    Last of the per resource group files. Also mode 0644. This one shows
    the resources available to the group. Syntax depends on whether the
    "cdp" mount option was given. With code/data prioritization disabled
    it is simply a list of masks for each cache domain. Initial value
    allows access to all of the L3 cache on all domains. E.g. on a 2 socket
    Broadwell:
            L3:0=fffff;1=fffff
    With CDP enabled, separate masks for data and instructions are provided:
            L3DATA:0=fffff;1=fffff
            L3CODE:0=fffff;1=fffff
