Problem with CPU cstates and wifi controller

Installing and Using OpenWrt
1

Hey guys.

I got the latest OpenWRT working but it seems that the CPU always runs at max performance.
The same machine (with an AMD E1-6010 CPU) uses around 7-9 Watts at idle but on OpenWRT, it uses over 15W.

I've installed amd64-microcode and amdgpu-firmware and rebooted but no results.

Also, I can't get my PCI BCM43142 Wifi card to work, even though I've installed the drivers that should work (b43 and b43legacy, just to be sure).

Any ideas?

Connect over SSH and check which scaling governor it's using, it should be ondemand to scale down the CPU freq when idle.

ondemand
