Subject: [PATCH/RFC 03/03] iommu/ipmmu-vmsa: Add SYS-DMAC devices as whitelist
Date: Wed, 20 Dec 2017 21:24:13 +0900 [thread overview]
Message-ID: <151377265378.17613.6585544315769524309.sendpatchset@little-apple> (raw)
In-Reply-To: <151377262568.17613.8610167192375932687.sendpatchset@little-apple>
From: Magnus Damm <damm+renesas@opensource.se>
For testing purpose add a list of allowed SYS-DMAC devices to
the IPMMU driver. These may be used together with SCIF serial
ports to validate some basic operation.
