/* Development */

I do not own a Poco F1.

This was developed by sharing most of the bits from my OnePlus 6 and Razer Phone 2 kernel.

I won't be doing device-specific changes to this kernel(e.g. improvements to the touch panel drivers) until I get my hands on an actual device.

This also means this kernel is/will be developed conservatively.

If you're interested in contributing to a fundraiser for me to get a Poco F1, please check post #2.

/* f2fs */

This kernel fully supports f2fs for /data and I encourage everyone to use f2fs with my kernel for better performance.

See here as to why you might want f2fs.

To use f2fs, download zip files from http://arter97.com/browse/f2fs

Flash f2fs_tools_for_twrp.zip from TWRP. This won’t format your /data partition.

This will replace TWRP's f2fs tools with the latest version and pass the correct parameter to mkfs.f2fs, which is necessary.

This needs to be done everytime you enter TWRP, if you want to re-format to f2fs.

After formatting, or flashing a new ROM or an OTA, /vendor’s fstab needs to be changed.

Flash f2fs_fstab.zip to convert fstab to f2fs again. This won’t format your /data partition.

/* Disclaimer */

Your warranty is now void.

I am not responsible for bricked devices, dead SD cards,

thermonuclear war, or you getting fired because the alarm app failed. Please

do some research if you have any concerns about features included in this kernel

before flashing it! YOU are choosing to make these modifications, and if

you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* Instructions */

You can use the zip file to flash the kernel from your existing TWRP recovery.

If you don't have TWRP installed already, you can use the img file to flash the kernel directly from your PC via fastboot.

Both methods will install both kernel and modified TWRP recovery.

You can check if the modified TWRP is installed by looking at TWRP's version name.

It should say "arter97".
