Subject: [PATCH v3 0/8] iommu/arm-smmu: Support maintaining bootloader mappings
Date: Fri,  4 Sep 2020 15:55:05 +0000	[thread overview]
Message-ID: <20200904155513.282067-1-bjorn.andersson@linaro.org> (raw)

Based on previous attempts and discussions this is the latest attempt at
inheriting stream mappings set up by the bootloader, for e.g. boot splash or
efifb.

Per Will's request this builds on the work by Jordan and Rob for the Adreno
SMMU support. It applies cleanly ontop of v16 of their series, which can be
found at

Bjorn Andersson (8):
  iommu/arm-smmu: Refactor context bank allocation
  iommu/arm-smmu: Delay modifying domain during init
  iommu/arm-smmu: Consult context bank allocator for identify domains
  iommu/arm-smmu-qcom: Emulate bypass by using context banks
  iommu/arm-smmu-qcom: Consistently initialize stream mappings
  iommu/arm-smmu: Add impl hook for inherit boot mappings
  iommu/arm-smmu: Provide helper for allocating identity domain
  iommu/arm-smmu-qcom: Setup identity domain for boot mappings
