f67918353a hw/xwin: Improve performance of -compositewm
I think that a major cost in the current implementation is doing a
CreateDIBSection()/DestroyObject() on every refresh.  So provide our own
CreatePixmap() instead, which does the CreateDIBSection(), once.

Testcase: glxgears or foobillard with direct swrast
Testcase: scrolling in a full-screen xterm

v2:
Fix handling of RENDER Scratch Pixmaps
(A problem easily shown with gitk or emacs)

v3:
Note that we don't own screen pixmap to release in DestroyPixmap
Log if unimplemented slow-path ever gets hit

ebcea16e71 hw/xwin: A simpleminded attempt at composition
Rather than drawing the window contents from the shadow framebuffer, use
Composite extension redirection to cause the server to maintain a bitmap
image of each top-level X window, and draw the window contents from
that, so that window contents which are occluded in the framebuffer show
correctly in the task bar and task switcher previews.

v2:
Fix incorrect use of memset() found by gcc5

hw/xwin/winshadgdi.c: In function ‘winBltExposedWindowRegionShadowGDI’:
hw/xwin/winshadgdi.c:861:9: warning: ‘memset’ used with constant zero length parameter; this could be due to transposed parameters [-Wmemset-transposed-args]

v3:
Turn on -compositewm by default

v4:
Ignore -swcursor if -compositewm

-swcursor is not compatible with -compositewm (because the window
contents are drawn from an off-screen pixmap, not from the screen
pixmap, where the software cursor will be drawn).

v5:
Update meson.build also
Add -compositewm option to help output
Update CI to install prerequisites

Note that winBltExposedRegionsShadowGDI() is currently used 1) in

dea4a74621 xwayland: Reset scheduled frames after hiding tablet cursor
Hiding the tablet tool cursor results in it being hidden forever after.
This is due to the stale frame callback that will neither be disposed
or replaced. This can be reproduced in krita (X11) as the pointer
cursor is hidden while over the canvas.

Clearing the frame callback ensures the correct behavior in future
xwl_tablet_tool_set_cursor() calls (i.e. a new cursor surface being
displayed, and a new frame callback created), and is 1:1
with xwl_seat_set_cursor() for pointers.

fc6380a11b xwayland: Check status in GBM pixmap creation
The current code in `xwl_glamor_gbm_create_pixmap_for_bo()` may fail in
several cases that are not checked for:

 - `eglCreateImageKHR()` may have failed to create the image,
 - `glEGLImageTargetTexture2DOES()` may fail and set an error,
 - `glamor_set_pixmap_texture()` may fail for very large pixmaps
    because the corresponding FBO could not be created.

Trying to upload content to a pixmap with no texture will crash Mesa,
glamor and Xwayland, e.g.:

8469241592 xwayland: Add EGL-backed GLX provider
Without this we're using driswrast to set up GLX visuals. This is
unfortunate because llvmpipe does not expose multisample configs, so
various apps that expect them will fail. With this we just query the
capabilities of the EGL that's backing glamor, and reflect that to the
GLX clients. This also paves the way for xserver to stop being a DRI
driver loader, which is nice.

0a07446318 xwayland: Avoid a crash on pointer enter with a grab
On pointer enter notification, Xwayland checks for an existing pointer
warp with a `NULL` sprite.

In turn, `xwl_pointer_warp_emulator_maybe_lock()` checks for an existing
grab and the destination window using `XYToWindow()` which does not
check for the actual sprite not being `NULL`.

So, in some cases, when the pointer enters the surface and there is an
existing X11 grab which is not an ownerEvents grab, Xwayland would crash
trying to dereference the `NULL` sprite pointer:

  #0  __GI_raise ()
  #1  __GI_abort () at abort.c:79
  #2  OsAbort () at utils.c:1351
  #3  AbortServer () at log.c:879

  #9  xwl_pointer_warp_emulator_maybe_lock () at xwayland-input.c:2673
  #10 pointer_handle_enter () at xwayland-input.c:434

Avoid the crash by simply checking for the sprite being not `NULL` in
`xwl_pointer_warp_emulator_maybe_lock()`

655b1eb32e meson: Convert xquartz from autotools
Differences from autotools:

* Autotools defined NO_ALLOCA for OSX builds.  I don't think we need
this anymore as Xalloc.h is no longer used anywhere in the xserver.

