Linux archlinux 5.12.1-1-MANJARO-ARM #1 SMP PREEMPT Fri May 7 09:33:12 CDT 2021 aarch64 GNU/Linux

Systemd-oomd only gets kicked off when a certain condition is met. In this case I believe it’s when memory pressure is at 60%.

i cant find /proc/pressure

ls /proc/pressure
ls: impossibile accedere a ‘/proc/pressure’: File o directory non esistente

is that normal?

4

maybe this is related?

We did enable PSI in recent kernels in Testing and Unstable branch. So if that’s all it’s missing to work, then it’s on its way.

I do have one of the last kernel:

5.16.4-1-MANJARO-ARM-RPI

I’ve enabled the systemd-oomd.service - Userspace Out-Of-Memory (OOM) Killer.

But I still have:

─ ConditionPathExists=/proc/pressure/memory was not met

What should create this tree structure?
