2017-07-27ui: move qemu_input_linux_to_qcode()Gerd Hoffmann1-113/+0
Move from input-linux.c to input-keymap.c and export it, so the function is available elsewhere too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-id: 20170726152918.11995-3-kraxel@redhat.com
2017-05-11ui: input-linux: Add absolute event supportPhilippe Voinov1-1/+24
This patch adds support for absolute pointer events to the input-linux subsystem. This support was omitted from the original input-linux patch, however most of the code required for it is already in place. Support for absolute events is especially useful for guests with vga passthrough. Since they have a physical monitor, none of normal channels for sending video output (vnc, etc) are used, meaning they also can't be used to send absolute input events. This leaves QMP as the only option to send absolute input into vga passthrough guests, which is not its intended use and is not efficient. This patch allows, for example, uinput to be used to create virtual absolute input devices. This lets you build external systems which share physical input devices between guests. Without absolute input capability, such external systems can't seamlessly share pointer devices between guests.

2017-04-03Fix input-linux reading from deviceJavier Celaya1-5/+12
The evdev devices in input-linux.c are read in blocks of one whole event. If there are not enough bytes available, they are discarded, instead of being kept for the next read operation. This results in lost events, of even non-working devices. This patch keeps track of the number of bytes to be read to fill up a whole event, and then handle it. Changes from v1 to v2: - Fix: Calculate offset on each iteration Changes from v2 to v3: - Fix coding style - Store offset instead of bytes to be read Signed-off-by: Javier Celaya <jcelaya@gmail.com> Message-id: 20170327182624.2914-1-jcelaya@gmail.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2016-10-13input-linux: initialize key stateGerd Hoffmann1-2/+13
Query input device keys, initialize state accordingly, so the correct state is reflected in case any key is pressed at initialization time. There is a high chance for this to actually happen for the 'enter' key in case you start qemu with a terminal command (directly or virsh). When finding any pressed keys the input grab is delayed until all keys are lifted, to avoid confusing guest and host with appearently stuck keys.

2016-07-12input-linux: better capability checks, merge input_linux_event_{mouse, keyboard}Gerd Hoffmann1-45/+47
Improve capability checks (count keys and buttons), store results. Merge the input_linux_event_mouse and input_linux_event_keyboard functions into one, dispatch into input_linux_handle_mouse and input_linux_handle_keyboard depending on device capabilities. Allow calling both handle functions, so we can handle mice which also send key events, by routing those key events to the keyboard.

2016-03-24input-linux: switch over to -objectGerd Hoffmann1-33/+121
This patches makes input-linux use -object instead of a new command line switch. So, instead of the switch ... -input-linux /dev/input/event$nr ... you must create an object this way: -object input-linux,id=$name,evdev=/dev/input/event$nr Bonus is that you can hot-add and hot-remove them via monitor now.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-03-08input: linux evdev supportGerd Hoffmann1-0/+357
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.
