ASB-V23

🚀 AutoSystemBoost V23 MAJOR RELEASE

Compared to V22 | Date: 2026-03-15

🌟 What Changed in V23

ASB-V23 is not a maintenance patch on top of V22.
It is the release where AutoSystemBoost evolves from a session-aware adaptive governor into a session-intelligent runtime with persistent memory, recovery discipline, and a modular architecture.

V22 = first session-intelligent high-load governor release
V23 = first self-learning, recovery-aware, architecturally clean release

🧠 Session Intelligence — Time-to-First Metrics

V23 answers the question V22 could not: how fast does this session actually break down?

Metric	V22	V23
Time to first SUSTAINED	❌	✅ ses_t2s — seconds from reset to first SUSTAINED
Time to first thermal collapse	❌	✅ ses_t2thermal — seconds to first thermal-triggered SUSTAINED
SUSTAINED quality score	❌	✅ ses_efficiency — 0–100 score per session
Thermal collapse counter	❌	✅ ses_recovery — counts how many times thermal collapsed

What ses_efficiency measures

efficiency = 100 - gap_penalty - temp_penalty
  gap_penalty  = avg_gap_p0 / 15000  (capped at 50)
  temp_penalty = (max_temp - 55) × 2  (capped at 50)

• 100/100 = SUSTAINED at moderate temperature with small cap gap (useful throttle)
• ~50/100 = deep thermal wall, heavily throttled
• < 30/100 = system was too hot and too throttled to be effective

Logged on every SUSTAINED exit:

exit_sustained: temp_dropped t=53°C → HEAVY cooldown=30s efficiency=87/100

💾 Persistent Session Memory

V23 introduces the first cross-session memory in ASB history.

	V22	V23
Session history	Resets on every restart	Persists across runs
History file	None	/dev/.asb/session_stats.json
Rolling average	None	EMA across last 10 sessions

What is stored

{"count":5,"t2s":95.0,"t2th":95.0,"temp":68.0,"gap":0.0,"eff":95.0}

Field	Meaning
count	Number of sessions accumulated
t2s	Rolling avg seconds to first SUSTAINED
t2th	Rolling avg seconds to first thermal collapse
temp	Rolling avg peak temperature °C
gap	Rolling avg GAMING cap gap kHz
eff	Rolling avg sustained efficiency score

Shown in diag log at every governor startup:

persistent stats: sessions=5 avg_t2s=95s avg_temp=68°C avg_gap=0 avg_eff=95

Visible in asb status:

hist_sessions, hist_t2s, hist_temp, hist_gap, hist_eff

🔁 Recovery Discipline

V22 had cooling and retry cooldowns. V23 adds recovery intelligence: after the chip has already collapsed twice in the same session, GAMING retry becomes more conservative automatically.

Condition	V22	V23
After 1st thermal collapse	retry after cooldown	same
After 2nd+ thermal collapse	same retry threshold	temp_max reduced by 5°C

/* Recovery discipline: ses_recovery_count >= 2 → stricter temp gate */
if (temp_max > 0 && fsm->ses_recovery_count >= 2)
    temp_max -= 5;

This means: if the session has already shown that the chip overheats under GAMING load, ASB stops trying to re-enter GAMING until the chip is 5°C cooler than normal. No config needed — fires automatically.

🔋 Battery Branch — Active Improvements

V22 introduced the battery governor mode. V23 makes it smarter based on real device data.

Problem observed in testing

On screen wake from DEEP_IDLE, load spikes to 12–21 immediately (Android system overhead). With V22's heavy_load_enter=2.0, the governor jumped to HEAVY within 4 seconds of every screen-on event, defeating the purpose of the battery profile.

Fix: bat_heavy_load_enter

	V22	V23
HEAVY threshold in battery	2.0 (global)	4.0 (battery-specific)
Screen wake behavior	HEAVY in 4s	Stays in LIGHT_IDLE through wake spike
Config key	❌	bat_heavy_load_enter=4.0

Battery params now wired (were config-only in V22)

Parameter	V22	V23
bat_fast_idle_s=15	Stored in config, unused	Active: LIGHT_IDLE → DEEP_IDLE in 15s
bat_light_idle_gpu=10	Stored in config, unused	Active: GPU capped at 10% in LIGHT_IDLE

Both fields were declared in V22 but never connected to the FSM. Now wired.

🎯 Profile-Aware highload_mode

V22 required manually setting highload_mode in governor.conf.
V23 ties it to the active profile automatically.

