There's not tonnes here, but a good mixture of optimisations and cleanups -- summary in the tag. This applies cleanly against iommu/next, but I suspect it will conflict with Robin's series on the list. Please shout if you need anything from me to help with that (e.g. rebase, checking a merge conflict). Cheers, Will --->8 The following changes since commit ff1176468d368232b684f75e82563369208bc371: Linux 5.14-rc3 (2021-07-25 15:35:14 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git tags/arm-smmu-updates for you to fetch changes up to fac956710ab0812f9e395e9f7a27da551412830f: iommu/arm-smmu-v3: Stop pre-zeroing batch commands (2021-08-13 14:26:06 +0100) ---------------------------------------------------------------- Arm SMMU updates for 5.15 - SMMUv3 * Minor optimisation to avoid zeroing struct members on CMD submission * Increased use of batched commands to reduce submission latency * Refactoring in preparation for ECMDQ support - SMMUv2 * Fix races when probing devices with identical StreamIDs * Optimise walk cache flushing for Qualcomm implementations * Allow deep sleep states for some Qualcomm SoCs with shared clocks ---------------------------------------------------------------- Ashish Mhetre (1): iommu: Fix race condition during default domain allocation John Garry (2): iommu/arm-smmu-v3: Remove some unneeded init in arm_smmu_cmdq_issue_cmdlist() iommu/arm-smmu-v3: Stop pre-zeroing batch commands Krishna Reddy (1): iommu/arm-smmu: Fix race condition during iommu_group creation Sai Prakash Ranjan (2): iommu/arm-smmu: Add clk_bulk_{prepare/unprepare} to system pm callbacks iommu/arm-smmu: Optimize ->tlb_flush_walk() for qcom implementation Zhen Lei (4): iommu/arm-smmu-v3: Use command queue batching helpers to improve performance iommu/arm-smmu-v3: Add and use static helper function arm_smmu_cmdq_issue_cmd_with_sync() iommu/arm-smmu-v3: Add and use static helper function arm_smmu_get_cmdq() iommu/arm-smmu-v3: Extract reusable function __arm_smmu_cmdq_skip_err() drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 89 +++++++++++++++++------------ drivers/iommu/arm/arm-smmu/arm-smmu-qcom.c | 11 ++++ drivers/iommu/arm/arm-smmu/arm-smmu.c | 45 ++++++++++++--- drivers/iommu/arm/arm-smmu/arm-smmu.h | 1 + drivers/iommu/iommu.c | 2 + 5 files changed, 106 insertions(+), 42 deletions(-) _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
