* 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).

* rtems.ads, rtems.adb: Formatting cleaned up. Task based timer
directives added. This is Timer_Initiate_Server,
Timer_Server_Fire_After, and Timer_Server_Fire_When.

* pppd/rtemspppd.c (rtems_pppd_disconnect): Modified to avoid bringing
the link down too fast.
NOTE: Mike reports successfully running at 56K baud on a direct link.
* Update of BSP to address problems restarting, provide more
information during boot, and better handle ROM vs RAM images.
* README, include/bsp.h, start/regs.S, start/start.S,
startup/bspstart.c, startup/linkcmds, timer/timer.c: Updated
* Lots of tinkering and tuning as part of improving interrupt latency
and improving the per-task interrupt level control and FP mask handling.
With these modifications interrupt latency was measured at a worst-case
of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
RTEMS tasks in the application.
* mongoosev/README: Updated.
* mongoosev/include/mongoose-v.h: Masks modified.
* mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
software prioritization of interrupts. If a higher priority interrupt
occurs while we are looking for new interrupts, we will reinitiate the
scan of all interrupts.
* shared/interrupts/vectorexceptions.c: Removed warning and deleted
blank lines.
* cpu.c: Enhancements and fixes for modifying the SR when changing
the interrupt level.
* cpu_asm.S: Fixed handling of FP enable bit so it is properly
managed on a per-task basis, improved handling of interrupt levels,
and made deferred FP contexts work on the MIPS.
* rtems/score/cpu.h: Modified to support above changes.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.
Mike did significant testing and reports that it seems to be
more stable and handle larger packets better. This patch
replaces the termios tasks with more general pppd network
driver tasks. The functions pppinput() and pppstart() get
called from the interrupt service routine.
* libc/termios.c: Added PPCDISC.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.
