3 * include/hal_arch.h: #define CYGARC_VIRTUAL_ADDRESS.
5 2005-04-22 David Vrabel <dvrabel@arcom.com>
7 * cdl/hal_i386.cdl (CYGHWR_REDBOOT_I386_TRAMPOLINE_ADDRESS): Don't
8 require CYGINT_HAL_I386_PCMB_SCREEN_SUPPORT so we can use the exec
9 command on platforms without a screen.
11 2005-04-21 David Vrabel <dvrabel@arcom.com>
13 * src/i386_stub.c: Rename the local memcpy function to
14 local_memcpy so it doesn't conflict with later GCC's built-in
17 * src/i386.ld: Add .2ram section.
19 2005-04-17 Andrew Lunn <andrew.lunn@ascom.ch>
22 * src/redboot_linux_exec.c: Moved the RedBoot command "exec" from
23 the pc package to this generic package.
25 2005-03-21 Bart Veer <bartv@ecoscentric.com>
27 * src/vectors.S, src/hal_misc.c, cdl/hal_i386.cdl: add profiling

33 Invoke tail with stricter syntax that works in latest coreutils.
35 2003-12-08 Gary Thomas <gary@mlbassoc.com>
37 * src/hal_misc.c: Only declare __mem_fault_handler if GDB stubs
38 are included (and it will be used).
40 2003-07-23 Nick Garnett <nickg@balti.calivar.com>
42 * include/hal_intr.h: Tidied up some compiler warnings.
44 2003-04-10 Nick Garnett <nickg@balti.calivar.com>
47 Added libsupc++.a to GROUP() directive for GCC versions later than
50 2003-01-31 Mark Salter <msalter@redhat.com>
52 * src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
55 2002-11-28 Nick Garnett <nickg@ecoscentric.com>
57 * src/vectors.S: Added GRUB startup option to tests for IDT
58 initialization. Added call to breakpoint() before cyg_start(),
59 controlled by CYGDBG_HAL_DEBUG_GDB_INITIAL_BREAK.
61 2002-05-17 Nick Garnett <nickg@redhat.com>
63 * src/vectors.S: Rearranged interrupt stack definitions to make it
64 work correctly in SMP case. The #ifdefs were improperly nested.
66 2002-04-29 Jonathan Larmour <jlarmour@redhat.com>
69 Don't use .file as it can confuse debugging since the .file
70 doesn't contain the path and therefore the debugger will never
71 know where it lives! This conflicts with using -Wa,--gstabs.
73 2002-04-15 Jonathan Larmour <jlarmour@redhat.com>
75 * src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
78 2002-01-08 Nick Garnett <nickg@redhat.com>
81 Removed consideration of lazy FPU context switching in determining
82 the size of CYGNUM_HAL_STACK_CONTEXT_SIZE, since it does not
83 actually make any difference - and previously resulted in too
84 small a value for CYGNUM_HAL_STACK_SIZE_MINIMUM.
86 2002-01-07 Nick Garnett <nickg@redhat.com>
88 * src/vectors.S (__fpu_switch_vsr): Fixed register usage bug.

101 2001-12-07 Jonathan Larmour <jlarmour@redhat.com>
103 * src/i386.ld: Add missing close bracket.
105 2001-12-06 Jonathan Larmour <jlarmour@redhat.com>
107 * src/i386.ld: Add .rel.text and .rel.data sections to avoid
108 linker warnings, which can cause the linker to then get confused.
111 2001-11-21 Mark Salter <msalter@redhat.com>
113 * src/i386_stub.c (__do_read_msr): Add mem_fault handling.
114 (__do_write_msr): Ditto.
116 2001-10-19 Ian Campbell <icampbell@arcom.co.uk>
118 * include/hal_cache.h: Provide HAL_DCACHE_IS_ENABLED and
119 HAL_ICACHE_IS_ENABLED macros.

