kleink 9133b51cd8 Replace the 'unsigned __COMPILER_INT64__' construct with a new name,
__COMPILER_UINT64__, to be supplied - if such a case is made, it shouldn't
be assumed that the unsigned type-specifier may be applied to it.

thorpej 9f5a22b3ee New syscall entry implementation based on the Alpha version
as hacked by mycroft.
- Use syscall_intern() to give a process a plain or fancy
  syscall based on ktrace flags.
- Avoid copying from the trapframe into a local array as much
  as possible.

Yields roughly 5% improvement on a 25MHz R3000 (DECstation 5000/200)
on a simple syscall benchmark.

There's still some work that can be done using __HAVE_MINIMAL_EMUL.

thorpej 61473e63f9 Define __HAVE_AST_PERPROC. 2001-01-14 22:32:57 +00:00
thorpej da57125f23 Now that we won't lose signotify()'s while we're asleep, go ahead
and to signal processing in ast() again.
2001-01-14 21:22:56 +00:00
thorpej 53d2115d66 Make the astpending flag per-process. 2001-01-14 21:18:39 +00:00
thorpej fd0ca62926 Put signal posting back in userret() for now; for it to work
properly, we need to make astpending a per-process variable.

Pointed out by mycroft.
2001-01-14 00:39:48 +00:00
thorpej 1eb36d23fd - Make ast() loop around astpending; it's possible for a new
AST to be posted when delivering signals, or after a process
  is preempted.
- Move all signal posting to ast().  userret() is now a one-liner.
2001-01-14 00:10:28 +00:00
thorpej fd0605fc53 Mmm, dependency problems. Add a cast to make PROC_PC() actually
work.
2001-01-11 21:08:18 +00:00
thorpej e292dc9609 Move userret() into a header file, in preparation for splitting
syscall() into plain and fancy.
2001-01-11 18:44:29 +00:00
thorpej f1152a965b Modeled after mycroft's changes to the Alpha port, add PROC_PC() to
get profiling out of userret(), and move the preemption check to ast().
2001-01-11 18:30:16 +00:00
simonb f514e805ed Move prototypes for mips_user_cachectl() and mips_user_cacheflush()

takemura c5fd828440 replace 'long long' with int64_t to compile stand alone program with
compiler other than GCC.

itojun efa2b7073c make mbstate_t bigger (32 -> 128 bytes).
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare).  really sorry
for the mess.
2000-12-26 10:35:28 +00:00
nisimura 752dce24ae - fix typos in mips_user_cacheflush() and mips_user_cachectl().
- relocate those function declarations from include/pmap.h.

jeffs 1c726aab7f For MIPS software masking option, when returning to user mode apply
the mask to all interrupts to catch changes in the mask state faster.
Does not affect platforms w/o this option enabled.

nisimura fdfe3556de Use only one TLB entry to wire down process's USPACE since it's
now guranteed to be aligned on 8KB boundary in kernel virutal
address.  Retain one more free TLB entry.

thorpej cb38ab39ab We use 4K pages on MIPS systems (see mips_param.h), so override
PAGE_SIZE and friends to be compile-time constants.
2000-11-14 18:55:16 +00:00
jeffs 196e858c40 Add mips_pagecopy/zero assembly loops for use by pmap_copy/zero_page*()
to allow the almost-64-bit compilation use ld/sd.
2000-10-31 23:39:24 +00:00
jeffs 11ef576801 Add mips_indexof() macro to make code for checking the cache index
easier to read.

