@t_murray playing Genshin on my p4xl and noticed it spends a ton of time (12%) in show_pid_map in the kernel. I tracked it down to Bionic: https://t.co/AkYKKUCCZW

Genshin has 10k+ maps and the stack entry comes last. Made a hack for it but pls fix Bionic: https://t.co/Tq40JvBCqq

@t_murray Genshin 1.3 on Android 11. show_pid_map is right near the top of perf top

fun fact, you need memory in order to free memory in linux ;_;

[Sultan Alsawaf @kerneltoast]

@baalajimaestro "what did it cost?"
"all of my memory"

[Sultan Alsawaf @kerneltoast]

option 1: complain to me that Simple LMK causes freezes (guaranteed effective strat)
option 2: find a way to make that dying process get the memory it needs ASAP so it can go die
option 3: complain to me that Simple LMK causes freezes enough for me to implement option 2

[Sultan Alsawaf @kerneltoast]

...in which case, the process you killed needs to have its memory allocation satisfied so it can make its way back to schedule() and process its SIGKILL. but you're low on memory, so there's no memory for that dying process to take! wat do??

[Sultan Alsawaf @kerneltoast]

@MSF_Jarvis At best it'll only fix the bug with 4.14, not slmk's overall performance ;_;

[Sultan Alsawaf @kerneltoast]

@MSF_Jarvis kill me

@msiUSA_Tech The NVME drive in the Prestige 15 I just bought is only using 2 out of 4 PCIe lanes, so the drive runs at half speed in this laptop. Any fix? More info: https://t.co/5PWMQOaozw

@franciscof_1990 @MSF_Jarvis Why revert when you can git push -f?

🔥New FK Kernel Manager 4.7 update!
I don't really do Saturday releases, but had so many nice changes I couldn't wait to get it out.
Since interaction is a bit lower today if you could like and retweet it helps me tremendously! Changelog blow!
