23
24        * shared/interrupts/installisrentries.c: Added support for debug
25        exception vector.
26        * shared/interrupts/isr_entries.S: Added support for debug exception

30
31        * mongoosev/include/mongoose-v.h: Added cache constants.
32        * mongoosev/vectorisrs/vectorisrs.c: More tinkering to improve
33        performance.
34

36
37        * mongoosev/vectorisrs/vectorisrs.c: Fixed to use new frame format.
38
392001-02-05      Joel Sherrill <joel@OARcorp.com>
40
41        * isr_entries.S: Removed comment incorrectly indicating this
42        file was cpu_asm.S.
43        * vectorexceptions.c (mips_dump_exception_frame): New routine
44        broken out from default exception handler.
45
462001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
47
48        * mongoosev/vectorisrs/vectorisrs.c,
49        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
50        bspIo.h.
51
522001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
53
54        * Lots of tinkering and tuning as part of improving interrupt latency
55        and improving the per-task interrupt level control and FP mask handling.
56        With these modifications interrupt latency was measured at a worst-case
57        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
58        RTEMS tasks in the application.
59        * mongoosev/README: Updated. 
60        * mongoosev/include/mongoose-v.h: Masks modified.
61        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
62        software prioritization of interrupts.  If a higher priority interrupt
63        occurs while we are looking for new interrupts, we will reinitiate the
64        scan of all interrupts.
65        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
66        blank lines.
67
682002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

76
77        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
78        * configure.in: Remove.
79        * configure.ac: New file, generated from configure.in by autoupdate.
80
812001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

88
892000-05-24      Joel Sherrill <joel@OARcorp.com>
90
91        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
92        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
93        tx39/include/tx3904.h: All exceptions were given low numbers and thus
94        can be now be installed and processed in a uniform manner just like interrupts.
95        Variances between various MIPS ISA levels are not accounted for at this time.
96        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
97        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
98        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
99        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
100        shared maxvectors.c into a variety of CPU model specific versions to simplify
101        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
102        and created various CPU model versions.
103

110        * Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
111        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
112        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
113        shared/interrupts/maxvectors.c: Now works.  Significant rework
114        of exceptions and interrupt vectoring to clean things up.
115        * shared/interrupts/vectorexceptions.c: Removed.
116
1172001-05-07      Joel Sherrill <joel@OARcorp.com>
118
119        * shared/interrupts/vectorexceptions.c: New file to decode
120        exception code and vector appropriate NON-interrupt exception. 
121        * shared/interrupts/Makefile.am: Modified to reflect above.
122
1232001-04-20      Joel Sherrill <joel@OARcorp.com>
124
125        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
126        the other bits set in the Peripheral Function Interrupt Mask
127        Register when modifying those enabled for the DUART.
128        * mongoosev/include/mongoose-v.h (MONGOOSEV_ATOMIC_MASK,
129        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
130        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
131        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
132
1332001-04-16      Joel Sherrill <joel@OARcorp.com>
134
135        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
136        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
137        as he debugged this BSP using a logic analyzer.  In particular,
138        there was a mistake where the index not offset of registers was
139        in the header file and the baud rate calculation was incorrect.
140
1412001-03-13      Joel Sherrill <joel@OARcorp.com>
142
143        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
144        directories.
145        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
146        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,
147        mongoosev/duart/README.mguart, mongoosev/duart/mg5uart.c,
148        mongoosev/duart/mg5uart.h, mongoosev/duart/mg5uart_reg.c,
149        mongoosev/include/.cvsignore, mongoosev/include/Makefile.am,
150        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/.cvsignore,
151        mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/vectorisrs.c:
152        New files.
153        * Makefile.am, configure.in, shared/interrupts/Makefile.am,
154        shared/interrupts/maxvectors.c: Added support for mongoosev.
155        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
156
1572001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
158
159        * shared/cache/Makefile.am, tx39/include/Makefile.am:
160        Apply include_*HEADERS instead of H_FILES.
161
1622001-01-08      Joel Sherrill <joel@OARcorp.com>
163
164        * Added r46xx directory.
165        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
166        * shared/interrupts/installisrentries.c: Fixed typo.
167        * r46xx/.cvsignore, r46xx/Makefile.am,
168        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
169        r46xx/vectorisrs/vectorisrs.c: New files.
170
1712000-12-19      Joel Sherrill <joel@OARcorp.com>
172
173        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
174        vector handler.  This should be in a separate file so the BSP can
175        easily override it.
176
1772000-12-13      Joel Sherrill <joel@OARcorp.com>
178
179        * configure.in: Added new directories.
180        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
181        when compiling for a TX3904.
182        * shared/interrupts/maxvectors.c: Corrected conditional logic.
183        * tx39/Makefile.am: Added vectorisrs.
184        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
185        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
186        interrupt pending information on the TX3904 and vectors
187        an interrupt.
188
1892000-12-13      Joel Sherrill <joel@OARcorp.com>
190
191        * shared/.cvsignore, shared/Makefile.am,
192        shared/cache/.cvsignore, shared/cache/Makefile.am,
193        shared/cache/cache.c, shared/cache/cache_.h,
194        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
195        shared/interrupts/installisrentries.c,
196        shared/interrupts/isr_entries.S,
197        shared/interrupts/maxvectors.c, tx39/.cvsignore,
198        tx39/Makefile.am, tx39/include/.cvsignore,
199        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
200        Moved some pieces of interrupt processing from score/cpu to
201        libcpu/mips since many interrupt servicing characteristics are
202        CPU model dependent.  This patch addresses the number of interrupt
203        sources and where the ISR prologues are located.  The only way to
204        currently install the ISR prologues requires that the prologues
205        be installed into RAM.
206
2072000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
208
209        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
210
2112000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
212
213        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
214
2152000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
216
217        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
218        Switch to GNU canonicalization.
219
2202000-10-24      Alan Cudmore <alanc@linuxstart.com> and
221        Joel Sherrill <joel@OARcorp.com>
222
223        * This is a major reworking of the mips64orion port to use
224        gcc predefines as much as possible and a big push to multilib
225        the mips port.  The mips64orion port was copied/renamed to mips
226        to be more like other GNU tools.  Alan did most of the technical
227        work of determining how to map old macro names used by the mips64orion
228        port to standard compiler macro definitions.  Joel did the merge
229        with CVS magic to keep individual file history and did the BSP
230        modifications. Details follow:
231        * Makefile.am: Made clock and timer subdirectories conditional.
232        * configure.in: Ditto.
233        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
234        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
235
2362000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
237
238        * clock/Makefile.am, timer/Makefile.am: Include compile.am
239
2402000-08-10      Joel Sherrill <joel@OARcorp.com>
241
242        * ChangeLog: New file.
