Subject: [PATCH v6 10/14] arch/x86: Introduce new config parameter AMD_QOS
Date: Tue, 6 Nov 2018 15:41:19 +0000 [thread overview]
Message-ID: <20181106154034.15386-11-babu.moger@amd.com> (raw)
In-Reply-To: <20181106154034.15386-1-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.
