thorpej 2b06ffd5f9 Add support for UVM. 1998-02-15 21:19:34 +00:00
thorpej 8559f25d47 Implement kcopy(), like bcopy(), but aborts if a fault is encountered.
Required for UVM.

mycroft b5c132e4d2 Prototype __flt_rounds() consistently. 1998-02-03 01:26:20 +00:00
is b3fa451227 Amiga uses the common m68k/sig_machdep.c now. Also moved its definition from
the other 68k ports' files.${port} to arch/m68k/conf/files.m68k.

perry 6f57e5c573 multiple include protect machine/limits.h, fixes pr 4473 (from Mika Nystrom) 1998-01-09 22:23:44 +00:00
is 5d5c1cd59e - avoid system stack underflow when calling sigreturn via trap #0
- make sure all sigreturn error conditions are reported to the caller,
  instead of the place jumped to.
This is the bugfix part of pr 4628 by ITOH Yasufumi.
The performance optimization part will be handled seperately, after evaluating
its implications.
Testing on 68040 and removing the performance change from the proposed patch
by scottr. Half of the Amiga machdep.c change had to be done manually by me,
as the patchfile didn't apply cleanly.
XXX Yes, Amiga should be changed to use the common sig_machdep.c instead.
XXX Really soon now. I promise.
1998-01-07 22:46:00 +00:00
is d002f566b3 Support 68060 (and, for the Amiga, even 68040 buserr frames) in the sendsig()
and, indirectly, sigreturn() functions.
XXX The Amiga should be switched to using sig_machdep.c instead.

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.

but he proposed a different implementation.

losing the DZ bit.
- create FPSR_OVFL and FPSR_UNFL bits in fpu_implode(). This showed up when

is f3efbb406a The recent buserr handler cleanup in the Amiga locore.s made the label

This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

jtc 9d04fc8ed1 New zeropage() implementation based on code contributed by Hiroshi Horitomo
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641.   I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes.  This
reduces the size and complexity of the function.

On the '020, the simpler code is less than 1% slower.  Surprisingly, it
is ~3% faster on the '040.

- PANIC("panic message") - shorthand for calling panic() from assembly code.
- VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries
  in the vector table.

thorpej e9eba07a8f Add the Utah mappedcopyin/mappedcopyout functions to a common m68k
area.  These functions are designed to improve performance of large
copyin/copyout operations by mapping the user page in to the kernel
address space and using bcopy(), rather then copying across protection
boundaries.

XXX This doesn't work yet -- the way it's called doesn't obey C calling
XXX conventions.  That will be fixed soon.
1997-02-02 06:54:10 +00:00
thorpej 7dae9fb29b Add two optimized functions used by pmap.c:
- copypage() -- a single page-aligned NBPG-byte copy.
- zeropage() -- a single page-aligned NBPG-byte zero.
These functions don't play around with alignment, etc.  Their use
causes a measureable performance improvement in pmap_copy_page()
and pmap_copy_page().

A few m68k ports already had copypage() in their locore.s.  It has
been moved here so it can be shared.

is be08e182af In my earlier patch to the m68k fmovem disassembler, I repaired the register
naming for fmovem, while breaking it for fmove. We probably never will
see normal fmove in the kernel, nevertheless it should be corrected while
somebody remembers.
Besides, the correct patch is smaller and thus easier to verify than the
origininal one.

is 072b7020c4 * Fix a few wrong fallthroughs in switch cases:
- add a missing return; at the end of a case, leading to wrong disassembly
  of the next few instructions after fmovem.
- while we're here, correct the same bug in PBcc.

  XXX there are a few other dubious fallthroughs in this file (which are
  not explicitly marked with /* FALLTHROUGH */), which I didn't yet analyze.

* Fix other FMOVEM interpretation bugs:
- correct printing of FP data register lists if all are used (only FP0
  would be mentioned)
- correct printing of FP data register lists in the case the list is reversed
  (would have printed nothing)
- correct mapping of fp0-fp7 to register list bits (was reversed)
- correct printing of FP control register lists (this list is never reversed)
- correct printing of FMOVEM with FP control registers (the data direction
  was interpreted the wrong way)

* While we're here, enhance the comments in MOVC's list of cpu control
  registers

ws 5804d3f648 PowerPC port 1996-09-30 16:34:14 +00:00
jtc d137b0e8ba Added new macro _PROF_PROLOG which contains the code sequence needed
to call mcount().  This is needed because the ``link a6,#0'' insn used
trips up gcc's ANSI preprocessor (A # in a function-type macro must be
followed by a macro argument).  _PROF_PROLOG is also used in the i386
asm.h.

Solaris' asm_linkage.h has a MCOUNT macro similar to _PROF_PROLOG
except it expands to different code sequences based on whether a
function is being compiled with "prof" or "gprof" instrumentation.

I also discovered that the m68k ALTENTRY is very different than the
implementation used by other NetBSD ports.  Usually ALTENTRY simply
provides an alternate function entry point.  The m68k version takes a
second argument and jumps inside the second function when profiling is
enabled.  The m68k behavior is similar to the ENTRY2 macro found in
solaris.

Providing ENTRY2 and changing all the code that uses ALTENTRY to use
it would be a desirable change.
