The Target Navigator lists the targets and, for the connected ones, the processes running on them. Through this view's controls, you can configure kernel event tracing and adaptive partitioning for targets and send signals to processes, attach the debugger to them, and adjust their scheduling properties.
This view is also used to select the process for which you want to view runtime data. When you click a process entry in the Target Navigator, several other System Information views are updated to show that process's statistics, as explained in “How data are displayed.”
The QNX System Information and QNX System Profiler perspectives automatically open this view but you can access it at any time through:
) in the toolbar along the top, you can access options for:
- grouping processes by PID family
- sorting processes by PID or name
- changing the refresh rate
- reversing the sorting order
(
) - disabling or re-enabling auto-refresh
(
) - manually refreshing the display
(
) - starting or configuring kernel event tracing
(
) - creating a new target connection
(
) - minimizing and maximizing the view
Interacting with targets
If you point to Attach As, the resulting submenu has two options: C/C++ QNX Attach to Process and Attach Configurations. For the first option, the IDE opens a window for selecting a process from a list. When you then do this, the IDE creates a launch configuration called attach.process_name and tries to launch it by attaching the debugger to the running process. For the second option, it opens a window for managing launch configurations, in which you can create your own attach configuration.
The Log With option lets you run a kernel event trace. From the APS submenu, you can configure the adaptive partitioning scheduler, as described below in “Configuring APS”. Finally, the Properties option opens the QNX Qconn Target panel for configuring the target connection.
Interacting with processes
Some target-level operations are still accessible from the process-level menu. These include refreshing the process list, creating a new connection, launching a kernel event trace, and displaying the target properties. Here, the Attach As option doesn't display a window with a process list—the IDE just creates the new attach configuration and tries to launch it to start debugging the selected process.
The middle portion of the menu shows options for interacting with processes. For example, you can send signals by clicking Deliver Signal and then, in the resulting popup window, selecting the appropriate signal from the dropdown list and clicking OK. You can explicitly terminate a process by selecting Slay. There are also options to adjust a process's priority and its inherited and non-inherited CPU affinities.
Each of these process options opens a popup window for setting the corresponding property. For information about scheduling priorities and policies, see the “Thread scheduling” section in the System Architecture guide. For information about the CPU affinity settings that associate threads with a particular core, see the “Thread affinity” section in the Programmer's Guide.
