From ba58efa890cc8c9df8e072397ad153f04d06c24b Mon Sep 17 00:00:00 2001 From: John Smith Date: Tue, 21 Oct 2025 11:09:09 +0200 Subject: [PATCH] drm/amd/pm/powerplay/smumgr: Fix PCIeBootLinkLevel value on Iceland [ Upstream commit 501672e3c1576aa9a8364144213c77b98a31a42c ] Previously this was initialized with zero which represented PCIe Gen 1.0 instead of using the maximum value from the speed table which is the behaviour of all other smumgr implementations. Fixes: 18aafc59b106 ("drm/amd/powerplay: implement fw related smu interface for iceland.")
