Hi Dan, from a quick search it seems xen/ia64 doesn''t have a GDB stub, is that right? (What exactly is pdb-stub about?) Looking at arch/x86/cdb.c, it seems that most of this code could be made common, and each architecture would supply its own version of handle_register_read_command/handle_memory_read_command(). Would that be useful to you? -- Hollis Blanchard IBM Linux Technology Center _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
That would be useful to a lot of people. I suggested that a while back but have been fighting other fires. PDB was a more complete and MUCH more brittle stub.

RE: [Xen-devel] common gdb stub
No, no gdb stub in xen/ia64 right now. The pdb-stub is vestigial... there used to be one in xen/x86 (a debugger that Alex Ho was doing, see http://www.cl.cam.ac.uk/~sos22/replay.bk/docs/misc/XenDebugger-HOWTO http://doi.ieeecomputersociety.org/10.1109/GRID.2004.49) and the routines in it were accessed from common. Because I''ve had the use of a good simulator, I haven''t had much use for an interactive debugger, but I''m sure it will become useful at some point. We had a similar gdb-stub in vBlades and it sometimes came in handy.
