Blackfin: add support for the DBG (debug output) pseudo insn

2010-05-22T18:19:05+00:00

Another pseudo insn used by Blackfin simulators. Also factor some now common register lookup code out of the DBGA handlers. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: add support for the DBGA (debug assert) pseudo insn

2010-05-22T18:18:56+00:00

A few pseudo debug insns exist to make testing of simulators easier. Since these don't actually exist in the hardware, we have to have the exception handler take care of emulating these. This allows sim test cases to be executed unmodified under Linux and thus simplify debugging greatly. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: make hardware trace output a little more useful

2010-05-21T13:40:19+00:00

Decode the vast majority of insns that appear in the trace buffer to get a better idea of what's going on at a glance. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: remove CONFIG_DEBUG_VERBOSE from trace.c

2010-05-21T13:40:18+00:00

Now that the split traps code has moved all the verbose output to the trace.c file, we can unify all the CONFIG_DEBUG_VERBOSE handling. This gets rid of much of the crappy ifdef forest and enables usage of normal pr_xxx functions so checkpatch stops complaining. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: split kernel/traps.c

2010-05-21T13:40:17+00:00

The current kernel/traps.c file has grown a bit unwieldy as more debugging functionality has been added over time, so split it up into more logical files. There should be no functional changes here, just minor whitespace tweaking. This should make future extensions easier to manage. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: remove trailing space in messages

Blackfin: fill out the signal si_addr when sending a SIGBUS/SIGSEGV

2010-03-09T05:30:49+00:00

Some userspace applications use this member in diagnosing crashes. It also makes some LTP tests pass (i.e. the Blackfin arch behaves more like everyone else). Signed-off-by: Barry Song Signed-off-by: Mike Frysinger

Blackfin: fix up mm locking in address dumping

2010-03-09T05:30:49+00:00

The locking code in the address dumper needs to grab the mm's mmap_sem so that other CPUs do not get an inconsistent view. On UP systems this really wasn't a problem, but it is easy to trigger a race on SMP systems when another CPU removes a mapping. Signed-off-by: Graf Yang Signed-off-by: Mike Frysinger
