Subject: [PATCH v10 0/3] Enhance IOMMU default DMA mode build options
Date: Thu, 3 Jun 2021 21:58:32 +0800	[thread overview]
Message-ID: <1622728715-209296-1-git-send-email-john.garry@huawei.com> (raw)

This is a reboot of Zhen Lei's series from a couple of years ago, which
never made it across the line.

I still think that it has some value, so taking up the mantle.

Motivation:
Allow lazy mode be default mode for DMA domains for all ARCHs, and not
only those who hardcode it (to be lazy). For ARM64, currently we must use
a kernel command line parameter to use lazy mode, which is less than
ideal.

Differences to v9:
https://lore.kernel.org/linux-iommu/20190613084240.16768-1-thunder.leizhen@huawei.com/#t
- Rebase to v5.13-rc2
- Remove CONFIG_IOMMU_DEFAULT_PASSTHROUGH from choice:
  Since we can dynamically change default domain of group, lazy or strict and
  passthrough are not mutually exclusive
- Drop ia64 patch, which I don't think was ever required
- Drop "x86/dma: use IS_ENABLED() to simplify the code", which is no
  longer required
- Drop s390/pci patch, as this arch does not use CONFIG_IOMMU_API or even
  already honour CONFIG_IOMMU_DEFAULT_PASSTHROUGH
  https://lore.kernel.org/linux-iommu/20190613084240.16768-4-thunder.leizhen@huawei.com/
- Drop powernv/iommu patch, as I no longer think that it is relevant
  https://lore.kernel.org/linux-iommu/20190613084240.16768-5-thunder.leizhen@huawei.com/
- Some tidying
