Originally, a write to SYNC would implicitly + * trigger a read from BUSY. This causes us to synchronously + * process the FIFO. + * + * This behaviour has since been changed so that writing SYNC + * will *not* implicitly cause a read from BUSY. Instead, it + * makes a channel call which asynchronously wakes up the MKS + * thread. + * + * New guests can use this new behaviour to implement (2) + * efficiently.

Drivers should set + * SVGA_FIFO_BUSY to TRUE after writing to SYNC.
