The series introduces new HSMP messages for enhanced system management and implements variable-sized metrics table support. Patch 1 adds New HSMP message definitions for Family 1Ah Model 50h-5Fh processors, extending the HSMP interface capabilities. The driver version is bumped to 2.6 to reflect these additions. Patch 2 implements support for variable-sized metrics tables introduced in these new processors. Enhance hsmp_metric_tbl_read() with offset support. The series maintains backward compatibility with existing HSMP implementations while enabling new functionality for the latest AMD processors.
