Modified files:
sys/sparc64/include pmap.h tlb.h
sys/sparc64/sparc64 cache.c cheetah.c machdep.c pmap.c
spitfire.c swtch.S tlb.c
Log:
- Move the routine for flushing all user mappings from the tlb from pmap to
the cpu dependent files. It will need to be done differently for USIII.
- Simplify the logic for detecting context rollovers. Instead of dealing
with it when the next context switch would cause the context numbers to
rollover, deal with it when they actually do rollover.
- Move some things around in cpu_switch so that we only do 1 membar #Sync
when switching address space, instead of 2.
- Detect kernel threads by comparing the new vm space to vmspace0, instead
if checking if the tlb context is 0.
- Removed some debug code.
