Hi, Thomas, Babu, and James,
Can we use "resctrl" to replace "intel_rdt" and "rdt" in kernel? "resctrl" is a neutral name and has been used in user interface already. Hopefully "resctrl" can be acceptable by ARM, AMD, and Intel. We only use "intel_rdt", "amd_qos", or "arm mpam" for vendor specific code.
Can we move all of Intel RDT, AMD QoS, and ARM MPAM code into a generic place fs/resctrl where both ARM and X86 code can stay? Thanks.
