Subject: [Qemu-devel] [PATCH v2 4/8] target-arm: Suppress TBI for S2 translations
Date: Sun, 13 Sep 2015 11:07:54 +0200 [thread overview]
Message-ID: <1442135278-25281-5-git-send-email-edgar.iglesias@gmail.com> (raw)
In-Reply-To: <1442135278-25281-1-git-send-email-edgar.iglesias@gmail.com>
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
Stage-2 MMU translations do not have configurable TBI as
the top byte is always 0 (48-bit IPAs).
