Subject: [PULL 08/27] hvf: Add execute to dirty log permission bitmap
Date: Mon, 20 Sep 2021 15:19:28 +0100	[thread overview]
Message-ID: <20210920141947.5537-9-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210920141947.5537-1-peter.maydell@linaro.org>

From: Alexander Graf <agraf@csgraf.de>

Hvf's permission bitmap during and after dirty logging does not include
the HV_MEMORY_EXEC permission. At least on Apple Silicon, this leads to
instruction faults once dirty logging was enabled.

Add the bit to make it work properly.
