Subject: [PATCH v12 00/10] iommu: I/O page faults for SMMUv3
Date: Wed, 27 Jan 2021 16:43:13 +0100 [thread overview]
Message-ID: <20210127154322.3959196-1-jean-philippe@linaro.org> (raw)
Add stall support to the SMMUv3, along with a common I/O Page Fault
handler.
Since v11 I added a sanity check in arm_smmu_dev_disable_feature(),
patch 10: return -EBUSY if device drivers attempt to disable the IOPF
feature before SVA. That would leak the IOPF param and fault handler.
v11: https://lore.kernel.org/linux-iommu/20210125110650.3232195-1-jean-philippe@linaro.org/
v10: https://lore.kernel.org/linux-iommu/20210121123623.2060416-1-jean-philippe@linaro.org/
v9: https://lore.kernel.org/linux-iommu/20210108145217.2254447-1-jean-philippe@linaro.org/
