Subject: [PATCH v2 09/11] arch/x86: Introduce new config parameter AMD_QOS
Date: Fri, 5 Oct 2018 20:56:06 +0000 [thread overview]
Message-ID: <20181005205512.29545-10-babu.moger@amd.com> (raw)
In-Reply-To: <20181005205512.29545-1-babu.moger@amd.com>
Introduces the new config parameter AMD_QOS. This parameter will be
used to enable cache and memory bandwidth allocation and monitoring
features on AMD processors. This will enable common config parameter
PLATFORM_QOS if selected.
