From d1b22e36e3188f47dbf8aaef54d9e79df8e91f4c Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Wed, 14 Oct 2020 00:49:26 +0000 Subject: Documentation/x86: Rename resctrl_ui.rst and add two errata to the file Intel Memory Bandwidth Monitoring (MBM) counters may report system memory bandwidth incorrectly on some Intel processors. This is reported in documented in erratum SKX99, erratum BDF102 and in the RDT reference manual, see Documentation/x86/index.rst. To work around the errata, MBM total and local readings are corrected using a correction factor table. Since the correction factor table is not publicly documented anywhere, document the table and the errata in Documentation/x86/resctrl.rst for future reference.
