2013-06-13 Ilija Kocho * tests/cache.c : Fix compiler warning about variable set but not used. [ Bugzilla 1001865 ] 2012-04-25 Ilija Kocho * include/hal_stub.h, src/hal_stub.c, src/thread-packets.c: NUMREGS replaced by HAL_STUB_REGISTERS_SIZE in thread-packets.c [Bugzilla 1001558] 2012-03-14 Grant Edwards * src/generic-stub.c (process_query): Fix compiler warning about variable that is set but not used (only used in conditionally compiled code). [ Bugzilla 1001535 ] 2012-03-09 Sergei Gavrikov * src/hal_if.c (hal_ctrlc_check): Fix compiler warning about variable that is set but not used (isr_ret has been removed). 2011-01-13 John Dallaway * cdl/hal.cdl: Add a CDL interface to control whether interrupt state must be saved. [ Bugzilla 1001111 ] * cdl/debugging.cdl: Implement the new interface within GDB Ctrl-C break options. * src/hal_if.c: Make declaration of the hal_saved_interrupt_state variable conditional on an implementation of the new CDL interface. 2010-11-20 John Dallaway * cdl/hal.cdl: Suppress -fprofile-arcs (which implies -lgcov) when generating extras.o. 2010-10-09 John Dallaway * doc/porting.sgml: Delete references to the memory layout editor. 2009-02-02 Bart Veer * cdl/hal.cdl: add CYGBLD_GLOBAL_WARNFLAGS, as part of global compiler flags update. 2008-11-21 Bart Veer * include/hal_if.h (CYGNUM_CALL_IF_available_x): fix typo in previous patch. 2008-11-20 Bart Veer * cdl/hal.cdl, include/hal_if.h, src/hal_if.c: expunge CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_CACHE and the corresponding code. 2008-05-20 Jonathan Larmour * src/thread-packets.c (threadmatch): Silence pointer signedness warning. (threadref_to_int): Ditto. * src/generic-stub.c (__mem2hex): Ditto. (__mem2hex_safe): Ditto. (__hex2mem): Ditto. (__hex2mem_safe): Ditto. * src/hal_if.c (delay_us): Ditto. * include/hal_stub.h (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION): Instead of using a local variable to avoid compiler reordering when taking the address of a label, instead call an external function. (NB making the variable volatile isn't sufficient). 2008-05-13 Chris Zimman * cdl/hal.cdl: Work around problem with current ARM EABI tools by using /dev/null as linker script. Should be safe with other tools. 2007-11-27 Bart Veer * src/hal_if.c (delay_us): use HAL_DELAY_US() rather than the fancy implementation if the port cannot provide HAL_CLOCK_READ() 2007-09-27 Grant Edwards * include/hal_endian.h (SWAP16): Fix "return value" so that it only returns data in lower 16 bits instead of 24. 2006-05-09 Andrew Lunn * src/hal_if.c (cyg_hal_diag_mangler_gdb_flush): Fix compiler warning about signed/unsigned. 2006-04-19 Alexander Neundorf * include/hal_tables.h (CYG_HAL_TABLE_{QUALIFIED_}ENTRY): added CYGBLD_ATTRIB_USED so that gcc 3.4.4 does not discard entries which are not refereced explicitly. Problem reported by Oliver Munz. 2005-06-26 Bart Veer * doc/hal.sgml: make HAL_DELAY_US() mandatory and define it to be thread-safe. 2005-05-19 Peter Korsgaard * doc/porting.sgml: Changed dead sourceware.cygnus.com links to ecos.sourceware.org. 2005-04-27 Enrico Piria * src/hal_if.c Added missing declarations of tries when compiling with CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES != 0. 2005-02-17 Jonathan Larmour * cdl/common.cdl: Add CYGBLD_HAL_LINKER_GROUPED_LIBS to allow CDL setting of libraries used for GROUP() directive in linker script. 2004-11-20 Andrew Lunn * tests/intr.c: Make the ISR call the DSR to make sure this works correctly. 2004-08-22 Gary Thomas * doc/porting.sgml: Replace [very misleading dated] comments about CygMon and platforms which use/need GDB stubs. 2004-08-12 Jani Monoses * include/hal_if.h: Make monitor locking work with CYGPKG_LWIP. 2004-05-19 John Newlin * src/hal_stub.c: (cyg_hal_gdb_interrupt) (cyg_hal_gdb_remove_break): Changed both to use _read_mem_safe/__write_mem_safe for inserting a breakpoint, and restoring the original instruction. The Xtensa architecture (and others maybe?) can have unaligned instructions, which caused unaligned load/store exception. 2004-04-22 Jani Monoses * cdl/hal.cdl : Invoke tail with stricter syntax that works in latest coreutils. 2004-02-23 Jonathan Larmour * cdl/debugging.cdl (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Included stubs should always mean saving full context both on interrupts and context swaps, so make it explicit. 2004-01-05 Gary Thomas * include/hal_if.h: Minor fixup - new 'fconfig' functions broke existing uses of CYGACC_CALL_IF_FLASH_CFG_OP. Added a new macro CYGACC_CALL_IF_FLASH_CFG_OP2 which handles new API and a wrapper to handle the old way (backwards compatability). 2003-12-21 Gary Thomas * src/hal_if.c (flash_config_op): * include/hal_if.h: New expanded functions for RedBoot 'fconfig' database. 2003-09-04 Patrick Doyle * include/hal_if.h: * src/hal_if.c (flash_fis_op): Added support for the rest of the FIS operations. 2003-08-06 Bob Koninckx * src/drv_api.c: Added definition of cyg_interrupt_post_dsr() for use in those HALs that need it. * include/hal_arbiter.h (hal_call_isr): Removed ifdef on CYGFUN_HAL_COMMON_KERNEL_SUPPORT around test and call to cyg_interrupt_post_dsr(). 2003-07-21 Nick Garnett * doc/hal.sgml: Reorganized description of clock and timer related stuff into their own section and added a piece about how to change the clock frequency. 