Subject: [Qemu-devel] [PULL v1 1/5] target-microblaze: Respect MSR.PVR as read-only
Date: Mon, 30 Apr 2018 17:08:33 +0200	[thread overview]
Message-ID: <20180430150837.20470-2-edgar.iglesias@gmail.com> (raw)
In-Reply-To: <20180430150837.20470-1-edgar.iglesias@gmail.com>

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

Respect MSR.PVR as read-only. We were wrongly overwriting the PVR bit.
