[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/2115860

[Impact]
The system with amdgpu can't poweroff.

[Fix]
This series of patches fix the issue
https://lore.kernel.org/amd-gfx/20251002174245.1691343-1-mario.limonciello@amd.com/

Included in 6.18
531df041f2a5 drm/amd: Avoid evicting resources at S5

Included in linux-next, should be included in 6.19
173360fe49c2 drm/amd: Pass IP suspend errors up to callers
b7ff2e79240a drm/amd: Don't always set IP block HW status to false
f35f2541780b drm/amd: Remove comment about handling errors in amdgpu_device_ip_suspend_phase1()
6062ede68097 drm/amd: Stop exporting amdgpu_device_ip_suspend() outside amdgpu_device
e6af507de859 drm/amd: Unify shutdown() callback behavior

[Test]
Try powering off AMD platforms which runs with amdgpu igpu or dgpu couple times.
It should always be powered off.

[Where problems could occur]
These patches address about the amdgpu shutdown or suspend process, I don't
see there is any potential issue.
