2003-04-10  Nick Garnett  
2
 
3
        * src/i386.ld:
4
        Added libsupc++.a to GROUP() directive for GCC versions later than
5
        3.0.
6
 
7
2003-01-31  Mark Salter  
8
 
9
        * src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
10
        handle exit.
11
 
12
2002-11-28  Nick Garnett  
13
 
14
        * src/vectors.S: Added GRUB startup option to tests for IDT
15
        initialization. Added call to breakpoint() before cyg_start(),
16
        controlled by CYGDBG_HAL_DEBUG_GDB_INITIAL_BREAK.
17
 
18
2002-05-17  Nick Garnett  
19
 
20
        * src/vectors.S: Rearranged interrupt stack definitions to make it
21
        work correctly in SMP case. The #ifdefs were improperly nested.
22
 
23
2002-04-29  Jonathan Larmour  
24
 
25
        * src/vectors.S:
26
        Don't use .file as it can confuse debugging since the .file
27
        doesn't contain the path and therefore the debugger will never
28
        know where it lives! This conflicts with using -Wa,--gstabs.
29
 
30
2002-04-15  Jonathan Larmour  
31
 
32
        * src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
33
        __do_syscall.
34
 
35
2002-01-08  Nick Garnett  
36
 
37
        * include/hal_arch.h:
38
        Removed consideration of lazy FPU context switching in determining
39
        the size of CYGNUM_HAL_STACK_CONTEXT_SIZE, since it does not
40
        actually make any difference - and previously resulted in too
41
        small a value for CYGNUM_HAL_STACK_SIZE_MINIMUM.
42
 
43
2002-01-07  Nick Garnett  
44
 
45
        * src/vectors.S (__fpu_switch_vsr): Fixed register usage bug.
46
 
47
2001-12-19  Mark Salter  
48
 
49
        * include/arch.inc: Use fnsave instead of fsave.
50
        * src/vectors.S: Ditto.
51
 
52
2001-12-11  Nick Garnett  
53
 
54
        * src/i386.ld (SECTION_rel__got): Added entry for
55
        .rel.gnu.linkonce* that more recent versions of the compiler seem
56
        to generate.
57
 
58
2001-12-07  Jonathan Larmour  
59
 
60
        * src/i386.ld: Add missing close bracket.
61
 
62
2001-12-06  Jonathan Larmour  
63
 
64
        * src/i386.ld: Add .rel.text and .rel.data sections to avoid
65
        linker warnings, which can cause the linker to then get confused.
66
        (From nickc)
67
 
68
2001-11-21  Mark Salter  
69
 
70
        * src/i386_stub.c (__do_read_msr): Add mem_fault handling.
71
        (__do_write_msr): Ditto.
72
 
73
2001-10-19  Ian Campbell  
74
 
75
        * include/hal_cache.h: Provide HAL_DCACHE_IS_ENABLED and
76
        HAL_ICACHE_IS_ENABLED macros.
77
 
78
2001-10-15  Mark Salter  
79
 
80
        * src/i386_stub.c (hal_get_gdb_registers): Save idt/gdt in GDB regs.
81
        ({put,get}_register_as_bytes): Support idt/gdt.
82
 
83
2001-10-12  Mark Salter  
84
 
85
        * include/i386_stub.h: Add support for FPU and other regs.
86
        * src/i386_stub.c: Ditto.
87
 
88
        * src/vectors.S: Add SSE support.

