h: New file. This contains the table of events used to print the nice information. It should be regenerated when the instrumentation numbers change. * src/instrmnt/meminst.cxx (cyg_instrument_msg): returns an ASCII string describing the type of event the instrumentation code logged. * include/instrmnt.h: Added function prototype. * cdl/instrument.cdl: Configury for enabling the new function, and optionally rebuilding its header file and building a host tool. * host/instr/dump_instr.c: New file. A host program to print the instrumentation information in a human readable form. * host/instr/instrument.sh: New file. Script to generate table of events with textual representation. * host/instr/readme.txt: New file. Helpful information. 2001-08-23 Nick Garnett * include/kapidata.h (CYG_THREADTIMER_MEMBERS): Substituted an expicit cyg_alarm object for CYG_ALARM_MEMBERS in this definition. In some architectures (MIPS in particular) the structures need to be padded to a multiple of 64 bits. This was not happening with the macro substituted versions. This is just a temporary fix, I'll leave it to Jifl to sort out a real patch when he returns. 2001-08-23 Hugo Tyson * src/common/thread.cxx: Properly qualify Cyg_Thread::destructors array so that it builds when destructors are not used. 2001-08-23 Nick Garnett * src/sched/mlqueue.cxx: Added code to Cyg_SchedThread_Implementation::to_queue_head() to handle a NULL thread queue pointer. This compensates for a minor change in behaviour of the scheduler. 2001-08-22 Jonathan Larmour * cdl/thread.cdl: Add kernel thread destructor options. * include/kapidata.h: Add thread destructor entries to cyg_thread * include/thread.hxx (Cyg_Thread): Give per-thread data indexes their own type, cyg_data_index. Include new thread destructor data members, and new add_destructor and rem_destructor member functions. * include/thread.inl: Use a cyg_data_index for per-thread data handle. (add_destructor): New Cyg_Thread member function. (rem_destructor): Ditto. * src/common/kapi.cxx: Use cyg_data_index type for per-thread data functions. * src/common/thread.cxx (Cyg_Thread): initialise per-thread destructors if needed. Define static destructors if needed. (exit): Call destructors. (new_data_index): Use cyg_data_index type. (free_data_index): Ditto. 2001-08-22 Hugo Tyson * src/sync/mutex.cxx (Cyg_Mutex): Add initialization of the priority ceiling value in the non-dynamic protocol case. 2001-08-22 Nick Garnett * tests/intr0.c: * tests/kintr0.c: Swapped order of interrupt enable/disable calls to keep kernel happy when assertions are enabled. Otherwise the enable call complains that interrupts have not been disabled. * src/sched/mlqueue.cxx: Simplified algorithm in set_need_reschedule(). * include/smp.hxx: * include/kapidata.h: Change spinlock to be a cyg_uint32, rather than a cyg_atomic. * src/intr/intr.cxx: * include/intr.hxx: Now arrange for DSRs to be called on the same CPU as the ISR. This is necessary if the DSR needs to access per-CPU hardware (such as interrupt controllers). This is achieved by keeping a separate DSR list/table for each CPU. * tests/smp.cxx: Some modifications to make this test work in a real SMP environment. * tests/timeslice.c: * cdl/kernel.cdl: Added timeslice test. 2001-08-21 Hugo Tyson * src/sync/mutex.cxx (lock): Bugfix: a ceiling priority mutex wasn't elevated until after it had acquired the mutex. This meant it slept with a low priority, and so did not run when awakened by the release of the mutex. The fix is to elevate the potential claimant before it sleeps in contention. * tests/kmutex4.c: New testcase - very similar to kmutex3 but it loops a load more times using different mutex priority protocols. This checks that dynamically set protos do in fact behave differently from one another and as they are each intended to. * tests/kmutex3.c: Remove FIXME comments - we now test dynamic protocol. * cdl/kernel.cdl: Build the new test. 2001-08-20 Jonathan Larmour * include/kapidata.h: Reorganize most struct type definitions into macros to allow compatible layout with all G++ implementations that align non-POD types differently from included C structures. * include/kapi.h: Similarly for cyg_resolution_t. 2001-08-17 Nick Garnett * src/sched/mlqueue.cxx (timeslice): Fix timeslice_count comparison. 2001-08-16 Hugo Tyson * include/kapi.h (cyg_mutex_protocol): Tidy up names of mutex protocol type and values. These polluted rather in 'C'. * src/common/kapi.cxx (cyg_mutex_set_protocol): ditto. 2001-08-15 Hugo Tyson 2001-08-15 Andrew Lunn * src/common/kapi.c (cyg_thread_get_current_priority): Export this function into the C api. * include/kapi.h: Declaration of new function. 2001-08-14 Jonathan Larmour * src/common/kapi.cxx (cyg_spinlock_spin_intsave): Cast to istate to CYG_INTERRUPT_STATE * since that's what is needed. (cyg_spinlock_clear_intsave): Similarly. 2001-08-10 Hugo Tyson * cdl/synch.cdl: Re-organize the options for mutexes so they are active a bit more sensibly; place the default ceiling within selection of ceiling protocol, and only have a default protocol if there is more than one protocol active. * tests/mutex3.cxx: More detailed handling of the possibility of ceiling protocol instead of the inherit or none cases; we can run the test ok and treat as inherit if the ceiling prio is higher than 5, treat as none if lower than 15, and don't check anything if in between - the test runs happily. * tests/kmutex3.c (cyg_start): New test, a KAPI translation of the now-classic mutex3.cxx. * cdl/kernel.cdl: Build tests/kmutex3.c 2001-08-06 Hugo Tyson * src/sched/sched.cxx (unlock_inner): Fix assignment to current, wouldn't build if stack checking after merger from SMP branch. 2001-08-06 Andrew Lunn 2001-08-06 Hugo Tyson * src/sync/mutex.cxx: (set_protocol) Added a function to set the priority inversion protocol for a mutex. * src/common/kapi.cxx: Export the new function above and set_ceiling into the C API. * include/mutex.hxx (class Cyg_Mutex): New member function set_protocol(). * include/kapi.h (cyg_protcol): Define new emumeration for mutex priority protocol setting, and headers for the new function to set it. 2001-08-03 Nick Garnett Imported from a development branch: 2001-07-11 Nick Garnett * src/sched/mlqueue.cxx: Changed behaviour of set_need_reschedule() to a better implementation of the intended algorithm. * include/kapi.h: * src/common/kapi.cxx: Added API for controlling routing of interrupts to CPUs in SMP configurations. 2001-07-03 Nick Garnett * cdl/scheduler.cdl: * include/bitmap.hxx: * src/sched/bitmap.cxx: Fixed up bitmap scheduler so it still works within the SMP-modified scheduling infrastructure. The bitmap scheduler is not currently SMP-enabled, only single CPU configurations are supported - hence the CDL change to require this. 2001-06-29 Nick Garnett * src/sched/sched.cxx: Removed the call to Cyg_Interrupt::enable_interrupts() in Cyg_Scheduler::start_cpu(). This was a relic from the days when the interrupt enable state was not part of the thread state. Now it is, and loading the first thread will cause interrupts to be enabled. * src/intr/intr.cxx: Changed initial values of Cyg_Interrupt::disable_counter[]s to zero as a result of the change in Cyg_Scheduler::start_cpu(). * include/kapi.h: * include/kapidata.h: * src/common/kapi.cxx: Added API for using spinlocks. Largely so that it may be extended to the driver API. * include/mlqueue.hxx: * include/intr.hxx: * include/sched.hxx: Added annotations to various static variables. 2001-06-28 Nick Garnett * include/intr.hxx: * src/intr/intr.cxx: Changed behaviour of Cyg_Interrupt::disable_interrupts() and Cyg_Interrupt::enable_interrupts(). These now claim and release a spinlock in addition to disabling and enabling interrupts. The original interrupt state is also preserved and restored. This is necessary in SMP systems to allow drivers etc. to correctly synchronize with threads and DSRs that may be running on different CPUs. In the single CPU case this mechanism reduces to the original simple interrupt disable code. [Later change] Backed off addition of volatile modifier to interrupt_disable_state. * include/smp.hxx: Some minor tidies. 2001-06-27 Nick Garnett * tests/release.cxx: Added spin loop in thread1 to allow thread0 to execute its wait. This is necessary in SMP systems where the threads will execute in parallel, but is also benign in single CPU systems. * tests/mutex2.cxx: * tests/mutex3.cxx: * tests/sync3.cxx: * tests/thread2.cxx: These tests depend on predicting the behaviour of threads at different priorities to pass. In an SMP system, several threads will run in parallel, and the execution order will not be as expected. These tests are therefore disabled in SMP configurations. * src/sched/mlqueue.cxx (add_thread): Moved call to set_need_reschedule() out of test for empty queue. In SMP systems, any addition to a queue may require a reschedule on another CPU. 2001-06-22 Nick Garnett * include/mlqueue.hxx: * src/sched/mlqueue.cxx: A major change to the way in which this scheduler works in SMP systems. The previous version removed all runnable threads from the run queues when they were executing. This resulted in serious complications and messy code, particularly when dealing with priority changes and timeslicing. The new version keeps running threads in the run queues, just like the single-CPU version. The main disadvantage of this is that we may have to search past threads running on other CPUs before we find one available to run on this CPU. However, the pending count array and map mean that we only need search one run queue, and in any case the search remains bounded by the number of CPUs available. Another change is in the way that timeslicing is handled. Now, the CPU that takes the clock interrupt decrements the timeslice counts for all CPUs and if any go zero, sends a TIMESLICE message to that CPU. * src/sched/sched.cxx (unlock_inner): Removed call to requeue(), no longer needed as a result of scheduler reorganization. * src/common/thread.cxx: Added test in Cyg_Thread::exit() to check that the thread has not already been killed. This is only an issue if the thread is calling exit() when it is kill()ed from another CPU. The test is redundant in single-CPU systems, but it does no harm having it. Added code to Cyg_Thread::set_priority() to check for reschedule when another thread is being changed in priority. Added call in idle thread constructor to scheduler to install the idle thread as the default current thread for a CPU. * include/smp.hxx: Added CYG_KERNEL_CPU_TIMESLICE_INTERRUPT(), did some miscellaneous tidying. * include/instrmnt.h: Added SMP_RESCHED_SEND and SMP_RESCHED_RECV events. * cdl/kernel.cdl: Added smp test program. * tests/smp.cxx: Added this program to test SMP functionality. 