/**

 * struct vmw_kms_dirty - closure structure for the vmw_kms_helper_dirty

 * function.

 *

 * @fifo_commit: Callback that is called once for each display unit after

 * all clip rects. This function must commit the fifo space reserved by the

 * helper. Set up by the caller.

 * @clip: Callback that is called for each cliprect on each display unit.

 * Set up by the caller.

 * @fifo_reserve_size: Fifo size that the helper should try to allocat for

 * each display unit. Set up by the caller.

 * @dev_priv: Pointer to the device private. Set up by the helper.

 * @unit: The current display unit. Set up by the helper before a call to @clip.

 * @cmd: The allocated fifo space. Set up by the helper before the first @clip

 * call.

 * @num_hits: Number of clip rect commands for this display unit.

 * Cleared by the helper before the first @clip call. Updated by the @clip

 * callback.

 * @fb_x: Clip rect left side in framebuffer coordinates.

 * @fb_y: Clip rect right side in framebuffer coordinates.

 * @unit_x1: Clip rect left side in crtc coordinates.

 * @unit_y1: Clip rect top side in crtc coordinates.

 * @unit_x2: Clip rect right side in crtc coordinates.

 * @unit_y2: Clip rect bottom side in crtc coordinates.

 *

 * The clip rect coordinates are updated by the helper for each @clip call.

 * Note that this may be derived from if more info needs to be passed between

 * helper caller and helper callbacks.
