2025-06-30drm/amdgpu: remove job parameter from amdgpu_fence_emit()Alex Deucher
What we actually care about is the amdgpu_fence object so pass that in explicitly to avoid possible mistakes in the future. The job_run_counter handling can be safely removed at this point as we no longer support job resubmission.

2025-06-30drm/amdkfd: add hqd_sdma_get_doorbell callbacks for gfx7/8Alex Deucher

2025-06-24drm/amd: Adjust output for discovery error handlingMario Limonciello
commit 017fbb6690c2 ("drm/amdgpu/discovery: check ip_discovery fw file available") added support for reading an amdgpu IP discovery bin file for some specific products. If it's not found then it will fallback to hardcoded values. However if it's not found there is also a lot of noise about missing files and errors. Adjust the error handling to decrease most messages to DEBUG and to show users less about missing files.

2025-06-24drm/amdgpu/gfx9: Add Cleaner Shader Support for GFX9.x GPUsSrinivasan Shanmugam
Enable the cleaner shader for other GFX9.x series of GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX9.x GPUs, previously available for GFX9.4.2. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

2025-06-24drm/amdgpu: fix slab-use-after-free in amdgpu_userq_mgr_fini+0x70cVitaly Prosyak
The issue was reproduced on NV10 using IGT pci_unplug test. It is expected that `amdgpu_driver_postclose_kms()` is called prior to `amdgpu_drm_release()`. However, the bug is that `amdgpu_fpriv` was freed in `amdgpu_driver_postclose_kms()`, and then later accessed in `amdgpu_drm_release()` via a call to `amdgpu_userq_mgr_fini()`. As a result, KASAN detected a use-after-free condition, as shown in the log below. The proposed fix is to move the calls to `amdgpu_eviction_fence_destroy()` and `amdgpu_userq_mgr_fini()` into `amdgpu_driver_postclose_kms()`, so they are invoked before `amdgpu_fpriv` is freed. This also ensures symmetry with the initialization path in `amdgpu_driver_open_kms()`, where the following components are initialized: - `amdgpu_userq_mgr_init()` - `amdgpu_eviction_fence_init()` - `amdgpu_ctx_mgr_init()` Correspondingly, in `amdgpu_driver_postclose_kms()` we should clean up using: - `amdgpu_userq_mgr_fini()` - `amdgpu_eviction_fence_destroy()` - `amdgpu_ctx_mgr_fini()` This change eliminates the use-after-free and improves consistency in resource management between open and close paths.

2025-06-24drm/amd: Adjust output for discovery error handlingMario Limonciello
commit 017fbb6690c2 ("drm/amdgpu/discovery: check ip_discovery fw file available") added support for reading an amdgpu IP discovery bin file for some specific products. If it's not found then it will fallback to hardcoded values. However if it's not found there is also a lot of noise about missing files and errors. Adjust the error handling to decrease most messages to DEBUG and to show users less about missing files.

2025-06-24drm/amdgpu/gfx9: Add Cleaner Shader Support for GFX9.x GPUsSrinivasan Shanmugam
Enable the cleaner shader for other GFX9.x series of GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX9.x GPUs, previously available for GFX9.4.2. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

This commit makes the following improvements to SDMA engine reset handling: 1. Clarifies in the function documentation that instance_id refers to a logical ID 2. Adds conversion from logical to physical instance ID before performing reset using GET_INST(SDMA0, instance_id) macro 3. Improves error messaging to indicate when a logical instance reset fails 4.
