124        broken out from default exception handler.
125
1262001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
127
128        * mongoosev/vectorisrs/vectorisrs.c,
129        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
130        bspIo.h.
131
1322001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
133
134        * Lots of tinkering and tuning as part of improving interrupt latency
135        and improving the per-task interrupt level control and FP mask handling.
136        With these modifications interrupt latency was measured at a worst-case
137        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
138        RTEMS tasks in the application.

140        * mongoosev/include/mongoose-v.h: Masks modified.
141        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
142        software prioritization of interrupts.  If a higher priority interrupt
143        occurs while we are looking for new interrupts, we will reinitiate the
144        scan of all interrupts.
145        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
146        blank lines.
147
1482002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

152        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
153        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
154
1552001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
156
157        * .cvsignore: Add autom4te.cache for autoconf > 2.52.

168
1692000-05-24      Joel Sherrill <joel@OARcorp.com>
170
171        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
172        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
173        tx39/include/tx3904.h: All exceptions were given low numbers and thus
174        can be now be installed and processed in a uniform manner just like interrupts.
175        Variances between various MIPS ISA levels are not accounted for at this time.
176        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
177        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
178        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
179        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
180        shared maxvectors.c into a variety of CPU model specific versions to simplify
181        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
182        and created various CPU model versions.
183
1842001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>
185
186        * clock/clock.S: Move placement of nop.

191        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
192        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
193        shared/interrupts/maxvectors.c: Now works.  Significant rework
194        of exceptions and interrupt vectoring to clean things up.
195        * shared/interrupts/vectorexceptions.c: Removed.
196
1972001-05-07      Joel Sherrill <joel@OARcorp.com>
198
199        * shared/interrupts/vectorexceptions.c: New file to decode
200        exception code and vector appropriate NON-interrupt exception. 
201        * shared/interrupts/Makefile.am: Modified to reflect above.
202
2032001-04-20      Joel Sherrill <joel@OARcorp.com>
204
205        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
206        the other bits set in the Peripheral Function Interrupt Mask
207        Register when modifying those enabled for the DUART.

209        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
210        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
211        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
212
2132001-04-16      Joel Sherrill <joel@OARcorp.com>
214
215        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
216        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
217        as he debugged this BSP using a logic analyzer.  In particular,
218        there was a mistake where the index not offset of registers was
219        in the header file and the baud rate calculation was incorrect.
220
2212001-03-13      Joel Sherrill <joel@OARcorp.com>
222
223        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
224        directories.
225        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
226        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,

232        New files.
233        * Makefile.am, configure.in, shared/interrupts/Makefile.am,
234        shared/interrupts/maxvectors.c: Added support for mongoosev.
235        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
236
2372001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
238
239        * shared/cache/Makefile.am, tx39/include/Makefile.am:
240        Apply include_*HEADERS instead of H_FILES.
241
2422001-01-08      Joel Sherrill <joel@OARcorp.com>
243
244        * Added r46xx directory.
245        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
246        * shared/interrupts/installisrentries.c: Fixed typo.
247        * r46xx/.cvsignore, r46xx/Makefile.am,
248        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
249        r46xx/vectorisrs/vectorisrs.c: New files.
250
2512000-12-19      Joel Sherrill <joel@OARcorp.com>
252
253        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
254        vector handler.  This should be in a separate file so the BSP can
255        easily override it.
256
2572000-12-13      Joel Sherrill <joel@OARcorp.com>
258
259        * configure.in: Added new directories.
260        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
261        when compiling for a TX3904.
262        * shared/interrupts/maxvectors.c: Corrected conditional logic.
263        * tx39/Makefile.am: Added vectorisrs.
264        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
265        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
266        interrupt pending information on the TX3904 and vectors
267        an interrupt.
268
2692000-12-13      Joel Sherrill <joel@OARcorp.com>
270
271        * shared/.cvsignore, shared/Makefile.am,
272        shared/cache/.cvsignore, shared/cache/Makefile.am,
273        shared/cache/cache.c, shared/cache/cache_.h,
274        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
275        shared/interrupts/installisrentries.c,
276        shared/interrupts/isr_entries.S,
277        shared/interrupts/maxvectors.c, tx39/.cvsignore,
278        tx39/Makefile.am, tx39/include/.cvsignore,
279        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
280        Moved some pieces of interrupt processing from score/cpu to
281        libcpu/mips since many interrupt servicing characteristics are
282        CPU model dependent.  This patch addresses the number of interrupt
283        sources and where the ISR prologues are located.  The only way to
284        currently install the ISR prologues requires that the prologues
285        be installed into RAM.
286
2872000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
288
289        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
290
2912000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
292
293        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
294
2952000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
296
297        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
298        Switch to GNU canonicalization.
299
3002000-10-24      Alan Cudmore <alanc@linuxstart.com> and
301        Joel Sherrill <joel@OARcorp.com>
302
303        * This is a major reworking of the mips64orion port to use
304        gcc predefines as much as possible and a big push to multilib
305        the mips port.  The mips64orion port was copied/renamed to mips
306        to be more like other GNU tools.  Alan did most of the technical
307        work of determining how to map old macro names used by the mips64orion
308        port to standard compiler macro definitions.  Joel did the merge
309        with CVS magic to keep individual file history and did the BSP
310        modifications. Details follow:
311        * Makefile.am: Made clock and timer subdirectories conditional.
312        * configure.in: Ditto.
313        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
314        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
315
3162000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
317
318        * clock/Makefile.am, timer/Makefile.am: Include compile.am
319
3202000-08-10      Joel Sherrill <joel@OARcorp.com>
321
322        * ChangeLog: New file.
