SPARC: sun4u Platform Debugging Support (unix)

These dcmds and walkers are specific to the SPARC sun4u platform.

sun4u Platform Dcmds

[ address ] ::softint

Display the soft interrupt vector structure at the specified address, or display all the active soft interrupt vectors. The pending count, PIL, argument, and handler function for each structure is displayed.

::ttctl

Display trap trace control records. The trap trace facility is available only in DEBUG kernels.

[ cpuid ] ::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 a CPU ID number, and the output is restricted to the buffer from that CPU. If the -x option is specified, the complete raw record is displayed.

[ address ] ::xc_mbox

Display the cross-call mailbox at the specified address, or format all the cross-call mailboxes that have pending requests.

::xctrace

Format and display cross-call trace records in reverse chronological order that are related to CPU cross-call activity. The cross-call trace facility is available only in DEBUG kernels.

sun4u Platform Walkers

softint

Iterate over the soft interrupt vector table entries.

ttrace

Iterate over the trap trace record addresses in reverse chronological order. The trap trace facility is only available in DEBUG kernels.

xc_mbox

Iterate over the mailboxes used for CPU handshake and cross-call (x-call) requests.
