Bug description:
[ Impact ]
Currently, the built-in NVM is loaded because Qualcomm hasn't released
correct NVM files until recently. This results in poor bluetooth
performance.
Firmware finally landed in upstream linux-firmware:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=77a11ffc5a0aaaadc870793d02f6c6781ee9f598
Required kernel patch:
https://lore.kernel.org/all/[email protected]/
[ Test Plan ]
Boot and check that the new firmware is loaded and that bluetooth connections
can be established.
dmesg:
[ 6.159831] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv
[ Where Problems Could Occur ]
Kernel patch specific to QCA bluetooth driver. New firmware that is
only loaded on specific Qualcomm HW. Should not affect any other
users.
