Subject: [PATCH RESEND v10 0/4] iommu: Shared Virtual Addressing for SMMUv3 (PT sharing part)
Date: Fri, 6 Nov 2020 16:50:46 +0100 [thread overview]
Message-ID: <20201106155048.997886-1-jean-philippe@linaro.org> (raw)
These are the remaining bits implementing iommu_sva_bind_device() for
SMMUv3. They didn't make it into v5.10 because an Ack was missing for
adding the PASID field to mm_struct. That is now upstream, in commit
52ad9bc64c74 ("mm: Add a pasid member to struct mm_struct"). No change
since last posting [1], only rebased onto v5.10-rc2.
Note that full SVA support for SMMUv3 still needs IOPF and DVM support,
coming soon.
