Subject: [Qemu-devel] [RFC PATCH 10/11] Make flatview_do_translate() take a MemTxAttrs argument
Date: Mon, 30 Apr 2018 19:19:04 +0100	[thread overview]
Message-ID: <20180430181905.32327-11-peter.maydell@linaro.org> (raw)
In-Reply-To: <20180430181905.32327-1-peter.maydell@linaro.org>

As part of plumbing MemTxAttrs down to the IOMMU translate method,
add MemTxAttrs as an argument to flatview_do_translate().