2001-06-13 Nick Garnett * src/sched/sched.cxx: Removed code to set up initial current thread, this is now done in the idle thread constructor. Added code here to set up interrupts for SMP inter-processor interrupts. This is not very tidy and may need to be changed in the future. * src/sched/mlqueue.cxx: Added local set_need_reschedule() function to set the need_reschedule flag on a suitable CPU. Many more changes to cope with SMP systems. NOTE: This code has all become somthing of a mess, it need to be tidied up and the SMP-specific changes integrated better into the code. Also, timesliceing currently only works on the CPU that takes clock interrupts - this needs fixing. * src/common/thread.cxx: Moved assignment of initial current thread to here from sched.cxx. * include/smp.hxx: Changed CYG_KERNEL_CPU_INTERRUPT() CYG_KERNEL_CPU_RESCHEDULE_INTERRUPT() since there may be other interrupt types to worry about. Added annotations to scheduler data items. * include/sched.hxx: Split set_current_thread() into two functions, the original works only on the current CPU, the new one sets another CPU's current thread. This latter function is only used to prime the current threads during initialization. Added second need_reschedule() function that takes a thread argument. This is intended to be overridden by a scheduler specific function that sets the need_reschedule flag if the supplied thread is more deserving of CPU time that any current thread. * include/mlqueue.hxx: Made cyg_scheduler_set_need_reschedule() a friend of Cyg_Scheduler_Implementation class. Added override set_need_reschedule() functions. * include/kapidata.h: Added cpu field to cyg_thread structure when in SMP systems. * include/intr.hxx: * src/intr/intr.cxx: Added Cyg_Interrupt::set_cpu() and Cyg_Interrupt::get_cpu() for SMP systems. * include/instrmnt.h: Added events for INTR_GET_CPU and INTR_SET_CPU. 2001-05-29 Nick Garnett The following changes were all imported from the SMP branch: * tests/tm_basic.cxx: Modified to work in SMP configuration - mostly at present by ifdeffing out code I didn't want to fix. * include/sched.hxx: Moved scheduler lock operation into Cyg_Scheduler_SchedLock class. Converted current_thread, need_reschedule, and thread_switches into CPU indexed arrays. Added member functions to get and set these indirectly. Added start_cpu() to do per-CPU scheduler startup. * include/sched.inl: Converted scheduler lock/unlock functions to use new schedlock class. * src/sched/sched.cxx: Changed in line with sched.hxx. Added call to requeue() in unlock_inner() to restore current thread to run queue if necessary. Moved most of scheduler startup to Cyg_Scheduler::start_cpu(). Cyg_Scheduler::start() now also starts secondary CPUs in SMP systems. Added cyg_kernel_smp_startup() as entry point from HAL into kernel for secondary CPUs. * include/mlqueue.hxx: Added Cyg_RunQueue type and removed Cyg_SchedulerThreadQueue_Implementation type. Converted timeslice_count to CPU indexed array. Added requeue() member function to scheduler class. Added cpu member to thread implementation class, to record thread's current CPU. * src/sched/mlqueue.cxx: Changed behaviour when in SMP system to remove scheduled thread from run queue and replace it when preempted. Added some extra asserts, and removed some that are no longer true in an SMP system. * src/instrmnt/meminst.cxx: In SMP systems: added spinlock to protect instrument buffer, added CPU Id in top 4 bits of thread Id field. * src/common/thread.cxx: Converted to use accessor functions for need_reschedule and current_thread. Rearranged idle thread creation to create one for each CPU. * include/test/stackmon.h: Extended to handle stack usage for multiple idle threads. * include/thread.inl: Added some extra instrumentation. * include/smp.hxx: Added this file to contain all kernel SMP support. The main definitions exported by this file are spin lock and scheduler lock implementation classes, for both SMP and uniprocessor configurations. * src/intr/intr.cxx: * include/intr.hxx: Converted interrupt disable counter to CPU indexed array. In intr.cxx: added lock of scheduler lock in interrupt_end() rather than in default interrupt VSR. * cdl/kernel.cdl: Added option to enable SMP support. * include/instrmnt.h: * cdl/instrument.cdl: Added SMP instrumentation. 2001-05-25 Nick Garnett * include/intr.hxx: * src/intr/intr.cxx: Added default definition of CYGNUM_HAL_ISR_TABLE_SIZE. This is now used to declare the chain table so that architectures which have different sizes for the interrupt table and vector count will work correctly. 2001-05-22 Nick Garnett * include/sched.hxx (class Cyg_Scheduler_Base): Added annotation to sched_lock. * cdl/instrument.cdl: Rename CYGNUM_KERNEL_INSTRUMENT_BUFFER_WRAP to CYGDBG_KERNEL_INSTRUMENT_BUFFER_WRAP as it appears in the code. 2001-07-27 Jesper Skov * src/intr/intr.cxx (chain_isr): Return isr_ret so caller (which may be an arbiter) can tell if the interrupt was handled. 2001-07-26 Gary Thomas * src/common/clock.cxx (dsr): Fix problems mixing signed and unsigned values. Normally only generated warnings, but... 2001-07-09 Jonathan Larmour * include/sched.inl (unlock_reschedule): Fix commenting. * src/sched/sched.cxx: Improve description of unlock_inner(). 2001-06-21 Jonathan Larmour * src/common/thread.cxx (Cyg_Thread::Cyg_Thread): Initialize wakeup_count 2001-06-06 Hugo Tyson * tests/clocktruth.cxx: New file. A test to get a sanity check on whether the clock is accurate to wallclock time, only useful for humans to watch really. But important! 2001-05-31 Jonathan Larmour * include/thread.hxx (class Cyg_HardwareThread): Remove unused load_context() method. * include/thread.inl: Ditto. 2001-05-29 Jonathan Larmour * src/sched/bitmap.cxx (rem_thread): No need to set need_reschedule... rescheduling will happen automatically when the state changes. * src/sched/mlqueue.cxx (add_thread): No need to explicitly clear thread->queue. 2001-04-26 Nick Garnett * tests/intr0.cxx: * tests/kintr0.c: Fixed these two tests so that they work properly on architectures where CYGNUM_HAL_ISR_MIN is not zero. These include the x86 and V850. 2001-04-18 Bart Veer * tests/dhrystone.c: Fix the conditional for STDIO_FORMATTED_IO 2001-04-17 Bart Veer * tests/stress_threads.c (setup_death_alarm): Cope with synthetic target reorg * tests/except1.cxx, tests/kexcept1.c: Reenable for the synthetic target * tests/tm_basic.cxx: Reenable for the synthetic target 2001-04-17 Jesper Skov * cdl/kernel.cdl: Do cache tests on E7T. 2001-04-05 Nick Garnett * tests/flag1.cxx: Apply same changes here as were applied to kflag1 on 2000-07-17. This allows this test to run to completion in slow targets, especially simulators. * tests/stress_threads.c: Reduce run time even further in simulator runs where instrumentation is enabled. 2001-04-03 Jesper Skov * tests/dhrystone.c: Fix feature check. 2001-03-28 Jonathan Larmour * cdl/kernel.cdl: Only need to compile dbg_gdb.cxx with CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT * src/debug/dbg_gdb.cxx: Add new dbg_thread_id() function. 2001-02-23 Jonathan Larmour * include/thread.inl (attach_stack): Check for non-NULL stack base. 2001-02-11 Jonathan Larmour * tests/stress_threads.c: CYGINT_ISO_STDIO_FORMATTED_IO needs a #ifdef not an #if. * tests/dhrystone.c: Ditto. 2001-02-04 Jonathan Larmour * tests/kill.cxx: Increase delay for all targets, just in case some are slow. 2001-01-30 Hugo Tyson * src/common/clock.cxx (rem_alarm): Must clear the enabled flag; this disappeared in the changes to using clists of 2001-01-09. Symptom was that an alarm, once disabled, could never be re-attached to its counter because it claimed it already was. Plus asserts with multiple disables - "bad counter object". 2001-01-30 Hugo Tyson * src/common/thread.cxx (reinitialize): Following change of 2000-12-05, if CYGFUN_KERNEL_THREADS_STACK_CHECKING, this was using the stack_base/stack_size variables directly to reinitialize the stack area. This was wrong, and leaked store off the top and bottom of the stacks because the "buffer zone" was carved off repeatedly. Fix is to use the published APIs which compensate. 2001-01-26 Nick Garnett * include/mlqueue.hxx: * src/sched/mlqueue.cxx: Restored Cyg_ThreadQueue_Implementation::remove() since it must clear the thread's queue pointer, which the base clist class remove() does not. 2001-01-24 Jesper Skov * src/sched/mlqueue.cxx (highpri): Fix trace call. 2001-01-09 Nick Garnett * include/mlqueue.hxx: * src/sched/mlqueue.cxx: Converted to use clist.hxx list implementation. The main effect of this is to clean up the code and class definitions since much of what was part of the thread queue and thread classes now moves to the DNode and CList classes. * include/clock.hxx: * src/common/clock.cxx: Converted to use clist.hxx list implementation. This removes all the explicit list manipulation code from the counter and alarm classes, resulting in cleaner, easier to understand code. * include/kapidata.h: Adjusted cyg_alarm struct to match Cyg_Alarm using Cyg_DNode. 