* mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
tx39/include/tx3904.h: All exceptions were given low numbers and thus
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.
* mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
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.
* rtems/score/mips.h: Added constants for MIPS exception numbers.
All exceptions should be given low numbers and thus can be installed
and processed in a uniform manner. Variances between various MIPS
ISA levels were not accounted for.
* rtems/score/mips.h: Added constants for MIPS exception numbers.
All exceptions should be given low numbers and thus can be installed
and processed in a uniform manner. Variances between various MIPS
ISA levels were not accounted for.
* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
* mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
shared/interrupts/maxvectors.c: Now works. Significant rework
of exceptions and interrupt vectoring to clean things up.
* shared/interrupts/vectorexceptions.c: Removed.
* shared/interrupts/Makefile.am: Reflects above.
* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
* clock/clockdrv.c, console/conscfg.c: Corrected.
* include/bsp.h: Support for tm27 and addition of CPU_CLOCK_RATE.
* startup/bspstart.c: Properly set initial status register and
pending interrupts.
* timer/timer.c: Works now.
* rtems/score/cpu.h: Add the interrupt stack structure and enhance
the context initialization to account for floating point tasks.
* rtems/score/mips.h: Added the routines mips_set_cause(),
mips_get_fcr31(), and mips_set_fcr31().
* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
* configure.in: Use RTEMS_PROG_CC_FOR_TARGET([-ansi -fasm]), adapt
bspopts.h handling to other sh-BSPs.
* include/.cvsignore: Add stamp-h*, bspopts.h*.
* include/Makefile.am: Use include_HEADERS instead of H_FILES.
* startup/bspstart.c: Reworked, based on the amos BSP.
* shared/interrupts/vectorexceptions.c: New file to decode
exception code and vector appropriate NON-interrupt exception.
* shared/interrupts/Makefile.am: Modified to reflect above.
* libc/libio.c (rtems_libio_allocate): Make sure size and offset
fields are cleared on each file open. Before this field was cleared,
this resulted in the value from the last time that IOP was used
being still in place. Discovered by Andrew Bythell
<abythell@nortelnetworks.com>.
* libc/open.c: Remove redundant setting of iop->offset.
* src/imfs/memfile.c (memfile_open): Did not set iop->size
and thus the value was incorrect. Before this field was cleared,
this resulted in the value from the last time that IOP was used
being still in place. Discovered by Andrew Bythell
<abythell@nortelnetworks.com>.
* psxfile01/test.c, psxfile01/psxfile01.scn : Added test case for
open, write, reopen, append twice from Andrew Bythell
<abythell@nortelnetworks.com> that tripped an initialization
problem in the IMFS.
* lib/rtems_bsdnet_ntp.c: Modifications to make the RTEMS NTP
synchronization a little more robust -- no NTP daemon yet, but
at least it trys a little harder when the primary NTP server is down.
* start.S: Modificatins to preserve the current CWP and adjust the
WIM accordingly. This improves compatibility with the remote
debugger and the mkprom prom-builder.
* include/rtems/libio_.h, libc/chroot.c, libc/privateenv.c:
Private environment and chroot() enhancements and fixes. Comments:
+ privateenv has been modified to let at chroot() to be more
POSIX like Sergei Organov recommended.
+ A task owner lets that rtems_set_private_env() will be
called twice or more times.
+ chroot() can be called without a previous
rtems_set_private_env(); (transpanrently)
+ The second call of rtems_set_private_env() makes a internal
chroot("/") into global imfs_root.
+ chroot() runs like chdir() without a previous chdir("/") with
the global root.
+ The current directory can be in a wrong place like Linux and
many other Unices.
* modem/ppp.c, pppd/main.c, pppd/pppmain.c, pppd/rtems-ppp.c,
pppd/modem_example/modem.c, pppd/modem_example/ppp.c: Translated
Polish comments and other strings into English
* pppd/STATUS: Updated to reflect the changes
* mcp750 directory renamed new_exception processing as it
supports many more CPU models.
* configure.in, src/powerpc/Makefile.am,
src/powerpc/new_exception_processing/Makefile.am,
src/powerpc/new_exception_processing/remdeb_f.x: New files
formerly in mcp750 plus modifications.
* src/powerpc/mcp750/.cvsignore, src/powerpc/mcp750/Makefile.am,
src/powerpc/mcp750/remdeb.h, src/powerpc/mcp750/remdeb_f.x,
src/powerpc/mcp750/remdeb_svc.c, src/powerpc/mcp750/remdeb_xdr.c:
Removed when moved to new_exception_processing.
* configure.in, src/powerpc/Makefile.am,
src/powerpc/new_exception_processing/Makefile.am,
src/powerpc/new_exception_processing/remdeb_f.x: Modified as
part of this effort to add support for the MPC8xx.
* itronmbf01/itronmbf01.scn, itronmbox01/init.c,
itronsem01/itronsem01.scn, itrontime01/init.c: Various
adjustments so test output matches screens more reliably.
* devnull/devnull.c (null_initialize): Added check to
ensure that the driver is only initialized once. Otherwise,
it will abort when the device /dev/null is present.
(null_write): Do not dereference a NULL pointer.
