thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
lukem e4a87aa1a9 * convert to using MI allocsys(). most ports were using an MD allocsys(),
although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes

nisimura c99765853f - Move MachSetPID(1) call to pmap_bootstrap() adajacent to kernel pmap
initialization code.
- Abandon mips_init_proc0() and do the 4 lines straightly in MD mach_init().
- Restore a block of code accidentally lost in prevous commit.
- Change the term 'tlbpid' to a MIPS3 nomenclature 'asid'.
- Hide PTE size exposures by symbolic names in locore.S

simonb 027594b1eb Add CPU_BOOTED_KERNEL to CTL_MACHDEP definition. 1999-03-23 22:04:01 +00:00
castor a84ec5a3c1 * Create mips_reg_t data type to allow register size to be
decoupled from long or int or long long.  Define macros in asm.h to facilitate
  choosing these on a port by port basis.

* Create <machine/pubassym.h> mechanism to allow jmp_buf structure size
  to be calculated at system build time.

* Define _MIPS_BSD_SIM macro which specifies what calling style is appropritae
  for the architecture.  For 64-bit oriented systems set the Status Register
  to allow 64-bit instructions.

* Remove UADDR related macros because kernel U structure is now mapped
  normally.
* Separate cpu.h into cpu.h and cpuarch.h to keep things neat.
* Add support for QED 52xx processors

thorpej 49c62c4336 Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

jonathan dd735283c1 Add `struct proc;' to keep egcs warnings happy in userland.
XXX why are kernel prototypes visible here at all?

jonathan 008816ea4f Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>.
Adds (most) support for ARC platform to port-independent mips code.

Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.

Open issues:
 * Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
   Code derived from Per Fogelstrom's OpenBSD source  doesn't work
   on mips3 pmaxes with L2 cache.

 * Still some port-specific  #ifdefs, for interrupt enable and
   pmax L2 cache-size.  Needs more thought, but overlaps with
   work-in-progress by Tohru and Tsubai on spl()s and related stuff.

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 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.

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 5db35a8cce Yet more merging:
* Move declaration of locore communcation variables (CPU family,
     cache sizes, etc) to mips/include/locore.h.  Delete from
     pmax/include/cpu.h and older versions from pica/include/cpu.h.

   * Move definitions of CLKF_BASEPRI, CLKF_USERMODE to mips/include/cpu.
   * Delete duplicate definitions in pica/include/cpu.h, pmax/include/cpu.h.

jonathan 893a0b508b fix case typo: CLKF_BASEPRI_R4k to _R4K 1996-03-23 20:28:19 +00:00
jonathan cd58cb9caa Factor out r3000 versus r4000 differences (CLKF_USERMODE() and CLKF_BASEPRI()),
provide r3k and r4k versions of each, and move to sys/arch/mips/include.

Note in comments where each mips-based port should provide
definitions in its own cpu.h after including this file.

- remove ep_setup references.
- added struct emul to all emulations.
