Subject: [PATCH v7 03/12] x86/msr-index: define AMD heterogeneous CPU related MSR
Date: Sat, 30 Nov 2024 08:06:54 -0600	[thread overview]
Message-ID: <20241130140703.557-4-mario.limonciello@amd.com> (raw)
In-Reply-To: <20241130140703.557-1-mario.limonciello@amd.com>

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.
