Subject: [PATCH v2 00/24] iommu: Refactor DMA domain strictness
Date: Wed, 28 Jul 2021 16:58:21 +0100	[thread overview]
Message-ID: <cover.1627468308.git.robin.murphy@arm.com> (raw)

Hi all,

Here's v2 where things start to look more realistic, hence the expanded
CC list. The patches are now based on the current iommu/core branch to
take John's iommu_set_dma_strict() cleanup into account.

The series remiains in two (or possibly 3) logical parts - for people
CC'd on cookie cleanup patches, the later parts should not affect you
since your drivers don't implement non-strict mode anyway; the cleanup
is all pretty straightforward, but please do yell at me if I've managed
to let a silly mistake slip through and broken your driver.

This time I have also build-tested x86 as well as arm64 :)

Changes in v2:

- Add iommu_is_dma_domain() helper to abstract flag check (and help
  avoid silly typos like the one in v1).
- Tweak a few commit messages for spelling and (hopefully) clarity.
- Move the iommu_create_device_direct_mappings() update to patch #14
  where it should have been.
- Rewrite patch #20 as a conversion of the now-existing option.
- Clean up the ops->flush_iotlb_all check which is also made redundant
  by the new domain type
- Add patch #24, which is arguably tangential, but it was something I
  spotted during the rebase, so...

Once again, the whole lot is available on a branch here:

https://gitlab.arm.com/linux-arm/linux-rm/-/tree/iommu/fq

Thanks,
Robin.
