Name
drm_helper_crtc_mode_set_base —
mode_set_base implementation for atomic plane helpers
Synopsis
int drm_helper_crtc_mode_set_base ( | struct drm_crtc * crtc, |
| | int x, |
| | int y, |
| | struct drm_framebuffer * old_fb); |
Arguments
crtc
DRM CRTC
x
x offset of the CRTC scanout area on the underlying framebuffer
y
y offset of the CRTC scanout area on the underlying framebuffer
old_fb
previous framebuffer
Description
This function implements a callback useable as the ->mode_set_base used
required by the crtc helpers. The driver must provide the atomic plane helper
functions for the primary plane.
This is a transitional helper useful for converting drivers to the atomic
interfaces.
