mrg 7b93dd1117 remove opt_uvm.h 1999-03-25 00:41:46 +00:00
drochner 88a179595a regdef.h is back 1999-03-24 21:15:17 +00:00
mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

nisimura f719570f0a - Restore 'regdef.h' lost since last January. 1999-03-24 03:45:36 +00:00
simonb aca34380db If on entry the stack is within 4kB of _start, don't reset the stack
pointer to just underneath _start.  Allows bootblocks (or other kernel
calling programs) to pass more than 4 arguments if it sets up the stack
properly.

The 4kB figure may be overkill - on the pmax it only needs to be a dozen
of so bytes.

nisimura 17e168c9b3 - Nuke old leftover; round four. This file has little usefuls, and
target MIPS ports are expected to have 'machine/conf.h' if necessary.

mhitch 263d2c47a5 Read-only unnmanaged pages on MIPS3 need the RO attribute bit, otherwise the
tlbmod exception panics.  This appears to have been incorrect even in the pica
pmap.c, which I pulled in for the pmax.  Fixes Xcfbpmax crashes on R40x0
systems with sfb framebuffer.

Fix resident_count tracking so it doesn't go negative.  UVM will change a
page mapping without removing the original mapping.  That was causing a
problem early on when getting UVM working on the mips, and the explicit
pmap_remove() done by pmap_enter() was decrementing the resident_count.
Do the pmap_remove() first, then check if the current mapping is not valid
and increment the resident_count.

mhitch 12ec406bcf Remove a couple of 'XXX MIPS3?' comments in the tlbmod exeception handling -

mhitch cb8e3b18a7 Change switch_exit() to use the *current* proc0 stack pointer, instead of
the *initial* stack pointer.  The proc0 stack is being used by proc0 (i.e.
uvm_scheduler).  This had been working because switch_exit() wasn't
overwriting any critical areas of the stack - unless kernel profiling
was turned on.

mhitch ae4fe46357 Fix the TLBMiss handler to not use an undefined operation (32 bit operation
on 64 bit register that's not correctly signed extended.  The R4x00 support
works again on DECstations.  A similar change to the XTLBMiss handler probably
needs to be made, but I have not done that since I am unable to test any
changes to that.
Also re-order a couple of instructions to allow for delay with mfc0.
