Subject: [PATCH v2 0/4] Power off HCI devices before rfkilling them
Date: Tue, 2 Jan 2024 19:19:16 +0100 [thread overview]
Message-ID: <20240102181946.57288-1-verdre@v0yd.nl> (raw)
In theory the firmware is supposed to power off the bluetooth card
when we use rfkill to block it. This doesn't work on a lot of laptops
though, leading to weird issues after turning off bluetooth, like the
connection timing out on the peripherals which were connected, and
bluetooth not connecting properly when the adapter is turned on again
quickly after rfkilling.
This series hooks into the rfkill driver from the bluetooth subsystem
to send a HCI_POWER_OFF command to the adapter before actually submitting
the rfkill to the firmware and killing the HCI connection.
