NV reverse prime HDMI has no output

An upload of mesa to jammy-proposed has been rejected from the upload queue for the following reason: "Looks like there's unintentional changes in src/mesa/formats.csv".

Is there a particular reason why we should take the PCI-ID removals? They seem safe enough, though.

Hello Kai-Chuan, or anyone else affected,

I ran update-maintainer on the mesa source and uploaded again.

Give the removal of PCI IDs, and the vague statement in the "Where things could go wrong" section of the bug description, I'd like to see a more clear statement saying that these IDs are already not available in the jammy kernel, and as such there is an even lesser risk of regression due to that.

the pci-id's were dropped from the jammy kernel for lp1990242

I think this bug/SRU snowballed. Let's take a step back.

It started with fixing two bugs: this one, and bug #1972977. At some point later, #1972977 was deemed not really fixed[1], and was dropped in the 0ubuntu0.3 upload[2].

That upload failed to build in jammy-proposed on arm64[3] and amd64[4].

It was deemed to be a problem introduced by some other jammy-proposed upload (unclear which one).

A new upload was made to jammy unapproved[5] (still missing an update-maintainer run, btw), stating:

Changes:
 mesa (22.0.5-0ubuntu0.4) jammy; urgency=medium
 .
   * Add a patch to build with a newer directx-headers. (LP: #1998893)
 .
 mesa (22.0.5-0ubuntu0.3) jammy; urgency=medium
 .
   * crocus-fix-leak-in-query-code.patch: Drop the patch so the other fix
     can get through to updates.
 .
 mesa (22.0.5-0ubuntu0.2) jammy; urgency=medium
 .
   * crocus-fix-leak-in-query-code.patch: Fix gnome-shell crashing on
     older Intel hw. (LP: #1972977)
   * patches: Update pci-id's for ADL-S/RPL-S. (LP: #1998893)

That is quite a big patch in an area I know nothing about. My concerns are:
- shouldn't we have a separate bug for the FTBFS? This bug here is about PCI IDs.
- what is the other package in jammy proposed that is breaking this build? Must it be released at the same time as mesa?
- the original PR[6] mentioned in the DEP3 header of the FTBFS patch is huge and complex, is that (and the backport done here) really the minimal fix for the FTBFS?
- what are the other changes incurring via this patch, now the the build is fixed? What else is changing? What is the risk analysis of that change?

I feel there is a lot of missing information, but it could just be because I'm not familiar with mesa and the graphic/3d stack. So I prefer to leave this review for another SRU team member, but thought I should leave this comment here instead of just "disappearing" :)

andreas, directx-headers was dropped instead, and that upload rejected, so the current version in proposed builds and is ready for updates. sorry for the hassle, this was supposed to be the correct path to follow all along :)

This bug was fixed in the package mesa - 22.0.5-0ubuntu0.3
