Subject: [PATCH v14 00/13] SMMUv3 Nested Stage Setup (IOMMU part)
Date: Tue, 23 Feb 2021 21:56:21 +0100 [thread overview]
Message-ID: <20210223205634.604221-1-eric.auger@redhat.com> (raw)
This series brings the IOMMU part of HW nested paging support
in the SMMUv3. The VFIO part is submitted separately.
This is based on Jean-Philippe's
[PATCH v12 00/10] iommu: I/O page faults for SMMUv3
https://lore.kernel.org/linux-arm-kernel/YBfij71tyYvh8LhB@myrica/T/
The IOMMU API is extended to support 2 new API functionalities:
1) pass the guest stage 1 configuration
2) pass stage 1 MSI bindings
Then those capabilities gets implemented in the SMMUv3 driver.
The virtualizer passes information through the VFIO user API
which cascades them to the iommu subsystem. This allows the guest
to own stage 1 tables and context descriptors (so-called PASID
table) while the host owns stage 2 tables and main configuration
structures (STE).
Best Regards
Eric
This series can be found at:
https://github.com/eauger/linux/tree/v5.11-stallv12-2stage-v14
(including the VFIO part in its last version: v12)
The VFIO series is sent separately.
History:
Previous version (v13):
https://github.com/eauger/linux/tree/5.10-rc4-2stage-v13
v13 -> v14:
- Took into account all received comments I think. Great
thanks to all the testers for their effort and sometimes
fixes. I am really grateful to you!
- numerous fixes including guest running in
noiommu, iommu.strict=0, iommu.passthrough=on,
enable_unsafe_noiommu_mode
v12 -> v13:
- fixed compilation issue with CONFIG_ARM_SMMU_V3_SVA
reported by Shameer. This urged me to revisit patch 4 into
iommu/smmuv3: Allow s1 and s2 configs to coexist where
s1_cfg and s2_cfg are not dynamically allocated anymore.
Instead I use a new set field in existing structs
- fixed 2 others config checks
- Updated "iommu/arm-smmu-v3: Maintain a SID->device structure"
according to the last version
v11 -> v12:
- rebase on top of v5.10-rc4
Eric Auger (13):
iommu: Introduce attach/detach_pasid_table API
iommu: Introduce bind/unbind_guest_msi
iommu/smmuv3: Allow s1 and s2 configs to coexist
iommu/smmuv3: Get prepared for nested stage support
iommu/smmuv3: Implement attach/detach_pasid_table
iommu/smmuv3: Allow stage 1 invalidation with unmanaged ASIDs
iommu/smmuv3: Implement cache_invalidate
dma-iommu: Implement NESTED_MSI cookie
iommu/smmuv3: Nested mode single MSI doorbell per domain enforcement
iommu/smmuv3: Enforce incompatibility between nested mode and HW MSI
regions
iommu/smmuv3: Implement bind/unbind_guest_msi
iommu/smmuv3: report additional recoverable faults
iommu/smmuv3: Accept configs with more than one context descriptor