93
        CYGHWR_HAL_I386_PENTIUM_SSE.
94
        * cdl/hal_i386.cdl: Add CYGHWR_HAL_I386_PENTIUM_GDB_REGS.
95
 
96
2001-10-08  Ian Campbell  
97
 
98
        * cdl/hal_i386.cdl: move CYGBLD_BUILD_I386_ROMBOOT and
99
        CYGBLD_BUILD_REDBOOT_BIN_ROM to pc package.
100
        * src/romboot.S: Moved to pc package
101
        * src/romboot.ld: Moved to pc package
102
 
103
2001-10-11  Fabrice Gautier  
104
 
105
        * include/hal_io.h: Add _STRING variants of I/O macros to allow
106
        writing of consecutive items to the same registers.
107
 
108
2001-10-10  Fabrice Gautier  
109
2001-10-10  Jonathan Larmour  
110
 
111
        * src/vectors.S: Don't use apostrophes in comments as it can confuse
112
        preprocessors sometimes.
113
 
114
2001-10-05  Mark Salter  
115
 
116
        * src/vectors.S: Support separate stub stack.
117
        (__syscall_tramp): Trampoline for GNUPRo syscalls (int $0x80).
118
 
119
        * src/i386_stub.c (__is_bsp_syscall): New function.
120
 
121
        * src/hal_misc.c (cyg_hal_exception_handler): Add mem fault handling.
122
 
123
        * cdl/hal_i386.cdl: Add hal_syscalls.c to compile list.
124
 
125
        * src/hal_syscall.c: New file. Support GNUPro syscalls.
126
 
127
2001-10-01  Ian Campbell  
128
 
129
        * src/vectors.S: include CYGBLD_HAL_PLATFORM_H rather than
130
        
131
 
132
2001-09-05  Jonathan Larmour  
133
 
134
        * src/vectors.S (__default_interrupt_vsr): Adjust saved stack pointer
135
        for the hardware and trampoline saved data.
136
        (__default_exception_vsr): Ditto.
137
 
138
2001-08-31  Nick Garnett  
139
 
140
        * include/arch.inc: Clean up typo in stack switching macros.
141
 
142
2001-08-22  Nick Garnett  
143
 
144
        * include/hal_io.h: Added some macros to do in-memory data
145
        accesses for memory mapped devices.
146
 
147
        * include/hal_arch.h: Attempted to make some sense out of the
148
        stack size macros.
149
 
150
        * include/hal_intr.h: Extended VSR table to its full 256 entries.
151
 
152
        * src/vectors.S: Lots of changes to incorporate SMP support.
153
 
154
        * src/i386.ld: Added SMP related data, that must be shared between
155
        RedBoot and applications, for example.
156
 
157
        * include/hal_smp.h: Added this file to define SMP related HAL
158
        interfaces.
159
 
160
        * include/arch.inc: Added SMP support. This includes explicit SMP
161
        macros and stack-switching macros that have single CPU and SMP
162
        variants. Some SMP modifications to the lazy FPU switching code
163
        leave it functional in the single CPU case, but do not yet work in
164
        the SMP case. Lazy FPU switching is currently disabled for SMP in
165
        the CDL.
166
 
167
        * cdl/hal_i386.cdl: Added SMP configury.
168
 
169
2001-07-31  Jonathan Larmour  
170
 
171
        * src/hal_misc.c: Fix "implicit decl of diag_printf" warning.
172
 
173
2001-07-13  Nick Garnett  
174
 
175
        * include/arch.inc:
176
        Added code to clear CR0:TS bit in hal_fpu_init macro. If this bit
177
        is not clear, then the following finit might trap, and we don't
178
        want that.
179
        Added a compare to hal_fpu_push_exc macro for a zero fpu state
180
        owner. The code was assuming the move set the condition codes,
181
        which it doesn't.
182
 
183
2001-07-08  Jonathan Larmour  
184
 
185
        * include/hal_arch.h (HAL_THREAD_INIT_FPU_CONTEXT): Fix indirection to
186
        fpucontext members.
187
 
188
2001-07-05  Jonathan Larmour  
189
 
190
        * include/hal_intr.h (HAL_RESTORE_INTERRUPTS): Don't change name
191
        for clobbers.
192
 
193
2001-07-04  Jonathan Larmour  
194
 
195
        * include/hal_intr.h: Be pedantic about register constraint syntax
196
        to satisfy newer compilers
197
        * include/hal_io.h: Ditto
198
 
