Chapter 15. Debugging Tools

This chapter provides information about the available procedures for debugging a device driver which is under development. The procedures discussed include:

• Saving device driver information in a system dump.
• Using the crash command to interpret and format system structures.
• Using the kernel debugger to set breakpoints and display variables and registers.
• Error logging to record device-specific hardware or software abnormalities.
• Using the trace facility to monitor entry and exit of device drivers and selectable system events.
