matt 77ab725cbb Enable DOZE mode for the 604ev. 2001-11-19 23:30:07 +00:00
matt 34d4887431 Some #ifdef cleanup for DIAGNOSTIC/DEBUG/PMAPCHECK so that that many of 
the expensive checks are skipped when (!DEBUG&&!PMAPCHECK) and all of the
light-weigth checks are skipped when (!DIAGNOSTIC&&!DEBUG&&!PMAPCHECK).
This bring pmap.o's text down from 21KB (with PMAPCHECK) to 18.5KB (DEBUG)
to 16KB text (!DIAGNOSTIC).

matt ab93af26ea Fix pte_clear to TLB flush the va, not the tlb adress (which is only valid 
for clearing the ref bit).  pvo_to_pte (if !diagnostic) will return NULL
immediately if PTE_VALID is not set.

matt 1f09ca6e53 Fix a small buglet in syncicache (if the area to sync crosses the 
segment 0 boundary).

matt a696291eab Fix bug in pte_spill (wasn't searching the right pvo_table list for the 
victim PTE is the PTE was a secondary entry).

matt 4f3943d89a Test the right bit for wired in the PVO. 2001-11-05 06:24:55 +00:00
matt f02b548314 Don't try to pool_putting a PVO when re-entering a mapping. Since the 
PVO_MANAGED may get munged, we can possible put this into the wrong pool.

matt 8a49af3cec Need to use a separate variable for return value of pmap_pte_inset in 
pte_spill.  Make off the high bit of the MFTB().

matt 3ca8d91fc8 Add few a more PMAP_PVO_CHECKs in pte_spill; print pte addr of unmatched 
pte in panicstr.

thorpej 458af13ace If we get a secondary CPU on a non-MP kernel, bail out early 
and print a message about why.  This prevents the primary CPU's
cpu_info from being scribbled over w/ secondary CPU info.

chs 1661137341 it's perfectly legal for pmap_extract() on the kernel pmap to not find 
anything mapped there, even though it never used to happen.  with today's
other changes it happens a lot now, so remove the debug check for it.
 2001-09-16 05:40:46 +00:00
chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