* X11.bin is linked with -u,miDCInitialize, and then libserver_mi
provided to satisfy (just) that.  It's been that way since the commit
which added it.  We can't write the equivalent in meson due to linker
argument ordering issues, but do we really need to?

* An explicit -Dsecure-rpc=false is required for OSX, since in meson we
don't do the checks that XTRANS_SECURE_RPC_FLAGS did for the existence
of the specific RPC functions required.

8ab80fd505 xf86: set status to connected for monitors enabled in conf
If the user sets Option "Enable" "TRUE" for a monitor, the X
server will connect the connector a crtc but tell the user it

However the user in this case is mutter, when it gets it's view
of the output configuration it sees the output is disconnected
and never sets it up again, which seems like the right thing to do.

If we let the user enable a monitor, lets just set it as always

5a549c957a Revert "systemd-logind: Monitor systemd-logind going away"
systemd-logind since version 234 (released 2017-07-12) supports being
restarted without losing state [1]. From the systemd NEWS file [2]:

 * systemd-logind may now be restarted without losing state. It stores
   the file descriptors for devices it manages in the system manager
   using the FDSTORE= mechanism. Please note that further changes in
   other components may be required to make use of this (for example
   Xorg has code to listen for stops of systemd-logind and terminate
   itself when logind is stopped or restarted, in order to avoid using
   stale file descriptors for graphical devices, which is now
   counterproductive and must be reverted in order for restarts of
   systemd-logind to be safe. See
   https://cgit.freedesktop.org/xorg/xserver/commit/?id=dc48bd653c7e101.)

e51ebc18a7 xfree86/modes: Add "NoOutputInitialSize" option
Normally, the X server infers the initial screen size based on any
connected outputs.  However, if no outputs are connected, the X server
picks a default screen size of 1024 x 768.  This option overrides the
default screen size to use when no outputs are connected.  In contrast
to the "Virtual" Display SubSection entry, which applies unconditionally,
"NoOutputInitialSize" is only used if no outputs are detected when the
X server starts.

Parse this option in the new exported helper function
xf86AssignNoOutputInitialSize(), so that other XFree86 loadable drivers
can use it, even if they don't use xf86InitialConfiguration().

ff56048855 dri2: Stop pretending VGA arbitration matters
The VGA arbiter controls the PCI bus' routing of legacy VGA resources,
specifically the video memory aperture at 0xa0000-0xb0000 (640k should
be etc.) and a handful of I/O ports. Since 128k is far too small for a
real framebuffer these days, every driver instead maps a linear version
of VRAM through the PCI BAR. And no DRI2 drivers ever need I/O port
access, because all operations they might be used for (legacy VGA CRTC
setup, mostly) happen on the kernel side.

In other words, this just works, and we can stop breaking it.

e8295c5020 xwayland: handle case without any crtc
Xwayland creates and destroys the CRTC along with the Wayland outputs,
so there is possibly a case where the number of CRTC drops to 0.

However, `xwl_present_get_crtc()` always return `crtcs[0]` which is
invalid when `numCrtcs` is 0.

That leads to crash if a client queries the Present capabilities when
there is no CRTC, the backtrace looks like:

  #0  raise() from libc.so
  #1  abort() from libc.so
  #2  OsAbort() at utils.c:1350
  #3  AbortServer() at log.c:879
  #4  FatalError() at log.c:1017
  #5  OsSigHandler() at osinit.c:156
  #6  OsSigHandler() at osinit.c:110
  #7  <signal handler called>
  #8  main_arena() from libc.so
  #9  proc_present_query_capabilities() at present_request.c:236
  #10 Dispatch() at dispatch.c:478
  #11 dix_main() at main.c:276

To avoid returning an invalid pointer (`crtcs[0]`) in that case, simply
check for `numCrtcs` being 0 and return `NULL` in that case.

