Subject: [PATCH v2 01/27] tools headers uapi: Update tools's copy of linux/perf_event.h
Date: Thu, 11 Mar 2021 15:07:16 +0800	[thread overview]
Message-ID: <20210311070742.9318-2-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210311070742.9318-1-yao.jin@linux.intel.com>

To get the changes in:

Liang Kan's patch
("perf: Introduce PERF_TYPE_HARDWARE_PMU and PERF_TYPE_HW_CACHE_PMU")

Kan's patch is in review at the moment, but the following perf tool
patches need this interface for hybrid support.

This patch can be removed after Kan's patch is upstreamed.
