chs 8677b0ddf4 rearrange pmap_kenter_pa() to map unmanaged pages uncached as well.
this is apparently needed on the arc port.
slight optimization in pmap_kremove().

simonb 02f580ae38 Fix lint problem introduced in last change - if `lint' is defined,
#define away __alignof__.  Still produces some warnings, but at least
they're not fatal anymore.

Problem noted by Rafal Boni in private mail.

mips3, mips32 and mips64).

simonb dd6c57e790 Fix for single-byte mbufs. 2001-08-17 07:21:07 +00:00
simonb b2b2f7ccfa Fix va_arg() problem when adjusting argument pointer when a structure is
passed which is larger than an int but has int alignment.  As well as
fixing the described problem, this is the same way it is handled in the
Irix and Ultrix header files.

Problem and suggested solution by Uros Prestor in port-mips mailling
list.

chs be706f969f in vunmapbuf(), call pmap_remove() explicitly since uvm_km_free_wakeup()
will soon no longer do it for us.

chs f6a81a1ac7 remove the uncached idle-loop page zeroing.
(to be replaced by a version that uses the cache...)
2001-08-04 04:26:48 +00:00
chs 873e926c7b remove remaining spl calls, they're not needed.
remove some checks for impossible conditions.
in pmap_enter(), only call pmap_remove() to remove an existing mapping
if there actually is an existing mapping.

in pmap_remove_pv(), don't flush the MIPS1 cache when removing the last mapping.
this was added in rev 1.97, to avoid stale data being left in the cache
when the page is zeroed bypassing the cache in pmap_zero_page_uncached().
we've since found that bypassing the cache for idle-loop page zeroing
doesn't work very well anyway, so we don't do that anymore.
so now we can remove the extra cache-flush.
remove pmap_zero_page_uncached() while I'm thinking of it.

various other cleanup.

chs e2de9310c3 fix pmap_extract() to handle unmapped kernel addresses. 2001-07-28 17:18:59 +00:00
rafal e9ad38e77d Fix bug in mips3_proc_trampoline: SR wasn't disabled on entry, allowing an
interrupt to sneak in after EXL had been set; the interrupt EPC was stale
as PC isn't saved if EXL is set, causing the eret to return to the wrong
place and leading to kernel-mode TLB misses on user addresses.  The bug
was discovered by the japanese NetBSD/*mips folks and the same fix was
found independently by shinohara-san (shin@netbsd.org).

oster fd5247de51 By adding a well-placed space or two, 'make depend' no longer loses
due to a directory name like 'arc.current' messing up a sed substitution.

thorpej 93c03c9726 - Implement a real pmap_kenter_pa()/pmap_kremove().
- Use pools for pmap structures and pv_entry structures.
- Remove a bunch of splvm()/splx(), no longer needed now that
  pmap_kenter_pa() and pmap_kremove() are as they should be.

Mostly from Chuck Silvers.

thorpej 8eb3b954f1 Don't need to prototype child_return() here, it's in <sys/proc.h>. 2001-06-14 22:56:55 +00:00
thorpej ba52d7a5d0 Always indirect through the "locoresw" to get the cache ops, since
there are just far too many combinations to handle with magic
#ifdefs in any sane way.  Also, add a HitFlushDCache op to the
"locoresw", and fill it in as appropriate (it's NULL on MIPS-I,
so watch out).

These changes ensure that my R4600 Indy (with 2-way cache) gets
the correct cache ops when the kernel is built with only MIPS3
support, resulting in a kernel that is significantly more stable.

soda 9bac50748f "opt_ddb.h" should be included at the beginning of source file,
because some headers (in this case <systm.h>) refers symbols (e.g. DDB)

nisimura c227148511 PRiD 0x18 is shared by RC32334, 332 and 355. These SoCs are
distinguished by SYSID register in the system controller.  Note
that PRiD 0x20 is for a standalone RC32364 processor which has the
same 32300 core inside.  Rather better to name them MIPS32 ISA.

hubertf 9422f74ca8 Allow overriding the 'install' target.
(I have a nice 'install' target for cobalts here, but that only works there.
 I guess I'll put that into htdocs now that the cobalt port uses Makefile.mips)
