drm/vesadrm: Support DRM_FORMAT_C8

2025-08-26T07:54:20+00:00

Add support for DRM_FORMAT_C8 to vesadrm. The new pixel-format description PIXEL_FORMAT_C8 describes the layout. Vesadrm's helpers vesadrm_fill_palette_lut() and vesadrm_load_palette_lut() set the hardware palette according to the CRTC's output format. The driver emulates XRGB8888 by converting the source buffer to RGB332 and using the resulting 256 colors as index into the hardware palette. The hardware palette converts back to RGB during scanout. This has no overhead compared to other format conversion, but allows common userspace, such as Wayland compositors, to operate on the display.

Fix the compile-time warning drivers/video/fbdev/sis/sis_main.c: warning: EXPORT_SYMBOL() is used, but #include is missing The affected symbols are not used outside of their module. Some of the symbols are not used anywhere, so remove the functions entirely.

drm/sysfb: Add efidrm for EFI displays

2025-04-07T09:02:07+00:00

Add support for screen_info setups with VIDEO_TYPE_EFI. Provide the minimum functionality of reading modes, updating and clearing the display. There is existing support for these displays provided by simpledrm with CONFIG_SYSFB_SIMPLEFB=y. Using efidrm over simpledrm will allows for the mapping of video memory with correct caching. Simpledrm always assumes WC caching, while fully cached memory is possible with efidrm. Efidrm will also allow for the use of additional functionality provided by EFI, such as EDID information. In addition to efidrm, add struct pixel_format plus initializer macros. The type and macros describe pixel formats in a generic way on order to find the DRM format from the screen_info settings. Similar existing code in SIMPLEFB_FORMATS and fbdev is not really what is needed in efidrm, but SIMPLEFB_FORMATS can later be converted to struct pixel_format. v4: - depend on CONFIG_EFI - disallow module for now as efi_mem_desc_lookup() is not exported v3: - depend on !SYSFB_SIMPLEFB (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://lore.kernel.org/r/20250401094056.32904-15-tzimmermann@suse.de
