Missing DG2 HUC firmware (i915)

[ABCMoNa]

[ Impact ]

Missing HUC firmware. For whatever it is required for, it won't work without the firmware.

[ Fix ]

Upstream linux-firmware commit 8f86b5ab3e051170ea240fc409d457e16e24bc21.

[ Test Case ]

$ cat /sys/kernel/debug/dri/1/gt/uc/huc_info

Should report HUC FW information.

[ Where Problems Could Occur ]

Limited to i915 DG2 (Arc2?) GPUs.

[ Original Description ]

$ sudo update-initramfs -k $(uname -r) -u
update-initramfs: Generating /boot/initrd.img-6.2.0-26-generic
W: Possible missing firmware /lib/firmware/i915/dg2_huc_gsc.bin for module i915
I: The initramfs will attempt to resume from /dev/dm-2
I: (/dev/mapper/vgubuntu-swap_1)
I: Set the RESUME variable to override this.
$

i915/dg2_huc_gsc.bin seems to be missing. While this is an experimental (?) Intel driver for Arc2 dedicated GPUs, and some of these products are no longer being sold, there will probably be people out there using it, and wishing to use the newer driver and HUC support.

Are there reasons not to include this firmware, or was it just an oversight, possibly following Debian's?

Thanks.

That firmware was released to kernel.org linux-firmwware after Jammy released, that's why it's missing in Jammy. We can SRU it into JAmmy but do you have the HW to test it?

[ABCMoNa (abcmona)]

I don't actually have a dedicated Intel GPU (and I think this firmware is specific to this?) to test it, sorry.

[Andre Ruiz (andre-ruiz)]

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1040012

[Timo Aaltonen (tjaalton)]

I actually do have DG2 (Arc something) and can test it with the hwe stack plus firmware. This should be enough to enable it on jammy, as lunar works fine.

[Timo Aaltonen (tjaalton)]

that said, huc is needed only (?) for media decode/encode, and I don't think we have support for that in jammy

[Jianshui Yu (jianshui)]

Hi Timo
I reproduce the issue on my laptap(intel iGPU + DG2) with ubuntu jammy after upgrade to kernel 6.2.0-26-generic and linux-firmware 20220329.git681281e4-0ubuntu3.17

$ uname -r
6.2.0-26-generic

$ sudo apt list --installed | grep linux-firmware

linux-firmware/jammy-updates,jammy-updates,now 20220329.git681281e4-0ubuntu3.17 all [installed]

if Huc missing, it will break media hardware decode/encode

I have a Lenovo ThinkPad T14 Gen2 (11th gen intel) with Iris gpu and I see this after upgrading to kernel 6.2.

00:02.0 VGA compatible controller: Intel Corporation TigerLake-LP GT2 [Iris Xe Graphics] (rev 01)

update-initramfs: Generating /boot/initrd.img-6.2.0-26-generic
W: Possible missing firmware /lib/firmware/i915/dg2_huc_gsc.bin for module i915

As pointed out above, this is a bug in the debian packaging (comment #4). Should be straightforward to fix.
 Why is the status "Incomplete"?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[BENDERLOQ (bender35)]

hello

Here another with the same problem, I have a GA-H61M-S2PV with an i5 of 2nd generation and give me the same error in each kernel update.

If it serves you, my PC has no dual start and has an Intel Graphics 2000 graphic, if I can help this error in the testing part, tell me.

I do not observe any operating anomaly programs or games (it works well)

[BENDERLOQ (bender35)]

Hello, here I leave a temporary solution, I have done it and it no longer shows me the error:

In normal mode, type this command in order to download the kernel.org file:

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915/dg2_huc_gsc.bin

now later with the root user, type the command cp in this way:

cp dg2_huc_gsc.bin /lib/firmware/i915/

log out of root and type the following command to update the initramfs with the new driver:

sudo update-initramfs -u

We type the password and the error will no longer appear.

reboot to secure driver installation

[Timo Aaltonen (tjaalton)]

it's included in lunar and up

[Jianshui Yu (jianshui)]

what will it be in jammy?
thanks

[Timo Aaltonen (tjaalton)]

Hello ABCMoNa, or anyone else affected,

Accepted linux-firmware into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/20220329.git681281e4-0ubuntu3.18 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Confirming that package linux-firmware 20220329.git681281e4-0ubuntu3.18 did fix the problem for me in Jammy.