2003-06-25 Nick Garnett * src/hal_if.c (delay_us): The first test against CYGNUM_KERNEL_COUNTERS_RTC_PERIOD is now against the period divided by two. By the time we get to this test we know that usecs can never be > usec_per_period/2 so we can double the range of period values that we can handle without overflow and use the more efficient approximation. The second test is not changed since we cannot make the same assumptions about the elapsed count. 2003-06-24 Jonathan Larmour * src/generic-stub.c (crc32): Fix crctable option name typo. * src/hal_if.c (hal_if_init): Remove kill_by_reset. (kill_by_reset): Remove, unused. (reset): ifdef test on HAL_PLATFORM_RESET and assert on reset failure. * cdl/interrupts.cdl (CYGNUM_HAL_COMMON_INTERRUPTS_STACK_SIZE): No reason to forbid people setting this quite small. 2003-06-19 Nick Garnett * src/hal_if.c (delay_us): Reorganized to cope with high frequency timers by eliminating a source of arithmetic overflow. 2003-05-06 Mark Salter * src/hal_stub.c (handle_exception_exit): Call sys_profile_reset from here. Setup to return through return_from_stub() when appropriate. (return_from_stub): New function to call CYGACC_CALL_IF_MONITOR_RETURN from thread context. * src/generic-stub.c (__handle_exception): Call exit_vec if hal_syscall_handler returns negative number. 2003-04-08 Mark Salter * src/hal_misc.c (hal_default_isr): Allow HAL to override default GDB vector matching test. 2003-04-08 Yoshinori Sato 2003-04-08 Jonathan Larmour * cdl/debugging.cdl: Allow CRC to be allocated in ROM as well as RAM. * src/generic-stub.c: as above. 2003-04-02 Gary Thomas * src/generic-stub.c: * include/generic-stub.h: Cleanup when program args are not supported (remove some unused static storage). 2003-03-03 Knud Woehler * src/hal_if.c: * include/hal_if.h: Add CYGNUM_CALL_IF_FLASH_FIS_OP. FIS read via the virtual vector table. 2003-02-24 Jonathan Larmour * cdl/hal.cdl: Fix doc links. * doc/hal.sgml: hal-common-current-doc-porting-sgml entity -> hal-common-porting-sgml in line with other docs. 2003-02-13 Mark Salter * src/gdb-fileio.h (FILEIO_O_BINARY): New flag. (FILEIO_O_TEXT): New flag. 2003-01-31 Mark Salter * include/hal_if.h: Add CYGNUM_CALL_IF_MONITOR_RETURN. 2002-12-04 Gary Thomas * cdl/hal.cdl: RAM applications should not claim (reset) version string by default. 2002-12-03 Gary Thomas * src/hal_if.c (hal_if_init): * include/hal_if.h: * cdl/hal.cdl: Allow monitor (RedBoot) version string to be exported via the virtual vector table. 2002-11-13 Gary Thomas * cdl/hal.cdl: Add CDL control over DATA cache startup mode. 2002-09-11 Mark Salter * include/hal_if.h: Add __COMMCTL_ENABLE_LINE_FLUSH and __COMMCTL_DISABLE_LINE_FLUSH. 2002-08-29 Mark Salter * include/generic-stub.h: Add defines for Z packet types. * src/bplist-dynamic.c: Add support for deferred hardware breakpoint and watchpoint insertion/deletion. This gets around gdb problem where gdb tries accessing watched memory before removing watchpoint. * src/generic-stub.c (__process_packet): Ditto. * include/hal_stub.h: Ditto. 2002-05-23 Jesper Skov * cdl/hal.cdl: Don't build tests that are not applicable with the current configuration. Added CYGINT_HAL_TESTS_NO_CACHES which allows cache tests to be suppressed. 2002-05-13 Jesper Skov * cdl/hal.cdl: Removed CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_NOT_GUARANTEED option and its dependencies. 2002-05-02 Nick Garnett * doc/hal.sgml: Added description of HAL_DELAY_US(). * doc/porting.sgml: Expanded section on architecture porting. 2002-04-30 Jonathan Larmour * src/gdb-fileio.c (cyg_hal_gdbfileio_process_F_packet): Reset retcode/errno/ctrlc status every F packet. 2002-04-23 Jesper Skov * doc/porting.sgml: Fix some typos. 2002-04-22 Jonathan Larmour * include/generic-stub.h: Prototype __getpacket(). * src/generic-stub.c: Rename getpacket() -> __getpacket(), remcomInBuffer -> __remcomInBuffer, and remcomOutBuffer -> __remcomOutBuffer throughout file, and export them (i.e. not file local). (__process_packet): Handle $F packets file I/O protocol responses. * src/gdb-fileio.c: New file to implement file I/O operations over the GDB remote protocol. * src/gdb-fileio.h: New file. Header for above. 2002-03-15 Nick Garnett * doc/porting.sgml: Platform HAL porting guide tidied up and expanded somewhat. Some work also done on variant guide. Architecture guided needs a lot more work. * doc/hal.sgml: Changed explicit section tags to recursive section tags to make any future restructuring easier. 2002-03-14 Nick Garnett * src/hal_stub.c: Add calls to HAL memory access check macros in memory access functions. * include/hal_stub.h: Added default definitions for HAL memory access check macros. 2002-03-06 Nick Garnett * tests/cache.c: Changed tests so that zero sized caches and HALs that define HAL_DCACHE_PURGE_ALL() don't cause this test to throw a compilation error. 2002-02-28 Jesper Skov * src/generic-stub.c (__handle_exception): Pay attention to return value from hal_syscall_handler. 2002-02-21 Mark Salter * src/hal_if.c (cyg_hal_diag_mangler_gdb_flush): Don't do anything if buffer is empty. 2002-02-20 Nick Garnett * doc/hal.sgml: Updated and tidied. Now includes porting guide from a separate file. * doc/porting.sgml: Added this file to contain the porting guide section of the HAL document. This is currently largely a conversion of Jesper's porting guide from the website. Unfortunately I have had no time to do much more than include it wholesale, with only minor edits. There are some notes at the end of the file describing what I would like to do. 2002-02-18 Nick Garnett * doc/hal.sgml: Restructured most of this document and rewrote large chunks of the basic HAL description stuff. Only the skeleton of the porting guided is currently done. This checkin in mostly for safety and to let others read the current state. 