2025-05-26drm: Add helpers for programming hardware gamma LUTsThomas Zimmermann1-0/+206
Provide helpers that program hardware gamma LUTs. Tha gamma ramp is either provided by the driver or generated by the helper. The DRM driver exports the GAMMA_LUT property with a fixed number of entries per color component, such as 256 on 8-bit-wide components. The entries describe the gamma ramp of each individual component. The new helper drm_crtc_load_gamma_888() loads such gamma ramp to hardware. The hardware uses each displayed pixel's individial components as indices into the hardware gamma table. For color modes with less than 8 bits per color component, the helpers drm_crtc_load_gamma_565_from() and drm_crtc_load_gamma_555_from_888() interpolate the provided gamma ramp to reduce it to the correct number of entries; 5/6/5 for RGB565-like formats and 5/5/5 for XRGB1555-like formats. If no gamma ramp has been provided, drivers can use the new helper drm_crtc_fill_gamma_888() to load a default gamma ramp with 256 entries per color component. For color modes with less bits, the new helpers drm_crtc_fill_gamma_565() and drm_crtc_fill_gamma_555() are available. The default gamma ramp uses a gamma factor of 1. For color modes with palette, drm_crtc_load_palette_8() load an 8-bit palette into the hardware. If no palette has been specified, drm_crtc_fill_palette_8() load a system-specific default palette. This is currently only a grey-scale palette with increasing luminance, but later patches can change this. For PCs, a VGA default palette could be used. v2: - drop comment on gamma factor of 2.2 (Michel, Pekka) - fix typos in commit description (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Acked-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20250520094203.30545-2-tzimmermann@suse.de

2025-05-23drm: convert many bridge drivers from devm_kzalloc() to ↵Luca Ceresoli49-198/+201
devm_drm_bridge_alloc() API devm_drm_bridge_alloc() is the new API to be used for allocating (and partially initializing) a private driver struct embedding a struct drm_bridge. For many drivers having a simple code flow in the probe function, this commit does a mass conversion automatically with the following semantic patch. The changes have been reviewed manually for correctness as well as to find any false positives. The patch has been applied with the explicit exclusion of bridge/panel.c, handled by a separate patch. After applying the semantic patch, manually fixed these issues: - 4 drivers need ERR_CAST() instead of PTR_ERR() as the function calling devm_drm_bridge_alloc() returns a pointer - re-added empty lines and comments that the script had removed but that should stay @@ type T; identifier C; identifier BR; expression DEV; expression FUNCS; @@ -T *C; +T *C; ...

Platforms that do not support SLPC are exempted from the GuC PC support. The GuC PC does not get initialized, and neither do its BOs get created. This causes a problem because the GuC PC debugfs file is still being created. Whenever the file is attempted to read, it causes a NULL pointer dereference on the supposed BO of the GuC PC. So, make the creation of SLPC debugfs files conditional to when SLPC features are supported.

Add a new dcdebugmask value that can be used to skip the detection LT Reviewed-by: Tom Chung <chiahsuan.chung@amd.com> Link: https://lore.kernel.org/amd-gfx/20250521063934.2111323-1-Wayne.Lin@amd.com/ Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
