1591 * - if si_need_dma_space has been called for the buffer
1592 *
1593 * - when emitting state packets and draw packets (because preceding packets
1594 * can't be re-emitted at that point)
1595 *
1596 * - if shader resource "enabled_mask" is not up-to-date or there is
1597 * a different constraint disallowing a context flush
