Greetings. I tried to compile Predator Kernel myself today, and failed: https://github.com/stormbreaker-project/kernel_xiaomi_lavender_4.19

Could you please point me to some direction about how to compile this kernel myself?
I did compile Raspberry Pi kernel but it was using GCC. Android require LLVM, I know nothing about it.

I'd like to try YEAH TCP congestion controller, because I feel(not sure) BBR need a long "slow start" period, and would keep the probed speed for some time. This is not true for mobile, radio link always keep changing and would be easily interfered.

I'm currently switching to Westwood+ as it is included in Predator Kernel.

I would like to try CAKE qdisc as it support Automatic capacity estimation, and get some congestion controller other than BBR. Both of these require recompiling kernel.

What are the differences between HMP and EAS version? And which one is better for performance?
Can they be installed on custom aosp roms?

Im not quite sure about the differences but forma performace go for EAS, as long you want long term performace with a good battery life
And yes you can do that with almost all custom kernels and roms

    Important Notes

    OLDCAM Variant=> For Custom Roms which are using Old Vendor Blobs!(Most Common as 95% roms are still using old blobs. If after flashing OLDCAM, camera don't work , then flash NEWCAM Variant! Camera will work surely! 100% Tested!

    NEWCAM Variant=> For custom roms and For MIUI Pie which are using latest vendor blobs!(Currently ,very less amount of Roms are using latest blobs. Some Examples are LOS Official, Xperience Rom etc.) If after flashing NEWCAM, camera doesn't work, then flash OLDCAM variant.Camera will work 100% . Flash this version on MIUI Pie.
