Okay, there are 2 formulae that requires this, specifically - (.Ltrampoline_gdt_end - trampoline_gdt) - (trampoline_boot_cpu_entry - trampoline_start) just 3 symbols to export (trampoline_start is already exported) and 2 numbers to compute somehow (either linker script exporting absolute symbols or computing using code). > > ~Andrew > Frediano
