context

Description

This is an abstraction of a virtual address space. It handles virtual-address breakpoints and may have symbol tables attached to it. Note that there is no automatic correspondence to any hardware or operating-system context, although such a mapping may be set up by the user.

Interfaces Implemented

conf_object, log_object, breakpoint, breakpoint_trigger, breakpoint_query_v2, breakpoint_query

Notifiers

cell-change: Notifier that is triggered after the object's cell was changed.
object-delete: Notifier that is triggered just before Simics object is deleted.
queue-change: Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.

Commands for this class

info – print information about the object
off – switch off context object
on – switch on context object
reverse-until-activated – reverse until context becomes active
reverse-until-deactivated – reverse until context becomes inactive
run-until-activated – run until context becomes active
run-until-deactivated – run until context becomes inactive
status – print status of the object

Commands for interface breakpoint

bp-break-memory – set break on memory access
bp-run-until-memory – run until specified memory access
bp-trace-memory – enable tracing of memory accesses
bp-wait-for-memory – wait for specified memory access
break – deprecated set breakpoint
tbreak – deprecated set temporary breakpoint on current processor