2002-02-06 Mark Salter * src/hal_if.c (cyg_hal_diag_mangler_gdb_control): Add flush support. (cyg_hal_diag_mangler_gdb_flush): New function to flush mangler output. (cyg_hal_diag_mangler_gdb_putc): Use new function to flush output. 2002-01-30 Hugo Tyson * include/hal_if.h (CYGNUM_FLASH_CFG_OP_CONFIG_INT): New defines for getting Flash Config options out of RedBoot using VV call CYGACC_CALL_IF_FLASH_CFG_OP(). These need to be kept uptodate with (or must override) those in RedBoot's flash_config.h Previously only used for getting an ESA. 2002-01-25 Hugo Tyson * src/generic-stub.c (__process_packet): If detach or kill, call sys_profile_reset() if BSP_SYSCALLS_GPROF are enabled, to clear out any dangerous state there. Such as a callback function pointer into application code. 2002-01-23 Jonathan Larmour * include/drv_api.h: Add cyg_drv_interrupt_mask/unmask_intunsafe * src/drv_api.c: Ditto. And modify cyg_drv_interrupt_mask/unmask to be interrupt safe. 2002-01-21 Mark Salter * include/hal_spd.h: New file. Definitions for SDRAM module SPD. 2002-01-18 Jesper Skov * src/hal_stub.c (__build_t_packet): don't declare extend_val twice. 2001-12-12 Jesper Skov * include/hal_stub.h: Add goto to the used label. * src/hal_misc.c: Added (dummy) got for label used in CYGARC_HAL_GET_RETURN_ADDRESS_BACKUP. 2001-12-05 Jonathan Larmour * src/dbg-threads-syscall.c (dbg_thread_syscall): Don't bother to deref a func ptr. The opcode could theoretically be 0x0! 2001-12-04 Richard Sandiford * src/generic-stub.c (__add_char_to_packet): Reverse check for end of buffer and end of packet to fix potential buffer overrun. 2001-12-01 Jonathan Larmour * src/dbg-threads-syscall.c (dbg_thread_syscall): check for NULL dbg_syscall_ptr. * cdl/hal.cdl: require CYGPKG_INFRA since all HALs do! 2001-11-29 Hugo Tyson * src/hal_stub.c: Enable HAL_STUB_HW_SEND_STOP_REASON_TEXT for XScale architectures per Mark's request; XScale GDB needs to know what's happening with watchpoints (= work around previous change) 2001-11-29 Hugo Tyson * src/hal_stub.c: Condition out sending the reason for hardware watchpoint stop in the stop packet as $T05watch:01234568;... most GDBs do not understand it and in fact object to it. 2001-11-23 Nick Garnett * src/generic-stub.c (__process_packet): Fixed bogosity in handling of 'r' packet. It tried to send two replies, messing up the protocol and confusing GDB. 2001-11-02 Hugo Tyson * include/hal_stub.h (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION): Permit this too to be defined externally ie. in a platform HAL. 2001-10-25 Gary Thomas * cdl/hal.cdl: * cdl/debugging.cdl: Reorg CDL a little so that GDB stub routines are only compiled when needed (instead of being compiled "empty"). 2001-10-24 Gary Thomas * cdl/hal.cdl: Add 'basic' test. * tests/basic.c: New test of some minimal HAL functionality. 2001-10-18 Gary Thomas * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): * cdl/debugging.cdl: CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is now defined as CDL 'data' flavor (tested via #if vs. #ifdef) 2001-10-17 Jesper Skov * src/generic-stub.c: Prefixed local version of memcpy and memset with _. 2001-10-17 Gary Thomas * cdl/debugging.cdl: * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Make retry/abort optional, only attemped if CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is configured to be non-zero (default now 0). 2001-10-16 Jesper Skov * include/hal_stub.h: Allow ISOINFRA/LIBC to provide string functions. 2001-10-16 Gary Thomas * include/generic-stub.h: Add prototypes for breakpoint_list functions. 2001-10-15 David Howells * include/hal_stub.h: put semicolon between goto-label and close curly. 2001-10-12 Mark Salter * src/thread-packets.c: Don't specify array sizes in extern decls. * src/hal_stub.c: Use HAL_STUB_REGISTERS_SIZE to set number of elements in register save areas. Default to NUMREGS if not defined by HAL. Allow HALs to provide specialized get_register()/put_register(). * src/generic-stub.c (stub_format_registers): Support 'p' packet. (__process_packet): Rearrange ifdefs so error is sent for unsupported Z packet types. (process_query): Add hook for HAL specific queries. (process_set): Add hook for HAL specific sets. * include/generic-stub.h: Add extern decls to quiet compiler warnings. 2001-10-11 Gary Thomas * include/generic-stub.h: * src/generic-stub.c: Improve error handling more. Make sure that packets are consumed, even if they are going to be tossed (overflow). This keeps TCP based connections going, even when the data is bad. (getpacket): Only send NAK in case of overflow. 2001-10-09 Jesper Skov * src/hal_if.c (flash_config_op): Protect with CYGARC_HAL_SAVE_GP. 2001-10-04 Jesper Skov * include/hal_endian.h: Added. Fix typo. 2001-10-03 Jonathan Larmour * include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use plain "object" because some (only some though) MIPS tools complain with %object. (CYG_HAL_TABLE_END): Ditto. 2001-10-02 Jonathan Larmour * include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use %object syntax rather than @object since @ is a comment character on ARM. gas accepts either syntax. (CYG_HAL_TABLE_END): Ditto. 