2 | |
---|
3 | * mongoosev/vectorisrs/vectorisrs.c: Fixed to use new frame format. |
---|
4 | |
---|
5 | 2001-02-05 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. |
---|
11 | |
---|
12 | 2001-02-01 Greg Menke <gregory.menke@gsfc.nasa.gov> |
---|
13 | |
---|
14 | * mongoosev/vectorisrs/vectorisrs.c, |
---|
15 | shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just |
---|
16 | bspIo.h. |
---|
17 | |
---|
18 | 2001-02-01 Greg Menke <gregory.menke@gsfc.nasa.gov> |
---|
19 | |
---|
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. |
---|
33 | |
---|
34 | 2002-01-03 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 | |
---|
41 | 2001-10-11 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 | |
---|
47 | 2001-09-27 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 | |
---|
55 | 2000-05-24 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 | |
---|
70 | 2001-05-24 Greg Menke <gregory.menke@gsfc.nasa.gov> |
---|
71 | |
---|
72 | * clock/clock.S: Move placement of nop. |
---|
73 | |
---|
74 | 2001-05-22 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 | |
---|
83 | 2001-05-07 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 | |
---|
89 | 2001-04-20 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 | |

---|
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 | |
---|
107 | 2001-03-13 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, |
---|
117 | mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/vectorisrs.c: |
---|
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 | |
---|
123 | 2001-03-03 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 | |
---|
128 | 2001-01-08 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 | |
---|
137 | 2000-12-19 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 | |
---|
143 | 2000-12-13 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 | |
---|
155 | 2000-12-13 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 | |
---|
173 | 2000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de> |
---|
174 | |
---|
175 | * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS. |
---|
176 | |
---|
177 | 2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de> |
---|
178 | |
---|
179 | * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal. |
---|
180 | |
---|
181 | 2000-10-26 Ralf Corsepius <corsepiu@faw.uni-ulm.de> |
---|
182 | |
---|
183 | * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. |
---|
184 | Switch to GNU canonicalization. |
---|
185 | |
---|
186 | 2000-10-24 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 | |
---|
202 | 2000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de> |
---|
203 | |
---|
204 | * clock/Makefile.am, timer/Makefile.am: Include compile.am |
---|
205 | |
---|
206 | 2000-08-10 Joel Sherrill <joel@OARcorp.com> |
---|
207 | |
---|
208 | * ChangeLog: New file. |
