[Daniel van Vugt <2111684@xxxxxxxxxxxxxxxxxx>]

We need the fix in newer series' first:

1. Questing (create an MR to debian-unstable at https://salsa.debian.org/xorg-team/lib/libpciaccess/-/merge_requests unless Timo can progress the upstream MR)
2. Plucky
3. Optionally oracular but probably not since EOL is soon.
4. Noble

Bug description:
  [ Impact ]

   * On AMD platform with Nvidia dGPU, if the iGPU is not VGA compatible. and pci order is later than NV
   * The system will select Nvidia as the primary GPU, which is wrong on AMD platform.

  [ Test Plan ]

   * On AMD (StrixPoint or KrakanPoint) platform with Nvidia dGPU

   * Check the renderer by $ xrandr -display <display name>
  --listproviders

   * Provider 0 should be AMD graphic

  [ Where problems could occur ]

   * If Nvidia dGPU is VGA compatible and the boot_vga is set, the
  system still select Nvidia as the primary GPU.

   * If the platform AMD graphic card acpi companion is not configured
  in the BIOS, the system still select Nvidia as the primary GPU.
