So why do we need this interface? Or, IOW, > how is this interface better? It can call code in 32-bit physical mode in addition to real mode. So It can be used to call EFI runtime service, especially call EFI 64 runtime service under 32-bit kernel or vice versa. The main purpose of kexec jump is for hibernation. But I think if the effort is small, why not support general 32-bit physical mode code call at same time. Best Regards, Huang Ying
