Subject: [PATCH v3 00/25] iommu: Refactor DMA domain strictness
Date: Wed, 4 Aug 2021 18:15:28 +0100 [thread overview]
Message-ID: <cover.1628094600.git.robin.murphy@arm.com> (raw)
v1: https://lore.kernel.org/linux-iommu/cover.1626888444.git.robin.murphy@arm.com/
v2: https://lore.kernel.org/linux-iommu/cover.1627468308.git.robin.murphy@arm.com/
Hi all,
Round 3, and the patch count has crept up yet again. But the overall
diffstat is even more negative, so that's good, right? :)
Once again, to driver/platform maintainers CC'd on cookie cleanup
patches this is just a heads-up and the rest of the changes should not
affect your platforms. I hope I've now fixed the silly bug which broke
bisection between patches #1 and #12 on 32-bit Arm.
The new patches are in the middle, reworking how the SMMU drivers and
io-pgtable implement non-strict mode such that the later changes fall
into place even more easily. Turns out I didn't need the major
refactoring of io-pgtable that I had in mind, and I'm almost kicking
myself that as soon as I put the option of *not* using the existing
quirk on the table, an even cleaner and more logical solution was
staring right out at me.
Due to that signifcant change and the consequent redesign of the final
patch to make dynamic switching look viable in the face of concurrency,
I have not applied the tested-by tags from v2. They were very much
appreciated though, thanks!
Proper changelogs on the individual patches this time since otherwise
I'd have lost track...
Cheers,
Robin.
