* PR144
* nfs/bootp_subr.c bootpc_init(): Performs a write to memory address
0 when called for the first time. This is done when trying to clear
the variable "dhcp_hostname".
* PR162
* net/if_ppp.c ppp_txdaemon(), net/if_pppvar.h pppstart(): Local
variables must not be used in a device write routines. Now
ppp_softc structure have own character for writing to device
(sc_outchar). I think that converting local variables to static
is not a right solution, because problems will occur in the case
of two or more ppp instances.
* net/ppp_tty.c pppstart(): Type of the ioffset variable must be
u_long, otherwise in the case of the big output packet endless
loop may occur.
* src/bdbuf.c (avl_insert, avl_remove): Reimplemented from scratch
to avoid using GPLed sources in RTEMS core.
* src/bdbuf.c, include/rtems/bdbuf.h: Remove "binary tree"
implementation which was used for debugging only.
* PR158
* libc/rcmd.c, libc/rcmd.c: Enable the rcmd() library call by
commenting out the parts that deal with signals. This enables
RTEMS to 'rsh' command to a server connecting fd to remote stdio.
The 'server-side' parts of this file which deal with authentication
are disabled since they are not needed.
* PR145.
* sp04/task1.c, sp04/tswitch.c: Test fails if other tasks present
in system (e.g. driver tasks). Also exit on minimum number of
switches not precise number.
* 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>
