Go to most recent revision | Compare with Previous | Blame | View Log
2001-11-26 Jesper Skov <jskov@redhat.com>
* src/hal_misc.c (hal_msbit_index): Fixed.
2001-04-24 Jonathan Larmour <jlarmour@redhat.com>
* src/vectors.S: Support daft platforms like the CEB which have
default on-chip flash that vector NMI to 2 insns after reset.
Also place hal_v85x_ice_syscall_info in fixed location, only
for ROM/ROMRAM builds.
2001-03-28 Jonathan Larmour <jlarmour@redhat.com>
* src/vectors.S: Overhaul...
Make interrupt processing path faster, especially by implementing
CYGDBG_HAL_COMMON_INTERRUPTS_SAVE_MINIMUM_CONTEXT
Add ROMRAM startup support
Pass in correct argument to exception_handler
Call DSRs with parameter flushback area
Add __allow_nmi as a somewhat kludgy means of determining
whether NMIs should be ignored - important if the board resets
and the vector tables are temporarily inconsistent.
Initialize __vsr_table statically.
Add some generic elements of ICE debugging support
* src/v85x.ld: Remove - redundant.
* src/hal_mk_defs.c (main): Update to reflect new vector names
(to match official NEC docs)
* src/hal_misc.c (exception_handler): Remove cygmon cruft.
(hal_arch_default_isr): Report spurious interrupts.
(hal_idle_thread_action): use halt instruction
* include/hal_arch.h: Remove obsolete comment reference to arch.inc.
* include/basetype.h: No need to include <pkgconf/hal.h>
* include/hal_io.h: Ditto.
* include/nec-stub.h: Similarly for <pkgconf/system.h>
* cdl/hal_v85x.cdl: Move CYGHWR_HAL_V85X_CPU_FREQ into platforms
(and make Hz, not MHz).
Add generic ICE debugging interface.
Description tidies.
2001-01-26 Jonathan Larmour <jlarmour@redhat.com>
* include/hal_intr.h: Move HAL_STUB_PLATFORM_RESET and
HAL_STUB_PLATFORM_RESET_ENTRY here from platform stub headers.
Also rename to HAL_PLATFORM_RESET and HAL_PLATFORM_RESET_ENTRY
* src/vectors.S (_hal_reset_board): Renamed from hal_plf_reset_board
2001-01-18 Nick Garnett <nickg@cygnus.co.uk>
* src/vectors.S: Added underscore to reference to
cyg_scheduler_sched_lock, since CYGBLD_ATTRIB_ASM_ALIAS() now adds
one automatically.
2000-10-20 Jesper Skov <jskov@redhat.com>
* src/hal_misc.c: Update __mem_fault_handler declaration.
2000-10-16 Jonathan Larmour <jlarmour@redhat.com>
* include/hal_arch.h (CYGARC_JMP_BUF_SIZE): Define hal_jmp_buf in
terms of this.
2000-10-09 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (start): Need to handle ^C for all applications.
2000-09-13 Jonathan Larmour <jlarmour@redhat.com>
* src/vectors.S: When calling C functions, ensure there is 16 bytes
space for the parameter flushback area (as per the calling convention)
on the stack
2000-09-07 Jonathan Larmour <jlarmour@redhat.com>
* include/basetype.h: Don't need special alignment after all - it was
a bug elsewhere.
2000-09-06 Gary Thomas <gthomas@redhat.com>
* include/basetype.h: Need special alignment to match the way
the compiler/linker actually do things.
* cdl/hal_v85x.cdl: Improve variant handling and specification.
2000-08-30 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (start): Allow programs to field NMI exceptions.
2000-07-24 Jonathan Larmour <jlarmour@redhat.co.uk>
* include/basetype.h: Removed definition of CYG_LABEL_NAME().
* src/v85x.ld: Switched to new table definition mechanism.
2000-07-21 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (_hal_plf_reset_board): Needs to be defined in all
configurations.
2000-06-27 Jesper Skov <jskov@redhat.com>
* src/vectors.S:
* src/hal_mk_defs.c:
Fix compiler warnings.
* src/hal_misc.c (hal_default_isr): Let common version do the
checks.
2000-06-15 Gary Thomas <gthomas@redhat.com>
* src/hal_mk_defs.c:
* src/vectors.S:
* src/hal_misc.c (hal_default_isr): Update for new debug
vector support.
* include/hal_intr.h:
* src/vectors.S (do_interrupt): Proper handling of chained
interrupts.
2000-06-12 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (return_from_exception_or_interrupt): Revert
reorg change (05-26) which broke GDB breakpoints.
2000-06-08 Jesper Skov <jskov@redhat.com>
* include/hal_arch.h (CYGARC_HAL_SAVE_GP, CYGARC_HAL_RESTORE_GP):
Added.
2000-05-26 Gary Thomas <gthomas@redhat.com>
* src/vectors.S: Slight reorg of trap vectors (more readable).
2000-05-25 John Dallaway <jld@redhat.com>
* cdl/hal_v85x.cdl: Tidy display strings.
2000-05-25 Gary Thomas <gthomas@redhat.com>
* src/vectors.S: Handle different chips (number of interrupt
sources differs, exception table is altered, etc).
* include/hal_intr.h: Actual interrupt layout now defined by
variant/platform since these differ depending on the chip.
2000-05-03 Gary Thomas <gthomas@redhat.com>
* include/hal_arch.h: New breakpoint instruction ("br *").
2000-04-14 Gary Thomas <gthomas@redhat.com>
* src/hal_misc.c (exception_handler): Proper handling of nested
[watchdog] interrupts - don't corrupt GDB registers.
* src/hal_mk_defs.c: Add some symbols required for NMI handling.
* src/vectors.S (return_from_exception_or_interrupt):
Properly handle different cases for exception, NMI and ISR.
* include/hal_intr.h (HAL_TRANSLATE_VECTOR): Ignore interrupt
chaining - doesn't happen on this hardware.
2000-04-11 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (exception): Handle NMI. In particular, need to
have appropriate bits set so they clear and also get the state
from the proper save registers.
(exception): Register save was wrong - ROM only.
2000-03-31 Gary Thomas <gthomas@redhat.com>
* src/hal_mk_defs.c: Add definition for 'ep' register.
* include/hal_intr.h:
* cdl/hal_nec.cdl: Add config option to choose between inline and
real functions for interrupt macros.
* src/vectors.S: Tune up - use SLD/SST for smaller, faster code
in context load/save routines. Also remove IRQ trace/debug code.
2000-03-30 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (do_interrupt): Can't use R13 across function calls.
This caused instability when turning on kernel instrumentation.
* include/hal_intr.h: Use out-of-line code for interrupt functions
for tracing/testing.
* src/vectors.S: Working support for separate interrupt stack.
Some debug/trace code left in.
* src/hal_mk_defs.c:
* include/hal_arch.h: Documented API does not match actual GCC
register usage. Need to save R1/R2/R4/R5 for setjmp/longjmp.
2000-03-27 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (do_interrupt): Pass regs to ISR & DSR.
* include/basetype.h: Endian-ness was incorrect.
* include/hal_arch.h:
* src/hal_mk_defs.c: Complete setjmp/longjmp support.
* src/vectors.S: Add interrupt stack.
2000-03-21 Gary Thomas <gthomas@redhat.com>
* src/vectors.S (_hal_plf_reset_board): Add board reset function.
* include/hal_arch.h (CYGHWR_TEST_PROGRAM_EXIT): Define RESET for ROM
based programs.
