[RESPONDED] Gnome Extension Battery Health Charging info /test for Framework laptop

Framework Laptop 13 Linux
#1

I am interested in adding Frameworks laptops ability to control battery charging limit to Gnome extension “Battery Health Charging” which provides a GUI in gnome-shell quick settings menu, that few might be interested.
From information that I have gathered, I found 2 tools to can be used to change charge limit.

  1. ectool - Dhowett found on Github (Damn cannot post more than two links)
  • Can be set by the command sudo ectool fwchargelimit 80
  • The first and most popular tool used for changing charching limit.
  • Also found mentioned ArchLinux website. (cannot post more than two links)
  • Default installation location when install from archlinux repository /usr/bin/fw-ectool
  1. framework_tool
  • Officially supported by Frameworks (cannot post more than two links but it is in the repo framework-system)
  • Can be set by command sudo framework_tool --charge-limit 80
  • Also found mentioned ArchLinux website (Again cannot post more than two links)
  • Default installation location when install from archlinux repository /usr/bin/framework_tool

I wasn’t sure which tool to go for as I do not know the benefits/drawback for each tool. (Feedback on this is appreciated) . Since framework_tool is officially supported, I have already build a drafted test version of extension around the framework_tool.
The only prerequisite is that framework_tool will have to be installed/copied at /usr/bin/ as the extension check if the file present. In other words extension will notify that device not supported if failed to find /usr/bin/framework_tool
Since I don’t have framework laptop, I cannot test and dont know if this will work.

Anyone interested in testing and providing feedback let me know. I am open to suggestions.

draft version is found here:
Gnone 42-44

Gnome 45

Just and FYI Currently neither of these work with the amd frameworks; David hasn’t updated his efi tool either to support the amd ec. There is an out of tree patchset which I am just testing, but it was knocked back from inclusion into mainline and needs to be resubmitted with some trivial adjustments.

Echoing this.

Do you know when the support for AMD laptop will be available?

Sometimes I just want to set the charge limit to 100% if I need to go out, is there any workaround for that?

ATM I just starred those two projects

Which seems to be the official ones

There is a patchset which I am using without issue, but it needs to get resubmitted for inclusion in mainline.

Likewise the userspace tools will need updating to support the AMD EC.

There is actually a sysfs EC expose knob which makes the EC available from standard kernel fs structures, but it’s disabled in most sane distro kernels.

Interesting, so there are 3 ways to set charging threshold. 2 tools and a kernel module.
Thats great. I think I will wait for the kernel module to be released or merge with mainline then.