136 CYGHWR_HAL_I386_PENTIUM_SSE.
137 * cdl/hal_i386.cdl: Add CYGHWR_HAL_I386_PENTIUM_GDB_REGS.
139 2001-10-08 Ian Campbell <icampbell@arcom.co.uk>
141 * cdl/hal_i386.cdl: move CYGBLD_BUILD_I386_ROMBOOT and
142 CYGBLD_BUILD_REDBOOT_BIN_ROM to pc package.
143 * src/romboot.S: Moved to pc package
144 * src/romboot.ld: Moved to pc package

152 2001-10-10 Jonathan Larmour <jlarmour@redhat.com>
154 * src/vectors.S: Don't use apostrophes in comments as it can confuse
155 preprocessors sometimes.
157 2001-10-05 Mark Salter <msalter@redhat.com>
159 * src/vectors.S: Support separate stub stack.
160 (__syscall_tramp): Trampoline for GNUPRo syscalls (int $0x80).
162 * src/i386_stub.c (__is_bsp_syscall): New function.
164 * src/hal_misc.c (cyg_hal_exception_handler): Add mem fault handling.
166 * cdl/hal_i386.cdl: Add hal_syscalls.c to compile list.

170 2001-10-01 Ian Campbell <icampbell@arcom.co.uk>
172 * src/vectors.S: include CYGBLD_HAL_PLATFORM_H rather than
173 <pkgconf/hal_i386_pc.h>
175 2001-09-05 Jonathan Larmour <jlarmour@redhat.com>
177 * src/vectors.S (__default_interrupt_vsr): Adjust saved stack pointer
178 for the hardware and trampoline saved data.

185 2001-08-22 Nick Garnett <nickg@redhat.com>
187 * include/hal_io.h: Added some macros to do in-memory data
188 accesses for memory mapped devices.
190 * include/hal_arch.h: Attempted to make some sense out of the
193 * include/hal_intr.h: Extended VSR table to its full 256 entries.
195 * src/vectors.S: Lots of changes to incorporate SMP support.
197 * src/i386.ld: Added SMP related data, that must be shared between
198 RedBoot and applications, for example.
200 * include/hal_smp.h: Added this file to define SMP related HAL
203 * include/arch.inc: Added SMP support. This includes explicit SMP
204 macros and stack-switching macros that have single CPU and SMP
205 variants. Some SMP modifications to the lazy FPU switching code
206 leave it functional in the single CPU case, but do not yet work in
207 the SMP case. Lazy FPU switching is currently disabled for SMP in
210 * cdl/hal_i386.cdl: Added SMP configury.
212 2001-07-31 Jonathan Larmour <jlarmour@redhat.com>
214 * src/hal_misc.c: Fix "implicit decl of diag_printf" warning.
216 2001-07-13 Nick Garnett <nickg@redhat.com>
219 Added code to clear CR0:TS bit in hal_fpu_init macro. If this bit
220 is not clear, then the following finit might trap, and we don't
222 Added a compare to hal_fpu_push_exc macro for a zero fpu state
223 owner. The code was assuming the move set the condition codes,
226 2001-07-08 Jonathan Larmour <jlarmour@redhat.com>
228 * include/hal_arch.h (HAL_THREAD_INIT_FPU_CONTEXT): Fix indirection to

