tasks — Displays task threads currently running on system.
tasks
ABLE runs several threads to control various hardware devices. This command displays the currently running threads.
The information is presented in a tabular form. The columns are:
| Task name and address |
| Priority of execution |
| Current state |
| Register context block |
| Time thread was last scheduled |
The scheduling for the threads is a simple “round robin” method which suffices for ABLE requirements.
Example 45. Using the tasks command
This example shows the tasks command when run on a EB2410ITX. The showhz command is used to show the current system time which is the same as used in the “Last Run” column. It shows the Ethernet PHY control task, the USB host controller driver, the reaper task to clean up after other tasks, the init task which starts the system and the main task which typically runs the autoboot or interactive shell.
