init.common.rc: Set /sys/kernel/debug/tracing permissions cherry-picked from https://android-review.googlesource.com/c/1345439 CONFIG_DEBUG_FS is enabled in android-mainline kernel, https://android-review.googlesource.com/c/1324220, but /sys/kernel/debug/tracing permissions are not getting set in system/core/rootdir/init.rc's existing "on late-fs" trigger, which resulted in webview crash on db845c. F webview_zygote: jni_internal.cc:649] JNI FatalError called: (zygote) \ Failed open(/sys/kernel/debug/tracing/trace_marker, 1): Permission denied ----->8-----snip-----8<----- F DEBUG : signal 6 (SIGABRT), code -1 (SI_QUEUE), fault addr -------- F DEBUG : Abort message: 'JNI FatalError called: (zygote) Failed open(/sys/kernel/debug/tracing/trace_marker, 1): Permission denied' This webview crash can be reproduced with stock AOSP webview version "74.0.3729.186", as well as version "85.0.4150.0" built locally. Here is a temporary workaround to set the permissions on boot completion, while we debug it further.

IMPORTANT NOTICE --> UNLOCKING AND ROOTING MAY VOID YOUR PHONE WARRANTY AND MAY BRICK YOUR DEVICE AS WELL. I'M NOT RESPONSIBLE FOR EITHER OF THAT.
Here is a reasonable guide to get you started on unlocking and rooting Poco F1 --> https://forum.xda-developers.com/poco-f1/how-to/xiaomi-poco-f1-unlock-bootloader-custom-t3839405
Just for the records I downloaded and installed following external packages to unlock and root my device-->
Also Dont forget to take a backup of your images from TWRP and copy them to your Host machine. It will come very handy. Believe me :)
mkdir aosp-repo cd aosp-repo repo init -u https://android.googlesource.com/platform/manifest -b master git clone git@github.com:pundiramit/android-local-manifests.git .repo/local_manifests -b master repo sync -j$nproc source build/envsetup.sh lunch aosp_beryllium-userdebug make -j$nproc
NOTE: To get display working on PocoF1, we need supported Adreno firmware binaries, otherwise PocoF1 will not boot to UI.
Adreno binaries are shipped with non-distributable license,
hence I'm not shipping them in my build setup. You can
extract Adreno a630_* firmware binaries from a working
device build. I extracted mine from
lineage-16.0-20190612-nightly-beryllium-signed.zip ;)
Then copy the binaries to out vendor directory
i.e. out/target/product/aosp_beryllium/vendor/firmware,
and run "make -j$nproc" to create vendor.img again.

Delete all objects in aosp-repo/device/xiaomi/beryllium/prebuilt-kernel/android-mainline/ then copy build artifacts from kernel-repo/out/android-mainline/dist/ to aosp-repo/device/xiaomi/beryllium/prebuilt-kernel/android-mainline/ build AOSP images again.
cd aosp-repo source build/envsetup.sh lunch aosp_beryllium-userdebug make TARGET_KERNEL_USE=mainline -j$nproc
Now flash and boot AOSP images again with your custom kernel.
