[Qemu-devel] [PATCH 0/3] input: add keys and mouse buttons to virtio input

[Miika S]

This patchset adds some missing keys and mouse buttons to
hw/input/virtio-input-hid.c.

On a JIS keyboard such as this one (106/109 - JIS)
https://upload.wikimedia.org/wikipedia/commons/b/b2/Physical_keyboard_layouts_comparison_ANSI_ISO_KS_ABNT_JIS.png
the keys are located as follows:
muhenkan: left of spacebar
henkan: right of spacebar
katakanahiragana: right of henkan
compose: the same as menu but the existing one didn't work
ro: left of right shift
    (this produces the same key code as the key right of left shift on
    102/105 ISO keyboard in the linked picture and consequently this
    patch also adds support for those keyboards)
yen: left of backspace

The mouse buttons "side" and "extra" are the ones you use to go to the
previous and next page in modern web browsers such as Firefox and
Chrome.

The last patch fixes mouse wheel event sent for both button up and down
by only forwarding the event when the button state is down.

[Qemu-devel] [PATCH 3/3] input: virtio: don't send mouse wheel event twice

[Miika S]

On Linux, a mouse event is generated for both down and up when mouse
wheel is used. This caused virtio_input_send() to be called twice each
time the wheel was used.

This commit adds a check for the button down state and only calls
virtio_input_send() when it is true.

  Hi,

Cherry-picked these two ad the kbd update depends on the not-yet merged
keycodemapdb update for virtio-keyboard.

thanks,
  Gerd

It is merged actually in, so you can include the keycode fix too:

https://git.qemu.org/gitweb.cgi?p=keycodemapdb.git;a=commit;h=05dad417e9d0b37ee1fba33056d91a6b734b3357

To be exact: it conflicts (and I think also is obsoleted by) your patch
"hw: convert virtio-input-hid device to keycodemapdb".

That patch doesn't touch keycodemapdb.

I did obsolete it though in an unrelated series:

  https://lists.gnu.org/archive/html/qemu-devel/2018-01/msg03528.html

You should be fine to just include all 3 of the patches in this series,
if you do a pull request for this series, before that py3 series gets
pulled.

Daniel
