2025-01-10drm/amd/display: Extend secure display to support DisplayCRC modeWayne Lin
[Why] For the legacy secure display, it involves PSP + DMUB to confgiure and retrieve the CRC/ROI result. Have requirement to support mode which all handled by driver only. [How] Add another "DisplayCRC" mode, which doesn't involve PSP + DMUB.

2025-01-10drm/amd/display: Add support to configure CRC window on specific CRC instanceWayne Lin
[Why] Have the need to specify the CRC window on specific CRC engine. dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always resets CRC engine at first. [How] Add index parameter to dc_stream_configure_crc() for selecting the desired crc engine. Additionally, add another parameter to specify whether to skip the default reset of crc engine.

2025-01-10drm/amd/display: Reduce accessing remote DPCD overheadWayne Lin
[Why] Observed frame rate get dropped by tool like glxgear. Even though the output to monitor is 60Hz, the rendered frame rate drops to 30Hz lower. It's due to code path in some cases will trigger dm_dp_mst_is_port_support_mode() to read out remote Link status to assess the available bandwidth for dsc maniplation. Overhead of keep reading remote DPCD is considerable. [How] Store the remote link BW in mst_local_bw and use end-to-end full_pbn as an indicator to decide whether update the remote link bw or not. Whenever we need the info to assess the BW, visit the stored one first.

2025-01-10drm/amd/display: Validate mdoe under MST LCT=1 case as wellWayne Lin
[Why & How] Currently in dm_dp_mst_is_port_support_mode(), when valdidating mode under dsc decoding at the last DP link config, we only validate the case when there is an UFP. However, if the MSTB LCT=1, there is no UFP. Under this case, use root_link_bw_in_kbps as the available bw to compare.

2025-01-09drm/amdgpu: Fix shift type in amdgpu_debugfs_sdma_sched_mask_set()Dan Carpenter
The "mask" and "val" variables are type u64. The problem is that the BIT() macros are type unsigned long which is just 32 bits on 32bit systems. It's unlikely that people will be using this driver on 32bit kernels and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16) bits. So this bug does not affect anything in real life. Still, for correctness sake, u64 bit masks should use BIT_ULL().

In the case of the second warning, there was a rather dramatic increase in stack usage compared to the parent: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ This is an unfortunate interaction between an issue with stack slot reuse in LLVM that gets exacerbated by sanitization (which gets enabled with all{mod,yes}config) and function calls using a much higher number of parameters than is typical in the kernel, necessitating passing most of these values on the stack. While it is possible that there should be source code changes to address these warnings, this code is difficult to modify for various reasons, as has been noted in other changes that have occurred for similar reasons, such as commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2"). Increase the frame larger than limit when compile testing with clang and the sanitizers enabled to avoid this breakage in all{mod,yes}config, as they are commonly used and valuable testing targets. While it is not the best to hide this issue, it is not really relevant when compile testing, as the sanitizers are commonly stressful on optimizations and they are only truly useful at runtime, which COMPILE_TEST states will not occur with the current build.

2025-01-06drm/amdgpu/gfx10: Add cleaner shader for GFX10.3.0Srinivasan Shanmugam
This commit adds the cleaner shader microcode for GFX10.3.0 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_10_3_0_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.

2025-01-06drm/amdkfd: wq_release signals dma_fence only when availableZhu Lingshan
kfd_process_wq_release() signals eviction fence by dma_fence_signal() which wanrs if dma_fence is NULL. kfd_process->ef is initialized by kfd_process_device_init_vm() through ioctl. That means the fence is NULL for a new created kfd_process, and close a kfd_process right after open it will trigger the warning. This commit conditionally signals the eviction fence in kfd_process_wq_release() only when it is available.
