Subject: [PATCH 0/1] Implement flush_kern_tlb_page
Date: Mon, 19 May 2014 16:04:24 +0530 [thread overview]
Message-ID: <1400495665-48279-1-git-send-email-ritesh.harjani@gmail.com> (raw)
From: Ritesh Harjani <ritesh.harjani@gmail.com>
This patch adds the function definition to
flush_kern_tlb_page, defined in comments header in
arch/arm64/include/asm/tlbflush.h
>From ARMv8_arm:
TLBI VAE1IS: Global TLB entries that match the VA value will be affected by this operation,
regardless of the value of the ASID field.
So, since kernel region has nG(non-Global) == 0, means region is available for
all processes. So, we can use TLBI VAE1IS for kernel region as well.
