| |
i was thinking it would be nice to have show_regs show the EIP and call traceback for all processors in an SMP configuration, not just the interrupted processor.
it's easy enough to replace kbd_pt_regs with an array of pointers to struct pt_regs, and print the contents during a sysreq. but how could i grab the stack frame on the other CPUs?
perhaps the keyboard interrupt could instead trigger an IPI to all processors in the configuration which causes them to dump their stack frame on the console.
comments? anyone already have a patch that does this?
