Subject: [PATCH v7 08/10] perf/x86/rapl: Remove the global variable rapl_msrs
Date: Fri, 15 Nov 2024 06:08:04 +0000	[thread overview]
Message-ID: <20241115060805.447565-9-Dhananjay.Ugwekar@amd.com> (raw)
In-Reply-To: <20241115060805.447565-1-Dhananjay.Ugwekar@amd.com>

Prepare for the addition of RAPL core energy counter support.

After making the rapl_model struct global, the rapl_msrs global
variable isn't needed, so remove it.
