 *       cliprects of the cmdbuf ioctl
 * 2.2   Implemented SAVAGE_CMD_DMA_IDX and SAVAGE_CMD_VB_IDX
 * 2.3   Event counters used by BCI_EVENT_EMIT/WAIT ioctls are now 32 bits
 *       wide and thus very long lived (unlikely to ever wrap). The size
 *       in the struct was 32 bits before, but only 16 bits were used
 * 2.4   Implemented command DMA. Now drm_savage_init_t.cmd_dma_offset is
