Subject: [PATCH v1 07/11] perf c2c: Rename dimension from 'percent_hitm' to 'percent_costly_snoop'
Date: Wed, 27 Apr 2022 23:50:09 +0800	[thread overview]
Message-ID: <20220427155013.1833222-8-leo.yan@linaro.org> (raw)
In-Reply-To: <20220427155013.1833222-1-leo.yan@linaro.org>

Use more general naming for the main sort dimension, this can allow us
not to sort only on HITM snoop type, so it can be extended to support
other costly snooping operations.  So rename the dimension to the prefix
'percent_costly_".
