Hi > I would like to try to connect some serial hardware simulation to a standard > serial port within qemu. Everything should run within qemu. I found the answer and just to make the people happy using search engines here is the answer:
There are backends which already implement serial hardware. They can be found under backends/. Especially msmouse.c and baum.c realize serial hardware which give a nice example how to connect to a qemu system. qapi-schema.json needs to be adaped similar to msmouse. And i guess the function qemu_chr_parse_compat in qemu-char.c needs also a new strcmp matching the new device name. qemu-options.hx also seems to need some changes. Currently unclear is to me is how the argument parsing callback works and how serial_hds should be replaced by properties? Any pointers are welcome. Best regards Tim
