hello all,
i am reading kvm code and confused about the mmu_pte_write process,
when update a gpte, function kvm_mmu_pte_write is called , and walk the shadow page for it.why condition is :
if (sp->gfn != gfn || sp->role.direct || sp->role.invalid)
continue;
and not update those sp->gfn == gfn && sp->role.direct,what does it mean when role.direct is clear?
thanks.
