#29 done proper — replaces #33's stale-baseline attempt

PR #33 generated per-series mirrors via git format-patch fe73571..cleanups without first rebasing cleanups onto the v7.0-danctnix1 kernel baseline. Result: per-commit diffs carried stale baseline context (e.g. from_timer rather than timer_container_of API), so the cumulative no longer applied cleanly. pkgrel=6 build #1 failed with Hunk #3 FAILED in Patch D's sta.c.

This PR replaces the broken per-series patches with rebased versions:

Mechanism

  1. In marfrit/bes2600-dkms:
    • danctnix-sync branch: fe73571 + drop-in replace bes2600/* with v7.0-danctnix1's drivers/staging/bes2600/*.
    • cleanups-rebased-on-danctnix: git rebase --onto danctnix-sync fe73571 cleanups. Manual conflict resolution preserving each commit's intent + the new baseline context.
    • bh-c-fossil-cleanup-rebased: same treatment for Patch H.
  2. git format-patch danctnix-sync..cleanups-rebased-on-danctnix --no-merges.
  3. Path-rewrite via sed (bes2600/foo.c → drivers/staging/bes2600/foo.c).
  4. Drop into the same series-dir names as PR #33 (overwriting the broken files).

Functional verification — pkgrel=6 on ohm 2026-05-19 23:39

  • uname -r: 7.0.0-danctnix1-6-pinetab2-danctnix-besser ✓
  • srcversion: 1A919EED0E6DC2478559B17 ✓ (matches the build artifact)
  • bes2600_btuart.ko loads ✓ (proves chardev utility symbols correctly exported)
  • Pattern A (wsm_generic_confirm 0x0007) count: 0 ✓
  • WARN/BUG count: 0 ✓
  • wlan0 associated to newton 2.4 GHz ✓

srcversion differs from pkgrel=5's BEB625FA7443171EA8D55F7 — not byte-equivalent (the chardev re-add chose slightly different formatting than the original danctnix code). Functional equivalence verified on hardware. Byte-equivalence is not a goal of #29; per-series traceability + working kernel are.

Per-fix revertability now real

Removing an include from fleet/ohm.yaml drops that fix from the cumulative. Bisecting on kernel-agent side becomes practical. The four prior cumulative-c5x-danctnix/-shaped builds collapsed the entire bes2600 driver scope into one opaque blob — that's gone now.

Companion

  • marfrit/bes2600-dkms: branches danctnix-sync, cleanups-rebased-on-danctnix, bh-c-fossil-cleanup-rebased pushed for traceability (source of the format-patch output).
  • marfrit/marfrit-packages: pkgrel=6 with the new cumulative b2sum landed on main directly (commit 31da35a54) since the build was hardware-verified.
  • kernel-agent retains cumulative-c5x-danctnix/ on disk as bisection reference — still excluded from fleet/ohm.yaml.

Closes (proper this time): #29.

patches/driver/bes2600/*-danctnix + arch/arm64/scs-...: rebased on danctnix baseline (#29 redo) b04c8cd501 
PR #33's per-series mirrors were generated against the bes2600-dkms
cleanups branch (rooted at fe73571) without rebasing onto the
v7.0-danctnix1 kernel baseline. Result: per-commit diffs carried
stale baseline context (e.g. from_timer rather than the new
timer_container_of API), so the cumulative no longer applied cleanly
to ohm's actual base. pkgrel=6 build #1 failed with 'Hunk #3 FAILED'
in Patch D's sta.c.

Fix: in marfrit/bes2600-dkms, create danctnix-sync branch
(fe73571 + drop-in replace bes2600/ with v7.0-danctnix1's
drivers/staging/bes2600/), rebase cleanups onto it as
cleanups-rebased-on-danctnix, manually resolve the resulting conflicts
keeping each commit's intent + the new baseline context, rebase
Patch H accordingly. Format-patch and re-route to the same series-dir
names as PR #33.

Conflict resolution notes:
- 'remove userspace /dev/bes2600 character device interface' commit:
  the chardev wrapper was removed but two utility funcs that danctnix's
  bes2600_btuart.c depends on (bes2600_chrdev_is_bus_error,
  bes2600_chrdev_switch_subsys_glb) were re-added with EXPORT_SYMBOL_GPL.
  bes2600_switch_bt re-added as static (file-local, called only from
  bes2600_chrdev_switch_subsys_glb).
- Patch D (atomicize ba_lock): re-resolved bes2600_ba_timer's
  timer_container_of() vs from_timer() to keep the new API.
- SCS Makefile @@ hunk counts corrected from -9,6 +9,10 to -9,6 +9,11
  (the original was actually wrong; build-via-fuzz was masking it).

pkgrel=6 built from this manifest + installed on ohm 2026-05-19 ~23:39.
Functional verification: bes2600 + bes2600_btuart both load, Pattern A
0 over fresh boot, wlan0 associates to newton. srcversion
1A919EED0E6DC2478559B17 differs from pkgrel=5's BEB625FA... — the
reconstruction is functionally equivalent (5 GHz working, no
firmware/driver race conditions) but NOT byte-equivalent (the chardev
utility re-add chose different formatting than the original danctnix
code). Byte-equivalence is not a goal; per-series traceability and
working hardware are.

Closes (proper this time): #29.
Refs: #28, #30, #33 (the half-working attempt), #31, #32.

Closing without merge — the per-series reconstruction this PR shipped (a redo of #33) was found to wedge the bes2600 chip under sustained load.

What happened

  1. pkgrel=6 from this branch built + booted clean (verified ~10 min uptime).
  2. After 1–6h of real-world use, the chip enters a bes2600_chrdev_wifi_force_close → tx_loop_set_enable WARN_ON → bes_sdio_memcpy_io_helper err=-110 → startup timeout!!! cascade. Chip wedges until reboot.
  3. Same cascade observed in both production pkgrel=6 (6h15m run, wedged at 5:53:56) and pkgrel=6-lockdep (1h45m run, wedged at 07:41:42).
  4. The pkgrel=5 c5x-interim cumulative does NOT exhibit this regression — sustained multi-hour runs are clean.

Likely root cause

The rebase-onto-danctnix-baseline conflict resolution I did for the remove-chardev-user-interface commit re-added bes2600_chrdev_switch_subsys_glb, bes2600_chrdev_is_bus_error, and bes2600_switch_bt to make bes2600_btuart.ko link. But the c5x-interim hand-curated cumulative kept a SLIGHTLY DIFFERENT set of internal-helper survivors in bes_chardev.c, including the specific state path that bes2600_chrdev_wifi_force_close relies on. My re-add doesn't match the c5x-interim's recovery-path invariants.

Functional equivalence at ~10 min uptime missed this — needed N-hour stress to surface.

Actions

  • ohm rolled back to pkgrel=5.
  • marfrit-packages pkgrel=6 commit reverted (2299d7a02).
  • kernel-agent main reverted PR #33 (the predecessor of this PR) — commit 588350c. fleet/ohm.yaml is back to using cumulative-c5x-danctnix/.
  • A besser issue will be filed documenting the regression so future per-series reconstruction work has a stress-test acceptance criterion.

Salvageable

The rebased branches in marfrit/bes2600-dkms (danctnix-sync, cleanups-rebased-on-danctnix, bh-c-fossil-cleanup-rebased) stay around — most of the conflict resolutions ARE correct, only the chardev re-add needs to be redone to match c5x-interim's exact helper set. The series-dirs in claude-noether/kernel-agent:noether/kernel-agent-29-rebased-on-danctnix-clean also stay until a redo branch supersedes them.

#29 stays open.
