(this section is only here temporarily)

  • target agents:
    • connectors:
      • adb
      • what do WR, MV and others use to set up or connect the debugger to the process?
    • debug agents
      • gdbserver
      • kgdb
  • host agents:
    • adb server
  • debuggers:
    • gdb
    • kdb (local interactive kernel debugging)