2000-12-22 Jonathan Larmour * include/thread.inl (check_stack): check word alignment with CYG_WORD not cyg_uint32 Add extra stack checking for when stack limits are used. (measure_stack_usage): New function to measure stack usage of the thread (attach_stack): check word alignment with CYG_WORD not cyg_uint32 Initialize stack to preset value when measuring stack usage (increment_stack_limit): Conditionalize here wrt CYGFUN_KERNEL_THREADS_STACK_CHECKING and use the version in thread.cxx instead if CYGFUN_KERNEL_THREADS_STACK_CHECKING is defined. * src/common/thread.cxx (exit): If verbose stack measurement enabled, output stack usage (increment_stack_limit): Add version of this method when CYGFUN_KERNEL_THREADS_STACK_CHECKING *is* defined. This will add padding above the stack limit as necessary. * include/thread.hxx (class Cyg_HardwareThread): Add measure_stack_usage() member * cdl/thread.cdl (CYGFUN_KERNEL_THREADS_STACK_MEASUREMENT): Add to implement stack usage measurement. * include/kapi.h (cyg_thread_measure_stack_usage): New function * src/common/kapi.cxx (cyg_thread_measure_stack_usage): New function 2000-12-08 Jonathan Larmour * cdl/thread.cdl (CYGFUN_KERNEL_ALL_THREADS_STACK_CHECKING): Requires threads list, rather than active_if them so that inference engine can do its thang. 2000-12-07 Jesper Skov * src/debug/dbg-thread-demux.c: Add comment about the use of DBG_SYSCALL_THREAD_VEC_NUM vs CYGNUM_CALL_IF_DBG_SYSCALL. 2000-12-06 Hugo Tyson * include/thread.inl (attach_stack): Additional assert check for unsigned wrap of the stack size in subtracting the signature areas' size. Also round to whole words better. 2000-12-05 Hugo Tyson * cdl/thread.cdl (CYGFUN_KERNEL_THREADS_STACK_CHECKING): New option, to control new stack check features. Enabled by default, but only active if CYGPKG_INFRA_DEBUG and CYGDBG_USE_ASSERTS anyway, plus checking *all* threads is possible, but default off, iff CYGVAR_KERNEL_THREADS_LIST. * include/thread.hxx (class Cyg_HardwareThread): Define check_stack() function. * include/thread.inl (attach_stack): Add initialization of a signature in the top and base of the stack, if so configured. (check_stack): New function to check that signature for correctness; minor re-ordering to permit more inlining. * src/sched/sched.cxx (unlock_inner): Check departing and incoming thread stacks if CYGFUN_KERNEL_THREADS_STACK_CHECKING. Also, if CYGFUN_KERNEL_ALL_THREADS_STACK_CHECKING, check all registered thread stacks. This is placed here to get executed every clocktick and other interrupts that call DSRs, rather than messing with interrupt_end() or the idle thread. 2000-12-04 Hugo Tyson * tests/kcache2.c (entry0): Make this more robust against a complete absence of useful caches. Previous change was not careful enough. 2000-12-01 Hugo Tyson * cdl/kernel.cdl: Build the kcache tests for SA11x0 family; they were being omitted by default as part of ARM family. They work on SA1110, so this should be OK. They're OK on EBSAs too. See associated fix to cache macros in SA11x0 and EBSSA HALs. * tests/kcache2.c (entry0): Fix the test; the problem was it assumed that a write to a previously unseen location would end up in the cache. It ain't so on StrongARMs. Also make tests safe wrt interrupts possibly perturbing the cache, add explicit tests for HAL_DCACHE_INVALIDATE_ALL(), ...DISABLE() and ...SYNC(), and improve the tests for cache line invalidate and store. 2000-10-30 Jesper Skov * cdl/synch.cdl: Replaced CYGINT_KERNEL_SCHEDULER_CAN_YIELD with CYGINT_KERNEL_SCHEDULER_UNIQUE_PRIORITIES. * cdl/scheduler.cdl: CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INVERSION_PROTOCOL requires CYGINT_KERNEL_SCHEDULER_UNIQUE_PRIORITIES. * tests/thread2.cxx: Use new option. * tests/klock.c: Same. * src/common/thread.cxx: Same. * src/common/clock.cxx: Same. * include/bitmap.hxx: Leave unique priority setting to CDL. * include/mlqueue.hxx: Same. * include/sched.hxx: Let CDL do sanity check of config. 2000-10-27 Jesper Skov * cdl/scheduler.cdl: Added CYGINT_KERNEL_SCHEDULER_CAN_YIELD * tests/klock.c: Avoid use of disabled features. Require scheduler that can yield. 2000-10-20 Jonathan Larmour * tests/bin_sem0.cxx: * tests/bin_sem1.cxx: * tests/bin_sem2.cxx: * tests/clock0.cxx: * tests/clock1.cxx: * tests/clockcnv.cxx: * tests/cnt_sem0.cxx: * tests/cnt_sem1.cxx: * tests/except1.cxx: * tests/flag0.cxx: * tests/flag1.cxx: * tests/intr0.cxx: * tests/kill.cxx: * tests/mbox1.cxx: * tests/mqueue1.cxx: * tests/mutex0.cxx: * tests/mutex1.cxx: * tests/mutex2.cxx: * tests/mutex3.cxx: * tests/philo.cxx: * tests/release.cxx: * tests/sched1.cxx: * tests/sync2.cxx: * tests/sync3.cxx: * tests/testaux.hxx: * tests/thread0.cxx: * tests/thread1.cxx: * tests/thread2.cxx: * tests/tm_basic.cxx: Make sure default priority constructors have been invoked. * include/intr.hxx (class Cyg_Interrupt): Make dsr_count volatile to prevent a potential race condition with overzealous C compilers. 2000-10-13 Nick Garnett * src/sched/sched.cxx (unlock_inner): Added condition to test for DSRs to only call DSRs when the scheduler lock is making a 0->1 transition. Otherwise there is the danger of calling DSRs when the scheduler lock is > 1. This violates our original assumptions about how the scheduler lock worked with respect to DSR. * src/intr/intr.cxx (call_pending_DSRs): Added assert to check that DSRs are only called when the scheduler lock is exactly 1. 2000-10-13 Jesper Skov * include/intr.hxx: Fixing syntax mistake; volatile keyword must appear after the type for it to affect the pointer variable. * src/intr/intr.cxx: Same. Remove volatile from local block. 2000-10-05 Jesper Skov * src/intr/intr.cxx: Made dsr_table_tail volatile as well. * include/intr.hxx: Ditto. 2000-10-05 Nick Garnett * src/sched/sched.cxx: * include/sched.hxx: Converted asr_inhibit from a bool to a counter. This is necessary to permit nesting of ASR inhibiting functions. 2000-10-04 Jesper Skov * include/intr.hxx: Made dsr_list volatile. * src/intr/intr.cxx: Same. Also fix compiler warning. 2000-09-25 Nick Garnett * src/sched/mlqueue.cxx: Added test for current thread not runnable in Cyg_Scheduler_Implementation::timeslice(). This is possible if a prior DSR has caused the current thread to be descheduled. Added an assert to Cyg_ThreadQueue_Implementation::rotate() for additional paranoia. (This problem was originally identified and fixed (differently) by Andrew Lunn .) 2000-09-13 Jesper Skov * tests/kexcept1.c (cause_exception): Use separate cause_fpe function. * tests/except1.cxx (cause_exception): Same. * tests/kexcept1.c (cause_exception): Do not use division at all. * tests/except1.cxx (cause_exception): Same. * tests/kexcept1.c (cause_exception): Do not cause div-by-zero. * tests/except1.cxx (cause_exception): Same. 2000-09-11 Jonathan Larmour * cdl/instrument.cdl (CYGVAR_KERNEL_INSTRUMENT_EXTERNAL_BUFFER): Bring this option back from the dead 2000-09-08 Nick Garnett * include/sched.hxx: * include/sched.inl: Added Cyg_Scheduler::unlock_reschedule() function. This decrements the scheduler lock by one but also permits the current thread to be rescheduled if it ready to sleep, or there is a higher priority thread ready to run. This is to support use of various synchronization objects while the scheduler lock is claimed. * src/sched/sched.cxx (unlock_inner): Modified precondition to allow for functionality of unlock_reschedule(). * src/sched/mlqueue.cxx: Now uses Cyg_SchedulerThreadQueue_Implementation for all runqueue pointers. It was using Cyg_ThreadQueue_Implementation in some places which meant we were trying to sort the run queues! Changed yield() so it can be called with the scheduler lock claimed. Changed Cyg_Scheduler_Implementation::timeslice() to rotate the queue itself rather than call yield(). The changes to yield() make it unsafe to call here any more. * include/mlqueue.hxx (class Cyg_SchedulerThreadQueue_Implementation): Made enqueue() member public. * include/mboxt2.inl: * src/common/thread.cxx: * src/sync/mutex.cxx: * src/sync/cnt_sem2.cxx: Removed assertions for zero scheduler lock and replaced some invocations of Cyg_Scheduler::unlock() with Cyg_Scheduler::unlock_reschedule() or Cyg_Scheduler::reschedule() where appropriate. * tests/klock.c: * cdl/kernel.cdl: Added klock.c to test functionality while scheduler lock is claimed. 2000-08-17 Hugo Tyson * src/sched/sched.cxx (unlock_inner): Move an assert to some place where it's true *all* the time! There was a narrow margin where a DSR could confuse unlock_inner() by reanimating the current thread before it had a chance to sleep - hence the call appears to be pointless. Putting the assert before the DSR calls makes sense. * include/mboxt.inl: * src/sync/bin_sem.cxx: * src/sync/cnt_sem.cxx: * src/sync/flag.cxx: * src/sync/mutex.cxx: All of these now use Cyg_Scheduler::reschedule() rather than an unlock/lock pair to yield in their functions which can sleep. They therefore can be called safely and atomically with the scheduler already locked. This is a Good Thing[tm]. Since the network stack synch primitives now use this feature, the asserts that the scheduler was not locked must disappear: this change. 2000-08-07 Jonathan Larmour * include/mutex.hxx (class Cyg_Mutex): Add comment explaining presence of locked. 