'MSR_PKG_CST_CONFIG_CONTROL' encodes the deepest allowed package C-state limit, and turbostat decodes it. Before this patch: turbostat does not recognize value "3" on Ice Lake Xeon (ICX) and Sapphire Rapids Xeon (SPR), treats it as "unknown", and does not display any package C-states in the results table. After this patch: turbostat recognizes value 3 on ICX and SPR, treats it as "PC6", and correctly displays package C-states in the results table.