236 2001-07-04 Jonathan Larmour <jlarmour@redhat.com>
238 * include/hal_intr.h: Be pedantic about register constraint syntax
239 to satisfy newer compilers
240 * include/hal_io.h: Ditto
242 2001-06-13 Jonathan Larmour <jlarmour@redhat.com>
244 * cdl/hal_i386.cdl: Default to enabling FPU support since gcc assumes
245 a hardware FPU anyway. Also default to lazy FPU switching since
246 this is cheapest in the modal case.
248 2001-05-01 Nick Garnett <nickg@cygnus.co.uk>
251 * src/context.S: Fixed bug in hal_setjmp() that corrupted EBX.
253 2001-04-26 Nick Garnett <nickg@cygnus.co.uk>
256 * include/hal_intr.h:
257 Tidied up mapping of exceptions to vectors. Added implementation
258 of HAL_VSR_SET_TO_ECOS_HANDLER().
260 2001-04-19 Nick Garnett <nickg@cygnus.co.uk>
263 * src/vectors.S (__default_exception_vsr):
264 Disabled ROM monitor stack switching here. There are problems with
265 this that I do not have time to worry about now.
267 2001-03-30 Nick Garnett <nickg@cygnus.co.uk>
270 * src/romboot.S: Added code to call video BIOS to initialize
273 * src/vectors.S: Added code to copy data section from ROM to RAM
274 in ROM booted systems.
276 2001-03-16 Nick Garnett <nickg@cygnus.co.uk>
281 Added these files to build 256 byte realmode bootstrap at the top
283 (This is work in progress and is not yet complete.)
286 Added options for building a bootstrap ROM.
287 (This is work in progress and is not yet complete.)
289 * include/basetype.h:
290 Returned alignment to 32 bytes, now that I have discovered, the
291 hard way, why it was that value in the first place.
293 * src/i386.ld: Force alignment of tables to 32 bytes.
295 * include/hal_arch.h (HAL_THREAD_INIT_FPU_CONTEXT_SPACE): Fixed
298 2001-03-14 Nick Garnett <nickg@cygnus.co.uk>
302 Removed memory size stuff.
303 Moved BSS zero code here to avoid doing a procedure call. The
304 interrupt stack is in the BSS so zeroing it would blow the return
306 Moved interrupt stack to BSS.
308 * src/hal_misc.c: Removed hal_zero_bss(), hal_lsbit_index() and
309 hal_msbit_index() functions.
311 * include/hal_arch.h:
312 Replaced hal_[lm]sbit_index() functions with inline assembler
313 using the bsf and bsr instructions.
314 Added support for dynamic memory size finder.
317 Added interface CYGINT_HAL_I386_MEM_REAL_REGION_TOP.
319 2001-03-13 Nick Garnett <nickg@cygnus.co.uk>
322 * src/vectors.S: Enabled FPU support.
323 Added FPU state save and restore macros to default exception and
325 Added __fpu_switch_vsr to perform lazy context switch of FPU
327 Made use of i386reg_xxx definitions.
329 * src/context.S: Added FPU save and restore macros to thread
330 switch code. Made use of i386reg_xxx definitions.
332 * include/hal_arch.h: Added HAL_FPU_Context structure to contain
333 FPU state. Added code to HAL_THREAD_INIT_CONTEXT() to create
336 * include/i386.inc: Updated savestate format in line with hal_arch.h
338 * include/arch.inc: Added macros to implement FPU initialization,
339 save and restore for threads, exceptions and interrupts.
341 * cdl/hal_i386.cdl: Added initial FPU configuration options.
343 2001-03-09 Nick Garnett <nickg@cygnus.co.uk>
347 Added support for use of interrupt stack, together with support
348 for running DSRs on it.
349 Added instrumentation support to default interrupt VSR.
350 Miscellaneous tidies to code and comments.
353 Rewrote context switch code to permit preservation of the
354 interrupt disable state of a thread. This is to support use of an
355 interrupt stack, calling DSRs on it and brings the i386 HAL in
356 line with other HALs.
358 * include/hal_intr.h:
359 Added HAL_INTERRUPT_STACK_CALL_PENDING_DSRS(),
360 HAL_INTERRUPT_STACK_BASE and HAL_INTERRUPT_STACK_TOP.
363 * include/hal_arch.h:
365 Changed naming of last two HAL_SavedRegisters fields.
366 Modified HAL_THREAD_INIT_CONTEXT() to match new context switch
369 2001-03-08 Nick Garnett <nickg@cygnus.co.uk>
372 * src/vectors.S: Eliminated some unnecessary code. Tidied up some
375 * include/hal_intr.h:
376 Moved common exception vector definitions here.
377 Moved CPU interrupt enable/disable macros here.
379 * include/hal_arch.h:
381 Converted arguments to hal_[g|s]et_gdb_registers() to CYG_ADDRWORD
382 from target_register_t.
385 Moved FPU control stuff here - this still needs a lot of work to
387 Moved A20 gate enable macro here. Since the A20 gate stuff is part
388 of all recent CPUs, this has become an architectural feature.
390 2001-03-06 Nick Garnett <nickg@cygnus.co.uk>
393 * include/hal_arch.h: Added CYGARC_CACHED_ADDRESS() and friends.
395 2001-03-05 Nick Garnett <nickg@cygnus.co.uk>
398 * src/hal_misc.c (hal_arch_default_isr): Restored diag_printf() in
399 here. Without the reference, RedBoot does not include anything
400 from infra/diag.cxx, does not call HAL_DIAG_INIT() and will not
401 mangle diagnostic output.
403 2001-03-02 Nick Garnett <nickg@cygnus.co.uk>
406 Some of these changes here were initially made by Fabrice Gautier
407 and then liberally modified by me.
410 Removed Synthetic target support - this is moving to its own HAL.
411 Added __default_exception_vsr to capture exceptions.
412 Renamed hal_pc_generic_interrupt to __default_interrupt_vsr in
413 line with other HALs. Generally tidied and polished.
414 Added VSR entry trampolines.
415 Added interrupt stack definition.
417 * src/i386_stub.c: Removed a lot of unnecessary stuff.
419 * src/i386.ld: Added absolute defines for IDT, VSR and virtual
422 * src/hal_misc.c: Tidied up and added eCos exception support.
425 Modified to save and restore context in new format.
427 * include/i386_stub.h:
428 Added definition of HAL_STUB_PLATFORM_STUBS_FIXUP() macro.
430 * include/hal_io.h: Implemented these macros as inline assembler.
432 * include/hal_intr.h: Various changes to interrupt and VSR table
435 * include/hal_arch.h:
437 Redfined HAL_SavedRegisters structure and init macro. Now all
438 contexts consist of a full register set, vector number, and
439 PC,CS,EFLAGS as pushed by the hardware.
441 * include/basetype.h: Changed alignment to 4 bytes.
443 2000-11-01 Jonathan Larmour <jlarmour@redhat.com>

