eb947d2f5e Fix bug in event signalling. 1999-06-01 09:34:06 +00:00

6e95146ec6 Raise spl4 to spl6 in quick_go--I am now experimenting with interrupts 
at levels 5 (sound) and 6 (via1) on the Q700.
Raise splhigh when reading and writing registers.  It's ugly, but it's
possible that we could get an interrupt from a higher-level source,
causing a re-read of a memory location.
This is not good when, e.g., we are reading the interrupt register.
Ideally, we would just raise splhigh() in ncr53c9x_readregs(), but
that's m.i. code, and it may be expensive on other architectures.

42d2797a4b Comment out DISABLE_EXT_CACHE as it unnecessarily slows down the IIci 
w/ external cache.  Leave it around so the paranoid can still use it.

db782f7c11 First attempt to implement PMAP_NEW interface. 
The code was mostly written before the pmap_k* inconsistency fixes.
Work around might still remain.  Should be removed.

59422960ea PR 7220 from Ken Nakata: 
I've fixed most (not all) m68k FPE bugs that give bogus
calculation results, esp. fsqrt instruction.  Also, the internal FP
representation has been reduced from 115-bit mantissa to 67-bit
mantissa which reduced the required mantissa operation roughly by one
fourth.  I've done an extensive (though not exhaustive - it's
impossible!) test on the internal routines by feeding them randomly
generated FP numbers, and found that the new code is more precise than
MC68040 FPU (it seems to have a rounding bug).

[ Only change was to keep fpu_calcea.c's name instead of renaming to
  fpu_ea.c in Ken's patch.  --akb ]

de1ba9c829 Grab real locks from the sparc port. I suppose we could use casa and casx 
instead of ldstub, but since we aren't doing n-way locking it makes little
difference.  N.B. Need to decide what to do with sparc64/sparc64/asm.h which
has name conflicts with sparc64/include/asm.h.  So far most of
sparc64/sparc64/asm.h has been moved to ctlreg.h.

ce19767c8b - Make a modification to reduce the cost of TLBmod exception handling. 
TLBUpdate() routine is used for dual purposes.  In TLBmod case, just ok
to call 'tlbwi' (as designed).  Result in saving of extraneous execution
path.  MIPS1 only this moment.

2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which 
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.
