Sonnet (general-purpose subagent, model=sonnet) reviewed
~/src/besser/bes2600-dkms-mobian/bes2600/ given the Phase 0 measurement
context. Output: 8-item ranked restructuring map, file:line cited.
Headline:
- Item 1: collapse sdio_rx_work relay into BH loop (~5x workqueue
dispatch reduction, medium effort)
- Item 2: batch deliver via ieee80211_rx_list (small effort, removes
per-frame softirq)
- Items 1 + 2 together collapse "9 workqueue events per delivered
frame" to ~1.
Items 3-5 clean up next-layer overhead (TX-side queue_work,
per-frame ba_lock, ps_state_lock under known-dead PSM). Items 6-8
are follow-ons to be re-measured after 1-3 land.
Phase 4 plan locking the lead candidate(s) follows in a separate PR.