2000-08-04 Jonathan Larmour * tests/stress_threads.c (STACK_SIZE_HANDLER): Increase stack sizes otherwise it crashes! 2000-07-31 Jonathan Larmour * include/mempolt2.hxx: As per change of 2000-07-04, also delete - left behind accidentally 2000-07-20 Nick Garnett * include/mutex.hxx (class Cyg_Mutex): Added get_ceiling() accessor function. * src/sched/mlqueue.cxx: Fixed bug in sorted queue code that resulted in an infinite loop if the thread being inserted is of lower priority than all threads in the queue. This case is now detected early. 2000-07-17 Gary Thomas * tests/kflag1.c (FIRST_THREAD_WAIT_TIME): Parameterize thread synchronization wait times (for understanding) and adjust for incredibly slow platforms. [Previous value allowed for the test to get out of sync because the code ran so slowly] 2000-07-04 Jonathan Larmour * cdl/kernel.cdl: Remove all configury related to memory allocators, including tests. Make CYGFUN_KERNEL_API_C require CYGFUN_MEMALLOC_KAPI * include/memfixed.hxx, include/mempolt2.inl, include/mempoolt.hxx, include/mempoolt.inl, include/memvar.hxx, include/mfiximpl.hxx, include/mfiximpl.inl, include/mvarimpl.hxx, include/mvarimpl.inl, src/mem/memfixed.cxx, src/mem/memvar.cxx, tests/kmemfix1.c, tests/kmemvar1.c, tests/memfix1.cxx, tests/memfix2.cxx, tests/memvar1.cxx, tests/memvar2.cxx: Move to separate memory allocator package CYGPKG_MEMALLOC * include/kapi.h, include/kapidata.h, src/common/kapi.cxx: Remove memory allocator functionality - now implemented in CYGPKG_MEMALLOC * tests/dhrystone.c: Update configuration dependencies for new isoinfra design * tests/stress_threads.c: Likewise. Also fix early termination after DEATH_TIME_LIMIT so that allocated resources are freed, and so more appropriate statistics are reported Also update to use mallinfo() interface to memory allocator 2000-06-23 Hugo Tyson * include/kapi.h (cyg_scheduler_read_lock): New function, to return the value of the scheduler lock; this for implementing SPLX in the network stack. * src/common/kapi.cxx (cyg_scheduler_read_lock): New function. 2000-06-20 Nick Garnett * src/sched/mlqueue.cxx (Cyg_ThreadQueue_Implementation::enqueue): Rewrote code to insert threads into priority sorted queue. The original code could not cope with a queue all of whose members were lower priority than the new thread - it looped for ever. Also provided fast paths for common and easily detected cases such as adding to a single element queue and adding at the front. By taking these cases out early, we can also simplify the code to search the queue. 2000-06-16 Gary Thomas * cdl/kernel.cdl: Remove exception tests for CMA230 - not supported by hardware. 2000-06-16 Jesper Skov * src/intr/intr.cxx (chain_isr): Only call default_isr if no isrs in the chain reacted to the interrupt. 2000-06-15 Nick Garnett * include/mutex.hxx (class Cyg_Condition_Variable): Added an inline function, get_queue(), to return a pointer to the underlying thread queue. To be used mainly for comparing with a thread's current queue to decide whether it is waiting for a condition variable. * include/kapi.h: * src/common/kapi.cxx: Changed return type of cyg_semaphore_wait() to match existing behaviour of Cyg_Counting_Semaphore::wait(). Changed return type of cyg_cond_wait() to match new behaviour of Cyg_Condition_Variable::wait(). 2000-06-09 Nick Garnett * include/mutex.hxx: * src/sync/mutex.cxx: Modified non-timeout condition variable wait() API to return cyg_bool. A true result indicates that the wait() terminated normally. A false result indicates that the wait() was terminated as a result of a release() or destroy operation. For most uses this distinction is irrelevant, but in some situations it is a useful bit of information to have. Also modified timeout condition variable wait to reacquire the mutex under all circumstances. This is the correct and consistent thing to do. 2000-06-08 Jesper Skov * src/debug/dbg-thread-demux.c: Use generic HAL feature to allow ROM/RAM intercalling. 2000-06-06 Jesper Skov * tests/kcache1.c (entry0): Skip invalidate tests on TX49. Too slow. 2000-05-30 Gary Thomas * tests/dhrystone.c: Increase number of test loops for faster StrongARM platforms. 2000-05-22 Jonathan Larmour * cdl/scheduler.cdl (CYGIMP_KERNEL_SCHED_SORTED_QUEUES): Disable by default * src/sched/mlqueue.cxx (enqueue): Add to end of thread queue even when not priority ordered 2000-05-20 Jonathan Larmour * include/mqueue.hxx, include/mqueue.inl: Add POSIX-style message queue implementation * cdl/kernel.cdl: Add mqueue1 test * cdl/scheduler.cdl: Add new CYGIMP_KERNEL_SCHED_SORTED_QUEUES option * include/sema.hxx: Need thread.inl header, not just thread.hxx Make Cyg_Counting_Semaphore::peek() const since it is * src/sync/cnt_sem.cxx, src/sync/cnt_sem2.cxx, include/sema2.hxx: Make Cyg_Counting_Semaphore{2}::peek() const since it is * include/thread.hxx: don't want Cyg_Thread_queue::empty() to be marked inline in the class def, otherwise we get warnings elsewhere * include/mlqueue.hxx (Cyg_ThreadQueue_Implementation): Add set_thread_queue private method Add derived class Cyg_SchedulerThreadQueue_Implementation, and make scheduler implementation use it instead of Cyg_ThreadQueue_Implementation * src/mlqueue.cxx: Fix typo Support CYGIMP_KERNEL_SCHED_SORTED_QUEUES, i.e. allow insertion into thread queue in order of thread priority, with oldest at the front (Cyg_ThreadQueue_Implementation::set_thread_queue): Add (Cyg_SchedulerThreadQueue_Implementation::enqueue): Add, like old one, except make it FIFO instead of LIFO by inserting at end of queue 2000-05-16 Jesper Skov * tests/dhrystone.c: More loops on the TX49 2000-05-15 Jonathan Larmour * cdl/counters.cdl (CYGVAR_KERNEL_COUNTERS_CLOCK_DSR_LATENCY): Default to CYGVAR_KERNEL_COUNTERS_CLOCK_LATENCY 2000-05-04 Jonathan Larmour * include/instrmnt.h: Remove all CYG_UNUSED_PARAMs as they could cause problems when used with volatile arguments * src/intr/intr.cxx: Use CYG_UNUSED_PARAM to silence warning that appears because of the above change. 2000-05-02 Gary Thomas * tests/kintr0.c: * tests/intr0.cxx: Correct test for cases when VSR_MIN or ISR_MIN are not zero (bad assumption). 2000-05-02 Jonathan Larmour * cdl/thread.cdl (CYGNUM_KERNEL_THREADS_DATA_LIBC): Don't need libc slot. Replace with CYGNUM_KERNEL_THREADS_DATA_ERRNO slot instead. 2000-04-28 Nick Garnett * src/sched/sched.cxx (unlock_inner): A significant change to the behaviour of this function. The new_lock argument contains the value that the scheduler lock should have after this function has completed. If it is zero then the lock is being released and some extra work (running ASRs, checking for DSRs) is done before returning. If it is non-zero then it must equal the current value of the lock, and is used to indicate that we want to reacquire the scheduler lock before returning. This latter option only makes any sense if the current thread is no longer runnable, otherwise this function will do nothing. The result of this is that where we used to "blip" the scheduler lock to force a sleep, we now call reschedule(), which calls unlock_inner() with the current sched_lock value. The important difference is that there is not now the brief window between the calls where the lock is unclaimed. It also prevents ASRs being run at inopportune moments. In future this will also allow us to force threads to sleep even when they are deeply nested in the scheduler lock. * include/mutex.hxx: Added Cyg_Mutex::get_owner() to return pointer to owning thread. * include/sched.hxx: * include/sched.inl: Added new_lock argument to unlock_inner(), added reschedule(). Made set_asr_inhibit() and clear_asr_inhibit() available even when ASRs are disabled. * include/mboxt.inl: * src/sync/bin_sem.cxx: * src/sync/cnt_sem.cxx: * src/sync/flag.cxx: * src/sync/mutex.cxx: Converted instances of "blipping" the scheduler lock into calls to Cyg_Scheduler::reschedule(), which is better behaved. Some calls to set_asr_inhibit() and clear_asr_inhibit() also added in various places. 2000-04-26 Jesper Skov * tests/kcache1.c: Also to flush testing with unified caches. 2000-04-26 Jesper Skov * tests/clockcnv.cxx: * tests/dhrystone.c: Renamed 850 HAL package. 2000-04-25 Jesper Skov * tests/kcache1.c: Fixed cache check to also look for unified caches. 2000-04-19 Jesper Skov * tests/clockcnv.cxx: * tests/dhrystone.c: Only a few laps around the block on the v850... 2000-04-13 Nick Garnett * include/clock.hxx: * src/common/clock.cxx: Added Cyg_Alarm::get_times() member function to allow reading of trigger and interval values from an alarm. 2000-04-12 Nick Garnett * include/sched.hxx: * src/sched/sched.cxx: Added ASR support. * include/thread.hxx: Made Cyg_ThreadQueue::empty() an inline in class definition. * src/common/thread.cxx: Added CYG_REPORT_FUNCTION() to Cyg_Thread::exit(). * include/kapidata.h: Brought thread structures up to date with kernel objects. * cdl/thread.cdl: * cdl/scheduler.cdl: Added ASR configuration, minor tidies. 2000-04-12 Gary Thomas * src/common/kapi.cxx (cyg_scheduler_safe_lock): * include/kapi.h: Add 'cyg_scheduler_safe_lock()' function. 2000-04-12 Jesper Skov * cdl/interrupts.cdl: * cdl/scheduler.cdl: * cdl/counters.cdl: Don't let interfaces define anything. 2000-04-07 Nick Garnett * include/sched.hxx: * include/thread.inl: * src/sync/mutex.cxx: * src/sched/sched.cxx: * src/common/thread.cxx: General reorganization of priority inversion protocol support, addition of priority ceiling protocol. * include/mlqueue.hxx: * src/sched/mlqueue.cxx: Added timeslicing enable support. * cdl/thread.cdl: * cdl/synch.cdl: Reorganized priority inversion protocol configuration to permit different protocols and dynamic choice.