2001-10-01 Gary Thomas * src/generic-stub.c (getpacket): Send back error response (E01) if packet received which overflows buffers. GDB doesn't always do much with this error, but at least it keeps the protocol moving. 2001-09-26 Gary Thomas * cdl/common.cdl: New interface CYGINT_HAL_SUPPORTS_MMU_TABLES which indicates if the HAL supports MMU tables (few do). 2001-09-25 Gary Thomas * cdl/common.cdl (CYGSEM_HAL_INSTALL_MMU_TABLES): Change to be default for ROM startup. 2001-09-20 Jesper Skov * tests/vaargs.c (cyg_start): Call CYG_TEST_INIT. 2001-09-10 Nick Garnett * include/hal_stub.h (strlen): Changed return type to size_t from int so it matches . For some reason the compiler has suddenly started complaining about the type mismatch. Strange. 2001-09-07 Nick Garnett * src/hal_stub.c (put_register): Added kludge for VR4300 targets to sign extent the PC when it is being set. This is due to the age of the VR4300 toolchain and the fact that the VR4300 is the only target to do full 64bit register saves/restores. 2001-09-07 Jesper Skov * include/hal_if.h: Fix typo in below change. 2001-09-07 Jonathan Larmour * include/hal_if.h (CYGACC_CALL_IF_DBG_SYSCALL): Define and call with correct arguments. 2001-08-24 Mark Salter * src/generic-stub.c (__process_packet): Add support for 'D' packet. (__process_packet): Check for impossible mem write length. 2001-08-17 Jonathan Larmour * cdl/hal.cdl: Add CYGINT_HAL_VIRTUAL_VECTOR_COMM_BAUD_SUPPORT interface. 2001-08-16 Gary Thomas * cdl/hal.cdl: Add CDL options to control GDB protocol retries. 2001-08-14 Gary Thomas * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Use timeout functions to allow for retries. This should improve the case where [for whatever reason] the host GDB misses or ignores a $O packet - it will get resent after a reasonable timeout. 2001-08-03 Gary Thomas 2001-08-03 Jesper Skov * include/hal_if.h: Use inline functions for calls - allowing interrupts to be disabled while services are called [CYGACC_COMM_IF_CONTROL is an exception since it's using variable arguments - so it's still a macro]. Pruned unused IF vectors: ICTRL_TABLE, EXC_TABLE, DBG_VECTOR, CPU_DATA, BOARD_DATA, SYSINFO, SET_SERIAL_BAUD. Note: this should fix bug CR 902745-CR. * cdl/hal.cdl: Removed CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_ICTRL. * src/hal_if.c (hal_if_init): Removed initialization of ICTRL_TABLE, EXC_TABLE, CPU_DATA and BOARD_DATA entries. 2001-08-03 Nick Garnett Imported from a development branch: 2001-07-11 Nick Garnett * include/drv_api.h: * src/drv_api.c: Added API for controlling routing of interrupts to CPUs in SMP configurations. 2001-06-29 Nick Garnett * include/drv_api.h: * src/drv_api.c: Added API for using spinlocks. 2001-08-03 Jesper Skov * tests/vaargs.c: Added. * cdl/hal.cdl: Added CYGPKG_HAL_BUILD_COMPILER_TESTS to allow cpp1 and vaargs tests to be compiled conditionally. 2001-07-27 Jesper Skov * tests/intr.c: Set up interrupt ISR using driver API so it works properly in chained mode in the presence of arbiters. * src/drv_api.c (chain_isr): Call default ISR when appropriate. Return ISR return value. * include/hal_arbiter.h (hal_call_isr): Added version to be used with interrupt chaining. 2001-07-24 Mark Salter * cdl/hal.cdl (CYGINT_HAL_PLF_IF_IDE): New interface which indicates platform supports IDE controller I/F macros. 2001-06-29 Jonathan Larmour * cdl/hal.cdl (CYGPKG_HAL_TESTS): Remove redundant .c extension 2001-06-29 Jesper Skov * include/hal_misc.h: Moved arbiter helper to * include/hal_arbiter.h: this file to avoid header file inclusion order problems. 2001-06-28 Jesper Skov * include/hal_misc.h (hal_call_isr): Added. Used by ISR arbiters. 2001-06-22 Gary Thomas * src/generic-stub.c (BUFMAX): Define as platform specific, thus reducing memory requirements. (__process_packet): Eliminate program arguments support until eCos makes use of them (more memory savings). 2001-06-22 Mark Salter * src/hal_stub.c (__do_copy_mem): Add goto statement to prevent compiler from moving instructions across 'err' label. 2001-06-14 Jonathan Larmour * src/generic-stub.c (__process_packet): Don't reset the board straight away with a 'r' packet. Let a 'k' packet do it instead. * src/hal_stub.c (__install_traps): Remove redundant comment. 2001-06-11 Jonathan Larmour * src/hal_if.c (delay_us): Revert below change of 2001-05-17 2001-06-05 Hugo Tyson * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): The nesting of CYGARC_HAL_SAVE_GP() and the instant-out if sending a carriage return "\r" was wrong - it scrambled the gp for the caller! Since the return-test is trivial, I simply re-ordered rather than making the exit clause complex with a restore in it. 2001-05-17 Jonathan Larmour * src/hal_if.c (delay_us): Warn if using default 2001-05-14 Jonathan Larmour * cdl/interrupts.cdl (CYGNUM_HAL_COMMON_INTERRUPTS_STACK_SIZE): Default stack size to 32K for non-kernel configs, and describe why. 2001-05-07 Gary Thomas * src/hal_if.c (hal_ctrlc_check): Only return 'true' if the ISR/DSR actually processes a ^C. Otherwise, interrupts/date can be lost on a shared channel (like an ethernet device). 2001-04-30 Gary Thomas * cdl/hal.cdl: Add configury to control initial cache behaviour. 