I am quite interested in WWAN support. My previous findings were reported
At the moment, using a branch based on a libreboot5, along with patch
#4056, it works quite well, but I do not have rfkill support (cf
any way to turn WWAN off.
Basically, there is no WWAN rfkill entry if you do "rfkill list"
Also, I noticed that while rfkill block 0 does turn off the wifi led,
rfkill block for bluetooth does not turn turn off its led (or even echo
'5-2' > /sys/bus/usb/drivers/usb/unbind)
My belief is some ACPI entries are missing to handle that.
I am going back into the ACPI table investigation, but I'm curious whether
anyone has had good results with WWAN, ie :
- if rfkill shows a WWAN entry
- if rfkill block reduces power consumption (cf
/proc/acpi/battery/BAT0/state) and turns off the LED.
I would also be interested to know if rfkill block bluetooth does turns off
the LED (the power consumption change might be too low to be noticeable)
