2025-06-24drm/amd/pm: Add support to set min ISP clocksPratap Nirujogi
Add support to set ISP clocks for SMU v14.0.0. ISP driver uses amdgpu_dpm_set_soft_freq_range() API to set clocks via SMU interface than communicating with PMFW directly. amdgpu_dpm_set_soft_freq_range() is updated to take in any pp_clock_type than limiting to support only PP_SCLK to allow ISP and other driver modules to set the min/max clocks. Any clock specific restrictions are expected to be taken care in SOC specific SMU implementations instead of generic amdgpu_dpm and amdgpu_smu interfaces.

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.

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.

2025-06-24drm/amd/display: Include EQU Prefetch Bandwidth For Bandwidth CalculationsAustin Zheng
[Why] Pixel data bandwidth required in mode programming (MP) ends up being higher than what was calculated in mode support (MS) even though the prefetch bandwidths calculated in MP are lower than the MS ones. MP used a different equ prefetch schedule than MS which lead a slight difference in parameters. This resulted in the pixel data bandwidth in MP to be higher than MS. [How] Rename the RequiredPrefetchBWOTO term so it can be applied generically. Update the value with the EQU bandwidth if the EQU schedule is used. Get the max prefetch bandwidth that MS calculated and use it as part of the calculations for required bandwidth.

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.