Thanks to Michel Dänzer <michel.daenzer@amd.com> for pointing this as a
possible cause of the crash.

899d260701 ci: Work around broken python UTF8 handling in the CI docker image
Gitlab very kindly exposes the details of the git commit message (among
much else) in the environment. Unfortunately, piglit tries to handle the
environment in non-UTF8-safe ways, which means if the top-of-tree commit
mentions non-ASCII characters (say, in the author's name) then all the
tests fail and so does the pipeline.

Fortunately none of those variables are things our piglit invocation
needs. Since I've failed to rebuild the docker image as yet, just clear
the likely variables from the environment before running piglit.

7a44e8d400 modesetting: Actually disable CRTCs in legacy mode
Believe it or not, somehow we've never done this in legacy mode! We
currently simply change the DPMS property on the CRTC's output's
respective DRM connector, but this means that we're just setting the
CRTC as inactive-not disabled. From the perspective of the kernel, this
means that any shared resources used by the CRTC are still in use.

This can cause problems for drivers that are not yet fully atomic,
despite using the atomic helpers internally. For instance: if CRTC-1 and
CRTC-2 are still enabled and use shared resources within the kernel (an
MST topology, for example), and then userspace tries to go enable CRTC-3
on the same topology this might suddenly fail if CRTC-3 needs the shared
resources CRTC-1 and CRTC-2 are using. While I don't know of any
situations in the mainline kernel that actually trigger this, future
plans for reworking the atomic check of MST drivers are absolutely
going to make this into a real issue (they already are in my WIP
branches for the kernel).

So: actually do the right thing here and disable CRTCs when they're not
going to be used anymore, even in legacy mode.

e6cd1c9bde xwayland: Don't take buffer release queue into account for frame timer
The buffer release queue has two kinds of entries:

* Pending async flips.
* Completed flips waiting for their buffer to be released by the Wayland
  compositor.

xwl_present_timer_callback neither completes async flips nor releases
buffers, so the timer isn't needed for the buffer release queue.

6b016d58d2 xwayland: Replace xwl_window::present_window with ::present_flipped
There's no need to keep track of the window which last performed a
Present flip. This fixes crashes due to the assertion in
xwl_present_flips_stop failing. Fixes issue #10.

The damage generated by a flip only needs to be ignored once, then
xwl_window::present_flipped can be cleared. This may fix freezing in
the (hypothetical) scenario where Present flips are performed on a
window, followed by other drawing requests using the window as the
destination, but nothing triggering xwl_present_flips_stop. The damage
from the latter drawing requests would continue being ignored.

ace551d8a2 xwayland: Complete "synchronous" Present flips from xwl_present_msc_bump
Completing them from xwl_present_sync_callback had at least two issues:

* It was before the MSC was incremented in xwl_present_frame_callback,
  so the MSC value in the completion event could be lower than the
  target specified by the client. This could cause hangs with the Mesa
  Vulkan drivers.
* It allowed clients to run at a frame-rate higher than the Wayland
  compositor's frame-rate, wasting energy on generating frames which
  were never displayed. This isn't expected to happen unless the client
  specified PresentOptionAsync (in which case flips are still completed
  from xwl_present_sync_callback, allowing higher frame-rates).

v2:
* Make xwl_present_has_events return true when there's a pending
  "synchronous" flip, so those complete after at most ~1 second even if
  the Wayland server doesn't send a frame event.

5e8b9a3a56 xwayland: Use xwl_present_reset_timer in xwl_present_timer_callback
Apart from simplifying the code, this should also prevent a condition
(which might only be possible with the following fix) reported in
https://gitlab.freedesktop.org/wayland/weston/issues/115#note_52467:

1. xwl_present_timer_callback indirectly calls xwl_present_reset_timer
   -> xwl_present_free_timer
2. xwl_present_timer_callback then returns a non-0 value, so DoTimer
   calls TimerSet with the old xwl_present_window->frame_timer pointer
   which was freed in step 1 => use after free

Calling xwl_present_reset_timer explicitly passes NULL to TimerSet if
step 1 freed xwl_present_window->frame_timer, and it will allocate a new
one.

