Description Guo, Zhiyi 2017-11-13 09:42:49 UTC 
Description of problem:
Media keys are missing for qemu usb-kbd

Version-Release number of selected component (if applicable):
host & guest: 3.10.0-781.el7.x86_64
qemu-kvm-rhev-2.10.0-5.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Boot a rhel7.5 guest with usb-kbd:
/usr/libexec/qemu-kvm -name input-test -m 2G \
-cpu qemu64,check \
-smp 2 \
-device cirrus-vga \
-netdev tap,id=idinWyYp,vhost=on -device virtio-net-pci,mac=42:ce:a9:d2:4d:d7,id=idlbq7eA,netdev=idinWyYp \
-uuid 215e11b2-a869-41b5-91cd-6a32a907be7e \
-device ich9-usb-uhci6 \
-drive file=/home/rhel75.qcow2,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=stop  -device ide-drive,drive=drive-scsi-disk0 \
-qmp unix:/tmp/input-port,server,nowait \
-monitor stdio \
-device usb-kbd \
2.Inside guest, open gnome-terminal,execute 'showkey -k | grep press' and try to input media keys, keys I used are:
'NEXTSONG',
'PREVIOUSSONG',
'STOPCD',
'PLAYPAUSE',
'MUTE',
'VOLUMEUP',
'VOLUMEDOWN',
'MAIL',
'CALC',
'COMPUTER',
'SEARCH',
'HOMEPAGE',
'BACK',
'FORWARD',
'STOP',
'REFRESH',
'FAVORITES'
3.After input finish, wait for 10s for showkey to terminate and check the output of showkey

Actual results:
No output from showkey

Expected results:
the keycode of media keys output here:
keycode 163 press
keycode 165 press
keycode 166 press
keycode 164 press
keycode 113 press
keycode 115 press
keycode 114 press
keycode 155 press
keycode 140 press
keycode 157 press
keycode 217 press
keycode 172 press
keycode 158 press
keycode 159 press
keycode 128 press
keycode 173 press

Additional info:
ps2-kbd has all these keys. vnc/spice won't affect the result.

Comment 3 Gerd Hoffmann 2018-08-10 12:04:50 UTC 
please retest with a 2.12 build.

> please retest with a 2.12 build.

Use emulate-key tools(command # ./emulate-key -v NEXTSONG) to retest with qemu-kvm-rhev-2.12.0-7.el7.x86_64,
and keys I sent to guest from host(login by ssh on another host) are:
'NEXTSONG',
'PREVIOUSSONG',
'STOPCD',
'PLAYPAUSE',
'MUTE',
'VOLUMEUP',
'VOLUMEDOWN',
'MAIL',
'CALC',
'COMPUTER',
'SEARCH',
'HOMEPAGE',
'BACK',
'FORWARD',
'STOP',
'REFRESH',
'FAVORITES'

Inside guest gnome terminal, there is no output except the three keys below.
key 'MUTE' outputs a mute icons,
key 'VOLUMEUP' output a volume icons and do volume up,
key 'VOLUMEDOWN' output a volume icons and do volume down.


Does emulate-key tool have any update ?

You can use "input-events" inside the guest to see all key events, even in case they are not causing any visible action (like the volume keys do).

Use "input-events" inside the guest have the same result with media keys of Comment 4.
Besides, sometimes guest have more than Comment 4 media keys that can show actions,but this is low probability.

QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
