- * Number of bytes to reserve for commands necessary to complete a batch.
- *
- * This includes:
- * - MI_BATCHBUFFER_END (4 bytes)
- * - Optional MI_NOOP for ensuring the batch length is qword aligned (4 bytes)
- * - Any state emitted by vtbl->finish_batch():
- * - Gen4-5 record ending occlusion query values (4 * 4 = 16 bytes)
- * - Disabling OA counters on Gen6+ (3 DWords = 12 bytes)
- * - Ending MI_REPORT_PERF_COUNT on Gen5+, plus associated PIPE_CONTROLs:
- * - Two sets of PIPE_CONTROLs, which become 3 PIPE_CONTROLs each on SNB,
- * which are 5 DWords each ==> 2 * 3 * 5 * 4 = 120 bytes
- * - 3 DWords for MI_REPORT_PERF_COUNT itself on Gen6+. ==> 12 bytes.
- * On Ironlake, it's 6 DWords, but we have some slack due to the lack of
- * Sandybridge PIPE_CONTROL madness.
- * - CC_STATE workaround on HSW (12 * 4 = 48 bytes)
- * - 5 dwords for initial mi_flush
- * - 2 dwords for CC state setup
- * - 5 dwords for the required pipe control at the end
