Subject: [PATCH 2/5] x86/perfc: conditionalize HVM and shadow counters
Date: Fri, 3 Dec 2021 13:04:21 +0100 [thread overview]
Message-ID: <ea513864-58c0-fb90-cee6-f668309fcc38@suse.com> (raw)
In-Reply-To: <57038a1c-671b-f0f9-1bf1-0ff9bae6e2dc@suse.com>
There's no point including them when the respective functionality isn't
enabled in the build. Note that this covers only larger groups; more
fine grained exclusion may want to be done later on.
