Subject: RE: [PATCH v5 08/12] x86/resctrl: Add sysfs interface to read mbm_local_bytes event configuration
Date: Tue, 27 Sep 2022 22:42:17 +0000 [thread overview]
Message-ID: <IA1PR11MB609736EB0036405567A851649B559@IA1PR11MB6097.namprd11.prod.outlook.com> (raw)

Hi, Babu,
> By default, the mbm_local_bytes configuration is set to 0x15 to count all the

> 0:0x15;1:0x15;2:0x15;3:0x15
Schemata has format: "id0=val0;id1=val1;...". Maybe it's better to use
similar format here: 0=0x15;1=0x15;2=0x15;3=0x15? So we can have uniform formats across
resctrl.
Thanks.
