I'd like to detect when the kernel stack changes and it seems to me that might be possible by looking at when the tss structure is accessed and the esp element is changed. Linux uses a command something like the following to update the esp in the tss during a task switch...
init_tss[smp_processor_id( )].esp0 = next->thread.esp0; Is it possible to detect when this happens in qemu? Maybe in the protected_interrupt helper function? Thanks, Nuri
