Subject: duplicate tlb entries
Date: Mon, 21 May 2007 18:16:31 -0400 [thread overview]
Message-ID: <46521A3F.6060107@sneakemail.com> (raw)
Hello,
Could anyone tell me if the following dump_tlb_all() is valid? I see a
few duplicate tlb entries, which I'm under the impression is not a good
thing. Unfortunately, I haven't been able to figure it out from my
investigating. I'm using a Mips32/r4000-style TLB setup with 2.6.16.18.
I did the dump below during a squashfs error I was experiencing.
Also please note I commented out
if ((entryhi & 0xf0000000) != 0x80000000
&& (entryhi & 0xff) == asid) {
which normally suppresses some of the output so every tlb entry would be
dumped.
Heres dump_tlb_all() output slightly modified and sorted on va for
readability.
