I am just trying to understand how pte flags work. I see that the pte_mkyoung()
is called whenever a pte entry
is created. In i-386 it happens only in handle_pte_fault which is called
during a page fault. My question is will this flag be updated during every
page fault and every tlb miss.
When is pte_mkyoung() called ?
One more question is, how are tlb misses handled in linux. Are they
considered as minor faults and handled by do_page_fault() itself or is
there any other function that handles this ?
Thanks,
Raghu
