quick kernel release


Features

Most notable changes
  • upstream Android binder with big lock removed, higher throughput
  • overall smoother UI
  • several bug-fixes
  • thermal-driver/"engine" rework - this should keep the device cooler and smoother, more fine-tuned throttling & hotplugging
  • msm_performance, cpu-boost & enhanced core_ctl ("stock" seems to offer best experience)
  • choice between several governors (for CPU)
  • underclockable GPU with lower frequencies for graphics card
  • additional performance enhancements
  • wakelock blockers included
  • finer-grained (lower latency) scheduler
  • FauxSound - so you need to tune down AMP to reduce (possible) white noise, this also depends on sound libraries and installed ROM
  • stripped down kernel - less bloat
  • reworked & enhanced RCU
  • powerefficient workqueues used to reduce battery consumption
  • forcing of most kthread to little core to reduce battery consumption
  • workqueue enhancements & reliability improvements
  • several changes to cut down latency / lag
  • WireGuard support
  • enhanced & improved random driver for more reliable entropy generation (less stutter, lags; better security)
  • scheduler enhancements to cut down idle battery drain
  • security hardening - enhanced security and lots of unneeded drivers/features removed
  • countless other changes

Flashing and testing
How can i tune down the amp?(as you mentioned in changelog)
Click to expand...
Click to collapse

headphone amp - I use EX Kernel Manager, Kernel Adiutor does NOT work [does nothing], not sure if Faux Sound Control works

or via console and changing values at /sys/ ... dunno - haven't tried that way yet

Just plug and play ?

---------- Post added at 07:17 PM ---------- Previous post was at 07:11 PM ----------

Great job done it's so close to perfection!
Performance is great even though thermals are getting high while playing games but there is no throttling ?
Battery life is good (need further testing..)

    2021 September update:

    Since I've been getting requests lately due to Google's updated Google Drive policy - here's the updated share link for the Z5 kernels

    Z5-Kernels - Google Drive

    drive.google.com drive.google.com

    Final notice: Since my Z5 died (it's broken into pieces, glass shattered) - development is effectively halted - NO more updates - sorry

    This is a Stock (Sony) ROM Kernel and WILL NOT work on AOSP, CM, etc.

    aka SunKernel for Z5 + Z5 Dual - Stock ROM (for now only stock)

    Alright guys,

    this is my intermediate result on working on the Kernel for the Z5 (e6653, sumire), which I'm currently using

    There's now also a Kernel for the dsds (Dual Slot/Sim) Version (E6633/E6683), but I can't test if it works due to lack of that very device - Enjoy !


    Keep in mind that building for the Z5 "Stock" ROMs and "Stock" Kernels, you're constantly facing the following tradeoff:

    • compatibility with pre-built "core" kernel modules (e.g. texfat [proprietary exfat microSD fs driver])
    • compatibility with pre-built "goodies" kernel modules (e.g. video and other acceleration, hwcodecs, ...)
    • losing features that can NOT be replaced by similar ones (e.g. ecryptfs, wlan, exfat, etc.)
    • when going too far the device doesn't boot or simply hangs on bootanimation

    this resulted in a couple branches (at least several dozen) that are partially or totally broken :silly:

    [snip]
    ...
    [snip]





    More info on the Latest Kernel can be usually found at:

    AT the end of the thread

    ( I KNOW - I should have reserved a few posts for better overview :( )

    All other features, things should work - no guarantees


    Before starting to test/use keep in mind that this is WIP (work in progress),

    that means - NO guarantees,

    backups before flashing are a MUST (especially your microSD card content !)

    stability, speed, improved battery and satisfaction are a great side-effect to have.

    You have been WARNED !


