2020-09-18qom: Remove module_obj_name parameter from OBJECT_DECLARE* macrosEduardo Habkost
One of the goals of having less boilerplate on QOM declarations is to avoid human error. Requiring an extra argument that is never used is an opportunity for mistakes. Remove the unused argument from OBJECT_DECLARE_TYPE and OBJECT_DECLARE_SIMPLE_TYPE. Coccinelle patch used to convert all users of the macros: @@ declarer name OBJECT_DECLARE_TYPE; identifier InstanceType, ClassType, lowercase, UPPERCASE; @@ OBJECT_DECLARE_TYPE(InstanceType, ClassType, - lowercase, UPPERCASE); @@ declarer name OBJECT_DECLARE_SIMPLE_TYPE; identifier InstanceType, lowercase, UPPERCASE; @@ OBJECT_DECLARE_SIMPLE_TYPE(InstanceType, - lowercase, UPPERCASE); Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Cédric Le Goater <clg@kaod.org> Acked-by: Cornelia Huck <cohuck@redhat.com> Acked-by: Igor Mammedov <imammedo@redhat.com> Acked-by: Paul Durrant <paul@xen.org> Acked-by: Thomas Huth <thuth@redhat.com> Message-Id: <20200916182519.415636-4-ehabkost@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2020-09-09Move QOM typedefs and add missing includesEduardo Habkost
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2019-05-10Add vhost-user-input-pciMarc-André Lureau
Add a new virtio-input device, which connects to a vhost-user backend. Instead of reading configuration directly from an input device / evdev (like virtio-input-host), it reads it over vhost-user protocol with {SET,GET}_CONFIG messages. The vhost-user-backend handles the queues & events setup.

2017-09-29virtio-input: send rel-wheel events for wheel buttonsGerd Hoffmann
qemu uses wheel-up/down button events for mouse wheel input, however linux applications typically want REL_WHEEL events. This fixes wheel with linux guests. Tested with X11/wayland, and windows virtio-input driver. Based on a patch from Marc. Added property to enable/disable wheel axis.

2017-03-27virtio-input: fix eventq batchingLadi Prosek
virtio_input_send buffers input events until it sees a SYNC. Then it either sends or drops the entire batch, depending on whether eventq has enough space available. The case to avoid here is partial sends where only part of the batch would get to the guest. Using virtqueue_get_avail_bytes to check the state of eventq was not correct. The queue may have a smaller number of larger buffers available so bytes may be enough but the batch would still not be possible to send, leading to the "Huh? No vq elem available" error. Instead of checking available bytes, this patch optimistically pops buffers from the queue and puts them back in case it runs out of space and the batch needs to be dropped.

2015-06-23virtio-input: evdev passthroughGerd Hoffmann
This allows to assign host input devices to the guest: qemu -device virtio-input-host-pci,evdev=/dev/input/event<nr> The guest gets exclusive access to the input device, so be careful with assigning the keyboard if you have only one connected to your machine.

2015-06-23virtio-input: move properties, use virtio_instance_init_commonGerd Hoffmann
Move properties from virtio-*-pci to virtio-*-device. Also make better use of QOM and attach common properties to the abstract parent classes (virtio-input-device and virtio-input-pci-device). Switch the hid device instance init functions over to use virtio_instance_init_common, so we get the properties of the virtio device aliased properly to the virtio pci proxy.

2015-05-29virtio-input: emulated devices [device]Gerd Hoffmann
This patch adds the virtio-input-hid base class and virtio-{keyboard,mouse,tablet} subclasses building on the base class. They are hooked up to the qemu input core and deliver input events to the guest like all other hid devices (ps/2 kbd, usb tablet, ...). Using them is as simple as adding "-device virtio-tablet-device" to your command line, for use all transports except pci. virtio-pci support comes as separate patch, once virtio-pci got virtio 1.0 support.
