Subject: [PATCH 0/2] x86/amd_node: Fixes for virtualized systems
Date: Thu, 6 Aug 2026 12:01:55 -0400 [thread overview]
Message-ID: <20260806160159.230453-1-jason.andryuk@amd.com> (raw)
On my test system, I see SMN accesses from:
amd_pmf_probe() - read
amd_pmc_probe() - read
acp_acp70_audio_probe() - write
Jason Andryuk (2):
x86/amd_node: Remove smn_exclusive
