This series introduces support for performing iova-to-phys translations via the ARM SMMU hardware on supported implementations. We also make use of some new generic macros for polling hardware registers.
The iopoll macros were previously discussed here: http://marc.info/?l=linux-arm-kernel&m=140414727509158 Matt Wagantall (1): iopoll: Introduce memory-mapped IO polling macros Mitchel Humpherys (1): iommu/arm-smmu: add support for iova_to_phys through ATS1PR drivers/iommu/arm-smmu.c | 73 +++++++++++++++++++++++++++++- include/linux/iopoll.h | 114 +++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 186 insertions(+), 1 deletion(-) create mode 100644 include/linux/iopoll.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
