The MKS will - * eventually set SVGA_FIFO_BUSY on its own, but this approach - * lets the driver avoid sending multiple asynchronous wakeup - * messages to the MKS thread. + * The SYNC register can be used by the guest driver to signal to the + * device that the guest driver is waiting for previously submitted + * commands to complete. + * + * When the guest driver writes to the SYNC register, the device sets + * the BUSY register to TRUE, and starts processing the submitted commands + * (if it was not already doing so). When all previously submitted + * commands are finished and the device is idle again, it sets the BUSY + * register back to FALSE. (If the guest driver submits new commands + * after writing the SYNC register, the new commands are not guaranteed + * to have been procesesd.) + * + * When guest drivers are submitting commands using the FIFO, the device + * periodically polls to check for new FIFO commands when idle, which may + * introduce a delay in command processing. If the guest-driver wants + * the commands to be processed quickly (which it typically does), it + * should write SYNC after each batch of commands is committed to the + * FIFO to immediately wake up the device. For even better performance, + * the guest can use the SVGA_FIFO_BUSY register to avoid these extra + * SYNC writes if the device is already active, using the technique known + * as "Ringing the Doorbell" (described below). (Note that command + * buffer submission implicitly wakes up the device, and so doesn't + * suffer from this problem.) + * + * The SYNC register can also be used in combination with BUSY to + * synchronously ensure that all SVGA commands are processed (with both + * the FIFO and command-buffers). To do this, the guest driver should + * write to SYNC, and then loop reading BUSY until BUSY returns FALSE. + * This technique is known as a "Legacy Sync". * * SVGA_REG_BUSY -- * * This register is set to TRUE when SVGA_REG_SYNC is written, - * and it reads as FALSE when the FIFO has been completely - * drained. - * - * Every read from this register causes us to synchronously - * process FIFO commands. There is no guarantee as to how many - * commands each read will process. + * and is set back to FALSE when the device has finished processing + * all commands and is idle again. * - * CPU time spent processing FIFO commands will be billed to - * the guest. + * Every read from the BUSY reigster will block for an undefined + * amount of time (normally until the device finishes some interesting + * work unit), or the device is idle. * - * New drivers should avoid using this register unless they - * need to guarantee that the FIFO is completely drained. It - * is overkill for performing a sync-to-fence. Older drivers - * will use this register for any type of synchronization. + * Guest drivers can also do a partial Legacy Sync to check for some + * particular condition, for instance by stopping early when a fence + * passes before BUSY has been set back to FALSE. This is particularly + * useful if the guest-driver knows that it is blocked waiting on the + * device, because it will yield CPU time back to the host. * * SVGA_FIFO_BUSY -- * - * This register is a fast way for the guest driver to check - * whether the FIFO is already being processed. It reads and - * writes at normal RAM speeds, with no monitor intervention. - * - * If this register reads as TRUE, the host is guaranteeing that - * any new commands written into the FIFO will be noticed before - * the MKS goes back to sleep. + * The SVGA_FIFO_BUSY register is a fast way for the guest driver to check + * whether the device is actively processing FIFO commands before writing + * the more expensive SYNC register. * - * If this register reads as FALSE, no such guarantee can be - * made. + * If this register reads as TRUE, the device is actively processing + * FIFO commands. * - * The guest should use this register to quickly determine - * whether or not it needs to wake up the host.
