Fixing firmware errors for the Intel graphics driver

When I upgraded my Ubuntu kernel, I got these errors:

W: Possible missing firmware /lib/firmware/i915/kblXXXXXXXX

Looks like some firmware files are missing, so I decided to fix them.

Someone wrote a script for this problem, but unfortunately it didn’t work for me. Still, his work gave me a good lead, and I eventually got it sorted.

From the errors we know the missing files are:

Kaby Lake DMC Kaby Lake GUC Broxton GUC Broxton HUC SkyLake HUC

So go to Intel’s official website, grab them, and install.

SkyLake HUC https://01.org/zh/node/5098

Broxton HUC https://01.org/zh/node/5094

Broxton GUC https://01.org/zh/node/5090

Kaby Lake GUC https://01.org/zh/node/5093

Kaby Lake DMC https://01.org/zh/node/4211

Extract the package and install with

sudo ./install.sh

Done!