2001-04-30 Hugo Tyson * cdl/hal.cdl: Add tests/cpp1.c to the tests list. * tests/cpp1.c: New test, to test for regressions in the tools. This one is for a CPP bug in the XScale tools where '+' binds too strongly following a ')' because it is mistaken for unary plus. 2001-04-25 Bart Veer * tests/cache.c: Fix test for cache presence. * src/drv_api.c (cyg_drv_interrupt_detach): Added missing indirection. 2001-03-28 Jonathan Larmour * include/dbg-threads-api.h: Add dbg_thread_id() function prototype. 2001-03-21 Mark Salter * src/hal_if.c (hal_if_init): Add explicit typecast when setting version. Needed when sizeof(int) < sizeof(CYG_ADDRWORD). 2001-03-21 Jesper Skov * src/hal_if.c (hal_if_init): Added warning about debugging. 2001-03-20 Jonathan Larmour * include/hal_if.h: Add argument names to __call_if_flash_cfg_op_fn_t 2001-03-16 Mark Salter * src/hal_stub.c (__build_t_packet): Add hook for adding arch-specific registers to T packet. (handle_exception_cleanup): Skip orig_registers past breakpoint so we return to original context rather than hit breakpoint again. 2001-03-16 Hugo Tyson * include/hal_if.h: Define types and slots and macros themed with the phrase CALL_IF_FLASH_CFG_OP following the pattern of what's there for the other slots. Thus CYGNUM_CALL_IF_FLASH_CFG_OP, CYGACC_CALL_IF_FLASH_CFG_OP(...) and __call_if_flash_cfg_op_fn_t are all newly defined. Also CYGNUM_CALL_IF_FLASH_CFG_GET which is the only operation supported in this initial version. Also changed many typedef'd function pointers to not include the pointerness; that way the type can be used to validate the correctness of arguments in the called function. * src/hal_stub.c (__reset): Minor change to reset function handling; pointerness of typedef removed. * src/hal_if.c (flash_config_op): New function to call flash ops in RedBoot. This is so that RedBoot can manage ethernet addresses for you, and the application can get at the data "cleanly".

Always do platform driver init from CLAIM_COMMS code. * src/hal_stub.c: Leave channel setup to CLAIM_COMMS code. * src/hal_if.c: Added null mangler that gets called via the virtual vector console comms entry and just forwards IO to the debug comms entries. This differs from setting the console channel to the same as the debug channel in that console output will go to the debug channel even if the debug channel is changed. 2001-02-07 Jesper Skov * include/hal_if.h: Allow architecture to override COMM and CALL accessor macros. 2001-02-03 Gary Thomas * src/bplist-dynamic.c (__set_breakpoint, __remove_breakpoint): Fix error introduced below when no breakpoint list defined. 2001-02-02 Mark Salter * src/generic-stub.c: __set_breakpoint and __remove_breakpoint now take a length argument. * src/bplist-dynamic.c: Support breakpoint length.

(__build_t_packet): Don't need to conditionalize on CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T as there should be no problems with the current code. * src/generic-stub.c (stub_format_registers): Likewise * include/hal_if.h (CYGACC_COMM_IF_CONTROL): Remove warning due to unnecessary use of cpp paste operator 2000-08-28 Gary Thomas * src/hal_if.c: * include/hal_if.h (hal_ctrlc_check): Define new routine to be called by interrupt handlers (DSRs) which may be using hardware shared with a debug channel. In particular, network adaptors need to call this function to see if a ^C has occurred on the network debug connection. 2000-08-24 Gary Thomas * include/hal_tables.h: Need descriminated tables (for proper sorting). 2000-08-14 Drew Moseley * src/hal_if.c: Added an extern declaration for cyg_hal_plf_comms_init. * src/bplist-dynamic.c: Only use breakpoint lists when building stubs. 2000-08-10 Drew Moseley * include/generic-stub.h: Added support for register validity checking. * src/generic-stub.c: Ditto. * src/hal_stub.c: Ditto. * include/drv_api.h: Added cyg_code_t. 2000-08-03 Gary Thomas * include/hal_if.h (CYGNUM_CALL_IF_DBG_DATA): Move to avoid conflict. 2000-07-26 Gary Thomas * src/hal_stub.c (cyg_hal_gdb_diag_putc): Ignore any characters other than the protocol chars of ACK/NAK/^C. * src/hal_if.c (hal_if_diag_init): Only reset console channel if user has configured a non-default choice. 2000-07-24 Drew Moseley * src/bplist-dynamic.c (__install_breakpoint_list): Call HAL_ICACHE_SYNC() rather than HAL_ICACHE_INVALIDATE_ALL(). 2000-07-21 Drew Moseley * src/hal_stub.c: Cleanup of #define's. * src/generic-stub.c: Rearrange the linkage between Cygmon and HAL so that Cygmon needs HAL but not vice-versa. ie HAL no longer calls any Cygmon functions. * src/hal_misc.c: Ditto. * src/bplist-dynamic.c: Use HAL macros rather than Cygmon functions for flushing the cache. Also handle the case where target_register_t is not defined. 2000-07-21 Gary Thomas * src/hal_if.c (CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS): Define to allow the number of channels to be extended by "AUX" packages. 2000-07-20 Drew Moseley * src/generic-stub.c (stub_format_registers): Make the previous patch effective only if CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T is defined so as to not affect any other targets. * src/hal_stub.c: Ditto. 2000-07-19 Drew Moseley * src/generic-stub.c (stub_format_registers): Handle the case where GDB is expecting registers larger than we are storing. ie MIPS gdb expects 64 bit registers even if we are on a 32 bit architecture. Also, handle the sign-extension correctly if necessary. * src/hal_stub.c (__build_t_packet): Ditto. 2000-07-18 Jesper Skov * src/hal_misc.c (hal_default_isr): Version gets hacked by hal_if_init - check for the hacked value. 