PixelExperience 11.0 20210119-0213 Official Polaris Beta Build

Etude kernel optimizations, Snap camera, iwlan legacy mode, QTI BT stack, oss libwfdaac_vendor, January security patch, AR crash fix, and SafetyNet pass!

Device Specific Changes:

  • Etude kernel: Op.11 No.2
    • Linux 4.9.252
    • merged CAF tag LA.UM.9.3.r1-00500-sdm845.0 into kernel
    • sched: restricted iowait boost to foreground and top-app tasks so that background I/O does not boost cpu frequency unnecessarily
    • cpufreq: fixed incorrect average capacity calculation
    • limited sched{up,down}migrate tunables to values between 0 and 100
    • backported arm64 optimized assembly routine from mainline kernel: NEON accelerated XOR implementation, faster checksum, consistently enabling crc32 extension, and bug fixes in copy
    • use atomic update for clkgate_enable so that frequent toggling from power hint does not cause a timeout
    • use WQ_HIGHPRI for UFS gating work
    • minimized qos remap updates in sde plane
    • updated sdFAT to 2.4.5
    • inlined spinlock function family
    • DO NOT use a third party kernel without proper support for Pixel thermal hal
  • Allow manually configuring the APN when using China Unicom
  • Shipped Snap camera app
  • Enabled iwlan legacy mode
  • Switched to QTI BT stack
    • aptX tws+ codec support is back
  • Built libwfdaac_vendor from source

Feature Update Highlights:

  • January security patch
  • Fixed crashes on AR Core
  • SafetyNet should pass again

Gapps are included. Vendor and firmware are included. Dirty flash or incremental updates should be fine if you are on my previous PE 11 build.
