DRM_FRAMEBUFFER_CLEA(9) DRM Core DRM_FRAMEBUFFER_CLEA(9)

NAME

drm_framebuffer_cleanup - remove a framebuffer object

SYNOPSIS

void drm_framebuffer_cleanup(struct drm_framebuffer * fb);

ARGUMENTS

fb
framebuffer 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.