2000-07-18 Jesper Skov * src/hal_stub.c (__mem_fault_handler): Made volatile. 2000-07-14 Drew Moseley * src/generic-stub.c: Cleanups for better coexistence with Cygmon. * include/generic-stub.h: Ditto. * include/hal_if.h: Ditto. * include/hal_stub.h: Ditto. * src/hal_stub.c: Ditto. * cdl/hal.cdl: Compile bplist-dynamic.c. * src/bplist-dynamic.c: New file for supporting breakpoints in the HAL. 2000-07-14 Gary Thomas * src/hal_if.c (delay_us): Use HAL_DELAY_US() if defined. 2000-07-07 Jesper Skov * src/hal_stub.c (initHardware): Fix #endif location. * src/hal_if.c (hal_ctrlc_isr_init): Added hack to work around a silly but critical problem. * src/hal_stub.c: Removed some CygMon conditional exclusions. * src/hal_if.c (hal_ctrlc_isr_init): Don't enable interrupts when configured as ROM monitor. 2000-07-05 Jesper Skov * cdl/debugging.cdl: Only allow CTRLC support if there's stubs or a ROM monitor to handle it.

Added DELAY_US function to vector table. Made switching of debug channel dis/enable Ctrl-c interrupts as well. Made ctrlc_isr code use new vector entries. All this amounts to a properly switchable debug channel. 2000-06-21 Jesper Skov * src/hal_stub.c: Fixed clients of vector procs tables to pass in the correct arguments. Hook O-packetizer up on procs slot reserved for IO mangler. Install mangler when necessary. * src/hal_if.c: Extended set procs functions to allow temporarily switching console procs in a safe manner. Removed debug and console wrappers - all IO happens via drivers hooked up in tables rather than through hardwired macros. Proper initialization of console proc entry. Fixed clients of vector procs tables to pass in the correct arguments. Stub now does its own vector table initialization. Added special procs slot for IO manglers. * include/hal_if.h: Define special IDs used by the set procs functions. PROCS_HANDLED removed since the procs table will now always service any port. 2000-06-21 Nick Garnett * include/hal_stub.h: Added underscore to breakinst(). * include/hal_tables.h: Added this file to contain macros for defining datatables in a systematic and extensible way. 2000-06-19 Gary Thomas * cdl/hal.cdl: Revert change below - GUARANTEED can exist with STUBS defined. 2000-06-18 Gary Thomas * cdl/hal.cdl: Use of virtual vector functions for diagnostic output must be disabled when building with stubs. Note: this lets stubs be built for platforms with guaranteed virtual vector support. 2000-06-16 Jesper Skov * include/hal_if.h: All vector-dependant features hidden when config option not enabled. * src/hal_if.c (hal_if_init): Fix warning. 2000-06-15 Jesper Skov * include/hal_if.h: Added console-include decision logic. 2000-06-15 Nick Garnett * src/drv_api.c: * include/drv_api.h: Added boolean result to cyg_drv_cond_wait() to match change to the kernel and KAPI functionality. 2000-06-14 Jesper Skov * src/hal_stub.c: Added O-packetizer used by GDB stubs for virtual vector table configs. * src/hal_misc.c (hal_default_isr): Check Ctrlc for both CTRLC or BREAK options. * src/hal_if.c: * include/hal_if.h: Define console wrappers when necessary. Platform HALs can use these by providing raw IO functions and some config data. 2000-06-09 Jesper Skov * src/hal_if.c: Implemented most of the remaining services. Some just don't have an eCos equivalent at the moment. * cdl/hal.cdl: Allow virtual_vector options to have sensible default values depending on when the platform HAL port was written. * src/hal_misc.c (cyg_hal_user_break): Also expect CygMon to provide the breakpoint service. * src/stubrom/stubrom.c (cyg_start): Reverted change. Now handled by hal_if_init. * cdl/hal.cdl: Added option for controlling use of diag services in the virtual vector table. 2000-06-08 Jesper Skov * src/stubrom/stubrom.c: Call hal_diag_init to ensure IF table entries related to diag IO get initialized. * src/hal_stub.c (cyg_hal_gdb_interrupt): save/restore GP so it can be used by MIPS platforms. Use reset function in ROM if available. * src/hal_misc.c: * include/hal_misc.h: Functions shared between HALs. More functions are likely to be moved here if appropriate. * src/hal_if.c: Interfacing related functions: table init code and function wrappers. * include/hal_if.h: ROM/RAM calling interface table definitions. The layout is a combination of libbsp and vectors already in use by some eCos platforms. * cdl/hal.cdl: Added CYGxxx_HAL_VIRTUAL_VECTOR_SUPPORT options. These are used to control whether a platform uses the new ROM/RAM calling interface. All platforms will be converted to use this, but piecemeal over a period of time, thus the requirement for selecting behavior. 2000-06-04 Gary Thomas * cdl/hal.cdl: Support variant 'pkgconf' headers. This will allow [variant] common symbols to be defined, rather than duplicating them over all platforms using that variant. 2000-05-25 Jesper Skov * cdl/debugging.cdl: Allow thread support to included for ROM monitor builds. 2000-05-22 Jesper Skov * cdl/debugging.cdl: Allow platform to prevent CTRLC inclusion. 2000-04-12 Jesper Skov * cdl/debugging.cdl: Don't let interfaces define anything. 2000-04-07 Jesper Skov * cdl/hal.cdl: Fix dependencies for stub. 2000-03-28 Jesper Skov * src/generic-stub.c (__process_packet): Added 'z' packet reply. 2000-03-28 John Dallaway * cdl/hal.cdl: Adjust documentation URLs. 2000-03-24 Jesper Skov * include/hal_stub.h: Fixed a bad function name.

