Emulate pointer warps by locking the pointer and sending relative
motion events instead of absolute. X will keep track of the "fake"
pointer cursor position given the relative motion events, and the
client warping the cursor will warp the faked cursor position.
Various requirements need to be met for the pointer warp emulator to
enable:
The cursor must be invisible: since it would not be acceptable that a
fake cursor position would be different from the visual representation
of the cursor, emulation can only be done when there is no visual
representation done by the Wayland compositor. Thus, for the emulator
to enable, the cursor must be hidden, and would the cursor be displayed
while the emulator is active, the emulator would be destroyed.
The window that is warped within must be likely to have pointer focus.
For example, warping outside of the window region will be ignored.
The pointer warp emulator will disable itself once the fake cursor
position leaves the window region, or the cursor is made visible.
This makes various games depending on pointer warping (such as 3D
first-person shooters and stategy games using click-to-drag-map like
things) work.

The checks in xwayland's XYToWindow handler pretty much assumes that the
sprite is managed by the wl_pointer, which is not entirely right, given
1) The Virtual Core Pointer may be controlled from other interfaces, and
2) there may be other SpriteRecs than the VCP's.
This makes XYToWindow calls return a sprite trace with just the root
window if any of those two assumptions are broken, eg. on touch events.
So turn the check upside down, first assume that the default XYToWindow
proc behavior is right, and later cut down the spriteTrace if the
current device happens to be the pointer and is out of focus. We work
our way to the device's lastSlave here so as not to break assumption #1
above.

The new platform bus code and the old PCI bus code overlap. Platform bus
can handle any type of device, including PCI devices, whereas the PCI code
can only handle PCI devices. Some drivers only support the old style
PCI-probe methods, but the primary device detection code is server based,
not driver based; so we might end up with a primary device which only has
a PCI bus-capable driver, but was detected as primary by the platform
code, or the other way around.
(The above paragraph was shamelessly stolen from Hans de Goede, and
customized.)
The latter case applies to QEMU's virtio-gpu-pci device: it is detected as
a BUS_PCI primary device, but we actually probe it first (with the
modesetting driver) through xf86platformProbeDev(). The
xf86IsPrimaryPlatform() function doesn't recognize the device as primary
(it bails out as soon as it sees BUS_PCI); instead, we add the device as a
secondary graphics card under "autoAddGPU". In turn, the success of this
automatic probing-as-GPU prevents xf86CallDriverProbe() from proceeding to
the PCI probing.
The result is that the server exits with no primary devices detected.
Commit cf66471353 ("xfree86: use udev to provide device enumeration for
kms devices (v10)") added "cross-bus" matching to xf86IsPrimaryPci(). Port
that now to xf86IsPrimaryPlatform(), so that we can probe virtio-gpu-pci
as a primary card in platform bus code.

That commit moved the setting of the extension in the extension bits from

__glXInitExtensionEnableBits can be used more generally, but at the same
time made the setting of EXT_texture_from_pixmap conditionally on

When using secondary GPU outputs the primary GPU's blockhandler
will copy changes from its framebuffer to a pixmap shared with the
secondary GPU.
In reverse prime setups the secondary GPU's blockhandler will do another
copy from the shared pixmap to its own framebuffer.
Before this commit, if the primary GPU's blockhandler would run after
the secondary GPU's blockhandler and no events were pending, then the
secondary GPU's blockhandler would not run until some events came in
(WaitForSomething() would block in the poll call), resulting in the
secondary GPU output sometimes showing stale contents (e.g. a just closed
window) for easily up to 10 seconds.
This commit fixes this by setting the timeout passed into the
blockhandler to 0 if any shared pixmaps were updated by the primary GPU,
forcing an immediate re-run of all blockhandlers.

before we start the second copy (before the secondary GPU's driver
starts processing the damage on the shared pixmap).
This fixes secondary outputs sometimes showning (some) old fb contents,
because of the 2 copies racing with each other, for an example of

In Xwayland's xwl_unrealize_cursor(), the x_cursor is cleared up only
when a device value is provided to the UnrealizeCursor() routine, but
if the device is NULL as called from FreeCursor(), the corresponding
x_cursor for the xwl_seat is left untouched.
This might cause a segfault when trying to access the unrealized
cursor's devPrivates in xwl_seat_set_cursor().
A possible occurrence of this is the client changing the cursor, the
Xserver calling FreeCursor() which does UnrealizeCursor() and then
the Wayland server sending a pointer enter event, which invokes
xwl_seat_set_cursor() while the seat's x_cursor has just been
unrealized.
To avoid this, walk through all the xwl_seats and clear up all x_cursor
matching the cursor being unrealized.

wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.
When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.
The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.
What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.
This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.
Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.
