Unable to establish host communication about fw-fanctrl HOT 9 CLOSED

Apparently you have to disable secure boot in the bios to get I/O privilege

I didn't know that, I'll add it to the instructions

I am running into the same issue. I take it @jedfonner is also trying this on an AMD framework? :-)

Indeed I am!

I have the same issue, running Debian on an 12th Gen Intel framework

from fw-fanctrl.

Sorry guys, I'm running an intel 11th gen laptop, I can't troobleshoot this for you. fw-fanctrl is quite a simple script, could you guys dive into it and fix it for the newer framework hardware ?

from fw-fanctrl.

Okay, apparently this is because the version of ectool shipped with this repo is outdated, sorry
There's an ongoing PR with the latest version of the binary, it's not merged yet and there might be some refinements added soon but it should work okay-ish for AMD and okay for Intel : #21

from fw-fanctrl.

Should be fixed on main thanks to #21

I just got an AMD Framework 13 and would love to use this tool, but am getting similar errors as the OP. I'm on Ubuntu 22.04 with an AMD Ryzen™ 7 7840U.

There's also some sort of access issue since there's an additional "Error getting I/O privilege: Operation not permitted" message. And it still happens when I run ectool directly with root.
