2025-09-16drm/amd/display: Set up pixel encoding for YCBCR422Mario Limonciello1-0/+3
[Why] fill_stream_properties_from_drm_display_mode() will not configure pixel encoding to YCBCR422 when the DRM color format supports YCBCR422 but not YCBCR420 or YCBCR4444. Instead it will fallback to RGB. [How] Add support for YCBCR422 in pixel encoding mapping.

[Why&How] As reported on https://gitlab.freedesktop.org/drm/amd/-/issues/3936, SMU hang can occur if the interrupts are not enabled appropriately, causing a vblank timeout.

2025-09-15drm/amdgpu/gfx11: Add Cleaner Shader Support for GFX11.0.1/11.0.4 GPUsSrinivasan Shanmugam1-0/+15
Enable the cleaner shader for additional GFX11.0.1/11.0.4 series GPUs to ensure data isolation among GPU tasks. The cleaner shader is tasked with clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps avoid data leakage and guarantees the accuracy of computational results. This update extends cleaner shader support to GFX11.0.1/11.0.4 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.

This commit is necessary for DC to function well with chips that use the legacy power management code, ie. SI and KV. Communicate display information from DC to the legacy PM code. Currently DC uses pm_display_cfg to communicate power management requirements from the display code to the DPM code. However, the legacy (non-DC) code path used different fields and therefore could not take into account anything from DC. Change the legacy display code to fill the same pm_display_cfg struct as DC and use the same in the legacy DPM code. To ease review and reduce churn, this commit does not yet delete the now unneeded code, that is done in the next commit. v2: Rebase. Fix single_display in amdgpu_dpm_pick_power_state.

This commit adds the pixel_clock field to the display config struct so that power management (DPM) can use it. We currently don't have a proper bandwidth calculation on old GPUs with DCE 6-10 because dce_calcs only supports DCE 11+. So the power management (DPM) on these GPUs may need to make ad-hoc decisions for display based on the pixel clock. Also rename sym_clock to pixel_clock in dm_pp_single_disp_config to avoid confusion with other code where the sym_clock refers to the DisplayPort symbol clock.

Bookkeeping: - adev->rmmio_remap.bo : kernel-owned singleton BO The BO is allocated during TTM init when a remap bus address is available (adev->rmmio_remap.bus_addr) and PAGE_SIZE <= AMDGPU_GPU_PAGE_SIZE (4K), and freed during TTM fini. v2: - Check mmio_remap bus address (adev->rmmio_remap.bus_addr) instead of rmmio_base.

2025-09-15drm/xe/guc: Add test for G2G communicationsJohn Harrison8-0/+801
Add a test for sending messages from every GuC to every other GuC to test G2G communications. Note that, being a debug only feature, the test interface only exists in pre-production builds of the GuC firmware. v2: Fix 'default' case to actually use the driver's registration code as well as allocation. Add comments explaining the different test types. Fix (C) date and an assert. Review feedback from Daniele.

2025-09-15drm/xe: Allow freeing of a managed boJohn Harrison2-0/+6
If a bo is created via xe_managed_bo_create_pin_map() then it cannot be freed by the driver using xe_bo_unpin_map_no_vm(), or indeed any other existing function. The DRM layer will still have a pointer stashed away for later freeing, causing a invalid memory access on driver unload. So add a helper for releasing the DRM action as well. v2: Drop 'xe' parameter (review feedbak from Michal W) Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://lore.kernel.org/r/20250910210237.603576-4-John.C.Harrison@Intel.com

Some test features are not available in production builds of the GuC firmware. So add the build type field to the available information that tests can inspect to decide if they should skip or run.

2025-09-15drm/xe/guc: Update CSS header structuresJohn Harrison2-35/+53
Rework the CSS header structure according to recent updates to the GuC API spec. Also include more field definitions. v2: Also pass the new GuC specific structure to a GuC specific function instead of the higher level, generic structure (review feedback from Daniele). Also correct naming of CSS_TIME_* fields.
