From 3ad6b7f3a41ba6bf4503be442802072ca9dc8336 Mon Sep 17 00:00:00 2001 From: Cho KyongHo Date: Mon, 12 May 2014 11:44:49 +0530 Subject: [PATCH] iommu/exynos: Fix L2TLB invalidation L2TLB is 8-way set-associative TLB with 512 entries. The number of sets is 64. A single 4KB(small page) translation information is cached only to a set whose index is the same with the lower 6 bits of the page frame number. A single 64KB(large page) translation information can be cached to any 16 sets whose top two bits of their indices are the same with the bit [5:4] of the page frame number. A single 1MB(section) or larger translation information can be cached to any set in the TLB. It is required to invalidate entire sets that may cache the target translation information to guarantee that the L2TLB has no stale data.
