* cpu_asm.S: Fixed a sneaky return from int w/ ints disabled bug.
* rtems/score/cpu.h: Fixed register numbering in comments and made
interrupt enable/disable more robust.
* shared/interrupts/installisrentries.c: Added support for debug
exception vector.
* shared/interrupts/isr_entries.S: Added support for debug exception
vector.
* mips-stub.c: Debugged & tweaked the gdb command processing,
zbreak stuff, breakpoint and step code. Implemented 'T' command
support and debugged remote gdb support w/ the Mongoose bsp.
Added the memory segment support.
* memlimits.h: Disabled all contents in favor of memory sement
support. This file could probably go away.
* rtems-stub-glue.c (rtems_gdb_index_to_stub_id()): New routine.
rtems_gdb_stub_get_register_from_context(): Implemented MIPS version.
rtems_gdb_stub_get_offsets(): Implemented MIPS version.
* README: Updated.
* startup/gdb-support.c: Added calls into the mips-support gdb stub
for configuring the memory regions. Any bsp that wants to use the
gdbstub will need to do something similar.
* startup/Makefile.am: Added shared/gdbstub directory to include path.
* cpu_asm.S: Added support for the debug exception vector, cleaned
up the exception processing & exception return stuff. Re-added
EPC in the task context structure so the gdb stub will know where
a thread is executing. Should've left it there in the first place...
* idtcpu.h: Added support for the debug exception vector.
* cpu.c: Added ___exceptionTaskStack to hold a pointer to the
stack frame in an interrupt so context switch code can get the
userspace EPC when scheduling.
* rtems/score/cpu.h: Re-added EPC to the task context.
* src/pthreadonce.c: Task is not preemptable while running a
pthread_once init function. This is slightly less heavy handed
than disabling dispatching and seems better than consuming a mutex.
* libc/gxx_wrappers.c: Task is not preemptable while running a
pthread_once init function. This is slightly less heavy handed
than disabling dispatching and seems better than consuming a mutex.
* start/start.S: Added kseg1 test to enable cache flush code
* bsp_specs: Added -qnostartfile to disable including bsp's start.o
* startup/bspstart.c: Made clear_cache actually work, tweaked cpu
init to only turn on whats needed.
* startup/gdb-support.c: Added calls to uart 2 for gdb stub I/O and
a handy init function.
* cpu_asm.S: Fixed exception return address, modified FP context
switch so FPU is properly enabled and also doesn't screw up the
exception FP handling.
* idtcpu.h: Added C0_TAR, the MIPS target address register used for
returning from exceptions.
* iregdef.h: Added R_TAR to the stack frame so the target address
can be saved on a per-exception basis. The new entry is past the
end of the frame gdb cares about, so doesn't affect gdb or cpu.h
stuff.
* rtems/score/cpu.h: added an #ifdef so cpu_asm.S can include it
to obtain FPU defines without systax errors generated by the C
defintions.
* cpu.c: Improved interrupt level saves & restores.
* console/sci.c, console/sci.h,
console/console.c: Added new SCI driver.
* start/start.c: Removed file.
* start/start.S: New file, the asm portion of the updated start code.
* start/configure.am: Added start.S, removed start.c
* startup/start_c.c: New file, the C portion of the updated start code. Contains most of the code that was in the old start.c.
* startup/configure.am: Added start_c.c to C_FILES.
* include/bsp.h: Added include <rtems/bspIo.h>
* Submitted by Victor V. Vengerov <vvv@oktet.ru> and merged
into the RTEMS source.
* ChangeLog, Makefile.am, README, configure.ac, include/Makefile.am,
include/rtems/bdbuf.h, include/rtems/blkdev.h, include/rtems/diskdevs.h,
include/rtems/ramdisk.h, include/rtems/.cvsignore, include/.cvsignore,
src/Makefile.am, src/bdbuf.c, src/blkdev.c, src/diskdevs.c,
src/ramdisk.c, src/.cvsignore, .cvsignore: New files.
* net/if_ppp.c, pppd/auth.c, pppd/chat.c, pppd/pppd.h,
pppd/sys-rtems.c: Add server with pap-authorization
capabilities as well as eliminate some warnings.
* net/radix.c: Properly handle fetching the default route when there
is no route. This was a bug in the original FreeBSD code and this
fix is from an updated version of their code.
* Significant modifications including adding thread support, the 'X'
command, and reorganizing so that target CPU independent routines
could be reused.
* gdb_if.h: Added numerous prototypes.
* mips-stub.c: Added thread support as well as 'X' command.
Also noticed that the 'P' command was from the mips protocol.
* rtems-stub-glue.c: New file. This file contains all generic
support which should be able to be reused on another target CPU.
* mips-stub.c (handle_exception): Prototype changed to be an RTEMS
entry point. Added comments about possible need to flush cache.
(mips_gdb_stub_install): New routine.
* Makefile, stubinit.S, r46kstub.ld, ioaddr.h: Removed as unused
with RTEMS.
* r46kstub.c: Renamed to mips-stub.c.
* mips-stub.c: New file -- was r46kstub.c.
* memlimits.h: New file was limits.h.
* limits.h: Removed.
* r4600.h: Eliminated need for this file.
* README: Updated.
* gdb_if.h: Added CVS Id.
* mips-stub.c: Attempt to deal with MIPS1 versus MIPS3.
* Merged r46kstub.c into RTEMS distribution without modification.
I got the code from Franz Fischer <Franz.Fischer@franz-fischer.de>
who had used this with an old version of RTEMS with the mips64orion
port of RTEMS. After adding this to the repository, I will tailor
this to work with the RTEMS exception processing model and trim
no longer needed parts.
* ChangeLog, gdb_if.h, ioaddr.h, limits.h, Makefile, mips_opcode.h,
r4600.h, r46kstub.c, r46kstub.ld, README, stubinit.S:
* isr_entries.S: Removed comment incorrectly indicating this
file was cpu_asm.S.
* vectorexceptions.c (mips_dump_exception_frame): New routine
broken out from default exception handler.
* cpu_asm.S: Enhanced to save/restore more registers on
exceptions.
* rtems/score/cpu.h (CPU_Interrupt_frame): Enhanced to list every
register individually and document when it is saved.
* idtcpu.h: Added constants for the coprocessor 1 registers
revision and status.
* include/lr33000.h, include/lr330x0.h, include/r3000.h, start/mg5.h:
New files missed in previous commit.
* timer/timer.c: Use rtems/bspIo.h not just bspIo.h.
* So many patches have been posted recently on the mailing list and
because we were unable to find correct solution to compile on various
linux distros (due to rpcgen incompatibilities), and because the coding
style of rdbg was rather inconsistant among various pieces of code, I
decided to:
1) make some cleaning regarding global coding style (using
indent + manual edits),
2) incorporate/review the paches send by various people
(S. Holford, T. Strauman),
3) Fix the bug due to varying rpcgen code generation
in remdeb_svc.c,
4) Remove some dead code,
5) Apply a patches enabling to call enterRdbg imediately
after rdbg initialization is done,
NB : the paches is huge but it is mainly due to coding styke chnages.
Only few lines of codes have been really changed and they do not impact
rdbg functionnality (AFAIKT).