    Enjoy ! :)

    305_corona_III.1_9_12_5_2_ctl_X
    253_corona_III.1_9_4_2 ["stable" branch]

    This is an interim build which could/should solve several problems

    Changes:
    305_corona_III.1_9_12_5_2_ctl_X
    - msm: thermal: load scaling was reverted (this should make thermal behavior less erratic and more predictable)
    - much faster /proc/vmstat (mostly used in Kernel Adiutor first tab & others)
    - random: 64 & 128 default values restored
    - CVE-2016-5696 fix re-added since random depletion now seems to be avoided, no slower down anymore during longer usage (?)
    - slim-msm: sleep while device-timeout (better battery savings, more reliable operation)
    - GPU: disable POPP [Power Optimizer Push-Pop] - unfortunately too laggy
    - GPU: re-add conversion of some workqueues to kthreads, now it doesn't cause micro-lags anymore
    - revert: asynchronous resume threads (potentially unstable)
    - TONs of fixes (i2c, ion, crypto, camera, sound processing, bluetooth [?], tcp, block, hid, ipa, mdss, evdev, memcg, memory-hotplug, ipv6, spmi, smd, cpuidle, usb)
    - sps: fix kernel panic (fix hang/reboot/not waking up from sleep)
    - block: make it possible to delete files again that previously were impossible to be deleted
    - sched: fix task-priority when using SCHED_RESET_ON_FORK
    - add branch instruction count (potentially significantly better performance)
    - power: qpnp-fg: use powerefficient workqueues (potentially MUCH LESS battery consumption)
    - soc: qcom: bam_dmux: fast-shutdown flag [supported ?], (potentially much faster shutdown of modem and MUCH more energy savings)
    - arm64 optimized variant of crc32: 30-450% speed improvement [EXPERIMENTAL, might break encrypted phone function], could speed up the phone in certain areas A LOT
    - input: make volume keys work while device is in sleep-mode since starting with MM that might not work anymore


    253_corona_III.1_9_4_2
    - 253_corona_III.1_9_4 based (supposedly more stable kernel)
    - make Safetynet work
    - fix DirtyCOW: preventing others (non-authorized users/apps) from obtaining root privileges
    - fuse: fix infinite loop (mostly for (t)exfat microSD exfat driver and all others being bound/mounted via fuse)
    - workqueue: allow rescuer thread to do more work

    Notes

    battery life said:
    This kernel is giving me horizontal standby lines after usage & while in Airplane mode,

    this means: most of the kernel-side issues relating to battery efficiency and wakelocks should be fixed. (why wasn't it like that out of the box ? :confused: )


    If your device doesn't go to sleep it's due to wakelocks, alarms and services keep it awake

    Important Notes:

    Do NOT restore previous settings of Kernel Adiutor, Kernel Adiutor Mod, EX Kernel Manager, etc.

    since that might lead to crash of thermal engine !

    Also do NOT use BOTH core control + temperature throttle for "Thermal / Thermal Engine"

    Enjoy ! :)

    SunKernel_for_Z5 253_I.1_2_12


    224_I.1_2_12 Changelog said:
    Changelog:

    • ramdisk change/bump to AndroPlus v33 (224 kernel)
    • ramdisk change/bump to AndroPlus v33 (253 kernel)
    • (due to unknown errors/reasons the process AndroPlus uses to create and modify his ramdisk appears to work better, thus using that)
    • (thanks to @AndroPlus)
    • .
    • significant battery runtime improvements are to be expected
    • during bootup ony the small core cluster is active == cooler bootup, but potentially also slower (it should however be fast enough)
    • Overclocking: active after Boot for BIG core 2.0 GHz, little core 1.63 GHz , adjust with Kernel Adiutor, etc.
    • <-- experimental, if it locks up during setup/bootup (e.g. wiping dalvik cache and re-creating cache), please let me know
    • .
    • "HOTFIX": reverted experimental bluedroid wakelock control - this should prevent lockup during bluetooth usage and accidental activation
    • filesystem buffer increased LRU size
    • task's adj rbtree for LMK (low memory killer - much more efficient during high memory load)
    • usb-gadget functionality
    • android keyboard support
    • some smoothness tweaks for interactive governor/in general; kudos to @auras76
    • fastcharge support (not sure if this has an actual effect, it seemed to have charged my phone faster ?, dunno)
    • dynamic fsync
    • optional input boost (input boost control), optimized input boost for little cores only (do not boost for big cores)
    • setting to tweak throttling temperature
