| |
This patch series implements the set_dev_pasid operation for DMA and UNMANAGED iommu domains. The series depends on the CD table refactor patch series as a pre-requisite.
This patch series is also available on gerrit with Jean's SMMU test engine patches cherry-picked along with an additional set of tests for this feature: https://linux-review.googlesource.com/c/linux/kernel/git/torvalds/linux/+/24770/6
Thanks, Michael Shavit
Changes in v5: - Renamed domain_head to list for consistency with other lists - Renamed attached_domains to attached_ssids to avoid confusion. This is a list of master/ssid pairs the domain is attached to, not a list of other domains. - Fix missing error value return in set_dev_pasid - Fix issue where nr_attached_pasid_domains isn't updated when arm_smmu_write_ctx_desc fails - Fix missing free of the attached_domain node - Split off the CD table refactor to separate patch series: https://lore.kernel.org/all/20230802163328.2623773-1-mshavit@google.com/ - Link to v4: https://lore.kernel.org/all/20230621063825.268890-1-mshavit@google.com/ - New commit: Free attached pasid domains on release_device() call
Changes in v4: - Fix build warning and error on patch 07. The error was introduced during a v1->v2 rebase and hidden by patch 09 which removed the offending line. - Link to v3: https://lore.kernel.org/all/20230614154304.2860121-1-mshavit@google.com/
Changes in v3: - Dropped the bulk of the SVA refactoring to re-work as a follow-up series. - Reworded cover letter to omit dropped changes. - Rebased on 6.4 tip - Link to v2: https://lore.kernel.org/all/20230606120854.4170244-1-mshavit@google.com/
Changes in v2: - Reworded cover letter and commits based on v1 feedback. - Split and reworked `iommu/arm-smmu-v3: Move cdtable to arm_smmu_master` - Added SVA clean-up and refactor. - A few other small bug fixes and cosmetics. - Link to v1: https://lore.kernel.org/all/20230510205054.2667898-1-mshavit@google.com/
