Subject: [PATCH v3 0/2] x86/amd_node: Fixes for virtualized systems
Date: Tue, 25 Aug 2026 17:48:01 -0400 [thread overview]
Message-ID: <20260825214805.39148-1-jason.andryuk@amd.com> (raw)
For v3, Add newline to warning. R-b Yazen.
For v2, swap the patch order.
On my test system, I see SMN accesses from:
amd_pmf_probe() - read
amd_pmc_probe() - read
acp_acp70_audio_probe() - write
