[PATCH v3 0/7] Some vIOMMU fixes


From: Eric Auger
Subject: [PATCH v3 0/7] Some vIOMMU fixes
Date: Tue, 9 Mar 2021 11:27:35 +0100

Hi,

Here is a set of vIOMMU fixes:

SMMUv3:
- top SID computation overflow when handling SMMU_CMD_CFGI_ALL
- internal IOTLB handling (changes related to range invalidation)
  - smmu_iotlb_inv_iova with asid = -1
  - non power of 2 invalidation range handling.

VIRTIO-IOMMU:
  - non power of 2 invalidation range handling.

Best Regards

Eric

v3: https://github.com/eauger/qemu/tree/viommu_fixes_for_6-v3
v2: https://github.com/eauger/qemu/tree/viommu_fixes_for_6-v2

History:
v2 -> v3:
- Collected R-b's
- Added doc-comment for dma_aligned_pow2_mask()
- Up to now I have kept a single TTL check to avoid the
  remove-by-key path in smmu_iotlb_inv_iova (not checking TG)

v1 -> v2:
- new:
  - dma: Introduce dma_aligned_pow2_mask()
  - intel_iommu: Fix mask may be uninitialized in vtd_context_device_invalidate
  - hw/arm/smmuv3: Uniformize sid traces
