-/* Interface history:

- * 1.x The DRM driver from the VIA/S3 code drop, basically a dummy
- * 2.0 The first real DRM
- * 2.1 Scissors registers managed by the DRM, 3D operations clipped by
- * 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
- * actually used