Profile switch	V22	V23
→ performance	No change to highload_mode	burst applied automatically
→ battery	No change to highload_mode	burst cleared if active
→ balanced	No change	No change (respects config)

What burst means for performance profile:

gaming_gap_ticks          = 3    (was 4)
gaming_retry_cooldown_s   = 20   (was 30)
gaming_retry_temp_max     = 50
sustained_level           = 0.85 (was 0.80)
sustained_reentry_cooldown_s = 10 (was 20)

Logged on profile switch:

profile:performance → highload burst applied
profile:battery → highload burst cleared

🏗 Architecture — Modular Shell Layer

V22 had a monolithic service.sh (1463 lines) that was the single point of failure for the entire module.

V23 splits it into focused modules:

File	Role	Lines
service.sh	Boot orchestrator, sources modules	~1150
runtime/asb_utils.sh	Profile vars, governor lifecycle	178
runtime/asb_reconcile.sh	Profile drift correction loop	110
runtime/asb_watchdog.sh	Governor process watchdog	35

Why runtime/ not common/

MMT installer (functions.sh) runs rm -rf $MODPATH/common after installation. Files in common/ are for install-time only and are deleted before service.sh ever runs. V23 places persistent runtime files in runtime/ which survives the install cleanup.

Watchdog threshold fix

	V22	V23
Stale state threshold	90s (caused 3–4 restarts/hour)	240s
Root cause	DEEP_IDLE never writes state unless caps change	Keepalive write every 60s

---

🔊 Audio Fix — Spatial Audio / 3D Audio

OnePlus 3D Audio (Pространственное аудио) buttons were non-functional in V22.

Property	V22	V23
ro.audio.spatializer_enabled	false	true
ro.audio.spatializer_binaural_enabled_default	false	true
ro.audio.spatializer_transaural_enabled_default	false	true

All three modes now work: Fixed, Head tracking, and Off.

⚙️ Profile Tuning (V22 → V23)

performance.sh

Parameter	V22	V23
SCHED_RATE	1000	800
SCHED_UP_RATE	400	300
SCHED_DOWN_RATE	1500	1200
SCHED_HISPEED_LOAD	65	60

Faster CPU ramp-up response for performance workloads.

balanced.sh

Parameter	V22	V23
WALT_TOPAPP_WEIGHT	105	110
WALT_BOOST_MIN_UTIL	51	48
SCHED_RATE	3000	2500
SCHED_UP_RATE	1200	1000
SCHED_DOWN_RATE	4000	3500
SCHED_HISPEED_LOAD	—	85
GPU_IDLE_TIMER	—	64

Improved foreground app responsiveness, smoother GPU idle transitions.

battery.sh

Parameter	V22	V23
WALT_TOPAPP_WEIGHT	60	65
WALT_BOOST_MIN_UTIL	140	150
UCL_TOP_MAX	16	18

Slightly higher foreground responsiveness in battery mode without sacrificing idle efficiency.

All other V22 parameters remain unchanged and compatible.

🛠 Bug Fixes

Bug	Impact	Fix
bat_fast_idle_s and bat_light_idle_gpu were dead config fields	Battery LIGHT_IDLE had no GPU cap, no fast idle	Wired into FSM interpolation
bat_deep_idle counter always 0	Battery telemetry useless	fsm_profile_is_battery not set on socket-initiated profile switch — fixed
runtime/ files deleted by installer	governor crashed on boot (common/ wiped)	Moved to runtime/ which survives MMT cleanup
Watchdog killed governor every 5–16 min during DEEP_IDLE	3–4 unnecessary restarts per hour	State keepalive write every 60s
Watchdog threshold 90s too aggressive	Killed governor during normal DEEP_IDLE	Threshold raised to 240s
Spatial audio buttons non-functional	OnePlus 3D Audio settings had no effect	Three ro.audio.spatializer_* props set to true

✅ V23 Summary

✔ Session intelligence — ses_t2s, ses_t2thermal, ses_efficiency, ses_recovery
✔ Persistent session memory — rolling EMA across 10 sessions in /dev/.asb/session_stats.json
✔ Recovery discipline — stricter GAMING retry after 2+ thermal collapses
✔ Battery intelligence — bat_heavy_load_enter=4.0 prevents spurious HEAVY on screen wake
✔ bat_fast_idle_s and bat_light_idle_gpu now active — were config-only in V22
✔ Profile-aware highload_mode — burst auto-applied on profile:performance
✔ Modular shell architecture — runtime/ layer, service.sh -313 lines
✔ Watchdog stability — 90s → 240s threshold + 60s keepalive

✔ Profile tuning — all three profiles refined from real device data

V23 makes ASB remember what happened, understand why it happened, and behave differently next time.
