Apparently some of these features > are defaulted to off by the firmware on the box I'm using, but we're not > sure why. I haven't dug into it. resctrl does not provide capability to override features that the hardware does not advertise as supporting. resctrl does sometimes force hardware advertised features off because of errata (for example, see [1]) and the kernel "rdt=" parameter can be used to override that. This same option also enables administrators to ignore some features on their platforms.
