Subject: [PATCH] process: Add profile logging for main loop
Date: Fri, 9 Feb 2024 23:56:15 +0000 [thread overview]
Message-ID: <20240209235615.3473502-1-richard.purdie@linuxfoundation.org> (raw)
When the idle/main loop was added, we didn't include profiling information
for it. There is a performance issue in there, add logging for it.
