Subject: [PATCH v2 0/6] Add support for QCOM IOMMU v2 and 500
Date: Fri, 27 Sep 2019 11:09:41 +0200 [thread overview]
Message-ID: <20190927090947.11175-1-kholk11@gmail.com> (raw)
From: AngeloGioacchino Del Regno <kholk11@gmail.com>
Some Qualcomm Family-B SoCs have got a different version of the QCOM
IOMMU, specifically v2 and 500, which perfectly adhere to the current
qcom_iommu driver, but need some variations due to slightly different
hypervisor behavior.
The personal aim is to upstream MSM8956 as much as possible.
This code has been tested on two Sony phones featuring the Qualcomm
MSM8956 SoC.
Changes in v2:
- Fixed optional properties placement in documentation
AngeloGioacchino Del Regno (6):
iommu/qcom: Use the asid read from device-tree if specified
iommu/qcom: Write TCR before TTBRs to fix ASID access behavior
iommu/qcom: Properly reset the IOMMU context
iommu/qcom: Add support for AArch64 IOMMU pagetables
iommu/qcom: Index contexts by asid number to allow asid 0
iommu/qcom: Add support for QCIOMMUv2 and QCIOMMU-500 secured contexts
