| | uint32_t flags); |
Arguments
crtc
DRM crtc
fb
DRM framebuffer

flags
flip flags for non-vblank sync'ed updates
Description
Provides a default page flip implementation using the atomic driver interface.
Note that for now so called async page flips (i.e. updates which are not
synchronized to vblank) are not supported, since the atomic interfaces have
no provisions for this yet.
Returns
Returns 0 on success, negative errno numbers on failure.