199
2001-06-13  Jonathan Larmour  
200
 
201
        * cdl/hal_i386.cdl: Default to enabling FPU support since gcc assumes
202
        a hardware FPU anyway. Also default to lazy FPU switching since
203
        this is cheapest in the modal case.
204
 
205
2001-05-01  Nick Garnett  
206
 
207
        [x86 branch]
208
        * src/context.S: Fixed bug in hal_setjmp() that corrupted EBX.
209
 
210
2001-04-26  Nick Garnett  
211
 
212
        [x86 branch]
213
        * include/hal_intr.h:
214
        Tidied up mapping of exceptions to vectors. Added implementation
215
        of HAL_VSR_SET_TO_ECOS_HANDLER().
216
 
217
2001-04-19  Nick Garnett  
218
 
219
        [x86 branch]
220
        * src/vectors.S (__default_exception_vsr):
221
        Disabled ROM monitor stack switching here. There are problems with
222
        this that I do not have time to worry about now.
223
 
224
2001-03-30  Nick Garnett  
225
 
226
        [x86 branch]
227
        * src/romboot.S: Added code to call video BIOS to initialize
228
        display.
229
 
230
        * src/vectors.S: Added code to copy data section from ROM to RAM
231
        in ROM booted systems.
232
 
233
2001-03-16  Nick Garnett  
234
 
235
        [x86 branch]
236
        * src/romboot.S:
237
        * src/romboot.ld:
238
        Added these files to build 256 byte realmode bootstrap at the top
239
        of ROM.
240
        (This is work in progress and is not yet complete.)
241
 
242
        * cdl/hal_i386.cdl:
243
        Added options for building a bootstrap ROM.
244
        (This is work in progress and is not yet complete.)
245
 
246
        * include/basetype.h:
247
        Returned alignment to 32 bytes, now that I have discovered, the
248
        hard way, why it was that value in the first place.
249
 
250
        * src/i386.ld: Force alignment of tables to 32 bytes.
251
 
252
        * include/hal_arch.h (HAL_THREAD_INIT_FPU_CONTEXT_SPACE): Fixed
253
        compiler warning.
254
 
255
2001-03-14  Nick Garnett  
256
 
257
        [x86 branch]
258
        * src/vectors.S:
259
        Removed memory size stuff.
260
        Moved BSS zero code here to avoid doing a procedure call. The
261
        interrupt stack is in the BSS so zeroing it would blow the return
262
        address away.
263
        Moved interrupt stack to BSS.
264
 
265
        * src/hal_misc.c: Removed hal_zero_bss(), hal_lsbit_index() and
266
        hal_msbit_index() functions.
267
 
268
        * include/hal_arch.h:
269
        Replaced hal_[lm]sbit_index() functions with inline assembler
270
        using the bsf and bsr instructions.
271
        Added support for dynamic memory size finder.
272
 
273
        * cdl/hal_i386.cdl:
274
        Added interface CYGINT_HAL_I386_MEM_REAL_REGION_TOP.
275
 
276
2001-03-13  Nick Garnett  
277
 
278
        [x86 branch]
279
        * src/vectors.S: Enabled FPU support.
280
        Added FPU state save and restore macros to default exception and
281
        interrupt VSRs.
282
        Added __fpu_switch_vsr to perform lazy context switch of FPU
283
        state.
284
        Made use of i386reg_xxx definitions.
285
 
286
        * src/context.S: Added FPU save and restore macros to thread
287
        switch code. Made use of i386reg_xxx definitions.
288
 
289
        * include/hal_arch.h: Added HAL_FPU_Context structure to contain
290
        FPU state. Added code to HAL_THREAD_INIT_CONTEXT() to create
291
        FPU context.
292
 
293
        * include/i386.inc: Updated savestate format in line with hal_arch.h
294
 
295
        * include/arch.inc: Added macros to implement FPU initialization,
296
        save and restore for threads, exceptions and interrupts.
297
 
