Add the efi=runtime kernel command line option for all lowlatency UEFI installs so that the efibootmgr has access to EFI non-volatile variables. LAT will run the efibootmgr as one of that last steps of the ISO/pxeboot install to change the device boot order of the host. When the PREEMPT_RT kernel is enable this is required otherwise we will rely on the existing boot order of the system, often resulting in a pxeboot loop. As reference here is the difference in the std and rt kernel requiring this change: $ diff linux-yocto-{std,rt}/drivers/firmware/efi/efi.c 69c69 < static bool disable_runtime; --- > static bool disable_runtime = IS_ENABLED(CONFIG_PREEMPT_RT); 98a99,101 > > if (parse_option_str(str, "runtime")) > disable_runtime = false; Test Plan: PASS - Added parameter on a UEFI RT worker install in a H/W lab and observe that the previously failing post install reboot now boots successfully.
