NAME¶
drm_framebuffer_cleanup - remove a framebuffer objectSYNOPSIS¶
void
drm_framebuffer_cleanup(struct drm_framebuffer * fb);
ARGUMENTS¶
fbframebuffer to remove
DESCRIPTION¶
Cleanup framebuffer. This function is intended to be used from the drivers ->destroy callback. It can also be used to clean up driver private framebuffers embedded into a larger structure. Note that this function does not remove the fb from active usuage - if it is still used anywhere, hilarity can ensue since userspace could call getfb on the id and get back -EINVAL. Obviously no concern at driver unload time. Also, the framebuffer will not be removed from the lookup idr - for user-created framebuffers this will happen in in the rmfb ioctl. For driver-private objects (e.g. for fbdev) drivers need to explicitly call drm_framebuffer_unregister_private.AUTHORS¶
