Re: [Xen-devel] [RESEND] [PATCH] Use GDB 'O' packets for console output

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Sharing a single serial line between console and gdbstub isn't a mode we
particularly considered. Without something like this patch, I suppose
ordinary console output and gdb packets get mixed together on the line and
confuse the gdb session? Does gdb actually print out the console data with
your patch?

It's not nice to tell core serial code about the debugger. The switch
between raw output and output-via-gdbstub should be entirely in console.c.
