repo sync -c -j$(nproc --all) --force-sync --no-clone-bundle --no-tags

Build

• Set up the build environment

. b*/env*

• Lunch a target

lunch lineage_codename-bp2a-user

• To start compiling

m lunaris

• Bringup about (add in device tree settings overlay)

https://github.com/Lunaris-AOSP/packages_apps_Settings/blob/0acd6251e20bacd8db589beb483d6138f553f02c/res/values/lunaris_strings.xml#L338

• Maintainer flag
• Add in system.prop

ro.paranoid.maintainer=GHOST

• Disable blur

TARGET_ENABLE_BLUR := false

• Enable BCR

WITH_BCR := true

Build flages

• GMS

WITH_GMS := true

• Vanilla

WITH_GMS := false

• GMS CORE

TARGET_USES_CORE_GAPPS := true

• GMS OMNI

TARGET_USES_OMNI_GAPPS :=true

• Animation fix for mtk devices

PERF_ANIM_OVERRIDE := true

• refresh rate list (optional) - defining this flags makes the controller skip the parsing of Display.Mode refresh rates
• for supported refresh rates. The refresh rate controller will also assume that all the defined refresh rates are "supported"

TARGET_SUPPORTED_REFRESH_RATES := 60,90,120,144

• Allows charging while keeping the battery percentage fixed. If supported, you must also add a SELinux rule for the input_suspend node and kernel support

BYPASS_CHARGE_SUPPORTED := true

Performance mode

• If your device uses standard labels, add rules like this to your device tree genfs_context:

genfscon proc /sys/vm/dirty_writeback_centisecs     u:object_r:proc_dirty:s0
genfscon proc /sys/vm/vfs_cache_pressure            u:object_r:proc_drop_caches:s0
genfscon proc /sys/vm/dirty_ratio                   u:object_r:proc_dirty:s0
genfscon proc /sys/kernel/sched_migration_cost_ns   u:object_r:proc_sched:s0
genfscon proc /sys/kernel/sched_pelt_multiplier     u:object_r:proc_sched:s0

• GPU boost
• To allow boost framework to access your device gpu nodes, add genfs context for your node and label it as sysfs_gpu

genfscon sysfs /devices/platform/1c500000.mali/available_frequencies                   u:object_r:sysfs_gpu:s0
genfscon sysfs /devices/platform/1c500000.mali/hint_min_freq                           u:object_r:sysfs_gpu:s0

• SEPolicy conflicts
• If your device uses different OEM labels (common on MediaTek or Qualcomm), add allow rules instead of relabeling.

allow init proc_vm_dirty:file rw_file_perms;
allow init proc_dirty_ratio:file rw_file_perms;

Lockscreen cpu info fix

• Add in systemui configs.xml
