[Qemu-devel] WinDbg module

/releases/tag/v2.7.50-windbg Currently only one ways to create a remote debugging connection is supported: using COM port with named pipe. Should I prepare patches for inclusion in the master branch? Or is it too specific module and it is not needed? -- Thanks, Mihail Abakumov
