I have tried the FDT /chosen approach, storing the KHO metadata as linux,kho-fdt and linux,kho-scratch properties (the same properties that drivers/of/kexec.c:kho_add_chosen() writes and drivers/of/fdt.c:early_init_dt_check_kho() reads). This passes the KHO selftest when the system boots with FDT. I am currently debugging the ACPI boot case. Thanks for your advice! -- Regards, George Guo
