⚡ Bolt: Batch producer wakeups in NAPI poll loop - #42
Conversation
Moved the producer wakeup call (`nata_wake_tx_peer`) outside of the ring buffer spinlock in the NAPI poll loop (`nata_poll`). This reduces lock contention and delays the consumer, increasing throughput. Co-authored-by: maxugly <64644401+maxugly@users.noreply.github.com>

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity.

💡 What: Moved the producer wakeup call (
nata_wake_tx_peer) outside of the ring buffer spinlock in the NAPI poll loop (nata_poll), using a boolean flag to track if a wakeup is needed.🎯 Why: Calling
netif_wake_queueinside a hotpath spinlock causes unnecessary lock contention and delays the consumer, reducing overall throughput.📊 Impact: Reduces lock contention overhead on the producer/consumer ring buffers, increasing throughput for the virtual SATA interface.
🔬 Measurement: Simulated benchmark tests and kernel module compilation.
