video: Make global edid_info depend on CONFIG_FIRMWARE_EDID

2025-06-16T09:00:29+00:00

Protect global edid_info behind CONFIG_FIRMWARE_EDID and remove
the config tests for CONFIG_X86. Makes edid_info available iff
its option has been enabled.

fbdev/sisfb: Unexport symbols

2025-06-16T07:08:06+00:00

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.
Also remove the related, but unused, define SISFB_HAVE_MALLOC_NEW.

v2:
- remove unused functions (Helge)

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)
