6 Execution Control in MDB
MDB provides facilities for controlling and tracing the execution of
live running programs, including both user applications and the live operating
system kernel and device drivers. You can use the mdb
command
to control user processes that are already running, or create new processes
under the control of the debugger. You can boot or load kmdb
to
control the execution of the operating system kernel itself, or debug a device
driver. This chapter describes the built-in dcmds that can be used to control
target execution. These commands can be used in either mdb
or kmdb
, except as noted in the descriptions. Additional topics relating
only to execution control in kmdb
are discussed in Kernel Execution Control Using kmdb.
