Subject: [PATCH v5 0/3] arm64: IOMMU-backed DMA mapping
Date: Fri, 31 Jul 2015 18:18:26 +0100	[thread overview]
Message-ID: <cover.1438362603.git.robin.murphy@arm.com> (raw)

Hi all,

Here's an update following Catalin's feedback on v4[1].

Changes this round:
- Rebased onto linux-next
  - IOVA alignment fix applied already
  - iommu_iova_cache_init() is now iova_cache_get()
- Tidied up iommu_dma_alloc()
  - Simplified pgprot handling
  - Removed redundant memset
  - Skip coherent page-flushing in a simpler way
- Spotted a bug in iommu_dma_init_domain() where the checks for
  reinitialising an existing domain were backwards.

If it is going to be down to me to tackle all the driver fixes and
conversion of arch/arm dma_ops, I'd still much rather have this
code merged first as a stable base to work with (and un-block arm64
in the meantime). Have we decided yet whether this should go via the
IOMMU tree or the arm64 tree?

Thanks,
Robin.
