[TRACKING] PPD v TLP for AMD Ryzen 7040

Framework Laptop 13 Linux
79

Additional Observations
I’ve been running both via TLP and PPD this week and have noted the following.

  • TLP doesn’t always apply settings from its config. For instance, usb autosuspend seems to be hit or miss. After checking systemctl status tlp and dmesg for clues, the cause is still inconclusive. There is an updated kernel (6.5.0-1008-oem), so I’ll test that.
  • PPD was the power management approach du jour. The first 10% use took 69 mins at 4.78W avg draw. 20% use took 126 mins for avg draw 5.24W. Started playing music at 68% which brought the avg draw up to 5.78W over 17% usage. Settings were PPD: power-saver + amdstate: active, EPP: power + usb autosuspend
  • based on a few times listening to music, I’ll be replacing pulseaudio with pipewire to eval efficiency (already in use on Fedora 39 & Ubuntu 22.10)
  • I started this testing with a simple question in mind: Can my FW13 last a day without mains? Yes it can.
