Subject: [PATCH v2 0/8] Sort out SMMUv3 ATC invalidation and locking
Date: Wed, 21 Aug 2019 16:17:41 +0100 [thread overview]
Message-ID: <20190821151749.23743-1-will@kernel.org> (raw)
Hi again,
This is version two of the patches I posted yesterday:
v1: https://lkml.kernel.org/r/20190820154549.17018-1-will@kernel.org
Changes since then include:
* Fix 'ats_enabled' checking when enabling ATS
* Remove redundant 'dev_is_pci()' calls
* Remove bool bitfield
* Add patch temporarily disabling ATS detection for -stable
* Issue ATC invalidation even when non-leaf
* Elide invalidation/SYNC for zero-sized address ranges
* Shuffle the patches round a bit
Thanks,
Will
