x86: x86 Platform Debugging Support (unix)

These dcmds and walkers are specific to x86 platforms.

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.

Walkers

ttrace

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