** Summary changed:
- /sys/power/suspend_stats/total_hw_sleep not increased after suspend/resume on
AMD Krackan Point platforms
+ /sys/power/suspend_stats/total_hw_sleep not increased after suspend/resume on
AMD GPU of DCN 3.5
** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ /sys/power/suspend_stats/total_hw_sleep not increased after suspend/resume on
AMD GPU of DCN 3.5.
+ ```
+ Critical failures:
+ s3: 2 failures
+ ========================================
+ Expected /sys/power/suspend_stats/total_hw_sleep to increase from 154857603,
got 154857603. (x 1)
+ Expected /sys/power/suspend_stats/total_hw_sleep to increase from 694652545,
got 694652545. (x 1)
+ ```
+
+ [Fix]
+
+ Proposed fix in upstream commit 5602c7293e663b1316c2002c493037412f8f0de3
+ ("amdgpu: DMCUB updates for various ASICs").
+
+ [Test Case]
+
+ checkbox tests should pass with all deep suspends:
+ ```
+ $ checkbox-cli run com.canonical.certification::suspend-cycles-stress-test
+ ```
+
+ [Where problems could occur]
+
+ Opaque GPU firmware limited to amdgpu of RDNA 3.5 architecture. There
+ might be further stability issues that need additional fixes from
+ kernel, and we can only find out with more deployments later.
+
+ [Other Info]
+
+ The proposed fix is under upstream tag 20250311 and therefore in Plucky
+ version 20250317.git1d4c88ee-0ubuntu1. Nominate for Noble only.
