[TLP 1.7 Beta] Call for testers

[linrunner]

Hi @ALL,

as with every upcoming release, I'm excited to get your help with test coverage!

Test Objectives

1. General regression testing (check if everything still works for you)

   • When changing the power source AC <-> BAT, do the tunables change accordingly (compare output of tlp-stat)?
   • Can the charge thresholds be changed ?
   • Does tlp recalibrate work? - ThinkPads only

2. Battery Care

   • Check if newly supported hardware is able to set start and stop charge threshold:
     • Apple Silicon Macbooks (M*) with MacOS 13.0 (or later) firmware and Asahi Linux kernel 6.6 (or later) - important: the firmware restricts the possible values to 75/80 and 95/100.
     • MSI laptops with kernel 6.3 or later - important: the kernel driver msi_ec only accepts individual models and BIOS versions, for the unsupported ones tlp-stat -b displays Plugin: generic / Supported features: none available
   • ThinkPads with coreboot: does tlp-stat -b show complete battery readings? See https://linrunner.de/tlp/faq/battery.html#are-thinkpads-with-coreboot-supported

3. Adaptive Backlight Modulation on AMD Vega or newer GPUs with kernel 6.9 or later

   • Configure AMDGPU_ABM_LEVEL_ON_BAT=3 and check with tlp-stat -g if the setting applies on battery = /sys/class/drm/card1/card1-eDP-1/amdgpu/panel_power_savings = 3 - on my AMD ThinkPad, it saves 0.5W at medium display brightness with a slight (subjective) loss of brightness, it has no effect at full or minimum display brightness.

4. General features

   • Are error, warning, notice and success messages shown in color?
   • Check the new Fish shell command completion

5. Any other of the new features that you like, check out the changelog

6. Bugfixes

   • xhci_hcd was added to RUNTIME_PM_DRIVER_DENYLIST defaults - do USB devices work properly on battery?

Beta Packages - Arch, Debian/Ubuntu and Fedora
See the download page.

What do I need from the testers?
After installing please start the beta with

sudo tlp start

I'm expecting your unabbreviated outputs of

sudo tlp-stat

on battery and AC (via Gist please).

Bug Reports
If something does not work as expected → please open an issue.

I look forward to your feedback on the beta :-)

Let's test.

• BAT https://gist.github.com/Mylinde/61d92a3a5b16c3833c27db51a0818c7a
• AC https://gist.github.com/Mylinde/5dd937813cc1deb747560081806dd079

Battery Care: START_CHARGE_THRESH_BAT0 not working, is set to 75 and has worked in latest release.

@Mylinde thanks for testing and your outputs. Looks perfect to me.

Negative. Your memory must be betraying you. The kernel driver asus_wmi has always supported a stop threshold only.
