An extremely low latency KVMFR (KVM FrameRelay) implementation for guests with VGA PCI Passthrough.

This is rare and I'm not sure what causes it, but PipeWire sometimes uses a larger period size than requested for no obvious reason (e.g., we could request a period size of 512, but PipeWire uses 2048 anyway). This causes us to stay in a permanent state of underrunning because the target latency is too low. With this change, we use the actual device period in the target latency calculation if it is larger than the expected maximum. We may still get some glitches at the beginning of playback (because the startup latency is based upon the expected maximum period size), but it will recover after a few seconds as it adjusts to the new target latency. |
