Since commit 9894dc0cdcc397ee5b26370bc53da6d360a363c2 "char: convert from GIOChannel to QIOChannel", the first argument to the watch callback can actually be a QIOChannel, which is not a GIOChannel (but a QEMU Object). Even though we never used that pointer, change the callback type to warn the users. Possibly a better fix later, we may want to store the callback and call it from intermediary functions.

2021-07-29ppc/vof: Fix Coverity issuesAlexey Kardashevskiy
Coverity reported issues which are caused by mixing of signed return codes from DTC and unsigned return codes of the client interface. This introduces PROM_ERROR and makes distinction between the error types. This fixes NEGATIVE_RETURNS, OVERRUN issues reported by Coverity. This adds a comment about the return parameters number in the VOF hcall. The reason for such counting is to keep the numbers look the same in vof_client_handle() and the Linux (an OF client). vmc->client_architecture_support() returns target_ulong and we want to propagate this to the client (for example H_MULTI_THREADS_ACTIVE). The VOF path to do_client_architecture_support() needs chopping off the top 32bit but SLOF's H_CAS does not; and either way the return values are either 0 or 32bit negative error code. For now this chops the top 32bits. This makes "claim" fail if the allocated address is above 4GB as the client interface is 32bit. This still allows claiming memory above 4GB as potentially initrd can be put there and the client can read the address from the FDT's "available" property.

2021-07-26ui/gtk: add a keyboard fifo to the VTE consolesVolker Rümelin
Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple characeters") it's very easy to lock up QEMU with the GTK ui. If you configure a guest with a serial device and the guest doesn't listen on this device, QEMU will lock up after entering two characters in the serial console. That's because current code uses a busy loop for the chardev write retries and the busy loop doesn't terminate in this case. To fix this problem add a fifo to the VTE consoles and use the chr_accept_input() callback function to write the remaining characters in the queue to the chardev. The fifo has a size of 4096 bytes, so one can copy and paste a fairly large URL or file path.

2021-07-23tcg/plugins: implement a qemu_plugin_user_exit helperAlex Bennée
In user-mode emulation there is a small race between preexit_cleanup and exit_group() which means we may end up calling instrumented instructions before the kernel reaps child threads. To solve this we implement a new helper which ensures the callbacks are flushed along with any translations before we let the host do it's a thing. While we are at it make the documentation of qemu_plugin_register_atexit_cb clearer as to what the user can expect.

2021-07-23qapi: introduce forwarding visitorPaolo Bonzini
This new adaptor visitor takes a single field of the adaptee, and exposes it with a different name. This will be used for QOM alias properties. Alias targets can of course have a different name than the alias property itself (e.g. a machine's pflash0 might be an alias of a property named 'drive'). When the target's getter or setter invokes the visitor, it will use a different name than what the caller expects, and the visitor will not be able to find it (or will consume erroneously). The solution is for alias getters and setters to wrap the incoming visitor, and forward the sole field that the target is expecting while renaming it appropriately.

Before commit 49afbca3b00e8e517d54964229a794b51768deaf ("virtio-gpu: drop use_virgl_renderer"), use_virgl_renderer was preventing calling GL functions from non-GL context threads. The innocuously looking g->parent_obj.use_virgl_renderer = false; was set the first time virtio_gpu_gl_reset() was called, during pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset() calls in IO threads, without associated GL context, were thus skipping GL calls and avoided warnings or crashes (see also https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

The `aio-max-batch` parameter will be propagated to AIO engines and it will be used to control the maximum number of queued requests. When there are in queue a number of requests equal to `aio-max-batch`, the engine invokes the system call to forward the requests to the kernel. This parameter allows us to control the maximum batch size to reduce the latency that requests might accumulate while queued in the AIO engine queue. If `aio-max-batch` is equal to 0 (default value), the AIO engine will use its default maximum batch size value.

2021-07-19hw/ide: Fix crash when plugging a piix3-ide device into the x-remote machineThomas Huth
QEMU currently crashes when the user tries to do something like: qemu-system-x86_64 -M x-remote -device piix3-ide This happens because the "isabus" variable is not initialized with the x-remote machine yet. Add a proper check for this condition and propagate the error to the caller, so we can fail there gracefully.

This does involve a uintptr_t cast of the result of the TLB addend as we know that has to point to the host memory.