Was broken. 2000-01-19 Hugo Tyson * cdl/*.cdl: Add descriptions to a number of options &c which were lacking same, also tidied up other typos as noticed en passant. Also reorganized calculated opts about per-thread-data in thread.cdl; these are really for info only. 2000-01-19 Jesper Skov CR 902054 * tests/stress_threads.c: Don't assert requested priority = allocated. Allow some flexibility of handler priorities. 2000-01-13 Hugo Tyson * tests/mutex3.cxx (control_thread): Add a CYG_TEST_INIT(); Whoops! 2000-01-11 Hugo Tyson * cdl/kernel.cdl: Add new kernel test mutex3, put in to test RELAY prio inheritance extension. * tests/mutex3.cxx: New test case. It tests mutex prio inheritance - or not - in a multiple thread manner, depending only on delays and the clock, so it tests that scheduling does the right thing, rather than simply checking reported priorities. * tests/PKGconf.mak: Add new kernel test mutex3, put in to test RELAY prio inheritance extension. 2000-01-11 Hugo Tyson * cdl/synch.cdl: New config option added, (CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INHERITANCE_SIMPLE_RELAY). * include/pkgconf/kernel.h: New config option added, (CYGSEM_KERNEL_SYNCH_MUTEX_PRIORITY_INHERITANCE_SIMPLE_RELAY). It is a child of ..._PRIORITY_INHERITANCE_SIMPLE and is really only there to turn off if you really want the old implementation. * src/sync/mutex.cxx (unlock): Add call to Cyg_SchedThread::relay_priority() when relinquishing the mutex, in order to relay any raised priority to the new owner. Also count the mutex we are waiting for as well as those held for correct recovery in the case of inheriting priority then being killed, for example. * include/sched.hxx (class Cyg_SchedThread::relay_priority): New member function declared. * src/sched/sched.cxx (Cyg_SchedThread::relay_priority): New member function to implement pass-it-on or "discovered ceiling" priority inheritance extension to the simple algorithm. Also use get_current_priority() in Cyg_SchedThread::inherit_priority() to let this work. 2000-01-11 Hugo Tyson * include/clock.hxx (class Cyg_Counter::counter): make the counter volatile, otherwise a busy-wait loop for the real time clock to change never completes. 1999-12-23 Hugo Tyson * src/sched/sched.cxx (inherit_priority): Fix bug; inheriting a 2nd time would overwrite the saved initial_priority, so disinheriting had no effect. 1999-12-13 Jonathan Larmour * tests/tm_basic.cxx (run_alarm_tests): Add new measurement of latency between alarm firing and thread resume 1999-12-13 Jonathan Larmour * cdl/kernel.cdl: Fix some minor mistakes in the lists of tests to build conditionally 1999-12-08 John Dallaway * cdl/kernel.cdl: Conditionally build the tests 'stress_threads', 'kcache1' and 'kcache2'. 1999-11-30 Hugo Tyson * src/common/kapi.cxx (cyg_scheduler_lock, cyg_scheduler_unlock): assert good range for sched lock, and be defensive anyway. This is in response to a long time taken to track down a "unlocked too many times" bug. 1999-11-24 Gary Thomas * tests/tm_basic.cxx: Size tests based on available resources, using MLT files. Fall back if not available. 1999-11-22 Nick Garnett * src/sched/bitmap.cxx (Cyg_Scheduler_Implementation::add_thread): Fixed typo in assertion, and moved it to a more useful place. 1999-11-03 John Dallaway * cdl/kernel.cdl: Define all tests. 1999-10-29 Gary Thomas * tests/PKGconf.mak: Enable cache tests for Cirrus Logic boards. 1999-10-27 John Dallaway * cdl/kernel.cdl: Specify CYGPKG_KERNEL_TESTS in terms of testing source files. 1999-10-26 John Dallaway * cdl/kernel.cdl: Define initial version of CYGPKG_KERNEL_TESTS for verification purposes. 1999-10-19 John Dallaway * cdl/kernel.cdl: Define CDL options for package-specific CFLAGS. 1999-10-08 Jesper Skov * tests/kcache1.c: Fix array size. * src/sched/bitmap.cxx (add_thread): * src/sched/mlqueue.cxx (add_thread): Check for valid thread priority. 1999-10-07 John Dallaway * cdl/counters.cdl, cdl/interrupts.cdl, cdl/scheduler.cdl: Specify radio buttons using CDL interfaces. 1999-10-06 Bart Veer * cdl/scheduler.cdl: Make the schedulers mutually exclusive via a cdl_interface 1999-10-05 Jesper Skov * tests/kcache1.c: Reduced memory footprint. 1999-09-25 Jesper Skov * tests/stress_threads.c: Added date header and flush() calls. 1999-09-16 Hugo Tyson * tests/tm_basic.cxx (run_mutex_tests): Must unlock mutices before destroying, given the change below. * src/common/kapi.cxx (cyg_cond_destroy): Call the correct destructor. As it happens, it didn't matter because all these destructors do is assert the queue is empty, and the queue is the 2nd word in every case. (cyg_mutex_destroy): Call the destructor at all, so that assertions are made. 1999-09-13 Gary Thomas * src/intr/intr.cxx (call_pending_DSRs_inner): Add assert to check for valid DSR (before trying to use it). 1999-09-13 Jesper Skov * tests/stress_threads.c: Print out malloc system info.

Otherwise they take far too long and time out. 1999-08-23 Hugo Tyson * tests/intr0.cxx (vsr0): * tests/kintr0.c (vsr0): Add a comment to the effect that vsr0() is NOT a valid VSR on any known platform; VSRs must be writ in assembler. Customer requested this, the examples are rather confusing otherwise. 1999-08-23 Nick Garnett * include/pkgconf/kernel.h: * src/common/clock.cxx: * tests/tm_basic.cxx: Added CYGVAR_KERNEL_COUNTERS_CLOCK_DSR_LATENCY to enable recording of DSR latency figures. Added code controlled by this option to clock and tm_basic. Also made interrupt latency measurement primarily dependent on CYGVAR_KERNEL_COUNTERS_CLOCK_LATENCY since whether HAL_CLOCK_LATENCY is defined is not sufficient. 1999-08-17 John Dallaway * cdl/counters.cdl, cdl/interrupts.cdl, cdl/scheduler.cdl: Implement radio buttons using "FIXME radio" hack in description field for now. 1999-08-16 Jonathan Larmour * src/sload/sload.c: Rename AM32 to AM31 1999-08-12 Nick Garnett * src/debug/dbg_gdb.cxx (dbg_make_threadref): Extended test for uninitialized thread pointer. 1999-07-29 Jesper Skov * src/sync/mutex.cxx (lock): Removed assertion again.

Invalidating the Data cache can spoil clock operation, so elapsed time appears to be 0. * tests/kcache2.c (entry0): Replace the "if (0)" for having a copy-back cache with a proper test on a HAL macro. Even though I couldn't actually get those parts of the test to work on the platform I'm currently working on. * tests/PKGconf.mak (TESTS): Do build kcache1 and kcache2 for the ARM_EBSA285; it seems kosher. kcache2 does absolutely nothing, of course. 1999-07-09 Jesper Skov PR 20210, 20142 * tests/stress_threads.c: Shifted thread priorities to make room for main() at priority 0.

It's not HAL specific, and it can apply to tests outside of the kernel, which is why it's in a public include-place. It just contains inline functions which define empty if there's no handle on the symbols available, so should be safe enough. 1999-05-18 Jesper Skov * tests/stress_threads.c (main_program): Changed behavior of cyg_thread_delete caller. 1999-05-18 Hugo Tyson * include/kapi.h (cyg_thread_delete): is now a boolean function to indicate success.

Add ability to compute statistics with first datum removed which can show up cache effects. Show thread stack usage. Fix merge screwup :-( 1999-04-26 Hugo Tyson * include/kapi.h: Add missing function cyg_thread_delete(); otherwise there is no way in the C API to re-use thread memory safely. It just calls the destructor of the Cyg_Thread class. * src/common/kapi.cxx (cyg_thread_delete): Implement it. 1999-04-26 Hugo Tyson * tests/stress_threads.c: Commit a better version for Mark since I happen to have it here; having addressed the main concern of my approval process. It runs better in sims so long as the constructor execution isn't messed with, nor timeslicing nor priority inheritance. 1999-04-23 Mark Galassi * tests/stress_threads.c (setup_death_alarm): shortened the simulator time by another factor of 10, hoping that it will not slow down nightly testing for simulator platforms too much. (perform_stressful_tasks): added writing of a bit pattern to the malloc()-ed spaces. Also reduced stack requirements for threads. 1999-04-23 Hugo Tyson * src/common/timer.cxx (Cyg_Timer::activate): we must also disable the alarm when resetting it so as to remove it from its queue, so that the enable afterwards places it on the right queue instead of assuming that, being enabled, it's already there. (if not enabling, the behaviour is unchanged and correct) This was detected by uITRON tests[cx]4, with some random perms including enable CYGIMP_KERNEL_COUNTERS_MULTI_LIST, value CYGNUM_KERNEL_COUNTERS_MULTI_LIST_SIZE {8}. The PR is 19475. 1999-04-21 Hugo Tyson * tests/bin_sem1.cxx (bin_sem1_main): Doh! Use priorities 4 and 5 for the two threads so that they are unique (with a bitmap scheduler, the threads had prios 0 and 1 resp, which causes an assert in the attempt to set thread 0's prio to 1, "prios not unique").

