2017-12-14xenfb: activate input handlers for raw pointer devicesOwen Smith
If the frontend requests raw pointers, the input handlers must be activated to have the input events delivered to the xenfb backend. Without activation, the input events are delivered to handlers registered earlier, which would be the emulated USB tablet or emulated PS/2 mouse. HVM xen_kbdfront can incorrectly scale absolute coordinates when the display resolution is not 800x600.

Writes "feature-raw-pointer" during init to indicate the backend can pass raw unscaled values for absolute axes to the frontend. Frontends set "request-raw-pointer" to indicate the backend should not attempt to scale absolute values to console size. "request-raw-pointer" is only valid if "request-abs-pointer" is also set. Raw unscaled pointer values are in the range [0, 0x7fff] "feature-raw-pointer" and "request-raw-pointer" added to Xen header in commit 7868654ff7fe5e4a2eeae2b277644fa884a5031e Signed-off-by: Owen Smith <owen.smith@citrix.com> Reviewed-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Signed-off-by: Stefano Stabellini <sstabellini@kernel.org>

2017-10-17vga: handle cirrus vbe mode wraparounds.Gerd Hoffmann
Commit "3d90c62548 vga: stop passing pointers to vga_draw_line* functions" is incomplete. It doesn't handle the case that the vga rendering code tries to create a shared surface, i.e. a pixman image backed by vga video memory. That can not work in case the guest display wraps from end of video memory to the start. So force shadowing in that case. Also adjust the snapshot region calculation. Can trigger with cirrus only, when programming vbe modes using the bochs api (stdvga, also qxl and virtio-vga in vga compat mode) wrap arounds can't happen.

2017-07-25hw/display/sm501: Don't use vmstate_register_ram_global()Peter Maydell
The sm501 device uses vmstate_register_ram_global() to register its memory region for migration. This means it gets a name that is assumed to be global to the whole system, which in turn means that if you create two of the device we assert because of the duplication: qemu-system-ppc -device sm501 -device sm501 RAMBlock "sm501.local" already registered, abort! Aborted (core dumped) Changing this to just use memory_region_init_ram()'s automatic registration of the memory region with a device-local name fixes this. The downside is that it breaks migration compatibility, but luckily we only added migration support to this device in the 2.10 release cycle so we haven't released a QEMU version with the broken implementation.

2017-07-14qom: enforce readonly nature of link's check callbackIgor Mammedov
link's check callback is supposed to verify/permit setting it, however currently nothing restricts it from misusing it and modifying target object from within. Make sure that readonly semantics are checked by compiler to prevent callback's misuse.

2017-07-07xenfb: remove xen_init_display "temporary" hackStefano Stabellini
Initialize xenfb properly, as all other backends, from its own "initialise" function. Remove the dependency of vkbd on vfb: use qemu_console_lookup_by_index to find the principal console (to get the size of the screen) instead of relying on a vfb backend to be available (which adds a dependency between the two).

2017-06-28vmstate: error hint for failed equal checksHalil Pasic
In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug, but it's actually the best we can do. Especially in these cases a verbose error message is required. Let's introduce infrastructure for specifying a error hint to be used if equal check fails. Let's do this by adding a parameter to the _EQUAL macros called _err_hint. Also change all current users to pass NULL as last parameter so nothing changes for them.
