Subject: [PATCH v2 04/13] x86/msr-index: define AMD heterogeneous CPU related MSR
Date: Thu, 10 Oct 2024 14:36:56 -0500 [thread overview]
Message-ID: <20241010193705.10362-5-mario.limonciello@amd.com> (raw)
In-Reply-To: <20241010193705.10362-1-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.
