#1

It appears that bug #857997 in Debian's tracker was merged into Bug #854695. Just wanted to note that, and update the external tracker URL.

UGH, apparently Launchpad like to link bugs for you, and in this case, it linked the Debian bug #s to unrelated projects/package bugs...Please disregard the links in Comment #1

I looked into this a bit more, and it seems Ubuntu is basing off of linux-firmware at kernel.org and not following Debian's use of firmware-misc-nonfree. I'm removing the watch related to firmware-misc-nonfree, but there appears to still be an issue with update-initramfs and the i915 firmware for Kabylake and Broxton systems.

Also hit this issue on a Dell XPS 13 9360 (i7-8550U) running 17.10 and initramfs-tools 0.125ubuntu12. Until a fix is available, I was able to workaround the issue by adding my own initramfs-tools hook.

I created a hook script to copy the firmware:

$ cat /etc/initramfs-tools/hooks/i915_add_kbl_guc_ver9_14
#!/bin/sh

PREREQ=""
prereqs()
{
echo "$PREREQ"
}

case $1 in
prereqs)
   prereqs
   exit 0
   ;;
esac

. /usr/share/initramfs-tools/hook-functions
# Begin real processing below this line

copy_file firmware /lib/firmware/i915/kbl_guc_ver9_14.bin /lib/firmware/i915/kbl_guc_ver9_14.bin
exit 0

Marked the script as executable, and updated all initramfs images:

$ sudo chmod u+x /etc/initramfs-tools/hooks/i915_add_kbl_guc_ver9_14
$ sudo update-initramfs -k all -u
$ sudo update-grub

After reboot, success:

$ sudo cat /sys/kernel/debug/dri/0/i915_guc_load_status

Thanks Paul, that workaround helped me. The 9.14 GuC loads now. I tried downloading the new 9.39 GuC on intel's site, and changing the version in the hook script, but the 9.39 firmware would not load for some reason. Maybe due to both firmware versions existing in /lib/firmware/i915/ on my system and the older one being seen/used first. I might try again later and moving the older firmware, but am content with it loading as it is now.

*********************

Looks like its more a kernel issue related to the Dell drivers, not requesting the missing GuC.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

I suppose initramfs is not faulty; maybe linux-firmware is.

Better opening a separate kernel bug on launchpad and upstream to get a fix chance (need to check the latest kernel version to know if that issue is solved)

i can just add that its working fine under arch. However the error occurs under ubuntu 18.04. Both use 4.15.

Moreover i have a thinkpad x1 gen 6 and not a dell

Good to know; so its mostly due to the ubuntu kernel patches added / custom settings.

This is the commit that is responsible for the Kabylake GuC firmware file not being registered in the i915 module on Ubuntu kernels: http://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/commit/drivers/gpu/drm/i915/intel_guc_fw.c?id=dc0f16f9b5084e6be2b8c79f8c6cd499a3451791

This is the accompanying bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1626740

I've also commented there to bring the issue to their attention. The change should be reverted now that the formerly missing firmware files are present in linux-firmware.

Are they aware the same issue appears to be happening with the Broxton firmware as well? Should that be tracked under a separate issue?

Reverting that commit will address the firmware loading issue for both kbl and bxt. Although as far as I understand, Intel had cancelled Broxton, and there are no chips based on it in the market, so it's basically Kaby Lake users that are affected.

I built a Bionic test kernel with a revert of the following commit:
dc0f16f9b508 ("UBUNTU: SAUCE: (no-up) i915: Remove MODULE_FIRMWARE statements for unreleased firmware")

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1728238

Can you test this kernel and see if it resolves this bug?

Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the linux-image-unsigned, linux-modules and linux-modules-extra .deb packages.

Thanks in advance!

@mtvoid Thank you for clearing that up. I was not aware that Broxton was Atom. For some reason I thought it was an earlier generation x64 Core architecture.

@jsalisbury I am running Bionic. I've never tested a kernel before, but am willing to do so.

And to clarify when I ran:

The first round of firmware files is for 4.15.0-21-generic while the second listing is for your patched kernel. Notice the added GuC entry. As you can see the GuC firmware loads when running your patched kernel.

Thank you for building the test kernel :)

It now appears reverting Bionic commit dc0f16f9b508 has introduced bug 1777242. We need to put now either revert the revert or find an alternative fix.

On the face of it, I cannot see how this particular commit could in any way cause that other bug to arise. All it does is to allow the i915 driver to load a particular firmware file, and that too only if it's explicitly specified on the kernel command line.

I think bug 1777242 needs to be investigated further, to find the exact conditions under which it can be reliably replicated. The comment https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777242/comments/8 (regarding an error with the qkl.ko module for QEMU), seems worth looking into.

Disclaimer : what I did concerns 4.15.0 kernel only, on Intel machine (Assus Zenbook pro, x86_64, model: UX410UAR)

Hello,

Sorry for coming late, but I had the same issue some days ago (never tested before):something like Guc not loading, while Huc did. Of course I hit this page, and some other without find a complete solution.

**But** after one day searching, I finaly make it work (!!) , and I'll try to explain what I did (I do not recommend to do the same, but I'll attach a patch (under MIT license, or whatever you need, just ask).

The problems:

1. when you download the kbl_guc_ver9_14.bin blob from Intel site, looks like the downloaded file is an .xml file in fact, but not a binary at all. Maybe the site has an issue ? (sorry, not a website specialist) // Can someone verify btw ?

2. IIRC Intel made kbl_guc_ver9_xy.bin for Kabylake, and I simply tried to make the kbl_guv_ver9_39.bin work.

Important: I found kbl_guv_ver9_39.bin blob there : http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/

What I did :

- I extracted kbl_guv_ver9_39.bin from linux-firmware_1.178_all.deb, and put it in /lib/firmware/i915

After that, I downloaded the most recent 4.15.0 kernel sources (on my LinuxMint 18.3) :

=> apt-get source linux-source-4.15.0 provided :

Réception de :1 http://ubuntu.mirrors.ovh.net/ftp.ubuntu.com/ubuntu xenial-updates/main linux-hwe 4.15.0-47.50~16.04.1 (dsc) [6 511 B]
Réception de :2 http://ubuntu.mirrors.ovh.net/ftp.ubuntu.com/ubuntu xenial-updates/main linux-hwe 4.15.0-47.50~16.04.1 (tar) [158 MB]

After I downloaded the sources, I copied initrd.img-4.15.0-34-generic as .config in the kernel tree, and I simply patched the following files (in drivers/gpu/drm/i915 :
- intel_guc_fw.c
- intel_uc.c

Comments :
- In the first one, I simply modified the binary version (changing KBL_FW_MINOR from 14 to 39)
- In the second one, I followed Robert M. Fosha advice (link : https://patchwork.kernel.org/patch/10877903/), allowing to avoind timeout and retry when trying to load the blob

=> see the attached patch.

For the record, my current /etc/modprobe.d/i915.conf contains :

````
options i915 enable_fbc=1 fastboot=1 enable_guc_loading=1 enable_guc_submission=1

````

Next step was to build the kernel, the Debian way (using make -j8 deb-pkg), and after installing the debs, I got everything working at the end, including the 9_34 version of kbl_guc blob :-) :
