The intr subcommand prints a summary for entries in the interrupt handler table if no argument or a slot number is entered.
intr [ slot | symbol | Address]
If no argument is entered, the summary contains information for all entries. If a slot number is specified, only the selected entries are displayed. If an address argument is entered, detailed information is displayed for the specified interrupt handler.

The mst subcommand prints the current context (Machine State Save Area) or the specified one.
mst [slot] [[-a] symbol | Address]]
If a thread slot number is specified, the mst for the specified slot is displayed. If an effective address is entered, it is assumed to be the address of the mst and the data at that address is displayed. The -a flag can be used to ensure that the following argument is interpreted as an address. This is only required if the value following the -a flag could be interpreted as a slot number or an address.

The proc subcommand displays process table entries. The * argument displays a summary of all process table entries.
proc
If no argument is specified details for the current process are displayed. Detailed information for a specific process table entry can be displayed by specifying a slot number or the effective address of a process table entry.

The thread subcommand displays thread table entries.
The * argument displays a summary of all thread table entries. If no argument is specified, details for the current thread are displayed. Details for a specific thread table entry can be displayed by specifying a slot number or the effective address of a thread table entry. The -w flag option can be used to display a summary of all threads with the specified thread wtype.
The TID, PRI, CPUID, and CPU fields can either be displayed in decimal or hexadecimal. This can be set using the set subcommand using the hexadecimal_wanted option. The current thread is indicated by an asterisk (*).