036794bebc xwayland: do not crash if gbm_bo_create() fails
The function `xwl_glamor_gbm_create_pixmap()` first creates a buffer
objects and then creates the xwl_pixmap from it.

However, `xwl_glamor_gbm_create_pixmap_for_bo()` is not called if the
buffer object creation fails, and `xwl_glamor_gbm_create_pixmap()`
simply returns `glamor_create_pixmap()`.

The problem with this is that if `xwl_glamor_gbm_create_pixmap_for_bo()`
is not called then neither is `xwl_pixmap_set_private()` and further
calls to `xwl_pixmap_get()` will return NULL and cause a NULL pointer
dereference if the return value is not checked:

  #0  xwl_glamor_gbm_get_wl_buffer_for_pixmap ()

  #9  _start ()

  (gdb) print xwl_pixmap
  $1 = (struct xwl_pixmap *) 0x0

Make sure we check for `xwl_pixmap_get()` returned value where relevant
and fail gracefully if this is the case.

0816e8fca6 linux: Make platform device probe less fragile
At the point where xf86BusProbe runs we haven't yet taken our own VT,
which means we can't perform drm "master" operations on the device. This
is tragic, because we need master to fish the bus id string out of the
kernel, which we can only do after drmSetInterfaceVersion, which for
some reason stores that string on the device not the file handle and
thus needs master access.

Fortunately we know the format of the busid string, and it happens to
almost be the same as the ID_PATH variable from udev. Use that instead
and stop calling drmSetInterfaceVersion.

Mesa started supporting GL_OES_EGL_image on llvmpipe in 17.3, after this

        st/dri: add drisw image extension

That's pretty cool, but it means glamor now thinks it can initialize on
llvmpipe. This is almost certainly not what anyone wants, as glamor on
llvmpipe is pretty much uniformly slower than fb.

This fixes both Xorg and Xwayland to refuse glamor in such a setup.
Xephyr is left alone, both because glamor is not the default there and
because Xephyr+glamor+llvmpipe is one of the easier ways to get xts to
exercise glamor.

The (very small) downside of this change is that you lose DRI3 support.
This wouldn't have helped you very much (since an lp glamor blit is
slower than a pixman blit), but it would eliminate the PutImage overhead
for llvmpipe's glXSwapBuffers. A future change should add DRI3 support
for the fb-only case.

d791c8e5ab dga: Make shutdown less magical and/or terrifying
DGAShutdown() walks every screen and attempts to reset the mode.  That's
maybe a reasonable thing to do, although the explicit loop is certainly
a bad smell.

In ddxGiveUp it's called after we've torn down the vga arbiter - and in
fact most of the rest of screen state - which is... very very bad.  The
other place it's called is from the Control-Alt-BackSpace handler, where
we don't even attempt to do vga arb setup, and where in any case we're
going to escape the main loop eventually anyway.

Move all that cleanup work inside DGACloseScreen. This means it happens
earlier in server teardown than previously, but not in a way you're ever
going to be upset about.

3f31f56929 xwayland: Remove xwl_present_window from privates on cleanup
Xwayland's `xwl_destroy_window()` invokes `xwl_present_cleanup()`

But then `DestroyWindow()` calls `present_destroy_window()` which will
possibly end up in `xwl_present_abort_vblank()` which will try to access
data that was previously freed by `xwl_present_cleanup()`:

This is because `xwl_present_cleanup()` frees the memory but does not
remove it from the window's privates, and `xwl_present_abort_vblank()`
will still find it and hence try to access that freed memory...

Remove `xwl_present_window` from window's privates on cleanup so that no
other function can find and reuse that data once it's freed.

cd285922cd xwayland: use wayland axis_discrete event
This prevents multiple scroll events happening for wayland compositors
which send axis values other than 10. For example, libinput will
typically return 15 for each scroll wheel step, and if a wayland
compositor sends those to xwayland without normalising them, 2 scroll
wheel steps will end up as 3 xorg scroll events. By listening for the
discrete_axis event, this will now correctly send only 2 xorg scroll
events.

