W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915

These are firmware files which are referenced by the driver but as far as I can see not yet released publicly by Intel. The driver should fall back to using older firmware versions.

Closing as invalid. If you are seeing actual hardware support issues as a result of the missing firmware files please reopen this bug.

[Seth Forshee (sforshee)]

Reopening. This is generating enough confusion to warrant removing the offending MODULE_FIRMWARE statements from i915.

[John Donnelly (jpdonnelly)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-yakkety' to 'verification-done-yakkety'. If the problem still exists, change the tag 'verification-needed-yakkety' to 'verification-failed-yakkety'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Confirmed that the problem is fixed in 4.8.0-36.38.

[steve77 (funmaker-11)]

Apparently this isn't completely fixed yet as it is hit and miss If it works. Not all the newer kernels work.

[Seth Forshee (sforshee)]

@steve77, can you elaborate? Which release, what kernel version, and which files does it continue to complain about?

[mtvoid (mtvoid)]

/lib/firmware/i915/kbl_guc_ver9_14.bin and /lib/firmware/i915/bxt_guc_ver8_7.bin have been present in linux-firmware 1.165 onwards.

I believe the patch to remove the MODULE_FIRMWARE entries, http://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/patch/drivers/gpu/drm/i915/intel_guc_fw.c?id=dc0f16f9b5084e6be2b8c79f8c6cd499a3451791, should be reverted now, else many people on Kaby Lake hardware who try to load the GuC firmware will experience errors (https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1728238).

[Leszek (bigl-aff)]

Fully agree with above comment - I've KabyLake hardware and now cannot load GuC file on Ubuntu 18.04 with kernel from distribution (the same was with Ubuntu 16.04). Have to choose - use mainline kernel without many useful patches but with ability to load GuC or use distribution-provided kernel with all these patches but without ability to load GuC.

[Leszek (bigl-aff)]

GuC file for Kaby Lake is present in kernel github (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915 ) from February 2017. So it's highest time to remove temporary patch added to address unreleased GUC firmware.
