====== Stefan Hajnoczi: GDB Remote Debugging ====== ===== Week 3 ===== **Milestones:** * GDB remote debugging over UDP. * Hardware watchpoint support for trapping read/write/execute on memory. ==== Mon Jun 9 ==== I had a refreshing weekend with only a little bit of Etherboot hacking on Saturday. The weather was excellent and I was able to recharge batteries a bit :-). The past two weeks of Summer of Code have been an excellent experience. I've had the chance to look behind the scenes of Etherboot and to pitch in and help out. My current focus is on GDB remote debugging over UDP. I think this feature will be very useful since it let's you debug gPXE without using a serial cable. It opens the door to letting developers analyze errors over the internet without having to reproduce them locally from a bug report. I'd really like to see this used in cases where developers do not have hardware on which the error occurs. The core of the UDP code is currently emerging, hopefully I'll have a working commit later today. Next steps: * Implement UDP transport. * Implement hardware watchpoint support using debug registers. * NULL pointer bug guard using watchpoint support. * SSL wiki login. * Use screen captures on [[:dev:gdbstub|GDB stub page]].
