[KERNEL][PORT] Sultan Kernel for Android 11 [February 3, 2021]

Sultan Kernel Q 25/05/19

• Reworked Simple LMK

instead of killing a bunch of lowprio processes that bring the amount of mem freed almost up to the MINFREE and then killing a higher prio process that's larger than MINFREE, slmk will now only kill the larger higher prio process

Can I install your P kernel over the sultan's one?

Can I install your P kernel over the sultan's one?

Yes, but with other kernels you may have to flash the stock kernel first.

If you guys couldn't tell already, I'll pretty much be updating this everytime Sultan pushes a new change to his GitHub

Already figured that out
But next time can you please mention what changes or modifications for people like us that can't read github?
Cheers ?

I'll try to but tbh when I'm pushing releases so frequently, just looking at what has changed on the GitHub branch is probably faster and easier for me. The commits there typically have good descriptions of what they're changing. This builds change is such:

kernel: Don't override do_set_cpus_allowed() for perf-critical tasks

do_set_cpus_allowed() is only invoked directly when there are no online CPUs available in a task's cpus_allowed to place that task on. It shouldn't be overridden

If my changelogs are little to brief just look at the branch for recently committed changes. Apologies as my time is mostly preoccupied with exams and maintaining my other kernels atm.

Do I need to reflash Magisk after flashing in EXKM?

Is there a difference with gcc 9.1? I saw other devs doing that as well but never really understand the reason.

Refer to here for more information. TLDR GCC 9.1 > GCC 8 in terms of compiling speeds and scheduler performance

I'm just double checking if this works on walleye as well

Current version seems to be a bit more sluggish opening apps?

Might be worth informing @Sultanxda about this one. He reverted some input boosting when launching new processes in order to save power on our current high min freqs setup.
