Our 'file' chardev backend supports both "output from this chardev is written to a file" and "input from this chardev should be read from a file" (except on Windows). However, you can only set up the input file if you're using the QMP interface -- there is no command line syntax to do it.
Add command line syntax to allow specifying an input file as well as an output file, using a new 'input-path' suboption.
The specific use case I have is that I'd like to be able to feed fuzzer reproducer input into qtest without having to use '-qtest stdio' and put the input onto stdin. Being able to use a file chardev like this: -chardev file,id=repro,path=/dev/null,input-path=repro.txt -qtest chardev:repro means that stdio is free for use by gdb.