The wayland protocol gurantees that there will always be an axis event
following an axis_discrete event. However, it does not gurantee that
other events (including other axis_discrete+axis pairs) will not happen
in between them. So we must keep a list of outstanding axis_discrete
events.

f79e536851 modesetting: code refactor for PRIME sync
The X will be crashed on the system with other DDX driver,
such as amdgpu.

(EE)

The issue is that modesetting as the master, and amdgpu as the slave.
Thus, when the master attempts to access pSlavePixPriv in ms_dirty_update(),
problems result due to the fact that it's accessing AMD's 'ppriv' using the
modesetting structure definition.

Apart from fixing crash issue, the patch fix other issue in master interface
in which driver should refer to master pixmap.

1ef7aed3e2 During reset/shutdown, clean up leases in DIX instead of each driver
Instead of having every video driver loop over any pending leases to
free them during CloseScreen, do this up in the DIX layer by
terminating leases when a leased CRTC or Output is destroyed and
(just to make sure), also terminating leases in RRCloseScreen. The
latter should "never" get invoked as any lease should be associated
with a resource which was destroyed.

This is required as by the time the driver's CloseScreen function is
invoked, we've already freed all of the DIX randr structures and no
longer have any way to reference the leases

186a21c4ba glamor: Unbreak glamor_fd_from_pixmap()
When support for allocating GBM BOs with modifiers was added,
glamor_fd_from_pixmap() was changed so that it would return an error if
it got a bo with modifiers set from glamor_fds_from_pixmap(). The
problem is that on systems that support BOs with modifiers,
glamor_fds_from_pixmap() will always return BOs with modifiers.

This means that glamor_fd_from_pixmap() was broken entirely, which broke
a number of other things including glamor_shareable_fd_from_pixmap(),
which meant that modesetting using multiple GPUs with the modesetting
DDX was also broken. Easy reproducer:

- Find a laptop with DRI prime that has outputs connected to the
  dedicated GPU and integrated GPU
- Try to enable one display on each using the modesetting DDX
- Fail

Since there isn't a way to ask for no modifiers from
glamor_fds_from_pixmap, we create a shared _glamor_fds_from_pixmap()
function used by both glamor_fds_from_pixmap() and
glamor_fd_from_pixmap() that calls down to the appropriate
glamor_egl_fd*_from_pixmap() function.

c12f1bd4b7 modesetting: Also disable CRTC in drmmode_output_disable()
So, this did actually work on older kernels at one point in time,
however it seems that this working was a result of some of the Linux
kernel's atomic modesetting helpers not preserving the CRTC's enabled
state in the right spots. This was fixed in:

846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2")

As a result, atomic commits which simply disassociate a DRM connector
with it's CRTC while leaving the CRTC in an enabled state aren't enough
to disable the CRTC, and result in the atomic commit failing. This
currently can cause issues with MST hotplugging where X will end up
failing to disable the MST outputs after they've left the system. A
simple reproducer:

- Start up Xorg
- Connect an MST hub with displays connected to it
- Remove the hub
- Now there should be CRTCs stuck on the orphaned MST connectors, and X
  won't be able to reclaim them.

792359057b xwayland: simplify xwl_glamor_pixmap_get_wl_buffer()
When retrieving the Wayland buffer from a pixmap, if the buffer already
exists, the GBM backend will return that existing buffer.

However, as seen with the Present issues, if the call had previously
passed a wrong size, that buffer will remain at the wrong size for as
long as the buffer exists, which is error prone.

Considering that the width/height passed to get_wl_buffer() is always the
actual pixmap  drawable size, and considering that the EGLStream backend
makes no use of the size either, there is really no point in passing the
width/height around.

Simplify the xwl_glamor_pixmap_get_wl_buffer() and EGL backends API by
removing the pixmap size, and use the drawable size instead.

d7185a84b6 xwayland: refactor EGL backends for wayland registry
To be able to check for availability of the Wayland interfaces required
to run a given EGL backend (either GBM or EGLStream for now), we need
to have each backend structures and vfuncs in place before we enter the
Wayland registry dance.

That basically means that we should init all backends at first, connect
to the Wayland compositor and query the available interfaces and then
decide which backend is available and should be used (or none if either
the Wayland interfaces or the EGL extensions are not available).

