Querying the L2 I-Cache/D-Cache Configuration of CPU Cores

Use the CMF command line tool to query the L2 I-cache/D-cache configuration of the corresponding CPU cores.

• If --reset, --i-mask, and --d-mask are not specified, the command operates in query mode. In this case, the CPU core sequence must be specified. For example, to query the configuration of CPU cores 80 to 119, run the following command:

  ./devcman -m l2-restrict --start_cpu 80 --end_cpu 119

• To query the configuration of a single CPU core, set both start_cpu and end_cpu to the target core ID. For example, run the following command to query the configuration of CPU core 1:

  ./devcman -m l2-restrict --start_cpu 1 --end_cpu 1
