93
94        * mongoosev/vectorisrs/vectorisrs.c,
95        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
96        bspIo.h.
97
982001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
99
100        * Lots of tinkering and tuning as part of improving interrupt latency
101        and improving the per-task interrupt level control and FP mask handling.
102        With these modifications interrupt latency was measured at a worst-case
103        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
104        RTEMS tasks in the application.

106        * mongoosev/include/mongoose-v.h: Masks modified.
107        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
108        software prioritization of interrupts.  If a higher priority interrupt
109        occurs while we are looking for new interrupts, we will reinitiate the
110        scan of all interrupts.
111        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
112        blank lines.
113
1142002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
115

117        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
118        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
119        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
120
1212001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
122
123        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
124        * configure.in: Remove.
125        * configure.ac: New file, generated from configure.in by autoupdate.
126
1272001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

132        * shared/cache/Makefile.am: Use 'PREINSTALL_FILES ='.
133        * shared/cache/Makefile.am: Use 'CLEANFILES ='.
134
1352000-05-24      Joel Sherrill <joel@OARcorp.com>
136
137        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
138        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
139        tx39/include/tx3904.h: All exceptions were given low numbers and thus
140        can be now be installed and processed in a uniform manner just like interrupts.
141        Variances between various MIPS ISA levels are not accounted for at this time.
142        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
143        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
144        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
145        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
146        shared maxvectors.c into a variety of CPU model specific versions to simplify
147        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
148        and created various CPU model versions.
149

151
152        * clock/clock.S: Move placement of nop.

157        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
158        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
159        shared/interrupts/maxvectors.c: Now works.  Significant rework
160        of exceptions and interrupt vectoring to clean things up.
161        * shared/interrupts/vectorexceptions.c: Removed.
162
1632001-05-07      Joel Sherrill <joel@OARcorp.com>
164
165        * shared/interrupts/vectorexceptions.c: New file to decode
166        exception code and vector appropriate NON-interrupt exception. 
167        * shared/interrupts/Makefile.am: Modified to reflect above.
168
1692001-04-20      Joel Sherrill <joel@OARcorp.com>
170
171        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
172        the other bits set in the Peripheral Function Interrupt Mask
173        Register when modifying those enabled for the DUART.

175        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
176        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
177        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
178
1792001-04-16      Joel Sherrill <joel@OARcorp.com>
180
181        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
182        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
183        as he debugged this BSP using a logic analyzer.  In particular,
184        there was a mistake where the index not offset of registers was
185        in the header file and the baud rate calculation was incorrect.
186
1872001-03-13      Joel Sherrill <joel@OARcorp.com>
188
189        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
190        directories.
191        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
192        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,

200        shared/interrupts/maxvectors.c: Added support for mongoosev.
201        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
202
2032001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
204
205        * shared/cache/Makefile.am, tx39/include/Makefile.am:
206        Apply include_*HEADERS instead of H_FILES.
207
2082001-01-08      Joel Sherrill <joel@OARcorp.com>
209
210        * Added r46xx directory.
211        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
212        * shared/interrupts/installisrentries.c: Fixed typo.
213        * r46xx/.cvsignore, r46xx/Makefile.am,
214        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
215        r46xx/vectorisrs/vectorisrs.c: New files.
216
2172000-12-19      Joel Sherrill <joel@OARcorp.com>
218
219        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
220        vector handler.  This should be in a separate file so the BSP can
221        easily override it.
222
2232000-12-13      Joel Sherrill <joel@OARcorp.com>
224
225        * configure.in: Added new directories.
226        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
227        when compiling for a TX3904.
228        * shared/interrupts/maxvectors.c: Corrected conditional logic.
229        * tx39/Makefile.am: Added vectorisrs.
230        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
231        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
232        interrupt pending information on the TX3904 and vectors
233        an interrupt.
234
2352000-12-13      Joel Sherrill <joel@OARcorp.com>
236
237        * shared/.cvsignore, shared/Makefile.am,
238        shared/cache/.cvsignore, shared/cache/Makefile.am,
239        shared/cache/cache.c, shared/cache/cache_.h,
240        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
241        shared/interrupts/installisrentries.c,
242        shared/interrupts/isr_entries.S,
243        shared/interrupts/maxvectors.c, tx39/.cvsignore,
244        tx39/Makefile.am, tx39/include/.cvsignore,
245        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
246        Moved some pieces of interrupt processing from score/cpu to
247        libcpu/mips since many interrupt servicing characteristics are
248        CPU model dependent.  This patch addresses the number of interrupt
249        sources and where the ISR prologues are located.  The only way to
250        currently install the ISR prologues requires that the prologues
251        be installed into RAM.
252
2532000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
254
255        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
256
2572000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
258
259        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
260
2612000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
262
263        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
264        Switch to GNU canonicalization.
265
2662000-10-24      Alan Cudmore <alanc@linuxstart.com> and
267        Joel Sherrill <joel@OARcorp.com>
268
269        * This is a major reworking of the mips64orion port to use
270        gcc predefines as much as possible and a big push to multilib
271        the mips port.  The mips64orion port was copied/renamed to mips
272        to be more like other GNU tools.  Alan did most of the technical
273        work of determining how to map old macro names used by the mips64orion
274        port to standard compiler macro definitions.  Joel did the merge
275        with CVS magic to keep individual file history and did the BSP
276        modifications. Details follow:
277        * Makefile.am: Made clock and timer subdirectories conditional.
278        * configure.in: Ditto.
279        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
280        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
281
2822000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
283
284        * clock/Makefile.am, timer/Makefile.am: Include compile.am
285
2862000-08-10      Joel Sherrill <joel@OARcorp.com>
287
288        * ChangeLog: New file.
