gwr 08f7a407f9 Separate bcopy and copypage stuff from copy.s 1997-03-17 19:46:36 +00:00
gwr 521683f862 Separate bcopy and the copypage/zeropage stuff out of copy.s
so they can be used separately, and so the copyrights are
attributed to the right owners.  (Catch-all files are bad)

thorpej f88e127939 Some misc. m68k asm support routines. This file currently contains
setjmp/longjmp and _insque/_remque.  More to come.

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

thorpej de70c1051d prototype mappedcopy{in,out}(), {copy,zero}page(). 1997-02-02 06:56:57 +00:00
thorpej 9568fcee35 Build mappedcopy.c conditional on "options MAPPEDCOPY" 1997-02-02 06:55:15 +00:00
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.

scottr 531802b5dd cpp -> ${CPP} 1996-10-29 00:11:27 +00:00
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

scottr f8b0c86aa8 The 68LC040 generates a format 4 stack frame for floating point
exceptions, which puts the address of the instruction we faulted
on in a different location.  Copy it and handle as we normally would,
restoring the saved PC before returning.

The FPE should probably be reworked to take advantage of the 68LC040's
precalculated effective address, at some point.

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.

thorpej c5e5dec3b7 All of the m68k ports' exec.h's were essentially the same. Merge them.
Override the N_PAGSIZ() macro; this one checks the MID of the executable
and returns the appropriate page size.
