Subject: [pve-devel] [PATCH-SERIES kernel] backport fix for kvm performance regression with Intel Emerald Rapids
Date: Thu, 19 Dec 2024 15:29:43 +0100	[thread overview]
Message-ID: <20241219142947.1447728-1-f.ebner@proxmox.com> (raw)

Stumbled across this in the news [0].

Built, installed on a (CPU type 'host') VM and started a nested VM for
both 6.8 and 6.11 as a smoke test. Note I have an AMD TR 7960X, but
AFIACT, the patch affects a general code path not specific to Intel
CPUs.
