[PATCH 2/4] drm/pixel: Link format helpers into drm_pixel_helper.ko
Thomas Zimmermann
tzimmermann at suse.de
Mon Oct 19 08:32:43 PDT 2026
Move drm_format_helper.o from drm_kms_helper.ko to drm_pixel_helper.ko.
Select DRM_PIXEL_HELPER from the drivers that use the format helpers.
While at it, include <drm/drm_format_helper.h> in a few places where it
is missing.
Format helpers copy pixel data from a DRM framebuffer to a hardware
scanout buffer or some other destination. They can transform the color
format as part of the copying operation. A number of drivers require
this functionality as part of their display update.
The format helpers are currently part of drm_kms_helper.ko, which is
for mode-setting helpers (i.e, helpers that modify the display pipeline).
