2015-02-12Merge tag 'iommu-updates-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommuLinus Torvalds1-1/+1
Pull IOMMU updates from Joerg Roedel: "This time with: - Generic page-table framework for ARM IOMMUs using the LPAE page-table format, ARM-SMMU and Renesas IPMMU make use of it already. - Break out the IO virtual address allocator from the Intel IOMMU so that it can be used by other DMA-API implementations too. The first user will be the ARM64 common DMA-API implementation for IOMMUs - Device tree support for Renesas IPMMU - Various fixes and cleanups all over the place" * tag 'iommu-updates-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (36 commits) iommu/amd: Convert non-returned local variable to boolean when relevant iommu: Update my email address iommu/amd: Use wait_event in put_pasid_state_wait iommu/amd: Fix amd_iommu_free_device() iommu/arm-smmu: Avoid build warning iommu/fsl: Various cleanups iommu/fsl: Use %pa to print phys_addr_t iommu/omap: Print phys_addr_t using %pa iommu: Make more drivers depend on COMPILE_TEST iommu/ipmmu-vmsa: Fix IOMMU lookup when multiple IOMMUs are registered iommu: Disable on !MMU builds iommu/fsl: Remove unused fsl_of_pamu_ids[] iommu/fsl: Fix section mismatch iommu/ipmmu-vmsa: Use the ARM LPAE page table allocator iommu: Fix trace_map() to report original iova and original size iommu/arm-smmu: add support for iova_to_phys through ATS1PR iopoll: Introduce memory-mapped IO polling macros iommu/arm-smmu: don't touch the secure STLBIALL register iommu/arm-smmu: make use of generic LPAE allocator iommu: io-pgtable-arm: add non-secure quirk ...
2015-02-04iommu: Update my email addressJoerg Roedel1-1/+1
The AMD address is dead for a long time already, replace it with a working one. Signed-off-by: Joerg Roedel <jroedel@suse.de>
2015-01-15iommu/irq_remapping: Kill function irq_remapping_supported() and related codeJiang Liu1-1/+0
Simplify irq_remapping code by killing irq_remapping_supported() and related interfaces. Joerg posted a similar patch at https://lkml.org/lkml/2014/12/15/490, so assume an signed-off from Joerg.

2013-06-19perf/x86/amd: Add IOMMU Performance Counter resource managementSteven L Kinney1-0/+7
Add functionality to check the availability of the AMD IOMMU Performance Counters and export this functionality to other core drivers, such as in this case, a perf AMD IOMMU PMU. This feature is not bound to any specific AMD family/model other than the presence of the IOMMU with P-C enabled. The AMD IOMMU P-C support static counting only at this time.

2012-09-28iommu/amd: Add initialization routines for AMD interrupt remappingJoerg Roedel1-0/+8
Add the six routines required to setup interrupt remapping with the AMD IOMMU. Also put it all together into the AMD specific irq_remap_ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add function to get IOMMUv2 domain for pdevJoerg Roedel1-0/+1
The AMD IOMMUv2 driver needs to get the IOMMUv2 domain associated with a particular device. This patch adds a function to get this information. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement function to send PPR completionsJoerg Roedel1-0/+6
To send completions for PPR requests this patch adds a function which can be used by the IOMMUv2 driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement functions to manage GCR3 tableJoerg Roedel1-0/+4
This patch adds functions necessary to set and clear the GCR3 values associated with a particular PASID in an IOMMUv2 domain. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement IOMMUv2 TLB flushing routinesJoerg Roedel1-0/+3
The functions added with this patch allow to manage the IOMMU and the device TLBs for all devices in an IOMMUv2 domain. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add support for IOMMUv2 domain modeJoerg Roedel1-0/+1
This patch adds support for protection domains that implement two-level paging for devices. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add amd_iommu_domain_direct_map functionJoerg Roedel1-0/+3
This function can be used to switch a domain into paging-mode 0. In this mode all devices can access physical system memory directly without any remapping. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement notifier for PPR faultsJoerg Roedel1-0/+3

2011-12-12iommu/amd: Add iommuv2 flag to struct amd_iommuJoerg Roedel1-0/+3
In mixed IOMMU setups this flag inidicates whether an IOMMU supports the v2 features or not. This patch also adds a global flag together with a function to query that flag from other code. The flag shows if at least one IOMMUv2 is in the system. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
