Subject: [PATCH v4 1/7] perf: Add EVENT_ATTR_ID to simplify event attributes
Date: Wed, 9 Jun 2021 14:40:57 +0800 [thread overview]
Message-ID: <1623220863-58233-2-git-send-email-liuqi115@huawei.com> (raw)
In-Reply-To: <1623220863-58233-1-git-send-email-liuqi115@huawei.com>
Similar EVENT_ATTR macros are defined in many PMU drivers,
like Arm PMU driver, Arm SMMU PMU driver. So add a generic
macro to simplify code.
