2016-06-20vl: Error messages need to go to stderr, fix someMarkus Armbruster
We print a few fatal error messages to stdout instead of stderr. Reproducer: $ qemu-system-x86_64 -g 1024x768 Option g not supported for this target $ qemu-system-x86_64 -g 1024x768 >/dev/null Fix by printing them with error_report().

2016-06-17vnc: Wrap vnc initialization code with CONFIG_VNCChao Peng
commit f8c75b2486 (vnc: Initialization stubs) removed CONFIG_VNC in vl.c code. However qemu_find_opts("vnc") is NULL when vnc is configured out. Crash will happen in qemu_opts_foreach() before stub vnc_init_func() is called. This patch add it back.

2016-06-16vl.c: Add '-L help' which lists data dirs.Richard W.M. Jones
QEMU compiles a list of data directories from various sources. When consuming a QEMU binary it's useful to be able to get this list of data directories: a primary reason is so you can list what BIOSes or keymaps ship with this version of QEMU. However without reproducing the method that QEMU uses internally, it's not possible to get the list of data directories. This commit adds a simple '-L help' option that just lists out the data directories as qemu calculates them: $ ./x86_64-softmmu/qemu-system-x86_64 -L help /home/rjones/d/qemu/pc-bios /usr/local/share/qemu $ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help /tmp /home/rjones/d/qemu/pc-bios /usr/local/share/qemu Signed-off-by: Richard W.M.

The only case where DT_SDL is used outside a #ifdef CONFIG_SDL block is in the no_frame/alt_grab/ctrl_grab check. That means the only user-visible change is that we will start printing a warning if the SDL-specific options are used in Cocoa mode. This is a bugfix, because no_frame/alt_grab/ctrl_grab are not used by Cocoa code.

2016-04-28qom: -object error messages lost location, restore itMarkus Armbruster
qemu_opts_foreach() runs its callback with the error location set to the option's location. Any errors the callback reports use the option's location automatically. Commit 90998d5 moved the actual error reporting from "inside" qemu_opts_foreach() to after it. Here's a typical hunk: if (qemu_opts_foreach(qemu_find_opts("object"), - object_create, - object_create_initial, NULL)) { + user_creatable_add_opts_foreach, + object_create_initial, &err)) { + error_report_err(err); exit(1); } Before, object_create() reports from within qemu_opts_foreach(), using the option's location. Afterwards, we do it after qemu_opts_foreach(), using whatever location happens to be current there. Commonly a "none" location. This is because Error objects don't have location information. Problematic. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -object secret,id=foo,foo=bar qemu-system-x86_64: Property '.foo' not found Note no location. This commit restores it: qemu-system-x86_64: -object secret,id=foo,foo=bar: Property '.foo' not found Note that the qemu_opts_foreach() bug just fixed could mask the bug here: if the location it leaves dangling hasn't been clobbered, yet, it's the correct one.

2016-04-05vl: Move cpu_synchronize_all_states() into qemu_system_reset()David Gibson
There are currently 3 calls to qemu_system_reset() in vl.c. Two of them are immediately preceded by a cpu_synchronize_all_states9) and the remaining one should be. The one which doesn't is the very first reset called directly from main(). Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this point from the earlier cpu_synchronize_all_post_init(). That's incorrect because the reset path is quite likely to update the CPU state, and that updated state should be pushed back to KVM, not overwritten with stale data pushed to KVM immediately after init. This patch moves the call to cpu_synchronize_all_states() into qemu_system_reset() for safety, so it is always called. AFAICT this should be safe for the handful of callers outside vl.c - these all appear to be in places where the cpu state is already synchronized so the extra call will be a no-op.

2016-03-08input: linux evdev supportGerd Hoffmann
This patch adds support for reading input events directly from linux evdev devices and forward them to the guest. Unlike virtio-input-host which simply passes on all events to the guest without looking at them this will interpret the events and feed them into the qemu input subsystem. Therefore this is limited to what the qemu input subsystem and the emulated input devices are able to handle. Also there is no support for absolute coordinates (tablet/touchscreen). So we are talking here about basic mouse and keyboard support. The advantage is that it'll work without virtio-input drivers in the guest, the events are delivered to the usual ps/2 or usb input devices (depending on what the machine happens to have). And for keyboards qemu is able to switch the keyboard between guest and host on hotkey. The hotkey is hard-coded for now (both control keys), initialy the guest owns the keyboard. Probably most useful when assigning vga devices with vfio and using a physical monitor instead of vnc/spice/gtk as guest display. Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command line. Note that udev has rules which populate /dev/input/by-{id,path} with static names, which might be more convinient to use.

2016-02-19vl: Reset location after handling command-line argumentsEduardo Habkost
After looping through all command-line arguments, error location info becomes obsolete, and any function calling error_report() will print misleading information. This breaks error reporting for some option handling, like: $ qemu-system-x86_64 -icount rr=x -vnc :0 qemu-system-x86_64: -vnc :0: Invalid icount rr option: x $ qemu-system-x86_64 -m size= -vnc :0 qemu-system-x86_64: -vnc :0: missing 'size' option value Fix this by resetting location info as soon as we exit the command-line handling loop. With this, replay_configure() and set_memory_options() won't print any location info yet, but at least they won't print incorrect information.

2016-02-19vl.c: Fix regression in machine error messageMarcel Apfelbaum
Commit e1ce0c3cb (vl.c: fix regression when reading machine type from config file) fixed the error message when the machine type was supplied inside the config file. However now the option name is not displayed correctly if the error happens when the machine is specified at command line. Running ./x86_64-softmmu/qemu-system-x86_64 -M q35-1.5 -redir tcp:8022::22 will result in the error message: qemu-system-x86_64: -redir tcp:8022::22: unsupported machine type Use -machine help to list supported machines Fixed it by restoring the error location and also extracted the code dealing with machine options into a separate function.

2016-02-16qom: add helpers for UserCreatable object typesDaniel P. Berrange
The QMP monitor code has two helper methods object_add and qmp_object_del that are called from several places in the code (QMP, HMP and main emulator startup). The HMP and main emulator startup code also share further logic that extracts the qom-type & id values from a qdict. We soon need to use this logic from qemu-img, qemu-io and qemu-nbd too, but don't want those to depend on the monitor, nor do we want to duplicate the code. To avoid this, move some code out of qmp.c and hmp.c adding new methods to qom/object_interfaces.c - user_creatable_add - takes a QDict holding a full object definition & instantiates it - user_creatable_add_type - takes an ID, type name, and QDict holding object properties & instantiates it - user_creatable_add_opts - takes a QemuOpts holding a full object definition & instantiates it - user_creatable_add_opts_foreach - variant on user_creatable_add_opts which can be directly used in conjunction with qemu_opts_foreach. - user_creatable_del - takes an ID and deletes the corresponding object The existing code is updated to use these new methods.