nisimura 89e5c346a4 mips1_ConfigCache() has gone. 2000-10-09 07:33:31 +00:00
cgd 59706f1322 clean up and consistency for CP0 Count, Compare, Wired, and Config
access function names and prototypes.
2000-10-05 02:36:44 +00:00
cgd b1b364243d always have to declare cpu_arch and the related constants (since setting
it isn't conditionalized).  (d'oh!)
2000-10-05 02:13:14 +00:00
cgd 36123017cb nuke mips3_clearBEV(). There's really no point in coding a
special-purpose assembly routine for things like this.
2000-10-05 01:06:06 +00:00
cgd 3f1d3c3066 tweak cpu_arch. Eliminate all direct checks of it (making them
use the macro CPUISMIPS3 -- which is badly misnamed), and set it
from #defines named CPU_ARCH_N (where N is 1..5, 32, 64).
2000-10-05 00:52:59 +00:00
cgd e9e1084ea3 rename mips_read_causereg -> mips_cp0_cause_read. nuke prototype
for mips_read_statusreg (which was apparently never implemented).
Provide prototypes and implementations for mips_cp0_cause_write,
mips_cp0_status_read, and mips_cp0_status_write.  (Writing can, of
course, be quite dangerous.)
2000-10-04 22:44:01 +00:00
cgd 11e8e89dd4 add some additional info re: MIPS32 PRID encoding, derived from
the ``MIPS32 4K Processor Core Family Software User's Manual
Revision 01.07 June 19, 2000", available on the web from:
http://www.mips.com/declassified/Declassified_2000/MD00016-2B-4K-SUM-01.07.pdf
2000-10-03 23:15:58 +00:00
cgd 8dbc5c0c51 provide mips3_ld() and mips3_sd(), functions which provide safe wrappers
for mips3 (and later) 'ld' and 'sd' instructions.  These currently
only are properly implemented for the _MIPS_BSD_API_LP32 and
_MIPS_BSD_API_LP32_64CLEAN 'API's.  They're pretty messy, but when you
need them, you really need them.
2000-10-02 22:13:38 +00:00
thorpej b008f5f25a Make PMAP_PAGEIDLEZERO() return a boolean value. FALSE indidcates
that the page being zero'd was not completed and that page zeroing
should be aborted.  This may be used by machine-dependent code doing
slow page access to reduce the latency of running a process that has
become runnable while in the middle of doing a slow page zero.

nisimura 70a97ab16c Introduce new MIPS1 direct mapped cache capacity detection logics. 2000-09-16 07:20:16 +00:00
chuck 9dc2f5ced0 IDT32364's Config register uses a different base for IC/DC (instruction
and data cache sizes).   R4000 uses 2^(12+IC) and 2^(12+DC).  IDT32364
uses 2^(9+IC) and 2^(9+DC).

abstract around the problem by making the base a parameter to the
MIPS3_CONFIG_CACHE_SIZE macro.   we pass the base down from mips_vector_init
to mips3_vector_init and to mips3_ConfigCache (where it is used).

XXX: someone with an MIPS3_4100 should switch to this and get rid
of the ugly ifdefs in cpuregs.h

jeffs bdad8bae5b Handle R4K trap faults in user mode like overflows (deliver SIGFPE). This
prevents a panic running crashme.  Better comment for VCE define.
2000-09-15 06:50:46 +00:00
nisimura 0ba2036eee Introduce 'segbase' global variable to hold the pointer to current
process's segtab, retiring 'pcb_segtab' field from 'struct pcb'.
This would be another MULTIPROCESSOR unfriendly and the necessity
might be eliminated when the way to hold PTE is redesigned.

thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

tshiozak 51a53de0d5 Preparation for the future introduction of multibyte locale.
- MB_LEN_MAX is increased to 32.
 - To ensure binary compatibility for old executables
   under multibyte locale, versioned setlocale is added.
 - __mb_len_cur definision is added in setlocale.c
   and enable it in stdlib.h .
   It is also important for multibyte locale stuffs,
   but I just forgot.

cgd b63ed164a1 convert PRID handling to use macros on an int, not bit-fields.
there's no reason to use bit-fields, and they just complexity to
the header.
2000-07-27 17:29:05 +00:00
cgd 4adc7b9704 add nops after jals in PANIC and PRINTF. (these macros are often used in
code which has noreorder set, and they're not used with nops afterwards,
as is appropriate in that case, so put the nops in the macros.)
