    Changelog

    2020-07-01
    • Linux Upstream to 4.14.187
    • reworked gpu freq table and busclocks
    • bring back the smoothness ;)


    2020-06-30
    • CPU is going down to 300MHz at silver cluster
    • GPU step 156MHz -> 177MHz because of a bit laggy scrolling
    • backport binder from 4.19
    • more optimized sched logic
    • speedup network
    • accelerated NEON
    • more battery savings
    • more RCU patchwork
    • added NTFS and MSDOS Filesystems
    • removed more debug and logging
    • compiler optimizations
    • removed wireguard - don't need/use it

    2020-06-28
    • fixed gpu clock setting at boot
    • added new gpu freq step (156MHz) for batterysaving as idle
    • set lower cpu cluster min freq as default
    • unlock the max cpu freq steps from SD855
    • some voltages reduced and busrates fixed (more batterysaving)
    • optimized memcmp
    • bring back touchboost
    • added multiple little patches

    2020-06-27
    • Linux Upstream to 4.14.186
    • wireguard update
    • disable touchboost at boot - can be enabled in Kernel Manager (we don't need this, our p4 is fast enough)

    • better deepsleep
    • reworked rcu
    • patched sched
    • removed FRAME POINTER
    • removed AUDIT
    • removed some log spam

    • clean build after rebase - only 1 version to match batterylife and performance
    • clang update

    2020-06-22
    • Linux Upstream to 4.14.185
    • multiple fixes and patches
    • removed some logging, tracing and debug

    I tested it for almost a day, very snappy but somehow (could be coincidence) battery took a hit, discharged to 43% with only 2:20 h SOT. Usually at home with that usage it should be around 50-55%. But latest linux and speed are good, will keep trying (Google Play Services coincidence, signal etc)

    please look in kernel manager and set gpu freq on your own. sounds like they stuck on max.