Otherwise simple timing, and shorter timeslicing, causes failure to be reported; likewise if the kernel happens not to run entry0 first! (another checkin) (bin_sem1_main): Add conditional use of set_priority on CYGIMP_THREAD_PRIORITY as it should be. 1999-04-14 Jesper Skov * src/debug/dbg_gdb.cxx: Fixed compiler warnings, cleaned up stub requirements (removed FIX ME). 1999-04-14 Gary Thomas * include/intr.hxx: * src/intr/intr.cxx (call_pending_DSRs_inner): Rework calling of DSRs to allow calls from HAL code. This will allow for proper use of a separate interrupt stack. 1999-04-14 Mark Galassi * tests/PKGconf.mak: added an ifndef for the AEB-1 board so that stress_threads is only built conditionally. * tests/stress_threads.c: added more config smarts suggested by Jesper for his configurations. 1999-04-13 Jesper Skov PR 19822 * src/debug/dbg_gdb.cxx: Current thread's registers live in registers, not _registers. 1999-04-13 Mark Galassi * tests/stress_threads.c: simple stressing of thread creation/deletion with some memory-intensive and alarm-based tasks. This version is set so that it dies after DEATH_TIME_LIMIT seconds, currently set to 120. #undef-ing DEATH_TIME_LIMIT makes the test run forever. This is currently not working with the bitmap scheduler, probably for some simple reason, but I have not yet broken it down to see why. 1999-04-12 Jonathan Larmour * tests/except1.cxx: * tests/kexcept1.cxx: Remove now unnecessary tx39-specific setting of CYGNUM_HAL_EXCEPTION_DATA_UNALIGNED_ACCESS VSR Part of cleanup for PR 19731 1999-04-09 Hugo Tyson Generally: thread->to_queue_head() moves a thread to the head of whatever queue it is on, if relevant. This is so that a thread can change priority and then put itself at the front of its new run queue instead of the end; otherwise it yields too, which may be undesirable.

Some fine tuning of messages and layout to fit well within 80 columns. 1999-03-24 Nick Garnett * include/pkgconf/kernel.h: Fixed an ifdef error. 1999-03-24 Gary Thomas * tests/tm_basic.cxx (NTEST_THREADS): Reduce # threads so test can build on smaller machines. Also, only adjust timings by single "overhead" value instead of the more generous 2*overhead. * src/common/clock.cxx: Clock latency measurement defaults to 'off'. 1999-03-23 Nick Garnett * tests/kcache2.c: Reduced number of loops in time_ilock(). On the MN10300 and TX39 this caused the test to timeout in the testing farm. 1999-03-23 Gary Thomas * tests/tm_basic.cxx: * src/common/clock.cxx: Add 'measure_clock_latency' boolean which is used to turn clock latency measurements on/off. 1999-03-23 Nick Garnett * tests/tm_basic.cxx (run_all_tests): Changed initial delay from 100 ticks to 2. This is adequate for the purpose of letting the clock get going, while 100 ticks was too long on simulators. 1999-03-23 Hugo Tyson * tests/kcache1.c: * tests/kcache2.c: * tests/kclock1.c: * tests/kexcept1.c: * tests/kflag1.c: * tests/kmbox1.c: * tests/kmemfix1.c: * tests/kmemvar1.c: * tests/kmutex1.c: * tests/ksched1.c: * tests/ksem1.c: * tests/kthread0.c: * tests/thread0.cxx: Use CYGNUM_HAL_STACK_SIZE_TYPICAL instead of "4096" and include hal_arch.h where necessary to get it. 1999-03-22 Hugo Tyson * include/thread.inl (attach_stack): Fix typo in assert; missing comma. 1999-03-22 Jonathan Larmour * src/debug/dbg-thread-syscall.h: Update copyright 1999-03-22 Hugo Tyson * include/thread.inl: * src/common/thread.cxx: * tests/kthread1.c: * tests/testaux.hxx: * tests/thread1.cxx: * tests/thread_gdb.c: * tests/tm_basic.cxx: Use CYGNUM_HAL_STACK_SIZE_TYPICAL for the stack size instead of CYGNUM_HAL_MINIMUM_STACK_SIZE.

The value of this variable has to survive cache invalidation and does not in some testing permutations that are unoptimized. Fixes PR 19165. * include/kapi.h: Type of cyg_tick_count_t changed to cyg_uint64. Response to PR 19320. 1999-03-19 Gary Thomas * tests/tm_basic.cxx: Much better analysis of clock interrupt times. Print average deviation instead of variance. Also print "confidence" numbers which are a measure of "how likely" a particular number would be relative to the mean and min of the sample set. 1999-03-17 Gary Thomas * tests/tm_basic.cxx: Improve messages and layout. Better message for 'hardware clock tick' value. * src/common/clock.cxx: Be more careful about clock latency delta values that are used/kept - some hardware can yield incorrect values. * tests/testaux.hxx: Use HAL recommended stack size for default. 1999-03-16 Nick Garnett * src/common/thread.cxx: Removed MIPS specific definition of idle_thread_stack[]. This is so it gets the benefit of the redefinition of CYGNUM_KERNEL_THREADS_IDLE_STACK_SIZE. This definition has also been made static, since the MIPS compiler would otherwise put it in the .data section. * include/intr.hxx (class Cyg_Interrupt): Changed implementation of Cyg_Interrupt::interrupts_enabled() to test the value of disable_counter, rather than the hardware. 1999-03-15 Nick Garnett * tests/kcache1.c: * tests/kcache2.c: Added interrupt disables around cache operations. If these take too long, an inopportune interrupt can disrupt the cache contents, or result in the interrupt seeing an inconsistent world. 1999-03-15 Gary Thomas * tests/tm_basic.cxx: Improved and cleaned up messages overall. 1999-03-15 Jesper Skov PR 19504 * tests/tm_basic.cxx: Kill created threads after mutex, mbox and semaphore tests. 1999-03-12 Hugo Tyson * src/debug/dbg-thread-demux.c: Only try handling the SPARClite-SLEB vector correctly if CYG_HAL_USE_ROM_MONITOR_CYGMON ie. we are talking with CygMon.

Removed the "foo->" from various "foo->clear_timer()" calls to make this less confusing. Ditto set_timer(). Changed a "clear_timer()" call to "timer.disable()" and added one so that they affect _this_ thread, the thread which is being kill()ed or reinitialize()d rather than the killer or the resuscitator. Otherwise the alarm list can still get a loop in it when a thread's killed when waiting with a timeout and restarted soon enough. 1998-10-08 Hugo Tyson In general, these changes are to support create/delete of uITRON objects; this requires that an object can be destroyed whilst there are threads waiting on it, and that they shall be awoken with a specific return code. * include/thread.hxx: Cyg_Thread::DESTRUCT added to wake reasons, to deal with an object being destroyed whilst a thread is waiting on it; it's handled in a manner very similar to release() and BREAK wake_reason. * src/common/thread.cxx: thread_entry(): threads now exit() if the entry_point returns. Cyg_Thread() constructors now initialize wake_reason to NONE. reinitialize() clears any pending timeout before calling constructors. counted_sleep( [timeout] ) now both deal with the wake reason in general, and with DESTRUCT in particular. exit() now clears any pending timeout. kill() now force_resumes the thread first. kill() now does not explicitly remove the thread from any queue it's on; wake() does that for you anyway. delay() clears the timer just in case and handles DESTRUCT properly. DESTRUCT added to various switches for completeness. The fixes to counted_sleep()[x2] and kill() are a bugfix for PR#17688. * include/flag.hxx: * src/sync/flag.cxx: Add an argument, defaulting to 0, to the constructor which sets the initial flag value. Add handing of DESTRUCT wake reason. Add a destructor which wakes all threads with DESTRUCT wake_reason. * include/mboxt2.inl: Add handing of DESTRUCT wake reason.

