Subject: [PATCH 11/13] xenpm: Factor out a non-fatal cpuid_parse variant
Date: Mon,  3 May 2021 15:28:08 -0400	[thread overview]
Message-ID: <20210503192810.36084-12-jandryuk@gmail.com> (raw)
In-Reply-To: <20210503192810.36084-1-jandryuk@gmail.com>

Allow cpuid_prase to be re-used without terminating xenpm.  HWP
will re-use it to optionally parse a cpuid.
