Subject: [PATCH v3 4/8] perf cs-etm: Refactor enumeration cs_etm_sample_type
Date: Tue, 11 Dec 2018 15:38:24 +0800	[thread overview]
Message-ID: <1544513908-16805-5-git-send-email-leo.yan@linaro.org> (raw)
In-Reply-To: <1544513908-16805-1-git-send-email-leo.yan@linaro.org>

The values in enumeration cs_etm_sample_type are defined with setting
bit N for each packet type, this is not suggested in the usual case.

This patch refactor cs_etm_sample_type by converting from bit shifting
values to continuous numbers.
