chardev: use bool for fe_is_open The function qemu_chr_fe_init already treats be->fe_open as a bool and if it acts like a bool it should be one.

chardev: Allow setting file chardev input file on the command line 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.

QIOChannel: Add flags on io_writev and introduce io_flush callback Add flags to io_writev and introduce io_flush as optional callback to QIOChannelClass, allowing the implementation of zero copy writes by subclasses. How to use them: - Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY), - Wait write completion with qio_channel_flush(). Notes: As some zero copy write implementations work asynchronously, it's recommended to keep the write buffer untouched until the return of qio_channel_flush(), to avoid the risk of sending an updated buffer instead of the buffer state during write. As io_flush callback is optional, if a subclass does not implement it, then: - io_flush will return 0 without changing anything. Also, some functions like qio_channel_writev_full_all() were adapted to receive a flag parameter. That allows shared code between zero copy and non-zero copy writev, and also an easier implementation on new flags. Signed-off-by: Leonardo Bras <leobras@redhat.com> Reviewed-by: Daniel P.

chardev: don't exit() straight away on C-a x While there are a number of uses in the code-base of the exit(0) pattern it gets in the way of clean exit which can do all of it's house-keeping. In particular it was reported that you can crash plugins this way because TCG can still be running on other threads when the atexit callback is called. Use qmp_quit() instead which takes care of some housekeeping before triggering the shutdown.

chardev/char-pty: Avoid losing bytes when the other side just (re-)connected When starting a guest via libvirt with "virsh start --console ...", the first second of the console output is missing. This is especially annoying on s390x that only has a text console by default and no graphical output - if the bios fails to boot here, the information about what went wrong is completely lost. One part of the problem (there is also some things to be done on the libvirt side) is that QEMU only checks with a 1 second timer whether the other side of the pty is already connected, so the first second of the console output is always lost. This likely used to work better in the past, since the code once checked for a re-connection during write, but this has been removed in commit f8278c7d74 ("char-pty: remove the check for connection on write") to avoid some locking. To ease the situation here at least a little bit, let's check with g_poll() whether we could send out the data anyway, even if the connection has not been marked as "connected" yet. The file descriptor is marked as non-blocking anyway since commit fac6688a18 ("Do not hang on full PTY"), so this should not cause any trouble if the other side is not ready for receiving yet. With this patch applied, I can now successfully see the bios output of a s390x guest when running it with "virsh start --console" (with a patched version of virsh that fixes the remaining issues there, too).

qapi chardev: Elide redundant has_FOO in generated C The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/char.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

trace: switch position of headers to what Meson requires Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.