Fixed cast to incorrect type. 1998-09-03 Nick Garnett * src/PKGconf.mak (COMPILE): Added debug/dbg-thread-demux.c to COMPILE list. * src/debug/dbg_gdb.cxx (dbg_threadinfo): Added first cut at providing thread state string. * src/debug/dbg-thread-syscall.h: * src/debug/dbg-thread-demux.c: Added these two files to implement the interface between Cygmon and eCos. 1998-09-03 Bart Veer * include/pkgconf/kernel.h (CYGSEM_KERNEL_MEMORY_COALESCE): * include/mvarimpl.inl (Cyg_Mempool_Variable_Implementation): Fixed typo in configuration option name. * include/pkgconf/kernel.h: Fixed type in configuration option name. Wed Sep 2 19:01:02 1998 Hugo Tyson * include/mboxt.hxx: * include/mboxt.inl: * include/mboxt2.hxx: * include/mboxt2.inl: * include/mempolt2.hxx: * include/mempolt2.inl: * include/mempoolt.hxx: * include/mempoolt.inl: * include/sema2.hxx: * src/sync/cnt_sem2.cxx: * include/flag.hxx: * src/sync/flag.cxx: * include/kapi.h: * src/common/kapi.cxx: * tests/kmbox1.c: * tests/kmemfix1.c: * tests/kmemvar1.c: * tests/mbox1.cxx: * tests/memfix1.cxx: * tests/memvar1.cxx: Memory pool (both types) and message boxes (both types) and flags and cnt_sem2-type semaphores now all have absolute timeouts instead of relative ones in the timely wait functions. uITRON has changed to add the current time itself. Kapi changes are mainly name changes to make it clear that timeouts are now absolute. The tests (incl. kapi) add in the time themselves now. 1998-09-01 Tim Goodwin * include/kapi.h: * src/common/kapi.cxx: * tests/kclock1.c: * tests/kexcept1.c: * tests/kmbox1.c: * tests/kmemfix1.c: * tests/kmemvar1.c: * tests/kmutex1.c: * tests/ksched1.c: * tests/ksem1.c: * tests/kthread0.c: * tests/kthread1.c: * src/test/kcache1.c: * src/test/kphilo.c: * tests/kphilo.c: * tests/lottery.c: Changes to cyg_thread_create() interface. Tue Sep 1 18:49:06 1998 Hugo Tyson * include/pkgconf/kernel.h: Moved and renamed CYG_DIAG_USE_DEVICE to infra and to CYGDBG_INFRA_DIAG_USE_DEVICE; kernel.h now includes infra.h as well as hal.h to ensure all its clients get the info too. * include/intr.hxx (class Cyg_Interrupt): Add static member interrupts_enabled() to poll the current status; just to avoid calling the HAL directly, really. * include/diag.h: Now just includes cyg/infra/diag.h, so that kernel-specific features can be added later - original diag.h has moved to infra, and is that includee. * src/PKGconf.mak: Trace folder and its contents elided, now in infra. * src/trace/diag.c: * src/trace/fancy.cxx: * src/trace/null.cxx: * src/trace/simple.cxx: * src/trace/tcdiag.cxx: Deleted; all moved to infra, actually. 1998-09-01 Nick Garnett * src/debug/dbg-threads-api.h: * src/debug/dbg_gdb.cxx: Converted threadref from long long to char[8] as defined by Cygmon guys. * src/common/thread.cxx: Added scheduler lock around manipulations of thread list. * include/except.hxx: Now use CYG_EXCEPTION_COUNT to size handler arrays. Mon Aug 31 17:53:12 1998 Jonathan Larmour * include/memfixed.hxx, include/mempolt2.hxx, include/mempolt2.inl, include/mempoolt.hxx, include/mempoolt.inl, include/memvar.hxx, include/mvarimpl.hxx, include/mvarimpl.inl, src/mem/memfixed.cxx, src/mem/memvar.cxx: Add new get_allocation_size() method to return the size of a previously allocated block - trivial for fixed block allocator, and requiring a bit of poking around for the variable block allocator. This is required for the C library realloc() implementation. Strictly this only uses the variable block allocator, but the API can only be enhanced by also updating the template. As a result, this also meant doing it for the fixed block allocator. Mon Aug 31 09:51:37 1998 Jesper Skov * src/debug/stubrom.c (cyg_start): Renamed from main(). Mon Aug 31 09:00:01 1998 Jesper Skov * src/common/thread.cxx: Fixed typo. 1998-08-28 Bart Veer * include/pkgconf/kernel.h, include/bitmap.hxx, include/clock.hxx, include/except.hxx, include/flag.hxx, include/instrmnt.h, include/intr.hxx, include/kapi.h, include/kapidata.h, include/mbox.hxx, include/mboxt.hxx, include/mboxt.inl, include/mboxt2.hxx, include/mboxt2.inl, include/memfixed.hxx, include/mempolt2.hxx, include/mempolt2.inl, include/mempoolt.hxx, include/mempoolt.inl, include/memvar.hxx, include/mlqueue.hxx, include/mutex.hxx, include/mvarimpl.inl, include/sched.hxx, include/sema.hxx, include/sema2.hxx, include/thread.hxx, include/thread.inl, include/pkgconf/kernel.h: src/common/clock.cxx, src/common/except.cxx, src/common/kapi.cxx, src/common/thread.cxx, src/debug/dbg_gdb.cxx, src/debug/generic-stub.c, src/instrmnt/meminst.cxx, src/instrmnt/nullinst.cxx, src/intr/intr.cxx, src/mem/memfixed.cxx, src/mem/memvar.cxx, src/sched/bitmap.cxx, src/sched/lottery.cxx, src/sched/mlqueue.cxx, src/sched/sched.cxx, src/sync/cnt_sem.cxx, src/sync/cnt_sem2.cxx, src/sync/flag.cxx, src/sync/mbox.cxx, src/sync/mutex.cxx, src/test/diag.cxx, src/test/kcache1.c, src/test/main.cxx, src/test/timer.cxx, src/test/tstmbox.cxx: tests/clock0.cxx, tests/clock1.cxx, tests/except1.cxx, tests/flag1.cxx, tests/intr0.cxx, tests/kclock0.c, tests/kclock1.c, tests/kexcept1.c, tests/kintr0.c, tests/kmbox1.c, tests/kmemfix1.c, tests/kmemvar1.c, tests/kmutex0.c, tests/kmutex1.c, tests/ksched1.c, tests/ksem0.c, tests/ksem1.c, tests/kthread0.c, tests/kthread1.c, tests/lottery.c, tests/mbox1.cxx, tests/memfix1.cxx, tests/memvar1.cxx, tests/sync3.cxx, tests/thread2.cxx : Provide configuration data and rename configuration options Fri Aug 28 15:27:31 1998 Hugo Tyson * src/trace/fancy.cxx: * src/trace/simple.cxx: * src/trace/null.cxx: Condition on newly named symbols from the infra package, whence these units will be moved soon. Fri Aug 28 09:33:17 1998 Jonathan Larmour * src/test/demo.cxx, src/test/kcache1.c, src/test/kphilo.c, src/test/main.cxx, src/test/philo.cxx, src/test/sload.c, src/test/timer.cxx, src/test/tstflag.cxx, src/test/tstmbox.cxx, src/test/tstmpf.cxx, src/test/tstmpool.cxx, src/test/tsttracc.c, src/test/tsttrace.cxx, tests/bin_sem0.cxx, tests/bin_sem1.cxx, tests/bin_sem2.cxx, tests/clock0.cxx, tests/clock1.cxx, tests/cnt_sem0.cxx, tests/cnt_sem1.cxx, tests/except1.cxx, tests/flag0.cxx, tests/flag1.cxx, tests/intr0.cxx, tests/kclock0.c, tests/kclock1.c, tests/kexcept1.c, tests/kill.cxx, tests/kintr0.c, tests/kmbox1.c, tests/kmemfix1.c, tests/kmemvar1.c, tests/kmutex0.c, tests/kmutex1.c, tests/kphilo.c, tests/ksched1.c, tests/ksem0.c, tests/ksem1.c, tests/kthread0.c, tests/kthread1.c, tests/lottery.c, tests/mbox1.cxx, tests/memfix1.cxx, tests/memfix2.cxx, tests/memvar1.cxx, tests/memvar2.cxx, tests/mutex0.cxx, tests/mutex1.cxx, tests/philo.cxx, tests/release.cxx, tests/sched1.cxx, tests/sync2.cxx, tests/sync3.cxx, tests/thread0.cxx, tests/thread1.cxx, tests/thread2.cxx: Change entry points from main() to cyg_start(), and remove return codes - while main returned an int, cyg_start() returns void. It has no meaning anyway - what could you do with the code? * src/test/tsttracc.c, src/test/tsttrace.cxx: Also change trace calls (CYG_REPORT_...) to reflect that it is a function called cyg_start with no args returning void, rather than what it was for main(argc, argv) Fri Aug 28 09:24:41 1998 Jesper Skov * src/debug/generic-stub.c: Moved strcpy/strlen from hal-stub to generic-stub. Cleaned up a bit to avoid compiler warnings. Thu Aug 27 19:22:51 1998 Hugo Tyson * tests/kphilo.c (Philosopher): * tests/philo.cxx (Philosopher): * src/test/philo.cxx (Philosopher): * src/test/kphilo.c (Philosopher): * src/common/kapi.cxx: Change CYG_RELEASE_DEBUG to CYGPKG_INFRA_DEBUG. These changes are self-contained, so they can go in right now. Thu Aug 27 15:20:31 1998 Hugo Tyson * include/mvarimpl.inl (free): Remove a couple of warning due to pointer comparison without casts in coallesce(sic.) code. 1998-08-26 Nick Garnett * include/kapidata.h: Added saved_context to cyg_hardwarethread structure to track GDB support in rest of kernel. 1998-08-25 Nick Garnett * include/pkgconf/kernel.h: Added CYGIMP_KERNEL_THREAD_GDB_SUPPORT to configure for GDB interactions with the kernel. * src/debug/dbg-threads-api.h: * src/debug/dbg_gdb.cxx: Added these files to repository to support GDB interactions with the kernel. Note that dbg-threads-api.h is a copy of a file in devo/libstub. Any changes there must be merged in here too. * src/PKGconf.mak: Added debug/dbg_gdb.cxx to COMPILE list. * include/thread.inl: * include/thread.hxx: Added support for GDB, specifically for thread-aware debugging. * include/intr.hxx: * src/intr/intr.cxx: Added an extra argument to interrupt_end(): a pointer to the saved register state. This is optionally used to provide a more interesting saved register state for GDB. Tue Aug 25 02:36:26 1998 Jonathan Larmour * include/generic-stub.h: Add void to empty prototype argument lists to silence compiler warnings Fri Aug 21 18:46:34 1998 Hugo Tyson * src/common/clock.cxx (enable): Make the maths work right if we only just set up the clock thingy. Unsigned has a lot to answer for; when the next scheduled tick was all correct, the delta was -1, which correctly rounds to zero in the division. But it isn't -1 it's 18446744073709551615 which gave a shift of 15 in the the uITRON test programs. Fri Aug 21 11:40:50 1998 Hugo Tyson * include/mboxt2.inl (put): * include/mempolt2.inl (alloc): Tidy Nick's changes (1998-07-27) for set_timer() semantics a bit, make it a bit more efficient and smaller code. Thu Aug 20 17:37:35 BST 1998 Chris Provenzano * include/mvarimpl.inl, include/pkgconf/kernel.h: Added memory coallecsing to the variable size memory allocator. This option is enabled my default. * tests/stdlib/malloc2.c: Only print 50 messages, not 500. 