But why not have a simple buffer definition which doesn't need CPUID? Also, doing the CPUID thing would need extending the gdb remote protocol as explained here: https://lore.kernel.org/r/971d21b7-0309-439e-91b6-234f84da959d@xxxxxxxxxxx The simple buffer layout won't. So regardless of where hw is going, I think a simple buffer definition is always better. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
