I am surprised and somewhat confused as why no kernel for K20 Pro has KCal commits merged within? Is this because no one has brought them up for Android 10?

To be honest I don't use neither like KCAL so that's the real reason I never tried to implement this feature. Also many ROMs have KCAL behavior built in. Cheers.

Why do people constantly write on Telegram groups that this kernel is only good for power saving and not for gaming? I game with this kernel on RROS ROM and it's perfectly fine.

I'm on latest RR and I've been having these bluetooth related wakelocks: c8c000.qcom,qup_uart and hal_bluetooth_lock. I've searched it but i can't find a clear answer. I use a galaxy watch and I tried many different roms and kernels and I never had these wakelocks. What is this about? Is there any way to block these? And I deeply thank for this kernel, the best I tried for battery saving.

Hi guys,
For me, the better config for battery backup, Bliss Rom + Englezos Kernel.
I using V4A and works fine.
FOD is really fast.
Very very thanks developers!!!
