1af95763 - iommu/amd: Initial SVA support for AMD IOMMU

Thu, 18 Apr 2024 10:33:58 +0000

iommu/amd: Initial SVA support for AMD IOMMUThis includes : - Add data structure to track per protection domain dev/pasid binding details protection_domain->dev_data_list will track attached list of dev_data/PASIDs. - Move 'to_pdomain()' to header file - Add iommu_sva_set_dev_pasid(). It will check whether PASID is supported or not. Also adds PASID to SVA protection domain list as well as to device GCR3 table. - Add iommu_ops.remove_dev_pasid support. It will unbind PASID from device. Also remove pasid data from protection domain device list. - Add IOMMU_SVA as dependency to AMD_IOMMU driverFor a given PASID, iommu_set_dev_pasid() will bind all devices to sameSVA protection domain (1 PASID : 1 SVA protection domain : N devices).This protection domain is different from device protection domain (onethat's mapped in attach_device() path). IOMMU uses domain ID for caching,invalidation, etc. In SVA mode it will use per-device-domain-ID. Hence ininvalidation path we retrieve domain ID from gcr3_info_table structure anduse that for invalidation.Co-developed-by: Wei Huang Signed-off-by: Wei Huang Co-developed-by: Suravee Suthikulpanit Signed-off-by: Suravee Suthikulpanit Signed-off-by: Vasant Hegde Reviewed-by: Jason Gunthorpe Link: https://lore.kernel.org/r/20240418103400.6229-14-vasant.hegde@amd.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/amd/Makefile

iommu/amd: Move PPR-related functions into ppr.cIn preparation to subsequent PPR-related patches, and also remove staticdeclaration for certain helper functions so that it can be reused in otherfiles.Also rename below functions: alloc_ppr_log -> amd_iommu_alloc_ppr_log iommu_enable_ppr_log -> amd_iommu_enable_ppr_log free_ppr_log -> amd_iommu_free_ppr_log iommu_poll_ppr_log -> amd_iommu_poll_ppr_logSigned-off-by: Suravee Suthikulpanit Co-developed-by: Vasant Hegde Signed-off-by: Vasant Hegde Reviewed-by: Jason Gunthorpe Link: https://lore.kernel.org/r/20240418103400.6229-5-vasant.hegde@amd.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/amd/Makefile

5a0b11a1 - iommu/amd: Remove iommu_v2 module

Fri, 06 Oct 2023 09:57:02 +0000

iommu/amd: Remove iommu_v2 moduleAMD GPU driver which was the only in-kernel user of iommu_v2 moduleremoved dependency on iommu_v2 module.Also we are working on adding SVA support in AMD IOMMU driver. Devicedrivers are expected to use common SVA framework to enable devicePASID/PRI features.Removing iommu_v2 module and then adding SVA simplifies the development.Hence remove iommu_v2 module.Cc: Alex Deucher Cc: Joerg Roedel Cc: Felix Kuehling Signed-off-by: Vasant Hegde Reviewed-by: Jason Gunthorpe Reviewed-by: Jerry Snitselaar Tested-by: Alex Deucher Link: https://lore.kernel.org/r/20231006095706.5694-2-vasant.hegde@amd.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/amd/Makefile