Solution is to let cyg_hal_gdb_interrupt() override any previous break, and tidy up state of course. 1999-10-26 Hugo Tyson * include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION): Place the break at the address of a label within the calling context [normally hal_diag_write_char()]; this is neater and more portable; it's supported for more targets. Also use cyg_hal_place_break() to place it, define that, &c. * src/hal_stub.c (cyg_hal_gdb_place_break): New routine to specially handle the inline breakpoint. It basically does the same as cyg_hal_gdb_interrupt(), except on some platforms where you must do different things to set a bp from a non-interrupt context. 1999-10-25 Gary Thomas * src/hal_stub.c (putDebugChar, getDebugChar): When building with CygMon, these functions are defined by CygMon. 1999-10-26 John Dallaway * cdl/hal.cdl: Modify custom make rule to specify file paths relative to the package version directory. 1999-10-22 Hugo Tyson * include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION): (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION): new macros to be invoked in hal_diag routines to make atomic the code that outputs a complete GDB $O packet. This is required so that watching variables (which is implemented by stepping) and stepping itself does not try to ss through that $O output code. CASE 102327. * src/hal_stub.c (cyg_hal_gdb_break_is_set): new routine to query whether a break is set: used by step in the stubs to decide to continue instead, because we are in a critical region. (cyg_hal_gdb_running_step): communication between generic stub and here: if set, a step has been converted into a continue, so we do NOT obey cyg_hal_gdb_remove_break until it is cleared, in handle_exception_cleanup(). * src/generic-stub.c (__process_packet): If there is a break set by the hal_stub.c, convert a step to continue, and set cyg_hal_gdb_running_step to say we did so. 1999-10-22 Jesper Skov Case 102379 * src/generic-stub.c (__handle_exception): Flush and clear caches after cleaning up after single-stepping.

Need them to be thumb aware. 1999-09-13 Gary Thomas * include/pkgconf/hal.h: Add new config option to allow spurious interrupts to be ignored by the HAL. * src/generic-stub.c (__process_packet): Build in version string (date/time) for stubs in ROM to be returned via 'd' packet. 1999-09-09 Jonathan Larmour * include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Rename CYGPKG_HAL_MN10300_SIM to CYGPKG_HAL_MN10300_AM31_SIM 1999-09-07 Nick Garnett * src/dbg-threads-syscall.c (dbg_currthread_id): Fixed to return zero if dbg_currthread() returns false. Previously it could have returned a random value which would have made GDB think there had been a thread switch when there hadn't. It was particularly prone to do this in configurations where the kernel was absent. 1999-09-01 Gary Thomas * include/pkgconf/hal.h: Always include target and platform package include (pkgconf) files. 1999-08-26 Jonathan Larmour * src/generic-stub.c (__hex2mem_helper): Use target_register_t when casting to address type, rather than long Since the compiler can choose arbitrary alignment of unions, force to use byte array only Restore use of loop termination test for *hexMemSrc, just in case since that's how it used to be Increment destination, not source at end of loop (__mem2hex_helper): Use target_register_t when casting to address type, rather than long. Since the compiler can choose arbitrary alignment of unions, force to use byte array only. Therefore use single __read_mem_safe() call * src/hal_stub.c (__do_copy_mem): Reassign back from dst/src at start of each "if" clause in case we go round the loop again. 1999-08-24 Gary Thomas * src/hal_stub.c (__do_copy_mem): Move temp variables to top of function - potentially safer if there is an error. 1999-08-23 Jonathan Larmour * src/generic-stub.c (__process_packet): For 'g' and 'G' packets, when the register size differs from sizeof(target_register_t) we must adjust according to the endianness * include/hal_stub.h: Ensure __LITTLE_ENDIAN__ is defined on little-endian targets * src/hal_stub.c (__build_t_packet): Use the correct register sizes for PC and SP rather than assuming they are the same as target_register_t 1999-08-23 Gary Thomas * include/generic-stub.h: Change prototypes for internal functions. * src/hal_stub.c (__do_copy_mem): * src/generic-stub.c (__mem2hex_helper): Rework to perform aligned, multi-byte operations when conditions allow. This should handle most "hardware register" access cases. Note: there currently is no good way to force GDB to require/use such accesses. 1999-08-17 Jonathan Larmour * tests/intr.c (cyg_start): Use CYG_TEST_NA rather than a pass saying it's inapplicable 1999-08-16 Jonathan Larmour * include/pkgconf/hal.h: Rename CYG_HAL_MN10300_AM32_STDEVAL1 to CYG_HAL_MN10300_AM31_STDEVAL1 1999-08-13 Nick Garnett * src/hal_stub.c: Removed superfluous trace() extern. 