** Description changed:

  SRU Justification:
  
  [Impact]
  On HP AMDGPU platform running the 6.14.0-1005-oem kernel, the monitor screen 
never appeared when booting the system with a Thunderbolt cable connected. 
However, we were still able to SSH into the system, suggesting that it had 
booted successfully.
  
  [Fix]
  Updates are required for both the Linux AMDGPU driver and the linux-firmware 
package.
  
  - Linux AMDGPU driver: cherry-pick the following commit from the Linux
  mainline:
  
  59510792baa drm/amd/display: Assign preferred stream encoder instance to
  dpia
  
  - linux-firmware: cherry-pick the following commits from the upstream
  linux-firmware repository:
  
  1. b3049665a5d amdgpu: DMCUB updates for various AMDGPU ASICs
  2. 61d257d5a8b amdgpu: DMCUB updates for various ASICs
  3. 5602c7293e6 amdgpu: DMCUB updates for various ASICs
  4. b0e96674082 amdgpu: DMCUB updates for various ASICs
  5. a80a8bd73e0 amdgpu: update dcn 3.5 and dcn 3.5.1 firmware to 9.0.27.0
  6. 25750add9b7 amdgpu: DMCUB updates for various ASICs
  
+ Be aware that only amdgpu/dcn_3_5_1_dmcub.bin is updated by the above commits.
+ Updates to other files were intentionally omitted.
+ 
  [Test Plan]
- 1. Connect the machine to an external monitor using a Thunderbolt cable 
before booting. 
+ 1. Connect the machine to an external monitor using a Thunderbolt cable 
before booting.
  2. Boot the system using the Noble OEM 6.14 kernel
  3. Verify that the display output appears on the monitor and the GNOME 
desktop environment is visible.
  
  [Where problems could occur]
  We updated the firmware to the latest version, while the Linux AMDGPU driver 
remains behind the mainline. As a consequence, a mismatch might occur between 
the Linux AMDGPU driver and the firmware.
