Subject: [PATCH v3 08/15] perf tool: Sync include/uapi/linux/perf_event.h header
Date: Wed, 28 Sep 2022 15:27:58 +0530	[thread overview]
Message-ID: <20220928095805.596-9-ravi.bangoria@amd.com> (raw)
In-Reply-To: <20220928095805.596-1-ravi.bangoria@amd.com>

Two new fields for mem_lvl_num has been introduced: PERF_MEM_LVLNUM_IO
and PERF_MEM_LVLNUM_EXTN_MEM which are required to support perf mem/c2c
on AMD platform.
