vector.
* 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.
* 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.
* mongoosev/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.

can be now be installed and processed in a uniform manner just like interrupts.
Variances between various MIPS ISA levels are not accounted for at this time.

shared maxvectors.c into a variety of CPU model specific versions to simplify
the build process and reduce depdencies. Deleted shared/interrupts/maxvectors.c
and created various CPU model versions.

the other bits set in the Peripheral Function Interrupt Mask
Register when modifying those enabled for the DUART.

Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
as he debugged this BSP using a logic analyzer. In particular,
there was a mistake where the index not offset of registers was
in the header file and the baud rate calculation was incorrect.
* r46xx/vectorisrs/vectorisrs.c (mips_get_cause): Corrected
constraints from general to register.
* tx39/vectorisrs/vectorisrs.c (mips_get_cause): Corrected
constraints from general to register.
* tx39/vectorisrs/vectorisrs.c: Modified to have default exception
vector handler. This should be in a separate file so the BSP can
easily override it.
* configure.in: Added new directories.
* shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
when compiling for a TX3904.
* shared/interrupts/maxvectors.c: Corrected conditional logic.
* tx39/Makefile.am: Added vectorisrs.
* tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
* tx39/vectorisrs/.cvsignore: New files. This decodes the
interrupt pending information on the TX3904 and vectors
an interrupt.
* configure.in: Added new directories.
* shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
when compiling for a TX3904.

Moved some pieces of interrupt processing from score/cpu to
libcpu/mips since many interrupt servicing characteristics are
CPU model dependent. This patch addresses the number of interrupt
sources and where the ISR prologues are located. The only way to
currently install the ISR prologues requires that the prologues
be installed into RAM.

* This is a major reworking of the mips64orion port to use
gcc predefines as much as possible and a big push to multilib
the mips port. The mips64orion port was copied/renamed to mips
to be more like other GNU tools. Alan did most of the technical
work of determining how to map old macro names used by the mips64orion
port to standard compiler macro definitions. Joel did the merge
with CVS magic to keep individual file history and did the BSP
modifications. Details follow:
* Makefile.am: Made clock and timer subdirectories conditional.
* configure.in: Ditto.
* clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
* clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)
Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain:
* Modifications, (minor) corrections, cleanups to most existing
Makefile.ams
* Adds automake support to all remaining BSPs which have not yet been
converted to automake.
* Makefile.am for all remaining wrapup/Makefile.ams
being set to 0 to indicate that there should be no Clock Tick. This
was used by the Timing Tests to avoid clock tick overhead perturbing
execution times. Now the Timing Tests simply leave the Clock Tick
Driver out of the Device Driver Table.
which does the following:
* some cleanups, fixes, addtions to the libbsp automake transition
patches
* The missing Automake transistion patches all libcpu/<cpu>/<variant>/*
previously not yet been converted to automake (libcpu/powerpc,
libcpu/hppa1.1, libcpu/mips64orion, libcpu/sparc)
=> With this patch, libcpu/*/* is under full automake control.
NOTES:
* This patch is tested by building for random set of bsps affected by
this patch, but not tested for all BSPs.
* The parts of this patch related to libcpu/powerpc fix many small bugs
inside of those Makefiles.
* Have a look into libcpu/powerpc/mpc6xx/, which is in rather bad shape,
IMO. Obviously most subdirectories seem to be build but are not included
into libcpu.a by wrapup/Makefile. Addtionally, no actual BSP uses this
cpu-variant subdirectory. Furthermore libcpu/powerpc/mpc6xx has a
different directory layout than all other powerpc/<variant>/
directories.
Joel's note: I agree but the issue is that there is a conflict between
including timer or clock in libcpu/XXX/wrapup/Makefile.* and letting
a BSP specifically decide to pick it up. There is no clear solution
to this at the moment.
particular, using bsp.h, or getting information from the BSP which
should properly be obtained from RTEMS is forbidden. This is
necessary to strengthen the division between the BSP independent
parts of RTEMS and the BSPs themselves. This started after
comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
The changes primarily eliminated the need to include bsp.h and
peeking at BSP_Configuration. The use of Cpu_table in each
BSP needs to be eliminated.
