Changed name of __weak_reference() to __indr_reference(). They really

are indirect references, and I want to add a real __weak_reference()
macro to <machine/cdefs.h> soon.
1995-03-23 19:58:48 +00:00
b8403d582b
don't be so quick to cast macro arguments to unsigned; if the
...
arguments are really off_t's (e.g. to btodb), then you can lose
information. This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.
1995-03-18 07:22:43 +00:00

1995-01-25 04:18:52 +00:00
9540190d45
This file, which will be included by <sys/cdefs.h>, will contain macros
...
such as __warn_references() and __weak_reference() which are actually
machine dependant. This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.
This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.
For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
1995-01-19 01:38:36 +00:00
ecef8fddfa
Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to
...
more closely match the 386 manual. (Probably the mnemonics should be changed,

1994-11-08 23:09:21 +00:00
205d425f2f
As pointed out by Bruce, splsoftclock() needs to process pending interrupts
...
when lowering the priority. Do this by simply calling splx(). For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does. This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.
1994-11-06 01:37:47 +00:00
c2191a2ad0
Fully prototype ssdtosd() and sdtossd().
1994-11-05 03:20:36 +00:00

Only use ssdtosd() when creating, expanding, or copying the LDT. Keep a copy

Updated bde's comments wrt. i387 control word settings so that they
...
describe NetBSD, rather than 386BSD 0.1.
Removed 386BSD and BDE control word constants, since we don't need and
will never use them. However, The iBCS control word constant is kept,
since we might want to use it in the iBCS binary compatibility code.

4116a4243e
Various changes:
...
* Inline some functions.
* Eliminate redundant calls to pmap_page_index().
* Reduce the number of TLB flushes in accordance with the i386 SSWG.
* Inline pmap_remove() in pmap_remove_all(). (Most if it is unnecessary.)
* Allocate pv_entry's in pages, and keep a list of free entries in each page,
and a list of pages with free entries. (Trying to reduce malloc() overhead,
and improve locality of reference.)
* Remove a couple of macros that aren't really useful.
* Remove pmap_kernel() completely.
1994-09-07 20:48:52 +00:00

architectures:
Renamed _C_FUNC() to _C_LABEL()
Renamed _ASM_FUNC() to _ASM_LABEL()
Merged _BEGIN_ENTRY with _ENTRY
Renamed _END_ENTRY to _PROF_PROLOGUE
When assembling with profiling enabled, set up stack frame before calling
mcount() in _PROF_PROLOGUE. Also omit emitting .long 0's, as they are no
longer used by the profiling code.

Mostly stylistic change.

lots of changes: prototype migration, move lots of variables, definitions,
...
and structure elements around. kill some unnecessary type and macro
definitions. standardize clock handling. More changes than you'd want.

Rename a lot of process flags.

Only #include other stuff #ifdef KERNEL.

Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls.
...
Reorganize and clean up the relevant code.

Inline assembly [hn]to[nh][sl] functions used xchgb %h1,%b1 instead of the
...
faster (on the i486 & i586) rorw $8, %w1. The inline assembly for GCC 1.X
already used rorw. Using rorw is one byte longer, but we wouldn't be
inlining at all if we weren't optimizing for speed.

add basic integral types (a la sparc port) that new nvi wants.
