Subject: [PATCH v2 22/40] iommu/arm-smmu-v3: Add second level of context descriptor table
Date: Fri, 11 May 2018 20:06:23 +0100 [thread overview]
Message-ID: <20180511190641.23008-23-jean-philippe.brucker@arm.com> (raw)
In-Reply-To: <20180511190641.23008-1-jean-philippe.brucker-5wv7dgnIgG8@public.gmane.org>
The SMMU can support up to 20 bits of SSID. Add a second level of page
tables to accommodate this. Devices that support more than 1024 SSIDs now
have a table of 1024 L1 entries (8kB), pointing to tables of 1024 context
descriptors (64kB), allocated on demand.
