gdbstub: Rework configuration via command line and monitor (Jan Kiszka)
Introduce a more canonical gdbstub configuration (system emulation only) via the new switch '-gdb dev'. Keep '-s' as shorthand for '-gdb tcp::1234'. Use the same syntax also for the corresponding monitor command 'gdbserver'. Its default remains to listen on TCP port 1234. Changes in v4: - Rebased over new command line switches meta file Changes in v3: - Fix documentation Changes in v2: - Support for pipe-based like to gdb (target remote | qemu -gdb stdio) - Properly update the qemu-doc Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6992 c046a42c-6fe2-441c-8c8c-71466251a162
