This series is intended to alow HVM guests to use the vkbd device with a PV frontend driver. Initial version at: http://xenbits.xen.org/gitweb/?p=pvdrivers/win/xenvkbd.git;a=tree Since the vkbd device is initialised for HVM guests, using the vkbd device can allow the disabling of the USB controller and USB tablet and maintaining the same easy to use absolute pointer. The main problem, is that the vkbd device does not connect unless a vfb device is present, to facilitate the rescaling of absolute coordinates. This series rearranges the input handlers to use the qemu_input_handler_* functions, by using the callbacks directly, rather than via the compatability layer in input-legacy.c. The series also registers the "feature-raw-pointer" feature to indicate the backend can supply raw unscaled absolute cordinates. The frontend uses "request-raw-pointer" to request raw unscaled values. Adding the feature is also to enable detecting the difference between older, broken, backend and newer backends that can connect without the vfb present. v2: * reworks the input handlers to use qemu_input_handler_* functions * rename the feature proposed to a better name - the name better reflects the intended use-case (raw pointer vs backend requires vfb device) Owen Smith (2): xenfb: Use qemu_input_handler_* calls directly xenfb: Allow vkbd to connect without a DisplayState hw/display/xenfb.c | 157 +++++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 139 insertions(+), 18 deletions(-) -- 2.1.4 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
