x86: x86 Platform Debugging Support (`unix`)

These dcmds and walkers are specific to x86 platforms.

x86 Platform Dcmds

[ cpuid | address ] ::ttrace [-x]: Display trap trace records in reverse chronological order. The trap trace facility is available only in DEBUG kernels. If an explicit dot value is specified, this is interpreted as either a CPU ID number or a trap trace record address, depending on the precise value. If a CPU ID is specified, the output is restricted to the buffer from that CPU. If a record address is specified, only that record is formatted. If the -x option is specified, the complete raw record is displayed.

ttrace: Walk the list of trap trace record addresses in reverse chronological order. The trap trace facility is available only in DEBUG kernels.
