Support for schemata field in Intel RDT configuration #1746
Description
The OCI runtime specification recently merged a change (see opencontainers/runtime-spec#1230) to add a new schemata field to the Linux IntelRdt configuration (config-linux.md).
This field allows for specifying the complete schemata to be written to the schemata file in the Linux resctrl filesystem. This is intended to simplify runtime implementation and support current and future RDT features (like L2 cache allocation, CDP, L2CODE, L2DATA, L3CODE, L3DATA, etc.).
crun should be updated to support this new schemata field.
The behavior of existing RDT fields (l3CacheSchema, memBwSchema) is not changed by the spec, but the new schemata field should be applied last if present.
