Note: This libpfm4 update was tested on the r8i.large AWS instance whcih has an Intel Xeon 6975P-C CPU (Granite Rapids). The PAPI utilities function properly and the changes in the feature branch indeed update the available native events. Futher sanity testing was done on an Intel Sapphire Rapids (Inel Xeon 6430) and again the PAPI utilities functioned properly.
