# drm\_framebuffer\_cleanup(9)

remove a framebuffer object

## 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.
