From b5453a8ec310f3ee2f7689958d63d9b8ffcbcd3e Mon Sep 17 00:00:00 2001 From: James Morse <james.morse@arm.com> Date: Fri, 7 Jun 2019 16:14:08 +0100 Subject: [PATCH] Documentation: x86: Clarify MBA takes MB as referring to mba_sc "If the MBA is specified in MB then user can enter the max b/w in MB" is a tautology. How can the user know if the schemata takes a percentage or a MB/s value? This is referring to whether the software controller is interpreting the schemata's value. Make this clear.
