Thomas Zimmermann 80f7c3f776 drm/vram: Add helpers to validate a display mode's memory requirements ... Devices with low amount of dedicated video memory may not be able to use all possible display modes, as the framebuffers may not fit into VRAM. The new helper function drm_vram_helper_mode_valid() implements a simple test to sort out all display modes that can not be used in any case. Drivers should call this function from struct drm_mode_config_funcs.mode_valid. The functionality was originally implemented by the ast driver, which is being converted as well. v2: * WARN_ON if VRAM memory manager has not been initialized * documentation fixes * unexported drm_vram_helper_mode_valid_internal() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200203155258.9346-2-tzimmermann@suse.de		2020-02-06 10:32:54 +01:00
