The names of resources are used for the schema name presented to user-space. The name used is rooted in a structure provided by the architecture code because the names are different when CDP is enabled. x86 implements this by swapping between two sets of resource structures based on their alloc_enabled flag. The type of configuration in-use is encoded in the name (and cbm_idx_offset). Once the CDP behaviour is moved into the parts of resctrl that will move to /fs/, there will be two struct resctrl_schema for one struct rdt_resource. The schema describes the type of configuration being applied to the resource. The name of the schema should be generated by resctrl, base on the type of configuration. To do this struct resctrl_schema needs to store the type of configuration in use for a schema. Create an enum resctrl_conf_type describing the options, and add it to struct resctrl_schema. The underlying resources are still separate, as cbm_idx_offset is still in use. Temporarily label all the entries in rdt_resources_all[] and copy that value to struct resctrl_schema. Copying the value ensures there is no mismatch while the filesystem parts of resctrl are modified to use the schema. Once the resources are merged, the filesystem code can assign this value based on the schema being created.
