multiprocessor support: - Implement MP-safe halt. - Make the FPU saving code more like Bill's on the i386 MP branch. XXX This code will no doubt be revisited again. - Pass the cpu_info and trapframe to IPI handlers, saving some work in the handlers themselves, and also making it possible for the "pause" handler to reference register state for DDB. - Add "machine cpu" to DDB, making it possible to reference other CPUs registers (and thus get e.g. a traceback) from whichever CPU is actually running the debugger. - Garbage-collect "machine halt" and "machine reboot" DDB commands. They don't have a prayer of working properly in multiprocessor kernels, and didn't really work all that well in uniprocessor kernels. |