298
        * cdl/hal_i386.cdl: Added initial FPU configuration options.
299
 
300
2001-03-09  Nick Garnett  
301
 
302
        [x86 branch]
303
        * src/vectors.S:
304
        Added support for use of interrupt stack, together with support
305
        for running DSRs on it.
306
        Added instrumentation support to default interrupt VSR.
307
        Miscellaneous tidies to code and comments.
308
 
309
        * src/context.S:
310
        Rewrote context switch code to permit preservation of the
311
        interrupt disable state of a thread. This is to support use of an
312
        interrupt stack, calling DSRs on it and brings the i386 HAL in
313
        line with other HALs.
314
 
315
        * include/hal_intr.h:
316
        Added HAL_INTERRUPT_STACK_CALL_PENDING_DSRS(),
317
        HAL_INTERRUPT_STACK_BASE and HAL_INTERRUPT_STACK_TOP.
318
 
319
        * include/i386.inc:
320
        * include/hal_arch.h:
321
        * src/i386_stub.c:
322
        Changed naming of last two HAL_SavedRegisters fields.
323
        Modified HAL_THREAD_INIT_CONTEXT() to match new context switch
324
        code.
325
 
326
2001-03-08  Nick Garnett  
327
 
328
        [x86 branch]
329
        * src/vectors.S: Eliminated some unnecessary code. Tidied up some
330
        comments.
331
 
332
        * include/hal_intr.h:
333
        Moved common exception vector definitions here.
334
        Moved CPU interrupt enable/disable macros here.
335
 
336
        * include/hal_arch.h:
337
        * src/i386_stub.c:
338
        Converted arguments to hal_[g|s]et_gdb_registers() to CYG_ADDRWORD
339
        from target_register_t.
340
 
341
        * include/arch.inc:
342
        Moved FPU control stuff here - this still needs a lot of work to
343
        get running.
344
        Moved A20 gate enable macro here. Since the A20 gate stuff is part
345
        of all recent CPUs, this has become an architectural feature.
346
 
347
2001-03-06  Nick Garnett  
348
 
349
        [x86 branch]
350
        * include/hal_arch.h: Added CYGARC_CACHED_ADDRESS() and friends.
351
 
352
2001-03-05  Nick Garnett  
353
 
354
        [x86 branch]
355
        * src/hal_misc.c (hal_arch_default_isr): Restored diag_printf() in
356
        here. Without the reference, RedBoot does not include anything
357
        from infra/diag.cxx, does not call HAL_DIAG_INIT() and will not
358
        mangle diagnostic output.
359
 
360
2001-03-02  Nick Garnett  
361
 
362
        [x86 branch]
363
        Some of these changes here were initially made by Fabrice Gautier
364
        and then liberally modified by me.
365
 
366
        * src/vectors.S:
367
        Removed Synthetic target support - this is moving to its own HAL.
368
        Added __default_exception_vsr to capture exceptions.
369
        Renamed hal_pc_generic_interrupt to __default_interrupt_vsr in
370
        line with other HALs. Generally tidied and polished.
371
        Added VSR entry trampolines.
372
        Added interrupt stack definition.
373
 
374
        * src/i386_stub.c: Removed a lot of unnecessary stuff.
375
 
376
        * src/i386.ld: Added absolute defines for IDT, VSR and virtual
377
        vector tables.
378
 
379
        * src/hal_misc.c: Tidied up and added eCos exception support.
380
 
381
        * src/context.S:
382
        Modified to save and restore context in new format.
383
 
384
        * include/i386_stub.h:
385
        Added definition of HAL_STUB_PLATFORM_STUBS_FIXUP() macro.

        * src/crt_begin.c: Removed.
803
        * src/PKGconf.mak: Compile crtbegin.c to create the correct file
804
        for linking. This is to turn on init-priority for i386 linux target.
805
 
806
        The default i386 linker script looks for the file named crtbegin.o
807
        and then looks for the .ctors section within that file to
808
        determine where to put the sorted constructors.
