[TGL] graphics kernel support

[quanxian]

Description:

This feature tracks the updates TGL graphics updates.

We will submit the commit id lists since 5.4.

20.04 will use v5.4 as a base, (2109/11/25)

first commit lists will be provided in 2020/01, if you need more before that, please let us know.

Target Release: 20.10
Target Kernel: v5.8

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1855399

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[quanxian (quanxian-wang)]

This is the draft for this. not promise to include all tgl commits, Just take it as a reference.

[Timo Aaltonen (tjaalton)]

that list is for mesa, not kernel

[Timo Aaltonen (tjaalton)]

I've filed a separate bug for the oem kernel to track the first batch of fixes

https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.4/+bug/1868727

it should be for oem-5.6, but it's not in focal yet but maybe later this week.

[Timo Aaltonen (tjaalton)]

Thanks! There are a few that are missing from my patchset, I'll add them in the next batch.

[quanxian (quanxian-wang)]

hi, Timo

have you integrated into 20.04? if so, we can think Ubuntu 20.04 support TGL graphics. Not sure if you integrated into 20.04 or 20.04-oem?

[quanxian (quanxian-wang)]

from our testing of beta release, seems TGL graphics is not supported in Ubuntu 20.04 Beta release.

[Timo Aaltonen (tjaalton)]

correct, it's only for the oem kernel

There are duplicates in that list, and I've dropped some that need further work

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!
