3        * mongoosev/include/mongoose-v.h: Added cache constants.
4        * mongoosev/vectorisrs/vectorisrs.c: More tinkering to improve
5        performance.

72002-02-08      Joel Sherrill <joel@OARcorp.com>
8
9        * mongoosev/vectorisrs/vectorisrs.c: Fixed to use new frame format.
10
112001-02-05      Joel Sherrill <joel@OARcorp.com>
12
13        * isr_entries.S: Removed comment incorrectly indicating this
14        file was cpu_asm.S.
15        * vectorexceptions.c (mips_dump_exception_frame): New routine
16        broken out from default exception handler.
17
182001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
19
20        * mongoosev/vectorisrs/vectorisrs.c,
21        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
22        bspIo.h.
23

25
26        * Lots of tinkering and tuning as part of improving interrupt latency
27        and improving the per-task interrupt level control and FP mask handling.
28        With these modifications interrupt latency was measured at a worst-case
29        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
30        RTEMS tasks in the application.
31        * mongoosev/README: Updated. 
32        * mongoosev/include/mongoose-v.h: Masks modified.
33        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
34        software prioritization of interrupts.  If a higher priority interrupt
35        occurs while we are looking for new interrupts, we will reinitiate the
36        scan of all interrupts.
37        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
38        blank lines.

41
42        * mongoosev/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
43        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
44        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
45        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.

48
49        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
50        * configure.in: Remove.
51        * configure.ac: New file, generated from configure.in by autoupdate.
52
532001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

612000-05-24      Joel Sherrill <joel@OARcorp.com>
62
63        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
64        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
65        tx39/include/tx3904.h: All exceptions were given low numbers and thus
66        can be now be installed and processed in a uniform manner just like interrupts.
67        Variances between various MIPS ISA levels are not accounted for at this time.
68        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
69        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
70        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
71        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
72        shared maxvectors.c into a variety of CPU model specific versions to simplify
73        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
74        and created various CPU model versions.
75
762001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>
77
78        * clock/clock.S: Move placement of nop.
79
802001-05-22      Greg Menke <gregory.menke@gsfc.nasa.gov>
81
82        * Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
83        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
84        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
85        shared/interrupts/maxvectors.c: Now works.  Significant rework
86        of exceptions and interrupt vectoring to clean things up.
87        * shared/interrupts/vectorexceptions.c: Removed.
88
892001-05-07      Joel Sherrill <joel@OARcorp.com>
90
91        * shared/interrupts/vectorexceptions.c: New file to decode
92        exception code and vector appropriate NON-interrupt exception. 
93        * shared/interrupts/Makefile.am: Modified to reflect above.
94
952001-04-20      Joel Sherrill <joel@OARcorp.com>
96
97        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
98        the other bits set in the Peripheral Function Interrupt Mask
99        Register when modifying those enabled for the DUART.
100        * mongoosev/include/mongoose-v.h (MONGOOSEV_ATOMIC_MASK,
101        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
102        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
103        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
104
1052001-04-16      Joel Sherrill <joel@OARcorp.com>
106
107        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
108        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
109        as he debugged this BSP using a logic analyzer.  In particular,
110        there was a mistake where the index not offset of registers was
111        in the header file and the baud rate calculation was incorrect.
112
1132001-03-13      Joel Sherrill <joel@OARcorp.com>
114
115        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
116        directories.
117        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
118        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,
119        mongoosev/duart/README.mguart, mongoosev/duart/mg5uart.c,
120        mongoosev/duart/mg5uart.h, mongoosev/duart/mg5uart_reg.c,
121        mongoosev/include/.cvsignore, mongoosev/include/Makefile.am,

130
131        * shared/cache/Makefile.am, tx39/include/Makefile.am:
132        Apply include_*HEADERS instead of H_FILES.
133
1342001-01-08      Joel Sherrill <joel@OARcorp.com>
135
136        * Added r46xx directory.
137        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
138        * shared/interrupts/installisrentries.c: Fixed typo.
139        * r46xx/.cvsignore, r46xx/Makefile.am,
140        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
141        r46xx/vectorisrs/vectorisrs.c: New files.
142
1432000-12-19      Joel Sherrill <joel@OARcorp.com>
144
145        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
146        vector handler.  This should be in a separate file so the BSP can
147        easily override it.
148
1492000-12-13      Joel Sherrill <joel@OARcorp.com>
150
151        * configure.in: Added new directories.
152        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
153        when compiling for a TX3904.
154        * shared/interrupts/maxvectors.c: Corrected conditional logic.
155        * tx39/Makefile.am: Added vectorisrs.
156        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
157        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
158        interrupt pending information on the TX3904 and vectors
159        an interrupt.
160
1612000-12-13      Joel Sherrill <joel@OARcorp.com>
162
163        * shared/.cvsignore, shared/Makefile.am,
164        shared/cache/.cvsignore, shared/cache/Makefile.am,
165        shared/cache/cache.c, shared/cache/cache_.h,
166        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
167        shared/interrupts/installisrentries.c,
168        shared/interrupts/isr_entries.S,
169        shared/interrupts/maxvectors.c, tx39/.cvsignore,
170        tx39/Makefile.am, tx39/include/.cvsignore,
171        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
172        Moved some pieces of interrupt processing from score/cpu to
173        libcpu/mips since many interrupt servicing characteristics are
174        CPU model dependent.  This patch addresses the number of interrupt
175        sources and where the ISR prologues are located.  The only way to
176        currently install the ISR prologues requires that the prologues
177        be installed into RAM.
178
1792000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
180
181        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
182
1832000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
184
185        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
186
1872000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
188
189        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
190        Switch to GNU canonicalization.
191
1922000-10-24      Alan Cudmore <alanc@linuxstart.com> and
193        Joel Sherrill <joel@OARcorp.com>
194
195        * This is a major reworking of the mips64orion port to use
196        gcc predefines as much as possible and a big push to multilib
197        the mips port.  The mips64orion port was copied/renamed to mips
198        to be more like other GNU tools.  Alan did most of the technical
199        work of determining how to map old macro names used by the mips64orion
200        port to standard compiler macro definitions.  Joel did the merge
201        with CVS magic to keep individual file history and did the BSP
202        modifications. Details follow:
203        * Makefile.am: Made clock and timer subdirectories conditional.
204        * configure.in: Ditto.
205        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
206        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
207
2082000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
209
210        * clock/Makefile.am, timer/Makefile.am: Include compile.am
211
