52001-02-05      Joel Sherrill <joel@OARcorp.com>
6
7        * isr_entries.S: Removed comment incorrectly indicating this
8        file was cpu_asm.S.
9        * vectorexceptions.c (mips_dump_exception_frame): New routine
10        broken out from default exception handler.

13
14        * mongoosev/vectorisrs/vectorisrs.c,
15        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
16        bspIo.h.

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

342002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
35
36        * mongoosev/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
37        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
38        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
39        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
40
412001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
42
43        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
44        * configure.in: Remove.
45        * configure.ac: New file, generated from configure.in by autoupdate.
46
472001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
48
49        * tx39/include/Makefile.am: Use 'TMPINSTALL_FILES ='.
50        * mongoosev/include/Makefile.am: Use 'TMPINSTALL_FILES ='.
51        * mongoosev/duart/Makefile.am: Use 'PREINSTALL_FILES ='.
52        * shared/cache/Makefile.am: Use 'PREINSTALL_FILES ='.
53        * shared/cache/Makefile.am: Use 'CLEANFILES ='.
54
552000-05-24      Joel Sherrill <joel@OARcorp.com>
56
57        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
58        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
59        tx39/include/tx3904.h: All exceptions were given low numbers and thus
60        can be now be installed and processed in a uniform manner just like interrupts.
61        Variances between various MIPS ISA levels are not accounted for at this time.
62        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
63        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
64        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
65        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
66        shared maxvectors.c into a variety of CPU model specific versions to simplify
67        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
68        and created various CPU model versions.
69
702001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>
71
72        * clock/clock.S: Move placement of nop.
73
742001-05-22      Greg Menke <gregory.menke@gsfc.nasa.gov>
75
76        * Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
77        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
78        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
79        shared/interrupts/maxvectors.c: Now works.  Significant rework
80        of exceptions and interrupt vectoring to clean things up.
81        * shared/interrupts/vectorexceptions.c: Removed.
82
832001-05-07      Joel Sherrill <joel@OARcorp.com>
84
85        * shared/interrupts/vectorexceptions.c: New file to decode
86        exception code and vector appropriate NON-interrupt exception. 
87        * shared/interrupts/Makefile.am: Modified to reflect above.
88
892001-04-20      Joel Sherrill <joel@OARcorp.com>
90
91        * mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
92        the other bits set in the Peripheral Function Interrupt Mask
93        Register when modifying those enabled for the DUART.
94        * mongoosev/include/mongoose-v.h (MONGOOSEV_ATOMIC_MASK,
95        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
96        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
97        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
98
992001-04-16      Joel Sherrill <joel@OARcorp.com>
100
101        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
102        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
103        as he debugged this BSP using a logic analyzer.  In particular,
104        there was a mistake where the index not offset of registers was
105        in the header file and the baud rate calculation was incorrect.
106
1072001-03-13      Joel Sherrill <joel@OARcorp.com>
108
109        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
110        directories.
111        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
112        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,
113        mongoosev/duart/README.mguart, mongoosev/duart/mg5uart.c,
114        mongoosev/duart/mg5uart.h, mongoosev/duart/mg5uart_reg.c,
115        mongoosev/include/.cvsignore, mongoosev/include/Makefile.am,
116        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/.cvsignore,

118        New files.
119        * Makefile.am, configure.in, shared/interrupts/Makefile.am,
120        shared/interrupts/maxvectors.c: Added support for mongoosev.
121        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
122
1232001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
124
125        * shared/cache/Makefile.am, tx39/include/Makefile.am:
126        Apply include_*HEADERS instead of H_FILES.
127
1282001-01-08      Joel Sherrill <joel@OARcorp.com>
129
130        * Added r46xx directory.
131        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
132        * shared/interrupts/installisrentries.c: Fixed typo.
133        * r46xx/.cvsignore, r46xx/Makefile.am,
134        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
135        r46xx/vectorisrs/vectorisrs.c: New files.
136
1372000-12-19      Joel Sherrill <joel@OARcorp.com>
138
139        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
140        vector handler.  This should be in a separate file so the BSP can
141        easily override it.
142
1432000-12-13      Joel Sherrill <joel@OARcorp.com>
144
145        * configure.in: Added new directories.
146        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
147        when compiling for a TX3904.
148        * shared/interrupts/maxvectors.c: Corrected conditional logic.
149        * tx39/Makefile.am: Added vectorisrs.
150        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
151        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
152        interrupt pending information on the TX3904 and vectors
153        an interrupt.
154
1552000-12-13      Joel Sherrill <joel@OARcorp.com>
156
157        * shared/.cvsignore, shared/Makefile.am,
158        shared/cache/.cvsignore, shared/cache/Makefile.am,
159        shared/cache/cache.c, shared/cache/cache_.h,
160        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
161        shared/interrupts/installisrentries.c,
162        shared/interrupts/isr_entries.S,
163        shared/interrupts/maxvectors.c, tx39/.cvsignore,
164        tx39/Makefile.am, tx39/include/.cvsignore,
165        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
166        Moved some pieces of interrupt processing from score/cpu to
167        libcpu/mips since many interrupt servicing characteristics are
168        CPU model dependent.  This patch addresses the number of interrupt
169        sources and where the ISR prologues are located.  The only way to
170        currently install the ISR prologues requires that the prologues
171        be installed into RAM.
172
1732000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
174
175        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
176
1772000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
178
179        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
180
1812000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
182
183        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
184        Switch to GNU canonicalization.
185
1862000-10-24      Alan Cudmore <alanc@linuxstart.com> and
187        Joel Sherrill <joel@OARcorp.com>
188
189        * This is a major reworking of the mips64orion port to use
190        gcc predefines as much as possible and a big push to multilib
191        the mips port.  The mips64orion port was copied/renamed to mips
192        to be more like other GNU tools.  Alan did most of the technical
193        work of determining how to map old macro names used by the mips64orion
194        port to standard compiler macro definitions.  Joel did the merge
195        with CVS magic to keep individual file history and did the BSP
196        modifications. Details follow:
197        * Makefile.am: Made clock and timer subdirectories conditional.
198        * configure.in: Ditto.
199        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
200        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
201
2022000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
203
204        * clock/Makefile.am, timer/Makefile.am: Include compile.am
205

207
208        * ChangeLog: New file.
