AncientOS 4.0 20200926 Unofficial Polaris Build

Device Specific Changes:

• Etude kernel: Op.10 No.3
  • Linux 4.9.237 and CAF tag “LA.UM.8.3.r1-08500-sdm845.0”
  • built with the latest Clang 12 using ThinLTO
  • wireguard 1.0.20200908
  • fingerprint: use qcom drm notifier instead of the generic Linux one
  • some upstreams on mm, arm64, and libs
• Reworked screen panel backlight
  • in previous builds
    • adjusting brightness slider in the lower range resulted in uneven brightness transition
    • previous builds did not allow screen to dim to the lowest possible value
    • auto-brightness had slow reaction to ambient light changes
  • patched frameworks/base to use linear brightness slider instead of the log scale one
  • ported gamma-linear conversion to light HAL
  • re-calculated auto brightness curve to fit new light HAL changes
  • reduced light sensor debounce time to stay in-line with MIUI
  • the result:
    • smooth backlight brightness transition when moving brightness slider
    • screen can dim to the lowest possible value the panel allows
    • auto-brightness reacts faster to ambient light changes
    • auto-brightness is no longer jumpy
    • screen dimming caused by no user action has proper transitions
• cleaned up Google specific hints from powerhint
• created dummy perfd client so that proprietary perfd blobs can be removed while keeping goodix fingerprint sensor functioning
• disabled kpi_optimize in audio extension because it tries to call perfd and spams logs when failed
• re-introduced an updated qti-telephony-common injection to polaris
• dropped wifi-ext
• cleaned up unused auto brightness values
• updated firmware and vendor from MIUI 12 Global Stable V12.0.1.0
• Updated APNs for Chinese carriers
• Bumped Vulkan feature level to 1
• Enabled unspecialized app process pool
• fixed a few sepolicy issues for sched_boost and sysfs_batteryinfo
