Developers and device maintainers may find it useful to have access to logcat in recovery. This patch set adds the following build flags: TARGET_USES_LOGD - This is an Android build flag that enables logd support. Devices that don't have built in kernel logging to dev/log/* will need this flag for logcat. We'll also use this to include the necessary support files for logd in TWRP. TWRP_INCLUDE_LOGCAT - This enables logcat support in recovery. I pulled the init entries from my HTC One M8 GPE boot.img, so I'm not certain whether these will work for all devices or if they're all necessary. Feedback is welcome. PS2: Use "TARGET_USES_LOGD" instead as this flag already exists, and previous flag was named incorrectly (logd isn't kernel logging) PS3: Start logd service on load_persist_props action, needed for 6.0+ PS4: More info on "TARGET_USES_LOGD" flag as related to liblog compilation can be found at the below links: https://android.googlesource.com/platform/system/core/+/android-6.0.1_r10/liblog/Android.mk#27 https://android.googlesource.com/platform/system/core/+/android-6.0.1_r10/liblog/Android.mk#50 Whether or not this flag is needed for logcat in TWRP is dependent on whether liblog was compiled with this flag. PS5: Update commit message to better describe "TARGET_USES_LOGD" flag PS6: Another commit message update Change-Id: Iaac6c6c822dc93fbe4b6eadcf24eef6995dd6b50
