2025-04-22drm/amdgpu: Add queue id support to the user queue wait IOCTLArunpravin Paneer Selvam
Add queue id support to the user queue wait IOCTL drm_amdgpu_userq_wait structure. This is required to retrieve the wait user queue and maintain the fence driver references in it so that the user queue in the same context releases their reference to the fence drivers at some point before queue destruction. Otherwise, we would gather those references until we don't have any more space left and crash. v2: Modify the UAPI comment as per the mesa and libdrm UAPI comment.

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

2025-03-05drm/xe/uapi: Use hint for guc to set GT frequencyTejas Upadhyay
Allow user to provide a low latency hint. When set, KMD sends a hint to GuC which results in special handling for that process. SLPC will ramp the GT frequency aggressively every time it switches to this process.

2025-02-26drm/xe/uapi: Add a device query to get EU stall sampling informationHarish Chegondi
User space can get the EU stall data record size, EU stall capabilities, EU stall sampling rates, and per XeCore buffer size with query IOCTL DRM_IOCTL_XE_DEVICE_QUERY with .query set to DRM_XE_DEVICE_QUERY_EU_STALL. A struct drm_xe_query_eu_stall will be returned to the user space along with an array of supported sampling rates sorted in the fastest sampling rate first order. sampling_rates in struct drm_xe_query_eu_stall will point to the array of sampling rates. Any capabilities in EU stall sampling as of this patch are considered as base capabilities. New capability bits will be added for any new functionality added later. v12: Rename has_eu_stall_sampling_support() to xe_eu_stall_supported_on_platform() and move it to header file. v11: Check if EU stall sampling is supported on the platform. v10: Change comments and variable names as per feedback v9: Move reserved fields above num_sampling_rates in struct drm_xe_query_eu_stall. v7: Change sampling_rates from a pointer to flexible array. v6: Include EU stall sampling rates information and per XeCore buffer size in the query information.

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.

2025-02-11thermal/netlink: Prevent userspace segmentation fault by adjusting UAPI headerZhang Rui
The intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITY attribute to receive HFI events from kernel space, encounters a segmentation fault after commit 1773572863c4 ("thermal: netlink: Add the commands and the events for the thresholds"). The issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw value was changed while intel_lpmd still uses the old value. Although intel_lpmd can be updated to check the THERMAL_GENL_VERSION and use the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commit itself is questionable. The commit introduced a new element in the middle of enum thermal_genl_attr, which affects many existing attributes and introduces potential risks and unnecessary maintenance burdens for userspace thermal netlink event users. Solve the issue by moving the newly introduced THERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of the enum thermal_genl_attr. This ensures that all existing thermal generic netlink attributes remain unaffected.

2025-02-06net: ethtool: tsconfig: Fix netlink type of hwtstamp flagsKory Maincent
Fix the netlink type for hardware timestamp flags, which are represented as a bitset of flags. Although only one flag is supported currently, the correct netlink bitset type should be used instead of u32 to keep consistency with other fields. Address this by adding a new named string set description for the hwtstamp flag structure. The code has been introduced in the current release so the uAPI change is still okay.

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