For this purpose, hold an egl_backend struct for each backend we are to
consider prior to connect to the Wayland display so that, when we get to
query the Wayland interfaces, everything is in place for each backend to
handle the various Wayland interfaces.

Eventually, when we need to chose which EGL backend to use for glamor,
the available Wayland interfaces and EGL extensions available are all
known to Xwayland.

This can happen when the client changes its size (e.g. switching to

and causes continuous flickering.

Use the actual pixmap's drawable size instead of the present box to
create the buffer so that it's sized appropriately.

and old drmWaitVblank ioctl, implement new wraparound handling, which
also allows to deal with wraparound in the other direction, e.g., if a
32-Bit truncated sequence value is passed in, whose true 64-Bit
in-kernel hw value is within 2^30 counts of the previous processed
value, but whose 32-bit truncated sequence value happens to lie just
above or below a 2^32 boundary, iow. one of the two values 'sequence'
vs. 'msc_prev' lies above a 2^32 border, the other one below it.

The method is directly translated from Mesa's proven implementation of
the INTEL_swap_events extension, where a true underlying 64-Bit wide
swapbuffers count (SBC) needs to get reconstructed from a 32-Bit LSB
truncated SBC transported over the X11 protocol wire. Same conditions
apply, ie. successive true 64-Bit SBC values are close to each other,
but don't always get received in strictly monotonically increasing
order. See Mesa commit cc5ddd584d17abd422ae4d8e83805969485740d9 ("glx:
Handle out-of-sequence swap completion events correctly. (v2)") for
explanation.

Additionally add a separate path for true 64-bit msc input originating
from Linux 4.15+ drmCrtcGetSequence/QueueSequence ioctl's and
corresponding 64-bit vblank events. True 64-bit msc's don't need
remapping and must be passed through.

As a reliability bonus, they are also used here to update the tracking
values msc_prev and ms_high with perfect 64-Bit ground truth as baseline
for mapping msc from pageflip completion events, because pageflip events
are always 32-bit wide, even when the new kernel api's are used. Because
each pageflip(-event) is always preceeded close in time (and vblank
count) by a drmCrtcQueueSequence queued event or drmCrtcGetSequence
query as part of DRI2 or DRI3+Present swap scheduling, we can be certain
that each pageflip event will get its truncated 32-bit msc remapped
reliably to the true 64-bit msc of flip completion whenever the sequence
api is available, ie. on Linux 4.15 or later.

Note: In principle at least the 32-bit mapping path could also be
backported to earlier server branches, as this seems to be broken for at
least server 1.16 to 1.19.

73f0ed2d92 modesetting: Remove ms_crtc_msc_to_kernel_msc().
The function is ported from intel-ddx uxa backend around 2013, where its
stated purpose was to apply a vblank_offset to msc values to correct for
problems with those kernel provided msc values. Some (somewhat magic and
puzzling to myself) heuristic tried to guess if provided values were
unreasonable and tried to adapt the corrective vblank_offset to account
for that.

Except: It wasn't applied to kernel provided msc values, but the values
delivered by clients via DRI2 or Present, so valid client targetmsc
values, e.g., requesting a vblank event > 1000 vblanks in the future,
triggered the offset correction in arbitrarily wrong ways, leading to
wrong msc values being returned and thereby vblank events queued to the
kernel for the wrong time. This causes glXSwapBuffersMscOML and
glXWaitForMscOML to swap / return immediately whenever a swap/wait in >
1000 vblanks is requested.

The original code was also written to only deal with 32 bit mscs, but
server 1.20 modesetting ddx can now use new Linux 4.15+ kernel vblank
api to process true 64 bit msc's, which may confuse the heuristic even
more due to 32 bit integer truncation/wrapping.

This code caused various problems in the intel-ddx in the past since
year 2013, and was removed there in 2015 by Chris Wilson in commit
42ebe2ef9646be5c4586868cf332b4cd79bb4618:

"    uxa: Remove the filtering of bogus Present MSC values

    If the intention was to filter the return values from the kernel, the
    filtering would have been applied to the kernel values and not to the
    incoming values from Present. This filtering introduces crazy integer
    promotion and truncation bugs all because Present feeds garbage into its
    vblank requests.

