97
98        * mongoosev/vectorisrs/vectorisrs.c,
99        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
100        bspIo.h.
101
1022001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
103
104        * Lots of tinkering and tuning as part of improving interrupt latency
105        and improving the per-task interrupt level control and FP mask handling.
106        With these modifications interrupt latency was measured at a worst-case
107        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
108        RTEMS tasks in the application.
109        * mongoosev/README: Updated. 
110        * mongoosev/include/mongoose-v.h: Masks modified.
111        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
112        software prioritization of interrupts.  If a higher priority interrupt
113        occurs while we are looking for new interrupts, we will reinitiate the
114        scan of all interrupts.
115        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
116        blank lines.
117
1182002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
119

121        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
122        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
123        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
124
1252001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
126
127        * .cvsignore: Add autom4te.cache for autoconf > 2.52.

136        * shared/cache/Makefile.am: Use 'PREINSTALL_FILES ='.
137        * shared/cache/Makefile.am: Use 'CLEANFILES ='.
138
1392000-05-24      Joel Sherrill <joel@OARcorp.com>
140
141        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
142        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
143        tx39/include/tx3904.h: All exceptions were given low numbers and thus
144        can be now be installed and processed in a uniform manner just like interrupts.
145        Variances between various MIPS ISA levels are not accounted for at this time.
146        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
147        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
148        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
149        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
150        shared maxvectors.c into a variety of CPU model specific versions to simplify
151        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
152        and created various CPU model versions.
153
1542001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>
155
156        * clock/clock.S: Move placement of nop.

161        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
162        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
163        shared/interrupts/maxvectors.c: Now works.  Significant rework
164        of exceptions and interrupt vectoring to clean things up.
165        * shared/interrupts/vectorexceptions.c: Removed.
166
1672001-05-07      Joel Sherrill <joel@OARcorp.com>
168
169        * shared/interrupts/vectorexceptions.c: New file to decode
170        exception code and vector appropriate NON-interrupt exception. 
171        * shared/interrupts/Makefile.am: Modified to reflect above.
172
1732001-04-20      Joel Sherrill <joel@OARcorp.com>
174
175        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
176        the other bits set in the Peripheral Function Interrupt Mask
177        Register when modifying those enabled for the DUART.

179        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
180        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
181        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
182
1832001-04-16      Joel Sherrill <joel@OARcorp.com>
184
185        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
186        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
187        as he debugged this BSP using a logic analyzer.  In particular,
188        there was a mistake where the index not offset of registers was
189        in the header file and the baud rate calculation was incorrect.
190
1912001-03-13      Joel Sherrill <joel@OARcorp.com>
192
193        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
194        directories.
195        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,

205        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
206
2072001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
208
209        * shared/cache/Makefile.am, tx39/include/Makefile.am:
210        Apply include_*HEADERS instead of H_FILES.
211
2122001-01-08      Joel Sherrill <joel@OARcorp.com>
213
214        * Added r46xx directory.
215        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
216        * shared/interrupts/installisrentries.c: Fixed typo.
217        * r46xx/.cvsignore, r46xx/Makefile.am,
218        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
219        r46xx/vectorisrs/vectorisrs.c: New files.
220
2212000-12-19      Joel Sherrill <joel@OARcorp.com>
222
223        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
224        vector handler.  This should be in a separate file so the BSP can
225        easily override it.
226
2272000-12-13      Joel Sherrill <joel@OARcorp.com>
228
229        * configure.in: Added new directories.
230        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
231        when compiling for a TX3904.
232        * shared/interrupts/maxvectors.c: Corrected conditional logic.
233        * tx39/Makefile.am: Added vectorisrs.
234        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
235        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
236        interrupt pending information on the TX3904 and vectors
237        an interrupt.
238
2392000-12-13      Joel Sherrill <joel@OARcorp.com>
240
241        * shared/.cvsignore, shared/Makefile.am,
242        shared/cache/.cvsignore, shared/cache/Makefile.am,
243        shared/cache/cache.c, shared/cache/cache_.h,
244        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
245        shared/interrupts/installisrentries.c,
246        shared/interrupts/isr_entries.S,
247        shared/interrupts/maxvectors.c, tx39/.cvsignore,
248        tx39/Makefile.am, tx39/include/.cvsignore,
249        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
250        Moved some pieces of interrupt processing from score/cpu to
251        libcpu/mips since many interrupt servicing characteristics are
252        CPU model dependent.  This patch addresses the number of interrupt
253        sources and where the ISR prologues are located.  The only way to
254        currently install the ISR prologues requires that the prologues
255        be installed into RAM.
256
2572000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
258
259        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
260
2612000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
262
263        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
264
2652000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
266
267        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
268        Switch to GNU canonicalization.
269
2702000-10-24      Alan Cudmore <alanc@linuxstart.com> and
271        Joel Sherrill <joel@OARcorp.com>
272
273        * This is a major reworking of the mips64orion port to use
274        gcc predefines as much as possible and a big push to multilib
275        the mips port.  The mips64orion port was copied/renamed to mips
276        to be more like other GNU tools.  Alan did most of the technical
277        work of determining how to map old macro names used by the mips64orion
278        port to standard compiler macro definitions.  Joel did the merge
279        with CVS magic to keep individual file history and did the BSP
280        modifications. Details follow:
281        * Makefile.am: Made clock and timer subdirectories conditional.
282        * configure.in: Ditto.
283        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
284        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
285
2862000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
287
288        * clock/Makefile.am, timer/Makefile.am: Include compile.am
289
2902000-08-10      Joel Sherrill <joel@OARcorp.com>
291
292        * ChangeLog: New file.
