Arur" Subject: pte flags and tlb miss Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm@kvack.org List-ID: 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 ?