"

Indeed, i found a Mesa bug yesterday which can cause Mesa's
PresentPixmap request to spuriously feed garbage targetMSC's into the
driver under some conditions. However, while other video drivers seem to
cope relatively well with that, modesetting ddx causes KDE-5's
plasmashell to lock up badly quite frequently, and my suspicion is that
the code removed in this commit is one major source of the extra
fragility.

Also my own tests fail for any swap scheduled more than 1000 vblanks
into the future, which is not uncommon for some scientific applications.

Iow. modesetting's swap scheduling seems to be more robust without this
function afaics.

54ac09717c xwayland: Add glamor egl_backend for EGLStreams
This adds initial support for displaying Xwayland applications through
the use of EGLStreams and nvidia's custom wayland protocol by adding
another egl_backend driver. This also adds some additional egl_backend
hooks that are required to make things work properly.

EGLStreams work a lot differently then the traditional way of handling
buffers with wayland. Unfortunately, there are also a LOT of various
pitfalls baked into it's design that need to be explained.

This has a very large and unfortunate implication: direct rendering is,
for the time being at least, impossible to do through EGLStreams. The
main reason being that the EGLStream spec mandates that we lose the
entire color buffer contents with each eglSwapBuffers(), which goes
against X's requirement of not losing data with pixmaps.  no way to use
an allocated EGLSurface as the storage for glamor rendering like we do
with GBM, we have to rely on blitting each pixmap to it's respective
EGLSurface producer each frame. In order to pull this off, we add two
different additional egl_backend hooks that GBM opts out of
implementing:

- egl_backend.allow_commits for holding off displaying any EGLStream
  backed pixmaps until the point where it's stream is completely
  initialized and ready for use
- egl_backend.post_damage for blitting the content of the EGLStream
  surface producer before Xwayland actually damages and commits the
  wl_surface to the screen.

The other big pitfall here is that using nvidia's wayland-eglstreams
helper library is also not possible for the most part. All of it's API
for creating and destroying streams rely on being able to perform a
roundtrip in order to bring each stream to completion since the wayland
compositor must perform it's job of connecting a consumer to each
EGLstream. Because Xwayland has to potentially handle both responding to
the wayland compositor and it's own X clients, the situation of the
wayland compositor being one of our X clients must be considered. If we
perform a roundtrip with the Wayland compositor, it's possible that the
wayland compositor might currently be connected to us as an X client and
thus hang while both Xwayland and the wayland compositor await responses
from eachother. To avoid this, we work directly with the wayland
protocol and use wl_display_sync() events along with release() events to
set up and destroy EGLStreams asynchronously alongside handling X
clients.

Additionally, since setting up EGLStreams is not an atomic operation we
have to take into consideration the fact that an EGLStream can
potentially be created in response to a window resize, then immediately
deleted due to another pending window resize in the same X client's
pending reqests before Xwayland hits the part of it's event loop where
we read from the wayland compositor. To make this even more painful, we
also have to take into consideration that since EGLStreams are not
atomic that it's possible we could delete wayland resources for an
EGLStream before the compositor even finishes using them and thus run
into errors. So, we use quite a bit of tracking logic to keep EGLStream
objects alive until we know the compositor isn't using them (even if
this means the stream outlives the pixmap it backed).

While the default backend for glamor remains GBM, this patch exists for
users who have had to deal with the reprecussion of their GPU
manufacturers ignoring the advice of upstream and the standardization of
GBM across most major GPU manufacturers. It is not intended to be a
final solution to the GBM debate, but merely a baindaid so our users
don't have to suffer from the consequences of companies avoiding working
upstream. New drivers are strongly encouraged not to use this as a
backend, and use GBM like everyone else. We even spit this out as an
error from Xwayland when using the eglstream backend.

e29d783278 modesetting: Only use modifiers on kms drivers which do support them.
Use the DRM_CAP_ADDFB2_MODIFIERS query to make sure the kms
driver supports modifiers in the addfb2 ioctl, and fall back
to addfb ioctl without modifiers if modifiers are unsupported.

