| | | | | | * mongoosev/vectorisrs/vectorisrs.c, shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just bspIo.h.

| | | | | | | | | | | | | | | | * 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. * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h. * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h. * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.

| | | | | | | | | | | | | | | * 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.

| | | | | | | | | | * 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.

| | | | | | * shared/interrupts/vectorexceptions.c: New file to decode exception code and vector appropriate NON-interrupt exception. * shared/interrupts/Makefile.am: Modified to reflect above.
* 2001-03-13 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2001-03-142-3/+22
| | | | | | | | | | | | | | | | * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs directories. * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README, mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am, mongoosev/duart/README.mguart, mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h, mongoosev/duart/mg5uart_reg.c, mongoosev/include/.cvsignore, mongoosev/include/Makefile.am, mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/.cvsignore, mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/vectorisrs.c: New files. * Makefile.am, configure.in, shared/interrupts/Makefile.am, shared/interrupts/maxvectors.c: Added support for mongoosev. * tx39/vectorisrs/vectorisrs.c: Corrected warning.

| | | | | | | | | * Added r46xx directory. * Makefile.am, configure.in: Modified to reflect addition of r46xx. * shared/interrupts/installisrentries.c: Fixed typo. * r46xx/.cvsignore, r46xx/Makefile.am, r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/vectorisrs.c: New files.
* 2000-12-13 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2000-12-132-2/+8
| | | | | | | | | | | | * 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.

* shared/.cvsignore, shared/Makefile.am, shared/cache/.cvsignore, shared/cache/Makefile.am, shared/cache/cache.c, shared/cache/cache_.h, shared/interrupts/.cvsignore, shared/interrupts/Makefile.am, shared/interrupts/installisrentries.c, shared/interrupts/isr_entries.S, shared/interrupts/maxvectors.c, tx39/.cvsignore, tx39/Makefile.am, tx39/include/.cvsignore, tx39/include/Makefile.am, tx39/include/tx3904.h: New file. 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.
