[PATCH v11 0/8] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks. [1] https://lore.kernel.org/linux-iommu/20231026044216.64964-1-yi.l.liu@intel.c… - merged [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1 Change log: v11: - Drop hw_error field in vtd cache invalidation uapi. devTLB invalidation error is a serious security emergency requiring the host kernel to handle. No need to expose it to userspace (especially given existing VMs doesn't issue devTLB invalidation at all). - The vtd qi_submit_sync() and related callers are reverted back to the original state due to above drop. - Align with the vtd path, drop the hw_error reporting in mock driver and selftest as well since selftest is a demo of the real driver. - Drop iommu_respond_struct_to_user_array() since no more driver want to respond single entry in the user_array. - Two typos from Wubinbin v10: https://lore.kernel.org/all/20240102143834.146165-1-yi.l.liu@intel.com/ - Minor tweak to patch 07 (Kevin) - Rebase on top of 6.7-rc8 v9: https://lore.kernel.org/linux-iommu/20231228150629.13149-1-yi.l.liu@intel.c… - Add a test case which sets both IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in flags, and expect to succeed and see an 'error'. (Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6. Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy(). Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (2): iommu: Add cache_invalidate_user op iommu/vt-d: Add iotlb flush for nested domain Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (2): iommufd: Add IOMMU_HWPT_INVALIDATE iommufd: Add data structure for Intel VT-d stage-1 cache invalidation drivers/iommu/intel/nested.c | 88 ++++++++++ drivers/iommu/iommufd/hw_pagetable.c | 41 +++++ drivers/iommu/iommufd/iommufd_private.h | 10 ++ drivers/iommu/iommufd/iommufd_test.h | 23 +++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 76 +++++++++ include/linux/iommu.h | 79 +++++++++ include/uapi/linux/iommufd.h | 79 +++++++++ tools/testing/selftests/iommu/iommufd.c | 152 ++++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 57 +++++++ 10 files changed, 608 insertions(+) -- 2.34.1

[PATCH AUTOSEL 6.6 08/14] selftests/nolibc: use EFI -bios for LoongArch qemu

by Sasha Levin

From: Thomas Weißschuh <linux(a)weissschuh.net> [ Upstream commit bdeeeaba83682225a7bf5f100fe8652a59590d33 ] qemu for LoongArch does not work properly with direct kernel boot. The kernel will panic during initialization and hang without any output. When booting in EFI mode everything work correctly. While users most likely don't have the LoongArch EFI binary installed at least an explicit error about 'file not found' is better than a hanging test without output that can never succeed.
