Hello, thanks for your contribution. Is there any chance to have the option to disable efficient or performance cores in the next firmware, for example on NovaCustom NV41 laptop? I also saw another way to disable efficient or performance cores without needing to reboot, using taskset but I did not try it yet: https://unix.stackexchange.com/questions/686459/disable-intel-alder-lake-efficiency-cores-on-linux The option in the BIOS could still be useful to have a default configuration.
