57 * - GET_UNIQUE ioctl, implemented by drm_getunique is wrapped up in libdrm
59 * - The libdrm drmSetBusid function is backed by the SET_UNIQUE ioctl. All
62 * exclusively use by the SET_VERSION ioctl, because only drm 1.0 (which is
63 * nerved) allowed userspace to set the busid through the above ioctl.
85 * name returned by that ioctl. Note that SET_VERSION is not called, which
188 * Hollowed-out getclient ioctl to keep some dead old drm tests/tools
372 * Setversion ioctl.
428 * drm_noop - DRM no-op ioctl implementation
429 * @dev: DRM device for the ioctl
430 * @data: data pointer for the ioctl
431 * @file_priv: DRM file for the ioctl call
435 * checks the result of the ioctl, but doesn't care about the action.
448 * drm_invalid_op - DRM invalid ioctl implementation
449 * @dev: DRM device for the ioctl
450 * @data: data pointer for the ioctl
451 * @file_priv: DRM file for the ioctl call
454 * functionality where we really don't want to allow userspace to call the ioctl
