Subject: sim: Only print the power state transition warning once
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21b66f45422bc449d4a8b86ab452d6b6ae5838bf;p=gem5.git

sim: Only print the power state transition warning once

A lot of objects seem to request no-op power transitions which
currently results in large amounts of warnings. These warnings are
benign and risk hiding more serious warnings. Make the warning a
warn_once to prevent console flooding.