1998-08-20 Nick Garnett * include/pkgconf/kernel.h: Moved definition of CYG_KERNEL_USE_INIT_PRIORITY from here to hal.h. * include/thread.hxx: Changed argument to cyg_thread_entry() to CYG_ADDRWORD from CYG_ADDRESS. * include/ktypes.h: Moved constructor priority ordering stuff out to infra/cyg_type.h. * include/kapi.h: * src/common/kapi.cxx: Added name and priority parameters to cyg_thread_create() and swapped stack size and base parameters. These changes are currently protected by DAY_OF_CHAOS ifdefs and are therefore inactive. Wed Aug 19 19:06:16 1998 Jonathan Larmour * tests/bin_sem1.cxx, tests/bin_sem2.cxx, tests/cnt_sem1.cxx, tests/flag1.cxx, tests/mbox1.cxx, tests/memfix2.cxx, tests/memvar2.cxx, tests/sync2.cxx, tests/sync3.cxx, tests/thread2.cxx, tests/release.cxx, tests/kill.cxx: Reorder inclusion of thread.inl to silence warnings Wed Aug 19 18:48:03 1998 Jonathan Larmour * include/kernel.hxx: Reorder inclusion of thread.inl to silence warnings Wed Aug 19 18:21:31 1998 Jonathan Larmour * src/common/kapi.cxx, src/sync/flag.cxx: Reorder inclusion of thread.inl to silence warnings * src/sync/bin_sem.cxx, src/sync/cnt_sem.cxx, src/sync/cnt_sem2.cxx, src/sync/mbox.cxx: Add inclusion of thread.inl to silence warnings * src/common/memset.c: Make pointer arithmetic be on char *, not void * to silence warnings * include/diag.h, src/trace/diag.c: Make diag_init take void parameter, and give diag_printf explicit parameters in prototypes to silence warnings 1998-08-19 Nick Garnett * include/pkgconf/kernel.h: * src/common/thread.cxx: Added ifdef for CYGIMP_IDLE_THREAD_YIELD to support single priority configurations. Tue Aug 18 16:56:38 1998 Jonathan Larmour * include/thread.hxx, include/thread.inl: To silence compiler warnings, move register_exception inline definition from the .hxx to the .inl. Also move attach_stack to before the constructor where it is invoked from. 1998-08-18 Nick Garnett * include/pkgconf/kernel.h: Moved all HAL specific config options out to a HAL config file. * include/kapi.h: * src/common/kapi.cxx: Added cyg_scheduler_lock() and cyg_scheduler_unlock() to provide user access to the scheduler lock. Mon Aug 17 21:39:20 1998 Jonathan Larmour * include/kapi.h: Insert "void" to empty parameter lists to silence warnings Fri Aug 14 18:10:20 1998 Hugo Tyson * src/common/thread.cxx (exit): Set the state explicitly to EXITED rather than or'ing it in; should be safe cos it's what kill does in the normal case. Needed to avoid suspend sort of states persisting after death. One character changes are always aesthetically pleasing. Fri Aug 14 17:28:01 1998 Hugo Tyson * include/pkgconf/kernel.h: Add config options as below: * src/common/thread.cxx: Add asserts of CYGNUM_KERNEL_MAX_COUNTED_WAKE_COUNT_ASSERT and CYGNUM_KERNEL_MAX_SUSPEND_COUNT_ASSERT if they are defined. Also lazily tidied format of func hdrs as per code review et al. 1998-08-14 Nick Garnett * include/kapidata.h: Added support for thread names and thread housekeeping list. * src/common/delete.cxx: Added include for cyg_type.h. * include/pkgconf/kernel.h: Added CYGIMP_THREAD_NAME and CYGIMP_THREAD_LIST options. * include/thread.inl: * include/thread.hxx: Added support for thread names and thread housekeeping list. * src/common/thread.cxx: Added support for thread names and thread housekeeping list. Fixed ordering bug in Cyg_Thread::delay(). Thu Aug 13 15:33:48 1998 Jonathan Larmour * include/ktypes.h: Remove inlined new and delete as they aren't strictly permitted and they prevent a valid new and delete being defined anywhere else! * src/common/delete.cxx, src/PKGconf.mak: Add delete.cxx to provide default delete operation for when a C library isn't present 1998-07-28 Nick Garnett * include/thread.hxx, include/sched.hxx, include/mlqueue.hxx, include/lottery.hxx, include/bitmap.hxx, src/common/thread.cxx, src/sched/sched.cxx, src/sched/mlqueue.cxx, src/sched/lottery.cxx, src/sched/bitmap.cxx: Added an alternative constructor to Cyg_Thread which takes arguments in new order, and includes a scheduling parameters argument. Propagated effects of this through Cyg_SchedThread and Cyg_SchedThread_Implementation. This mostly takes the form of passing the scheduling parameters through to the constructors. 1998-07-27 Nick Garnett * src/sync/flag.cxx, src/sync/cnt_sem2.cxx, include/mempoolt.inl, include/mempolt2.inl, include/mboxt2.inl, include/mboxt.inl: Modified code in API calls that take a timeout to allow for a timeout in the past. NOTE: The timeouts have for now been left as relative delays, they should be converted to absolute timeouts. * src/common/thread.cxx: Modified code in counted_sleep to allow for a timeout in the past. Added handling of EXIT wake_reason in delay(). 1998-07-24 Nick Garnett * include/thread.inl: Reordered code in Cyg_Thread::set_timer() to init the timer after wake_reason has been assigned. * include/clock.inl: Removed Cyg_Alarm::enable(). * src/sync/mutex.cxx (Cyg_Condition_Variable::wait): Modified order of code in timed version of wait to allow for a timout in the past. * src/sync/cnt_sem.cxx (Cyg_Counting_Semaphore::wait): Modified order of code in timed version of wait to allow for a timout in the past. Also modified timeout to be absolute rather than relative. * src/common/thread.cxx (Cyg_Thread::wake): Added test for whether a thread is actually asleep before waking it. Allows us to apply wake() to awake threads without damage. * src/common/clock.cxx: Added code to Cyg_Counter::add_alarm() to deal with alarms that trigger now or in the past. Moved Cyg_Alarm::enable() here. Added code to do the right thing when reenabling previously disabled interval alarms. 1998-07-23 Nick Garnett * src/debug/stubrom.c: Added header comments. Thu Mar 26 18:25:36 1998 Jonathan Larmour * src/test/philo.cxx: Rename CYG_DEBUG ifdef to CYG_RELEASE_DEBUG Wed Mar 25 23:23:39 GMT 1998 Chris Provenzano * configure.in: Fix so non_arch.h is updated even if config.cache does exists. * include/kapi.h, include/kapidata.h, include/kernel.hxx * include/mboxt.inl, include/sched.hxx: #include instead of include * include/eccconf/kernel.h: Added. This was old devo/config.h * src/Makefile.am : Set CYG_CONFIGURATION to "" * src/test/Makefile.am : Build .gdbinit from gdbinit.in and tree from tree.in Wed Mar 25 18:24:48 1998 Jonathan Larmour * src/Makefile.am, src/common/memcpy.c, src/common/memset.c: Move memcpy and memset functions from C library into kernel to satisfy the requirements of gcc - namely it must be available at at all time. Changed memcpy and memset to sit more cleanly in the kernel, and lose all dependencies on the C library * src/Makefile.in: regenerated Fri Mar 13 18:36:42 GMT 1998 Chris Provenzano * configure.in : Add rule to get correct objcopy for target * src/test/Makefile.am : Add rule to build philo.srec Fri Mar 13 11:47:23 GMT 1998 Chris Provenzano * configure.in, non_arch.h.in, non_arch.sh Add support for the mn103000 Thu Mar 12 11:38:28 GMT 1998 David Moore * src/Makefile.am: Removed flag to leave comments in generated linker script. Thu Mar 12 10:55:20 GMT 1998 David Moore * configure.in: Fixed setting of platform variable Wed Mar 11 16:54:28 GMT 1998 Chris Provenzano * src/test/Makefile.am, tests/Makefile.am: Make sure CXXFLAGS from configure are also used Wed Mar 11 16:16:57 GMT 1998 Chris Provenzano * configure.in, non_arch.h.in. non_arch.sh: Added build support for mips * tests/Makefile.am, src/test/Makefile.am Link with -nostdlib -lgcc Wed Mar 11 14:43:36 GMT 1998 Chris Provenzano * Makefile.am, configure.in, tests/Makefile.am support building tests in the tests directory Wed Mar 11 13:18:17 GMT 1998 Chris Provenzano * acinclude.m4, stamp-h.in, non_arch.h.in, src/Makefile.am: Added to support new kernel configure/make process * Makefile.am: Modified to support new kernel configure/make process. * src/acinclude.m4, src/aclocal.m4, src/configure, src/configure.in Deleted to support new kernel configure/make process * Makefile.in, configure, aclocal.m4, src/Makefile.in, src/configure: regenerated * non_arch.sh: New shellscript to change platform/startup/debug options after a configure is done. * src/devo/config.h: include non_arch.h, for platform/startup/debug options.
