The patches fix a panic/black screen regression on GCN 1 GPUs (SI, KV) caused by incomplete backporting of DC display configuration changes. The upstream commit that was backported (7009e3af0474) expected `pm_display_cfg` to be populated by the legacy DPM code, but the commits that actually populate it were never backported, leading to the crash. The patches are faithful reproductions of the upstream code and are appropriate for stable. I have one observation about a latent bug that exists in the upstream code itself (not introduced by this backport). **Verdict: Looks correct for stable backport purposes. One pre-existing upstream issue noted below.** --- Generated by Claude Code Patch Reviewer
