Subject: Re: [PATCH v7 0/3] x86/tdx: Fix HLT logic execution for TDX VMs
Date: Mon, 24 Mar 2025 18:53:53 +0000 [thread overview]
Message-ID: <20250324185353.1974105-1-afranji@google.com> (raw)
In-Reply-To: <20250228014416.3925664-1-vannapurve@google.com>
Tested with the specjbb2015 benchmark. It has heavy lock contention which leads
to many halt calls. TDX VMs suffered a poor score before this patchset.
Verified the major performance improvement with this patchset applied.
