Debugging Dom-0/Dom-U User Space Processes

  1. Boot Xen and Dom-0.
    For details on how to boot Xen and Dom-0, refer UG1144 - PetaLinux Tools Documentation: Reference Guide.
  2. Enable Xen awareness by enabling OS aware debug for Xen symbol file. Symbol files are added to a process context to enable source level debugging.
    For details on how to enable Xen awareness, refer Enabling Xen Awareness.
  3. Create a Linux application project.
    For details on how to create a Linux application project, refer Creating a Linux Application Project.
  4. Configure the Dom-0 user space process by adding the symbol file of the application running on Linux for the debug context of the virtual CPU (VCPU#) of the host domain (Dom-0).


  5. Configure Dom-U user space process.
    1. Copy the guest Linux images to Dom-0 file system.
    2. Create the Lilnux guests with para-virtual networking. 
          name = "guest 0"
    kernel = "/boot/Image"
    extra = "console=hvc0 rdinit=/sbin/init"
    memory = 256
    vcpus = 2
    vif = [ 'bridge=xenbr0' ]
    3. Add the symbol file of the application running on Linux for the debug context of the virtual cpu (VCPU#) of the guest domain (Dom-U).
  6. Once the symbol files are set, you can insert breakpoints, step in, step out, watch variables, stack trace or perform other source level debugging tasks.
