5.15 pc-kernel uc22 snap fails to load bluetooth Intel firmware file intel/ibt-17-16-1.sfi

[Paul Larson]

When testing the beta image for uc22 on an Intel NUC, I noticed that bluetooth was not working. This NUC has worked for bluetooth tests on uc18, 20, and even on jammy. However on uc22, we see this in dmesg:
[ 11.954649] Bluetooth: hci0: Minimum firmware build 1 week 10 2014
[ 11.962817] Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-17-16-1.sfi (-2)
[ 11.966951] Bluetooth: hci0: Failed to read MSFT supported features (-56)

Here's the full dmesg with grep -i blue:

On Jammy, for comparison, the firmware gets loaded and bluetoothctl can see nearby devices:
[ 5.650860] Bluetooth: hci0: Minimum firmware build 1 week 10 2014
[ 5.653214] Bluetooth: hci0: Found device firmware: intel/ibt-17-16-1.sfi
[ 7.059104] Bluetooth: hci0: Waiting for firmware download to complete
[ 7.059838] Bluetooth: hci0: Firmware loaded in 1373648 usecs
[ 7.059903] Bluetooth: hci0: Waiting for device to boot
[ 7.073886] Bluetooth: hci0: Device booted in 13691 usecs

drivers/bluetooth/btintel.c only declares

MODULE_AUTHOR("Marcel Holtmann <email address hidden>");
MODULE_DESCRIPTION("Bluetooth support for Intel devices ver " VERSION);
MODULE_VERSION(VERSION);
MODULE_LICENSE("GPL");
MODULE_FIRMWARE("intel/ibt-11-5.sfi");
MODULE_FIRMWARE("intel/ibt-11-5.ddc");
MODULE_FIRMWARE("intel/ibt-12-16.sfi");
MODULE_FIRMWARE("intel/ibt-12-16.ddc");

thus during snap build we strip it, and it doesn't get included in the snap.

i wonder if we should adjust the MODULE_FIRMWARE to mention more things, or mentioned them with regexp. Such that we don't strip it and include them.

Separately will work on submitting that to our kernels.

Separately will work on trying to workaround this bug in our trim-firmware scripts for kernel snaps.

Can affected users please try kernel from https://launchpad.net/~xnox/+snap/xnox-pc-kernel/+build/1757817 ? and see if that helps to resolve the issue for them? Static analysis shows that all intel/ibt-* firmware files are now included.

I confirmed today that r1000 in beta fixes this. Thanks!

Solved downloading .sfi file for my network adapter and put in /usr/lib/firmware/intel. https://raw.githubusercontent.com/pop-os/linux-firmware/master/intel/ibt-19-0-0.sfi
