2025-04-07drm/xe: Allow scratch page under fault mode for certain platformOak Zeng
Normally scratch page is not allowed when a vm is operate under page fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason is fault mode relies on recoverable page to work, while scratch page can mute recoverable page fault. On xe2 and xe3, out of bound prefetch can cause page fault and further system hang because xekmd can't resolve such page fault. SYCL and OCL language runtime requires out of bound prefetch to be silently dropped without causing any functional problem, thus the existing behavior doesn't meet language runtime requirement. At the same time, HW prefetching can cause page fault interrupt. Due to page fault interrupt overhead (i.e., need Guc and KMD involved to fix the page fault), HW prefetching can be slowed by many orders of magnitude. Fix those problems by allowing scratch page under fault mode for xe2 and xe3. With scratch page in place, HW prefetching could always hit scratch page instead of causing interrupt. A side effect is, scratch page could hide application program error. Application out of bound accesses are hided by scratch page mapping, instead of get reported to user. v2: Refine commit message (Thomas) v3: Move the scratch page flag check to after scratch page wa (Thomas) v4: drop NEEDS_SCRATCH macro (matt) Add a comment to DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE Signed-off-by: Oak Zeng <oak.zeng@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Link: https://lore.kernel.org/r/20250403165328.2438690-4-oak.zeng@intel.com Signed-off-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com>

2025-03-14drm: add modifiers for Apple GPU layoutsAlyssa Rosenzweig
Apple GPUs support non-linear "GPU-tiled" image layouts. Add modifiers for these layouts. Mesa requires these modifiers to share non-linear buffers across processes, but no other userspace or kernel support is required/expected. These layouts are notably not used for interchange across hardware blocks (e.g. with the display controller). There are other layouts for that but we don't support them either in userspace or kernelspace yet (even downstream), so we don't add modifiers here.

2025-03-06drm/xe/uapi: Add DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRRORMatthew Brost
Add the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag, which is used to create unpopulated virtual memory areas (VMAs) without memory backing or GPU page tables. These VMAs are referred to as CPU address mirror VMAs. The idea is that upon a page fault or prefetch, the memory backing and GPU page tables will be populated. CPU address mirror VMAs only update GPUVM state; they do not have an internal page table (PT) state, nor do they have GPU mappings. It is expected that CPU address mirror VMAs will be mixed with buffer object (BO) VMAs within a single VM. In other words, system allocations and runtime allocations can be mixed within a single user-mode driver (UMD) program. Expected usage: - Bind the entire virtual address (VA) space upon program load using the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag. - If a buffer object (BO) requires GPU mapping (runtime allocation), allocate a CPU address using mmap(PROT_NONE), bind the BO to the mmapped address using existing bind IOCTLs. If a CPU map of the BO is needed, mmap it again to the same CPU address using mmap(MAP_FIXED) - If a BO no longer requires GPU mapping, munmap it from the CPU address space and them bind the mapping address with the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag. - Any malloc'd or mmapped CPU address accessed by the GPU will be faulted in via the SVM implementation (system allocation). - Upon freeing any mmapped or malloc'd data, the SVM implementation will remove GPU mappings. Only supporting 1 to 1 mapping between user address space and GPU address space at the moment as that is the expected use case. uAPI defines interface for non 1 to 1 but enforces 1 to 1, this restriction can be lifted if use cases arrise for non 1 to 1 mappings. This patch essentially short-circuits the code in the existing VM bind paths to avoid populating page tables when the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag is set. v3: - Call vm_bind_ioctl_ops_fini on -ENODATA - Don't allow DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR on non-faulting VMs - s/DRM_XE_VM_BIND_FLAG_SYSTEM_ALLOCATOR/DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR (Thomas) - Rework commit message for expected usage (Thomas) - Describe state of code after patch in commit message (Thomas) v4: - Fix alignment (Checkpatch) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-9-matthew.brost@intel.com

