mhitch 44c123573b Define PC_ADVANCE() to advance the PC around the break instruction only
if the break instruction is still there.  This works around a problem with
the software single step in DDB not recognizing the temporary breakpoint
set to emulate the single step.

thorpej a15938129d asm -> __asm__ 1997-11-05 04:02:26 +00:00
thorpej 4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

thorpej 665f7d1a6e Implement __RENAME() in <machine/cdefs.h> 1997-10-22 05:20:32 +00:00
jonathan 4d29dd99dd Put back duplicate <XXX>_ENDIAN definitions. Defining them as _<XXX>_ENDIAN
loses on non-POSIX source that re-defines <XXX>_ENDIAN itself (e.g., gdb.)
1997-10-20 19:15:40 +00:00
jonathan a03a434f1b * Use ANSI-clean names for host-specific byte-order definition
(_BYTE_ORDER, _BIG_ENDIAN, _LITTLE_ENDIAN).
  Define old names from the ANSI ones if not _POSIX_SOURCE.
* Define _QUAD_HIGHWORD and _QUAD_LOWWORD properly when
  _BYTE_ORDER == _BIG_ENDIAN.

jonathan 92ed4b0f7f Make the __mcount entrypoint non-static for kernels, to avoid any
chance of gprof mis-report profile ticks in __mcount to  the following
function in libkern (currently _qdivrem).

mhitch c7422c2d87 Fix typo - list/libc/gen/nlist_ecoff.c still wasn't compiling. 1997-10-15 00:59:01 +00:00
jonathan 2ebcc702b9 Don't check the actual CPU type unless we're in the _KERNEL, or
src/lib/libc/gen/nlist_ecoff.c breaks.

bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

jonathan 003ccf3b1c mips pmap_activate:
* prototype and definition for pmap_activate(p). Updates the segtab,
   and changes the active ASID if p == curproc.
 * Make reserved fixed-address (UADDR) kernelstack PTEs global,
   so we still have a kernel stack after pmap_activate() on curproc.
 * make KSEG2 mappings for p_addr global (see above.)

Seems to detune contextswitch and NTP resolution (by 60 ms), but
thepmap_activate() interface is mandatory.  Needs more thought.

jonathan fd7a6758c8 Don't emit ".set reorder ; .set noreorder" around mcount profiling
stubs if _LOCORE or _KERNEL are defined,.  _LOCORE means we're
compiling locore. Locore assumes ".set noreorder" for the whole file.

jonathan 39814d8abc Add pointer to _mcount to avoid bogus warnings about unused static function.
(calls from interpolated assembler are invisible to gcc.)

If _KERNEL, add prototypes for non-profiled entrypoints _splhigh(), _splx().

jonathan ccf3801c92 * Re-apply changes from rev 1.6 of sys/arch/mips/include/reg.h accidentally
undone by rev 1.7:
  >redo pmax/include/reg.h
  >so that the definitions needed by locore.S are in a separate file,
  >pmax/include/regnum.h.

* Add explicit `#include <mips/regnum.h>'  where symbolic offsets
  into a mips trapframe or struct reg are used..

jonathan 1490cbcf7b Rewrite struct ecoff_symhdr using the same field ordering as GNU
binutils and the MipsCo toolchain, not the Alpha ordering (which has a
block of int32_t symbol counts and a block of long offsets) .

jonathan d1ec048977 DDB for mips.
Add DDB interface to /sys/arch/mips/mips..
  Rework heuristic stack traceback to work with DDB.
  Add hooks  to print exception log from DDB.
  Add hooks from pmax console drivers:   call Debugger()
  after break from serial console, or 'DO' key from LK-xxx.

jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the
  (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).

jonathan b86aa7f311 Fix typo mips3_mips_switch_exit. 1997-06-22 04:30:01 +00:00
jonathan 4692a37162 Final changes for configuring MIPS1 and MIPS3 in a single kernel.
* cpuregs.h:
    rename remaining VMMACH_xxx TLB macros to MIPS_TLB_xxx.
    Add compile-time MIPS3-only, compile-time  MIPS1-only, and
    runtime (both) definitions  for number of TLB ASIDs (tlb pids)
    and shift count to extract a TLB pid.

  * locore.h:
    Delete unused vector slot for indexed TLB writes.
    mips1 and mips3 TLBs are different enough that we have
    to break them out at the caller anyway.

  * Add compile-time MIPS3-only andcompile-time  MIPS1-only
    macros to call locore functions directly by name.
    Use the  existing method table only if

  * mips/mips_machdep.c, mips/trap.c, mips/pmap.c, pmax/machdep.c:
    Use MIPS3_ or MIPS1_ specific names for TLB pids in
    mips3 and mips1 specific code paths (e.g., creating the kernel stack
    for process 0).

