neel 2010-03-20 05:07:15 UTC FreeBSD src repository Modified files: sys/mips/include db_machdep.h trap.h sys/mips/mips db_trace.c exception.S pmap.c trap.c Log: SVN rev 205360 on 2010-03-20 05:07:15Z by neel This change enables use of physical memory that is beyond the direct mapped kseg0 region. The basic idea is to use KVA from the kseg2 region for mapping page table pages that lie beyond the direct mapped region. The TLB miss handler can now recursively fault into the TLB invalid handler if it dereferences a kseg2 page table page address that is not in the TLB.
