[07/17][PATCH] kvm/ia64: Add TLB virtulization support.-V8
...ao,
Just a clarification question on this one:
> +void machine_tlb_purge(u64 va, u64 ps)
> +{
> + ia64_ptcl(va, ps << 2);
> +}
What is the purpose of machine_tlb_purge()? Is it supposed to do a
global purge of the tlb on the host machine? If so, how does this macro
differ from platform_global_tlb_purge()?
I am mentioning this because it's very important to keep in mind that
the regular tlb purging instructions are not functional on all ia64
platforms, which is why we have special implementations via the
machine vector interface.
Cheers,
Jes