Add `options MIPS3' to pmax/conf/GENERIC.

mhitch b027d98eb5 MachHitFlushDCache is gone. 1997-06-21 04:52:26 +00:00
jonathan 68863ebd8e More mips1/mips3 changes to cpuregs.h and psl.h:
* cpuregs.h:
  Delete unused VMMACH_ names (e.g., duplicates of PTE bits in  pte.h).
  Change remaining VMMACH_xxx  names to MIPS1_xxx or MIPS3_xx.
  Fold remaining compile-time definitions into a single #ifdef MIPS3.

* Use MIPS1_ names  in locore_r2000.S, mips3_ names in locore_r4000.S

* Garbage-collect MachHitFlushDCache()

* psl.h:
  use MIPS1_, MIPS3_  symbolic names for Cause register bits.
  change  _R3K to MIPS1_,  _R4K to MIPS3. Conditionalize for mips1 only,
  mips3 only, or when both are defined,  use runtime CPUISMIPS3 test.
1997-06-21 04:18:09 +00:00
mhitch e03cf7a95c Cast mips1-only and mips3-only pfn_to_vad() macros to match the mips1/mips3
merged inline function.  Fixes inconsist printf format usage in trap.c.
1997-06-21 04:10:42 +00:00
mhitch 4fa507b4fc More merged mips1/mips3 support:
Remove cpu-specific routines from locore.S and add them to locore_r2000.S
and locore_r4000.S.  Add entries in locore jump vector table for switch_exit()
and the cpu_switch() context resume.
Add offsets into the jump vector to genassym.cf for use in locore.S.
1997-06-19 06:31:14 +00:00
mhitch 806f730e87 Remove stray macro definition; didn't hurt for MIPS1 only, but wrong for
MIPS3.
1997-06-17 04:12:38 +00:00
jonathan fef3e76b31 Changes for configuring both MIPS1 and MIPS3, from a merge of
similar design and code by Jason Thorpe and Jonathan Stone.

NOTE: the kernel-stack-switching code and cacheflush() calls in
locore.S still use #ifdef MIPS3 and need more work.

mips/include/cpu.h:
    Add CPUISMIPS3 for run-time tests of what CPU architecture level
    we're running on.

mips/include/locore.h:
    Add declarations of locore cache-size variables for ref/def toolchain.

mips/include/mips1_pte.h:
    mips1 TLB bit definitions.

mips/include/mips3_pte.h:
    mips3 TLB bit definitions.

mips/include/pte.h:
    define accesor macros for TLB bits (e.g., mips_pg_m_bit(),
    that expand to CPU constants if only one CPU arch is configured,
    or to inline functions if both MIPS1 and MIPS3 are configured.

mips/mips/locore_r2000.S:
    Use MIPS1_PG_xxx constants inside mips1-specific code.

mips/mips/locore_r4000.S:
    Use MIPS3_PG_xxx constants inside mips3-specific code.

mips/mips/locore.S:
    Use MIPS1_PG_xxx constants inside mips3-specific code.
    Use MIPS1_PG_xxx constants inside mips1-specific code.
    (Needs more  work!)

mips/mips/{pmap.c,vm_machdep.c,trap.c}, pmax/pmax/machdep.c:
    Use MIPS3_PG_xxx constants inside mips3-specific functions,
         and MIPS1_PG_XXX inside mips1-specific code.
    Otherwise, use mips_pg_XXX_bit() macros where they apply,
    and use "if (CPUISMIPS3) { ... } else {... }" where they don't.

mips/mips/mips_machdep.c:
    Import Michael Hitch's fixes from the pmax locore-init code
    into mips_vector_init().

pmax/pmax/machdep.c:
    Use generic mips_vector_init() locore vector-init function.
1997-06-16 23:41:40 +00:00
jonathan eb1d8427cc Garbage-collect redundant declarations:
mips/include/locore.h:
  Add prototypes for HitFlushDCache() functions. Moe cpu_prid definition here.
mips/include/cpu.h:
  remove  cpu_prid definition.
pmax/pmax/machdep.c:
   remove local protoypes of HitFlushDCache() functions.
mips/mips/vm_machdep.c, mips/mips/vm_machdep.c::
   remove local protoypes of HitFlushDCache() functions.
1997-06-16 09:50:26 +00:00
jonathan 2d10220f8f Yet more mips1/mips3 merging:
Move mips-specific pmap definitions (PMAP_PREFER for mips3, declaratin
of pmap_bootstrap() for the system-specific machdep.c) from
arch/pmax/include/pmap.h to arch/mips/include/pmap.h.
1997-06-16 07:47:42 +00:00
jonathan df6533a42e Fix idempotent inclusion test macro: _MACHCONST -> _MIPS_CPUREGS_H_
to avoid collision with obsolete Sprite-derived NetBSD/pica  header file.
