@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: cs.android.com/android/platfo… Genshin has 10k+ maps and the stack entry comes last. Made a hack for it but pls fix Bionic: github.com/kerneltoast/an…

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

...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??

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

@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: reddit.com/r/MSILaptops/c…

🔥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! Update: play.google.com/store/apps/det…
