arch/sh/kernel/kgdb.c: add missing #include

2014-01-22T00:19:42+00:00

  arch/sh/kernel/kgdb.c: In function 'sleeping_thread_to_gdb_regs':
  arch/sh/kernel/kgdb.c:225:32: error: implicit declaration of function 'task_stack_page' [-Werror=implicit-function-declaration]
  arch/sh/kernel/kgdb.c:242:23: error: dereferencing pointer to incomplete type
  arch/sh/kernel/kgdb.c:243:22: error: dereferencing pointer to incomplete type
  arch/sh/kernel/kgdb.c: In function 'singlestep_trap_handler':
  arch/sh/kernel/kgdb.c:310:27: error: 'SIGTRAP' undeclared (first use in this function)
  arch/sh/kernel/kgdb.c:310:27: note: each undeclared identifier is reported only once for each function it appears in

This was introduced by commit 16559ae48c76 ("kgdb: remove #include
 from kgdb.h").

sh: kgdb: Fix up NULL pointer deref by kgdb_nmicallback.

2012-04-10T05:22:39+00:00

kgdb_nmicallback expects valid register state, so just fetch the register
state with get_irq_regs() as on other platforms.

sh: kgdb: Fill out sleeping_thread_to_gdb_regs() state.

2012-04-10T05:00:30+00:00

Presently we're using a pretty dumbed-down implementation that copies
over register state visible from the thread info, leaving the bulk of the
switch_to state uncopied.

Given that we're also depending on register bank toggling for switch_to
optimization we ought to also explicitly zero out the GP regs that reside
in an alternate bank in order to prevent handing back garbage.

There are a few extra registers that we have state for in switch_to, so
copy those over while we're at it.

sh: kgdb: Individual register get/set support.

2012-04-10T04:42:56+00:00

This updates sh following the generic kgdb changes adding support
for individual register get/set for kgdb/kdb use.

sh: kgdb: Fix up basic SMP support.

2012-04-10T03:39:55+00:00

kgdb needs a kgdb_roundup_cpus() definition in the architecture backend,
so just copy over the MIPS version, which already does what we want.

sh: fix up fallout from system.h disintegration.

2012-03-30T10:29:57+00:00

Quite a bit of fallout all over the place, nothing terribly exciting.

kgdb,sh: update superh kgdb exception handling

2010-05-21T02:04:20+00:00

Implement kgdb_arch_pc() which adjusts the pc if it needs to be
adjusted after a software breakpoint trap.

Implement kgdb_arch_set_pc() which is a new required function in the
kgdb debug core.

When processing a single step return zero in the error exception field
so that the debug core can distinguish between a single step trap and
a breakpoint trap generically.

sh: kgdb: Rework breakpoint handling on top of notifier chain.

2009-12-22T03:44:14+00:00

This kills off kgdb's breakpoint handler and ties in to the notifier
chain instead.

sh: Kill off kgdb's magical NMI debouncing.

2009-09-01T08:45:35+00:00

The kgdb stub has traditionally tied in to the NMI slot, and manually
handled debounce. Now that we have a generic way to do this instead, all
of the stub-specific debounce silliness can be killed off.

sh: kgdb: do not reload VBR while handling debugger breackpoint

2009-08-24T07:14:03+00:00

Save the VBR allowing GDB to dump full registers set but do not reload it
as soon as the kgdb_handle_exception is invoked.
