you may have a try to modify this file, $OUT/Linux_for_Tegra/bootloader/tegra234-mb1-bct-misc-common.dtsi
please update the ccplex_platform_features as 0x1 to enable hybrid mode;
i.e. ccplex_platform_features = <0x1 0x00000000> for all hybrid.
you’ll need to modify num_clusters_2core_pair_lockstep to enable lock mode, the value is the number of clusters present in the system.
i.e. ccplex_platform_features = <0x0 0x00000000> && num_clusters_2core_pair_lockstep = <0x3> for all lockstep.
Booting standard/default L4T in lock/hybrid mode is not supported.
Please disable the ‘C7’ cpuidle state by setting “min-residency-us” property to ‘0xFFFFFFFF’ in the below DT node to boot in lock/hybrid mode.
