5c0ebbd3 - iommu/riscv: Add RISC-V IOMMU platform device driver

Wed, 16 Oct 2024 06:52:14 +0000

iommu/riscv: Add RISC-V IOMMU platform device driverIntroduce platform device driver for implementation of RISC-V IOMMUarchitected hardware.Hardware interface definition located in file iommu-bits.h is based onratified RISC-V IOMMU Architecture Specification version 1.0.0.This patch implements platform device initialization, early check andconfiguration of the IOMMU interfaces and enables global pass-throughaddress translation mode (iommu_mode == BARE), without registeringhardware instance in the IOMMU subsystem.Link: https://github.com/riscv-non-isa/riscv-iommuCo-developed-by: Nick Kossifidis Signed-off-by: Nick Kossifidis Co-developed-by: Sebastien Boeuf Signed-off-by: Sebastien Boeuf Reviewed-by: Lu Baolu Signed-off-by: Tomasz Jeznach Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/2f2e4530c0ee4a81385efa90f1da932f5179f3fb.1729059707.git.tjeznach@rivosinc.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/Makefile

c4629449 - iommu/tegra-gart: Remove tegra-gart

Wed, 13 Sep 2023 13:43:39 +0000

iommu/tegra-gart: Remove tegra-gartThierry says this is not used anymore, and doesn't think it makes sense asan iommu driver. The HW it supports is about 10 years old now and newer HWuses different IOMMU drivers.As this is the only driver with a GART approach, and it doesn't reallymeet the driver expectations from the IOMMU core, let's just remove itso we don't have to think about how to make it fit in.It has a number of identified problems: - The assignment of iommu_groups doesn't match the HW behavior - It claims to have an UNMANAGED domain but it is really an IDENTITY domain with a translation aperture. This is inconsistent with the core expectation for security sensitive operations - It doesn't implement a SW page table under struct iommu_domain so * It can't accept a map until the domain is attached * It forgets about all maps after the domain is detached * It doesn't clear the HW of maps once the domain is detached (made worse by having the wrong groups)Cc: Thierry Reding Cc: Dmitry Osipenko Acked-by: Thierry Reding Reviewed-by: Lu Baolu Reviewed-by: Jerry Snitselaar Signed-off-by: Jason Gunthorpe Link: https://lore.kernel.org/r/6-v8-81230027b2fa+9d-iommu_all_defdom_jgg@nvidia.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/Makefile

745ef109 - iommu/io-pgtable: Move Apple DART support to its own file

Fri, 16 Sep 2022 09:41:49 +0000

iommu/io-pgtable: Move Apple DART support to its own fileThe pte format used by the DARTs found in the Apple M1 (t8103) is notfully compatible with io-pgtable-arm. The 24 MSB are used for subpageprotection (mapping only parts of page) and conflict with the addressmask. In addition bit 1 is not available for tagging entries but disablessubpage protection. Subpage protection could be useful to support a CPUgranule of 4k with the fixed IOMMU page size of 16k.The DARTs found on Apple M1 Pro/Max/Ultra use another different pteformat which is even less compatible. To support an output address sizeof 42 bit the address is shifted down by 4. Subpage protection ismandatory and bit 1 signifies uncached mappings used by the displaycontroller.It would be advantageous to share code for all known Apple DARTvariants to support common features. The page table allocator for DARTsis less complex since it uses a two levels of translation table withoutsupport for huge pages.Signed-off-by: Janne Grunau Acked-by: Robin Murphy Acked-by: Sven Peter Acked-by: Hector Martin Link: https://lore.kernel.org/r/20220916094152.87137-3-j@jannau.net[ joro: Fix compile warning in __dart_alloc_pages()]Signed-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/Makefile

fc36479d - iommu: Add a page fault handler

Thu, 01 Apr 2021 15:47:15 +0000

iommu: Add a page fault handlerSome systems allow devices to handle I/O Page Faults in the core mm. Forexample systems implementing the PCIe PRI extension or Arm SMMU stallmodel. Infrastructure for reporting these recoverable page faults wasadded to the IOMMU core by commit 0c830e6b3282 ("iommu: Introduce devicefault report API"). Add a page fault handler for host SVA.IOMMU driver can now instantiate several fault workqueues and link themto IOPF-capable devices. Drivers can choose between a single globalworkqueue, one per IOMMU device, one per low-level fault queue, one perdomain, etc.When it receives a fault event, most commonly in an IRQ handler, theIOMMU driver reports the fault using iommu_report_device_fault(), whichcalls the registered handler. The page fault handler then calls the mmfault handler, and reports either success or failure withiommu_page_response(). After the handler succeeds, the hardware retriesthe access.The iopf_param pointer could be embedded into iommu_fault_param. Butputting iopf_param into the iommu_param structure allows us not to careabout ordering between calls to iopf_queue_add_device() andiommu_register_device_fault_handler().Tested-by: Lu Baolu Reviewed-by: Eric Auger Reviewed-by: Jacob Pan Reviewed-by: Jonathan Cameron Reviewed-by: Lu Baolu Signed-off-by: Jean-Philippe Brucker Link: https://lore.kernel.org/r/20210401154718.307519-7-jean-philippe@linaro.orgSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/Makefile

ab362fff - iommu/arm-smmu: Restore naming of driver parameter prefix

iommu/arm-smmu: Restore naming of driver parameter prefixExtending the Arm SMMU driver to allow for modular builds changedKBUILD_MODNAME to be "arm_smmu_mod" so that a single module could bebuilt from the multiple existing object files without the need to renameany source files.This inadvertently changed the name of the driver parameters, which maylead to runtime issues if bootloaders are relying on the old names forcorrectness (e.g. "arm-smmu.disable_bypass=0").Although MODULE_PARAM_PREFIX can be overridden to restore the old namingfor builtin parameters, only the new name is matched by modprobe and soloading the driver as a module would cause parameters specified on thekernel command line to be ignored. Instead, rename "arm_smmu_mod" to"arm_smmu". Whilst it's a bit of a bodge, this allows us to create asingle module without renaming any files and makes use of the fact thatunderscores and hyphens can be used interchangeably in parameter names.Cc: Robin Murphy Cc: Russell King Reported-by: Li Yang Fixes: cd221bd24ff5 ("iommu/arm-smmu: Allow building as a module")Signed-off-by: Will Deacon Reviewed-by: Robin Murphy Signed-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/Makefile
