Subject: [PATCH v2 0/2] iommu/arm-smmu-v3: Fix SVA vs. HAFT issues
Date: Thu, 23 Jul 2026 15:19:42 +0100 [thread overview]
Message-ID: <cover.1784814923.git.robin.murphy@arm.com> (raw)
v1: https://lore.kernel.org/all/878cd6bcbbe2d5677d2f63da13294c148268552c.1782927917.git.robin.murphy@arm.com/
Per the discussion on v1, the aim here is just to make things safe and
functionally correct for now, and now with a command-line option for
distro users to get themselves out of a corner if they really need to,
I think that's reasonable enough for HAFT being a very new feature.
Thanks,
Robin.