2025-02-26drm/xe/uapi: Introduce API for EU stall samplingHarish Chegondi
A new hardware feature first introduced in PVC gives capability to periodically sample EU stall state and record counts for different stall reasons, on a per IP basis, aggregate across all EUs in a subslice and record the samples in a buffer in each subslice. Eventually, the aggregated data is written out to a buffer in the memory. This feature is also supported in XE2 and later architecture GPUs. Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the driver from the user space to do initial setup and obtain a file descriptor for the EU stall data stream. Input parameter to the IOCTL is a struct drm_xe_observation_param in which observation_type should be set to DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of drm_xe_ext_set_property structures in which each structure has a pair of property and value. The EU stall sampling input properties are defined in drm_xe_eu_stall_property_id enum. With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space can enable and disable EU stall sampling with the IOCTLs: DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE. User space can also call poll() to check for availability of data in the buffer. The data can be read with read(). Finally, the file descriptor can be closed with close(). v11: Changed a couple of variables in struct eu_stall_open_properties from unsigned int to int. v10: Use extension number while parsing chain of extensions. Remove function description for static functions. Move code around as per review feedback. v9: Changed some u32 to unsigned int. Moved some code around as per review feedback from v8. v8: Used div_u64 instead of / to fix 32-bit build issue. Changed copyright year in xe_eu_stall.c/h to 2025. v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with OA. Renamed the corresponding internal variables. Fixed some commit messages based on review feedback. v6: Change the input sampling rate to GPU cycles instead of GPU cycles multiplier.

2025-02-03drm/xe/pxp/uapi: Add API to mark a BO as using PXPDaniele Ceraolo Spurio
The driver needs to know if a BO is encrypted with PXP to enable the display decryption at flip time. Furthermore, we want to keep track of the status of the encryption and reject any operation that involves a BO that is encrypted using an old key. There are two points in time where such checks can kick in: 1 - at VM bind time, all operations except for unmapping will be rejected if the key used to encrypt the BO is no longer valid. This check is opt-in via a new VM_BIND flag, to avoid a scenario where a malicious app purposely shares an invalid BO with a non-PXP aware app (such as a compositor). If the VM_BIND was failed, the compositor would be unable to display anything at all. Allowing the bind to go through means that output still works, it just displays garbage data within the bounds of the illegal BO. 2 - at job submission time, if the queue is marked as using PXP, all objects bound to the VM will be checked and the submission will be rejected if any of them was encrypted with a key that is no longer valid. Note that there is no risk of leaking the encrypted data if a user does not opt-in to those checks; the only consequence is that the user will not realize that the encryption key is changed and that the data is no longer valid. v2: Better commnnts and descriptions (John), rebase v3: Properly return the result of key_assign up the stack, do not use xe_bo in display headers (Jani) v4: improve key_instance variable documentation (John) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250129174140.948829-11-daniele.ceraolospurio@intel.com

2025-01-16drm/xe/mmap: Add mmap support for PCI memory barrierTejas Upadhyay
In order to avoid having userspace to use MI_MEM_FENCE, we are adding a mechanism for userspace to generate a PCI memory barrier with low overhead (avoiding IOCTL call as well as writing to VRAM will adds some overhead). This is implemented by memory-mapping a page as uncached that is backed by MMIO on the dGPU and thus allowing userspace to do memory write to the page without invoking an IOCTL. We are selecting the MMIO so that it is not accessible from the PCI bus so that the MMIO writes themselves are ignored, but the PCI memory barrier will still take action as the MMIO filtering will happen after the memory barrier effect. When we detect special defined offset in mmap(), We are mapping 4K page which contains the last of page of doorbell MMIO range to userspace for same purpose. For user to query special offset we are adding special flag in mmap_offset ioctl which needs to be passed as follows, struct drm_xe_gem_mmap_offset mmo = { .handle = 0, /* this must be 0 */ .flags = DRM_XE_MMAP_OFFSET_FLAG_PCI_BARRIER, }; igt_ioctl(fd, DRM_IOCTL_XE_GEM_MMAP_OFFSET, &mmo); map = mmap(NULL, size, PROT_WRITE, MAP_SHARED, fd, mmo); IGT : https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commit/b2dbc6f22815128c0dd5c737504f42e1f1a6ad62 UMD : https://github.com/intel/compute-runtime/pull/772 V7: - Dgpu filter added V6(MAuld) - Move physical mmap to fault handler - Modify kernel-doc and attach UMD PR when ready V5(MAuld) - Return invalid early in case of non 4K PAGE_SIZE - Format kernel-doc and add note for 4K PAGE_SIZE HW limit V4(MAuld) - Add kernel-doc for uapi change - Restrict page size to 4K V3(MAuld) - Remove offset defination from UAPI to be able to change later - Edit commit message for special flag addition V2(MAuld) - Add fault handler with dummy page to handle unplug device - Add Build check for special offset to be below normal start page - Test d3hot, mapping seems to be valid in d3hot as well - Add more info to commit message Cc: Matthew Auld <matthew.auld@intel.com> Acked-by: Michal Mrozek <michal.mrozek@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Tejas Upadhyay <tejas.upadhyay@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250113114201.3178806-1-tejas.upadhyay@intel.com
