Title:
Support Edge Gateway's Bluetooth LED
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
Status in linux source package in Cosmic:
Fix Released
Bug description:
== Impact ==
The Bluetooth LED of Marvell 88W8897 is not enabled by default (there's no
code for controlling LED). It is requested to be ON and OFF when the radio is
on and off accordingly.
== Fix ==
The LEDs are connected to GPIO pins on the Marvell WiFi/Bluetooth combo
module, thus they can only be controlled via firmware.
== Test Case ==
# hciconfig hci0 [on|off]
and see if the LEDs work properly.
== Risk of Regression ==
PCI sub IDs of the host bridge are used to determine if we're really running
on an Edge Gateway, and we already have these patches in Xenial kernels quite a
while. Risk should be reasonably low.
