Getting 'possible missing firmware error messages' after kernel related updates

  • 772

In Ubuntu 16.10 I am getting the following error messages when I do kernel related updates:

W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915

Everything seems to work on my Lenovo Yoga 3 Pro, but it would be good to know what this means and if I need to worry about it.

  1. It's not a bug...

    These are Intel drivers for future Integrated Graphics Processors (GPUs) that are not yet released to the public and are still in development. For example GuC v9.14 is for Kabylake and GuC v8.7 is for Broxton.

    On my system for example I see:

    update-initramfs: Generating /boot/initrd.img-4.8.1-040801-generic
W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1_01.bin for module i915
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915
W: Possible missing firmware /lib/firmware/i915/skl_guc_ver6_1.bin for module i915

    Even when the GPU is released and the binary files are released it still won't make a difference to your platform because it won't have the new GPU anyway.

    This question has been asked a few times in AskUbuntu and there are various bug reports floating around the internet but they all answers say it's not a cause for concern.
