I'm not convinced GLAN config for boards is configured correctly (should we be using drivers/net
?), so I'll leave this open until the configs can be checked.
I don't know what is disabling power management in the kernel. May be the kernel itself with all the commits mentioning ASPM problems I see in drivers/net/ethernet/realtek
.
The system will not go to C-states lower than C3 when idle.
Steps to reproduce
sudo cat /sys/kernel/debug/pmc_core/package_cstate_show
Expected behavior
Actual behavior
Additional info
Power management for GLAN is disabled.
Setting automatic power management will allow deeper C-states.
