sof-solana-gossip

sof-solana-gossip is the vendored gossip backend used by SOF's optional gossip-bootstrap path.

This page is mostly maintainer-facing. External users usually only need it when debugging the bootstrap backend or understanding low-level gossip tuning behavior.

Why It Exists In This Repository

SOF needs tighter control over gossip runtime behavior than the stock upstream package exposes.

The vendored backend makes room for:

  • explicit queue-capacity controls
  • worker-count tuning
  • CPU pinning for gossip threads
  • SOF-specific tuning and telemetry
  • the lighter default duplicate and conflict path used by SOF

Who Should Care

  • operators using gossip-bootstrap
  • contributors changing runtime gossip behavior
  • anyone debugging queue pressure or control-plane traffic inside the bootstrap path

If you are only using direct UDP or processed providers, you can mostly ignore this crate.
