Kernel extensions. A new kernel.sh covers the areas this module had not touched: devfreq bus and memory-controller clocks, KSM deduplication, transparent hugepages, schedtune boost, the full three-value TCP buffers, touch boost, and the filesystem ceilings (inotify, file-max, nr_open). Each section has its own switch and all of them are off by default.

Config versioning. Config writes now go through a temp file and an atomic rename rather than sed -i, so an interrupted write can no longer leave a half-written file. There is a SCHEMA field and a migration path that fills in new keys on existing installs without disturbing what is already set.

SELinux. The module now ships sepolicy.rule with 184 rules covering the nodes it writes. Previously some writes could be silently blocked on enforcing devices.

Watchdog. watchdog.sh checks autopilot, guard, appwatch and wipeshield every five minutes and restarts anything that died. They used to fail silently.

Also

• periodic TRIM, interval in days
• switch to powersave automatically below a battery level you choose
• dry run now reports what the kernel extensions would change
• WebUI: kernel extension switches, watchdog controls, devfreq listing

Fixed

• safe mode appended SAFEGUARD=0 to the config, creating a duplicate key. It rewrites in place now
• the boot-failure counter was left as an empty file when cleared

Everything from earlier versions is unchanged.

License - the repo now carries the GPL-3.0 text that module.yaml was already claiming.

Custom presets - save your own named profile on top of one of the four built-ins. Names are validated, and you cannot shadow a built-in.

Per-app parameters - a node and value can be bound to a package and written only while that package is in the foreground. Range checking applies. Useful for capping one game's clocks without slowing everything else.

Dry-run preview - before applying anything, ask what would change. It prints every node with its current and target value and writes nothing at all.

Also in this build

• CHANGELOG.md covering every release so far
• English readme, linked from the Chinese one
• a tools tab in the WebUI for backup, presets, per-app parameters and the preview, 9 tabs total

Fixed

• app-revert silently restored nothing: it looked up backups by the unprefixed path while the writer stored them with the KSU_SYS prefix
• the per-app code was initially inserted inside another function and broke the script; custom.sh was rewritten with all functions at top level

Everything from earlier versions is unchanged: four profiles, adaptive switching, charge limiting, app standby management, custom parameters, display tuning, boot-failure rollback, wipe protection and config export/import.

Install through the KernelSU manager under Modules - Install from storage, then reboot.

This build is mostly about the things that were missing rather than new switches on top of old ones.

Config export and import - everything you have configured (options, per-app rules, custom parameters, whitelist) goes into one JSON file on your storage. Import merges rather than replaces, so keys the backup does not contain are left alone. Useful when moving to a new device or sharing a setup.

CPU frequency limits - the profiles used to change the governor and nothing else. They now set scaling_max_freq and scaling_min_freq too, snapped to frequencies your kernel actually advertises. Ranges are 10-45 percent for powersave up to 60-100 for gaming.

Range checking for custom parameters - if a node has min and max files next to it, a value outside that range is refused before it is ever written. There is a force option if you know what you are doing.

LMK and memory pressure - min_free_kbytes scaled by installed RAM, lowmemorykiller minfree per profile, watermark tuning. This is usually the real reason background apps get killed, and it was not covered before.

ZRAM sizing - if zram0 has no size yet it gets 75 percent of RAM, with mkswap and swapon. Existing sizes are left alone.

Thermal zone selection - unlocking thermal no longer disables every zone blindly. You choose which ones, cpu and gpu by default. A new zones command lists every zone with its type, mode and temperature.

Autopilot - follows the system battery saver and can force a profile during a time window, including windows that cross midnight.

Everything from earlier versions is still there: four profiles, adaptive switching, charge limiting, app standby management, per-app policies, display tuning, boot-failure rollback, wipe protection and the WebUI, now with 8 tabs.

Drop the zip into the KernelSU manager under Modules - Install from storage, then reboot.

New in this build:

CPU frequency limits - profiles now set scaling_max_freq and scaling_min_freq, not just the governor. The range is picked from the frequencies your kernel actually exposes, so nothing is hardcoded. Toggle with the CPU 频率上下限 switch.

Boot-failure rollback - the module counts boots. If the system does not come up three times in a row, it rolls back every kernel and custom parameter it changed, writes the disable flag and turns itself off. This is what protects you when a custom parameter turns out to be wrong.

Wipe protection - a new guard with three modes:

• 增强模式: kills the process the moment a wipe command is seen
• 普通模式: pauses and asks you first, through the WebUI
• 不防护: logs only

It watches running processes and boot scripts for rm -rf on system paths, mkfs, dd to block devices, fastboot wipe/erase/format and shred. Temporary paths such as /tmp, /cache and /data/local/tmp are deliberately left alone.

Also: updateJson is now set, so the manager can tell you about new versions.

Everything from before is unchanged: four profiles, adaptive switching, charge limiting, app standby management, per-app policies, custom parameters, display tuning, initrc services and the WebUI.

If you had v3.0.2 installed, uninstall it first. The module id changed from ksu_tuner to
KernelSU-Tuner to match the registered id, so the manager treats them as two different modules.

What changed in this build:

• module.prop and module.yaml now use id=KernelSU-Tuner, matching the registered id
• module paths follow the id, so the module now lives at /data/adb/modules/KernelSU-Tuner
• the initrc file and its service names were renamed to match
• the runtime data directory intentionally stays at /data/adb/ksu_tuner so existing configuration survives

Everything else is unchanged from v3.0.2:

• Four profiles (powersave / balanced / performance / gaming) driving CPU governor, GPU levels, IO scheduler and readahead, VM tunables, network stack, DNS and ZRAM compression
• Adaptive switching based on temperature, screen state and charging, with hysteresis
• Charge limiting with automatic resume
• App Standby Bucket management with a per-app whitelist
• Per-app profiles driven by whichever app is in the foreground
• Custom sysfs and proc parameter editor, every change backed up first
• Refresh rate and touch sampling tuning
• initrc services
• WebUI console, no external dependencies
