edk2 VS firmware-open

Now I knew I could flash my Lemur Pro with the “normal” sys76 firmware, I dug into the, script to work out what it was doing. It appears to consist of two parts: building the coreboot firmware (coreboot.rom, which I believe is renamed later in the script to firmware.rom) and building the ec firmware (ec.rom) <<< the ec is the bit I built/flashed in isolation for the keyboard changes. From what I’ve read about coreboot, it initially turns the system on and then delivers a package which contains the rest of the instructions to get the system started. The package that sys76 delivers with coreboot appears to be EDKII.

This reminds me a lot of FW update a8dd6c2, since rolled back, which came out about 4 months ago and caused problems with darp8 (e.g. https://github.com/system76/firmware-open/issues/469, https://www.reddit.com/r/System76/comments/1692nd2/darter_pro_fails_to_resume_after_fw_a8dd6c2/, https://www.reddit.com/r/System76/comments/168oehz/new_coreboot_update/)

I suspect that my current settings are still "overkill", so I'm wondering if there's a nice way (in the absence of https://github.com/system76/firmware-open/pull/365 being merged!) to find out what the minimum speed is I can get away with without my laptop spontaneously combusting? :D

There is an issue about this: https://github.com/system76/firmware-open/issues/407 They closed it (because there was an update), but yeah it's definitely not fixed. You can subscribe to this issue to see what's going on, but do not get your hopes high - they will rarely, if ever, update the issue.

There isn't a way without flashing the firmware at least once, but there is this PR instead which exposes userspace fan controls, which might work with some of the fan control software in Linux.

What Framework can't offer is Coreboot with Management Engine Cleaner and other great specs. System76 just announced a new fully open source bios for their intel 10th - 13 th gen models: https://github.com/system76/firmware-open/blob/77abfadf24c9a0c45ae042cd71d3ce7be26c846e/FEATURES.md

Hi! I check the firmware-open repository from time to time and noticed that since the initial release a few potentially interesting things have been committed (e.g. Disable ME by default on everything but TGL-U or Support for NVIDIA Dynamic Boost ). Should I wait for the "official" update to show up in firmware-manager? These changes seem to have been released quite some time ago, but there is no trace of them in the GUI. I am inclined to build and flash it myself. I've flashed my ec in the past, but I don't want to set the versions of ec and firmware-open too far apart. What's the policy here? There is this warning here about "normal" users who should not do this themselves. Perhaps I am not normal :-/
