Stability issues and crashes #2

Closed gericho closed 3 months ago

gericho commented 3 months ago

Thank you for your cpu-perf! I have a problem with it BTW, I installed it on a ZTE MF286D with 23.05.2 but I had major stability issues and it crash continuously. Removing it did not remove the problem, so I had to set it to performance with the highest CPU frequency (715Mhz) on all 4 cores, the only way to make it stable.

I also tried to erase all, deleting the NAND and reinstalling from serial/tftp port the initramfs, and then the sysupgrade, but the issue remains.

Is it possible to reset to the default governor values, so will be safe to uninstall it?

Thank you!

Is it possible to reset to the default governor values, so will be safe to uninstall it?

Yes, sure. Disable (or remove) luci-app-cpu-perf and reboot your router. After rebooting, all CPU settings will return to default values.

gericho commented 3 months ago

The router crashed probably due to a kernel panic when I changed something, so are these parameters applied only temporarily, or are they stored in the kernel? Because I was able to wipe all and put back the iniramfs, but it is still giving kernel panic sometimes:

so are these parameters applied only temporarily, or are they stored in the kernel?

Of course it's temporary (until reboot). Kernel only stores the parameters it was compiled with. Performance settings are applied when the cpu-perf service starts. If service is disabled (does not start at system startup), then the performance parameters do not change. All service settings are stored in UCI (/etc/config/cpu-perf). Remove luci-app-cpu-perf and reboot the router.

Thank you very much for clarifying this point!