446 when calling interrupt_end()
447 Thanks to Phil Hinton for reporting.
449 2000-10-20 Jonathan Larmour <jlarmour@redhat.com>
451 * src/vectors.S (_start): call constructors after initializing
452 stub so that they can be debugged. Reported to work okay
455 2000-09-05 Jonathan Larmour <jlarmour@redhat.com>
457 * include/basetype.h: Use 32-byte alignment
459 2000-08-14 Jonathan Larmour <jlarmour@redhat.co.uk>

468 underscore to _breakinst.
470 * src/i386.ld: Switched to new table definition mechanism.
472 * include/basetype.h: Removed definition of CYG_LABEL_NAME().
474 2000-06-08 Jesper Skov <jskov@redhat.com>
476 * include/hal_arch.h (CYGARC_HAL_SAVE_GP, CYGARC_HAL_RESTORE_GP):
479 2000-03-27 Jonathan Larmour <jlarmour@redhat.co.uk>

580 (rather conservatively) before use.
582 1999-04-28 Bart Veer <bartv@cygnus.co.uk>
585 Remove the -n argument to tail, it does not appear to be required
586 on any supported host and causes problems with some
587 implementations of tail.
589 1999-04-14 Jonathan Larmour <jlarmour@cygnus.co.uk>
591 * src/PKGconf.mak (EXTRAS): Don't generate extras.o here any more
