A few months ago, I had a bit of a disaster with some pmap optimizations.
After committing, all hell broke loose. It was backed out completely.
I finally found the problem (diff cleaned up to highlight the problem):
pmap_mapdev()
...
for (tmpva = va; size > 0; ) {
pte = vtopte(tmpva);
*pte = pa | PG_RW | PG_V | pgeflag;
size -= PAGE_SIZE;
tmpva += PAGE_SIZE;
- pa += PAGE_SIZE;
}
invltlb();
Excuse me while I go outside and shoot myself.
Cheers,
-Peter
