Subject: [PATCH 0/5] io-pgtable fixes + ARM short-descriptor format
Date: Fri, 4 Dec 2015 17:52:57 +0000 [thread overview]
Message-ID: <cover.1449246988.git.robin.murphy@arm.com> (raw)
This has been tested on an MMU-500 Fast Model, with the ARM SMMU driver
hacked up to force short-descriptor at stage 1 - doing it properly needs
more work to decouple the context format from the kernel bit-ness. Since
I didn't want to delay getting this lot posted, that can come later.
Thanks,
Robin.
