Hi all,

I have some questions  concerning  TLB refilling mechanism on mips:



1) In linux ,esspecially in TLB refilling,  is Context[PTEBase] used
to store cpuid? (refer to build_get_pgde32 in tlbex.c)


2) In function of build_get_ptep, when generating a   pte offset , is
Context[BadVPN]  replaceable  by BadVAddr register?


Thanks in advance
