Thanks for CC Konrad, I'm gazillions postings behind in catching up
xen-devel.
Bruce, you don't need to use the ext repo anymore as gdbsx is now
merged mainline. I should update the blog post.
To build a debug enabled xen image: make gdbsx=y is all you need
to do. After booting with gdbsx enabled xen, you can run gdbsx in
dom0. See tools/debugger/gdbsx/README.
Note, you don't need to do anything in tools/debugger/gdb and/or
gdbbuild. tools/debugger/gdb (gdbbuild) is unlreated to gdbsx.
Perhaps, we should just remove tools/debugger/gdb if it's not being
maintained and no one is using it.
thanks,
Mukesh
