Keith Packard 8de702cb67 semihosting: add qemu_semihosting_console_inc for SYS_READC ... Provides a blocking call to read a character from the console using semihosting.chardev, if specified. This takes some careful command line options to use stdio successfully as the serial ports, monitor and semihost all want to use stdio. Here's a sample set of command line options which share stdio between semihost, monitor and serial ports: qemu \ -chardev stdio,mux=on,id=stdio0 \ -serial chardev:stdio0 \ -semihosting-config enable=on,chardev=stdio0 \ -mon chardev=stdio0,mode=readline This creates a chardev hooked to stdio and then connects all of the subsystems to it. A shorter mechanism would be good to hear about.
