2024-11-08drm/amdgpu/gfx11: Enable cleaner shader for GFX11.0.0/11.0.2 GPUsSrinivasan Shanmugam
Enable the cleaner shader for GFX11.0.0/11.0.2 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 GFX11.0.0/11.0.2 GPUs, previously available for GFX11.0.3. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

2024-11-05drm/amdgpu/gfx11: Add cleaner shader for GFX11.0.3Srinivasan Shanmugam
This commit adds the cleaner shader microcode for GFX11.0.3 GPUs. The cleaner shader is a piece of GPU code that is used to clear or initialize certain GPU resources, such as Local Data Share (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs). Clearing these resources is important for ensuring data isolation between different workloads running on the GPU. Without the cleaner shader, residual data from a previous workload could potentially be accessed by a subsequent workload, leading to data leaks and incorrect computation results. The cleaner shader microcode is represented as an array of 32-bit words (`gfx_11_0_3_cleaner_shader_hex`). This array is the binary representation of the cleaner shader code, which is written in a low-level GPU instruction set. When the cleaner shader feature is enabled, the AMDGPU driver loads this array into a specific location in the GPU memory. The GPU then reads this memory location to fetch and execute the cleaner shader instructions. The cleaner shader is executed automatically by the GPU at the end of each workload, before the next workload starts. This ensures that all GPU resources are in a clean state before the start of each workload. This addition is part of the cleaner shader feature implementation. The cleaner shader feature helps resource utilization by cleaning up GPU resources after they are used. It also enhances security and reliability by preventing data leaks between workloads.

2024-11-05drm/amd/pm: add zero RPM stop temperature OD setting support for SMU13Wolfgang Müller
Together with the feature to enable or disable zero RPM in the last commit, it also makes sense to expose the OD setting determining under which temperature the fan should stop if zero RPM is enabled.

Whilst we have support for setting fan curves there is no support for disabling the zero RPM feature. Since the relevant bits are already present in the OverDriveTable, hook them up to a sysctl setting so users can influence this behaviour.

2024-11-04drm/amdgpu: prevent NULL pointer dereference if ATIF is not supportedAntonio Quartulli
acpi_evaluate_object() may return AE_NOT_FOUND (failure), which would result in dereferencing buffer.pointer (obj) while being NULL. Although this case may be unrealistic for the current code, it is still better to protect against possible bugs. Bail out also when status is AE_NOT_FOUND.