1999-08-12 Nick Garnett Imported following changes from AM33 branch: 1999-07-27 Nick Garnett * src/hal_stub.c: Added support for 1 byte breakpoints. Removed invalidates for cache flushes - I am not entirely sure why we have these here, since HAL_DCACHE_SYNC() should do what we need, and these invalidates are causing a problem on the MIPS and MN10300 targets. * include/pkgconf/hal.h: Added Monitor selection for AM33. 1999-06-29 Nick Garnett * include/pkgconf/hal.h: Modified to match new MN10300 HAL organization. 1999-08-06 Jesper Skov * src/generic-stub.c (__process_packet): FLush and clear caches after call to __single_step. 1999-07-05 Jesper Skov * tests/intr.c: Don't use kernel's RTC definitions. 1999-07-02 Jesper Skov PR20157 * tests/cache.c: Print stride values, preventing timeout on slow targets. 1999-06-28 Jesper Skov * include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT): Fixed parent. 1999-06-24 Jonathan Larmour * include/pkgconf/hal.h: Clarify descriptions of CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT and CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT. 1999-06-17 Nick Garnett * include/pkgconf/hal.h: Added CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT to enable inclusion of ^C interrupt handler. Added CDL to control it. 1999-06-10 Hugo Tyson * include/pkgconf/hal.h: Add support for the PowerPC target MBX860 platform, CYG_HAL_POWERPC_MBX. 1999-06-10 Gary Thomas * src/hal_stub.c: Need to init register pointer. 1999-06-08 Jesper Skov * include/pkgconf/hal.h: Added CYG_HAL_ROM_MONITOR for EDK7708. 1999-05-31 Jesper Skov * src/hal_stub.c: Respect HAL_BREAKINST_SIZE setting. 1999-05-28 Jesper Skov * include/pkgconf/hal.h: Renamed SH platform package to edk7708. 1999-05-28 Nick Garnett * src/hal_stub.c (initHardware): Added call to HAL_STUB_PLATFORM_INIT if it is defined. * include/pkgconf/hal.h: Added a #undef for CYG_HAL_ROM_MONITOR, largely so that a stubrom permutation can define it. 1999-05-27 Nick Garnett * src/hal_stub.c: Do not call HAL_ICACHE_INVALIDATE_ALL() and HAL_DCACHE_INVALIDATE_ALL() in __instruction_cache() and __data_cache() for MIPS targets. These macros are simply duplicates. 1999-05-27 Jesper Skov * tests/cache.c: Added handling of unified caches. 1999-05-25 Jonathan Larmour * tests/cache.c: Use HAL_DCACHE_SYNC if available 1999-05-24 Jesper Skov * include/pkgconf/hal.h: Added CPU specifier for EDK board. 1999-05-21 Jesper Skov * src/hal_stub.c (__install_traps): Set exit vector to __reset. 1999-05-21 Nick Garnett * include/pkgconf/hal.h: Switched VR4300 over to using GDB STUBS monitor from PMON. 1999-05-21 Jesper Skov * tests/intr.c: Get RTC values from CYGBLD_HAL_PLATFORM_H. Ensure there are fallback definitions. * src/hal_stub.c (handle_exception_cleanup): Added optional call of HAL_STUB_PLATFORM_STUBS_FIXUP macro. 1999-05-18 Jesper Skov * src/hal_stub.c (hal_output_gdb_string): Added missing ; 1999-05-13 Nick Garnett The following changes were all made on a branch and imported into the main trunk later. 1999-05-11 Nick Garnett * include/pkgconf/hal.h: tidied up all MIPS targets to include CYGBLD_HAL_TARGET_H. This will eventually apply to all configurations. 1999-05-06 Nick Garnett * src/PKGconf.mak (COMPILE): Added dbg-threads-syscall.c. * include/dbg-thread-syscall.h: * src/dbg-threads-syscall.c: Files added to enable support for thread-awareness in GDB stub ROMs. The .h file has been moved from kernel/src/debug. 1999-04-28 Nick Garnett * src/hal_stub.c (__build_t_packet): Changed sp variable to a non-pointer type to force it to be installed in the T packet with the right size. * src/drv_api.c: Added cyg_interrupt_call_pending_DSRs() to keep HAL happy in non-kernel configurations. 1999-04-21 Nick Garnett * include/pkgconf/hal.h: Added VR4300 configury for ROM monitor use and inclusion of variant-specific configuration header. This needs some further tidying up. 1999-04-28 Bart Veer * src/PKGconf.mak: Use the new rules for generating libextras.a 1999-04-27 Jesper Skov * include/pkgconf/hal.h: GDB_BREAK support now available for ARM targets. 1999-04-16 Bart Veer * src/PKGconf.mak: * src/dummy.c: New file that can always be added to libextras.a without affecting image sizes. 1999-04-14 Jonathan Larmour * include/hal_stub.h: Make sure all functions have C linkage even in C++ 1999-04-14 Jesper Skov PR 19845 * src/generic-stub.c (__process_packet): Reset _register pointer to the exception state before attempting to set up single-step magic. 1999-04-14 Jesper Skov * include/hal_stub.h: Added declaration for __stub_copy_registers. 1999-04-14 Jesper Skov * src/hal_stub.c: Use HAL_xCACHE_IS_ENABLED if defined. 1999-04-09 Jesper Skov * src/hal_stub.c: Moved get_register and put_register here.
