EmbeddedController VS clevis

git clone --depth 1 https://github.com/FrameworkComputer/EmbeddedController cd EmbeddedController make utils sudo ./build/bds/util/ectool #USE AT YOUR OWN RISK - YOU CAN BRICK YOUR LAPTOP

When I was getting ready to flash again, I noticed an issue about the compiler version used to build the firmware binary. I followed the advice, but more importantly I noticed that the issue has been recently fixed, and in the resolution, the maintainer says "Next release (hx20 3.19, hx30 3.07) will include them". It reminded me of something crucial: the Framework EC firmware source code repo doesn't have any particular indication of its level of stability at any given commit. Which commits could be considered fully tested releases? What if the head of the branch introduces a bug that they're working on fixing?

The EC code on the normal Framework devices is already based on the Chrome EC code anyway. https://github.com/FrameworkComputer/EmbeddedController

EC firmware is open sourced by framework: https://github.com/FrameworkComputer/EmbeddedController

There the keyboard input is handled by the embedded controller: https://github.com/FrameworkComputer/EmbeddedController/blob...

On the 16 the keyboard is a USB keyboard that could even be used standalone, without the laptop.

I tried the pre-compiled `ectool` from the TamtamHero's repository as we and comiled the EmeddedController from Framework (from this repository). Both give the same error message.

Great reminder that (as of right now) we're far removed from hardware that is 100% free (as in freedom). The closest we've got is probably provided by Raptor Computing Systems. However not everyone in the world is privileged enough to own such devices unfortunately. And I haven't dabbled into other possible mishaps that come with using such devices. The lack of "free-hardware" is a major concern though. I'd argue that there aren't enough reasons to be optimistic about this as of right now. Therefore our best bet is to not let good be the enemy of perfect; light at the end of the tunnel...

As far as I'm aware the only way to manually change the fan speed is using `ectool` from https://github.com/FrameworkComputer/EmbeddedController/

We open sourced our Embedded Controller (EC) firmware and made it available on GitHub for you to modify if you wish.

Recently learned that Clevis also supports Shamir Secret Sharing, and it's in fact the only way to configure multiple pins even if they're of the same type and authority (ie. the RAID0 of SSS):

Have a look at clevis and tang. These allow you do have one server - which could be your remote you want to pull from - to be source of the LUKS decryption on the system using tang.

Interesting question. I think so?

Looks like clevis is gpl3 - so I expect it's not packaged as standard for any of the bsds?

I haven't used it myself, but a solution with LUKS, TPM2, and clevis is the way I've seen other people set it up https://github.com/latchset/clevis

There are 3 ways to unlock a volume in a headless environment: - use a keyfile, located on an already available volume - use your device's TPM and utilize systemd-cryptenroll - use Clevis/Tang to unlock volumes remotely

I don't think there is a turnkey solution, but you can build what you are looking for with clevis, LUKS, and dm-crypt

We use clevis against multiple tang servers to provide Network Bound Disk Encryption (NBDE). It's possible to also use TPM2 but it's easier to use multiple tang servers (requiring more than one server to decrypt) in the datacenter.
