Power Saving Settings

[sloo...@gmail.com]

I have an ESOS server that doesn't need to have high performance, power savings is much more important. I can set it manually with "echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" which does save power but of course this does not persist across reboots. Is there anyway to set the power saving settings in the startup config? Perhaps using "x86_energy_perf_policy power" or some other setting?

[Marc Smith]

I'd put the custom adjustments in "/etc/rc.local" and ensure it's
executable ('chmod +x /etc/rc.local').

Thanks Marc. The only issue left is that I see that C2 states have been disabled. Where do the below settings get set on boot? I see in the boot log that it sets it to maximum performance and disables C2 states.

Sat Jul  9 11:55:06 2022: Disabling the C2 CPU idle state...

Sorry, I missed this one... you could modify the ESOS source for this
rc/init script and change it there, or if you're on a recent version
that uses squashfs images (instead of cpio), you could unsquashfs it,
modify the image, then put it back together and replace it in the
"/mnt/root" file system.

Thanks Marc I'll give it a try.

That worked great! Another question for you. From what I can tell the Qlogic QLE2764 appears to be supported by the SCST 32Gb driver, but even after compiling 4.0.11 from source with the ./configure --enable-qla32 ESOS still doesn't load any driver. Is this card not supported? I found this is DMESG:

Nothing that I know off of the top of my head... is it an OEM HBA (like HP branded)? Or retail QLogic? Perhaps try another HBA and see if that works... otherwise you could dig through the driver source and try to understand what those messages mean.

Thanks for response Marc. I ended up with two defective QLogic branded cards from eBay before finally getting a 3rd that works just fine. I have never seen anything quite like it. The mobo detected it and you could even update the firmware on them, but Linux would give the above error. Windows detected them fine, but I could never get a link. Thanks again!

Glad this worked out, thanks for sharing the resolution.
