Subject: [PATCH v3 09/11] arch/x86: Introduce new config parameter AMD_QOS
Date: Thu, 11 Oct 2018 20:33:35 +0000	[thread overview]
Message-ID: <20181011203223.18157-10-babu.moger@amd.com> (raw)
In-Reply-To: <20181011203223.18157-1-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
RESCTRL if selected.
