?

::dcmds

List available functions.

!command

!command

Escape to the shell and execute command.

base

=

In mdb, the = format character can be used to convert the left-hand expression value to any of the known formats. Formats for octal, decimal, and hexadecimal are provided.

callout

::callout

Print the callout table.

class

::class

Print scheduling classes.

cpu

::cpuinfo

Print information about the threads dispatched on the system CPUs. If the contents of a particular CPU structure are needed, the user should apply the $<cpu macro to the CPU address in mdb.

help

::help

Print a description of the named dcmd, or general help information.

kfp

::regs

The mdb ::regs dcmd displays the complete kernel register set, including the current stack frame pointer. The $C dcmd can be used to display a stack backtrace including frame pointers.

kmalog

::kmalog

Display events in kernel memory allocator transaction log.

kmastat

::kmastat

Print kernel memory allocator transaction log.

kmausers

::kmausers

Print information about the medium and large users of the kernel memory allocator that have current memory allocations.

mount

::fsinfo

Print information about mounted file systems.

nm

::nm

Print symbol type and value information.

od

::dump

Print a formatted memory dump of a given region. In mdb, ::dump displays a mixed ASCII and hexadecimal display of the region.

proc

::ps

Print a table of the active processes.

quit

::quit

Quit the debugger.

rd

::dump

Print a formatted memory dump of a given region. In mdb, ::dump displays a mixed ASCII and hexadecimal display of the region.

redirect

::log

In mdb, output for input and output can be globally redirected to a log file using ::log.

search

::kgrep

In mdb, the ::kgrep dcmd can be used to search the kernel's address space for a particular value. The pattern match built-in dcmds can also be used to search the physical, virtual, or object files address spaces for patterns.

stack

::stack

The current stack trace can be obtained using ::stack. The stack trace of a particular kernel thread can be determined using the ::findstack dcmd. A memory dump of the current stack can be obtained using the / or ::dump dcmds and the current stack pointer. The $<stackregs macro can be applied to a stack pointer to obtain the per-frame saved register values.

status

::status

Display status information about the system or dump being examined by the debugger.

stream

::stream

The mdb ::stream dcmd can be used to format and display the structure of a particular kernel STREAM. If the list of active STREAM structures is needed, the user should execute ::walk stream_head_cache in mdb and pipe the resulting addresses to an appropriate formatting dcmd or macro.

strstat

::kmastat

The ::kmastat dcmd displays a superset of the information reported by the strstat function.

trace

::stack

The current stack trace can be obtained using ::stack. The stack trace of a particular kernel thread can be determined using the ::findstack dcmd. A memory dump of the current stack can be obtained using the / or ::dump dcmds and the current stack pointer. The $<stackregs macro can be applied to a stack pointer to obtain the per-frame saved register values.

var

$<v

Print the tunable system parameters in the global var structure.

vfs

::fsinfo

Print information about mounted file systems.

vtop

::vtop

Print the physical address translation of the given virtual address.
