Humm, not that I know of. And considering we are talking about PC hardware here (are we?), I can't imagine how it can be possible.
I'm definately no expert here, but PC hardware has many hardware level debuging hooks that apps such as oprofile take advantage of.
Sure does, but how does one recover from a hardware lockup ?
Well say the PCI buses timing gets hosed and the whole system seizes up what do you intened to do at that point (that is a hardware lockup)? And what does that thing you do have to do with debuging a kernel? Just curious.
Even if it were possible to have that kind of debugging, it would be fairly limited.
When you say "hardware" I start thinking jtag interfaces, or even more interesting was this thing we would place every pin of the processor through and then connect to the socket on the motherboard, but I think I missing something.
Cheers...james
