Subject: [PATCH v8 03/13] x86/msr-index: define AMD heterogeneous CPU related MSR
Date: Tue, 18 Feb 2025 13:08:12 -0600 [thread overview]
Message-ID: <20250218190822.1039982-4-superm1@kernel.org> (raw)
In-Reply-To: <20250218190822.1039982-1-superm1@kernel.org>
From: Perry Yuan <perry.yuan@amd.com>
Introduces new MSR registers for AMD hardware feedback support.
These registers enable the system to provide workload classification
and configuration capabilities.