E.g., as of Linux 4.17, nouveau-kms so far does not suppport
modifiers and gets angry if drmModeAddFB2WithModifiers() is
called (-> failure to set a video mode -> blank screen), but
Mesa's nvc0+ gallium driver causes gbm_bo_get_modifier() to
return a valid modifier by translating the default tiling of
bo's created via gbm_bo_create() into a modifier other than
DRM_FORMAT_MOD_INVALID (see Mesa's nvc0_miptree_get_modifier()).

Testing for != DRM_FORMAT_MOD_INVALID is apparently not
sufficient for safe use of drmModeAddFB2WithModifiers.

Bonus: Handle potential failure of populate_format_modifiers().

The required DRM_CAP is defined since libdrm v2.4.65, and we
require v2.4.89+ for the server, so we can use it unconditionally.

Tested on intel-kms, radeon-kms, nouveau-kms. Fixes failure on
NVidia Pascal.

ce2a4313dd modesetting: Fix page flipping harder under DRI 3.2.
Non-atomic kms drivers like radeon-kms (or nouveau-kms with
default setting of "atomic ioctl disabled") don't export
any formats, so num_formats == 0.

Some atomic drivers (nouveau-kms with boot param nouveau.atomic=1,
or intel-kms on, e.g., Linux 4.13) expose num_formats == 0, or
don't expose any modifiers, so num_modifiers == 0.

Let the drmmode_is_format_supported() check pass in these cases
to allow page flipping, as it works just fine.

Tested on NV-96 for nouveau, HD-5770 for radeon, Intel Ivybridge
with Linux 4.13 and drm-next to fix page flipping.

Now, that string gets run together with the version:

0fb2cca193 xwayland: Preliminary support for Present's new window flip mode
Introduce support for Present's window flip mode. The support is not yet
complete, but works reasonable well for the most important use case, that
is fullscreen applications.

We take a Present flip and if the xwl_window->window has the same dimensions
as the presenting window, the flip is represented by a wl_buffer and attached
to the main wl_surface of the xwl_window.

After commit we are listening for the sync callback in order to tell Present,
that the pixmap flip is not longer pending, for the frame callback in order
to update the msc counter and for the buffer release callback in order to tell
Present that the pixmap is idle again.

The following functionality is missing from this patch:
* (slowed down) flips in case the compositor is not sending frame callbacks,
* queuing events to MSC times,
* per window flips for child windows with smaller size than the xwl_window.

To make use of this functionality Xwayland must run rootless and with
Glamor/GBM.

e4e3447603 Add RandR leases with modesetting driver support [v6]
This adds support for RandR CRTC/Output leases through the modesetting
driver, creating a lease using new kernel infrastructure and returning
that to a client through an fd which will have access to only those
resources.

v2:	Restore CRTC mode when leases terminate

	When a lease terminates for a crtc we have saved data for, go
	ahead and restore the saved mode.

v3:	Report RR_Rotate_0 rotations for leased crtcs.

	Ignore leased CRTCs when selecting screen size.

	Stop leasing encoders, the kernel doesn't do that anymore.

	Turn off crtc->enabled while leased so that modesetting
	ignores them.

	Check lease status before calling any driver mode functions

	When starting a lease, mark leased CRTCs as disabled and hide
	their cursors. Also, check to see if there are other
	non-leased CRTCs which are driving leased Outputs and mark
	them as disabled as well. Sometimes an application will lease
	an idle crtc instead of the one already associated with the
	leased output.

	When terminating a lease, reset any CRTCs which are driving
	outputs that are no longer leased so that they start working
	again.

	This required splitting the DIX level lease termination code
	into two pieces, one to remove the lease from the system
	(RRLeaseTerminated) and a new function that frees the lease
	data structure (RRLeaseFree).

v4:	Report RR_Rotate_0 rotation for leased crtcs.

v5: Terminate all leases on server reset.

	Leases hang around after the associated client exits so that
	the client doesn't need to occupy an X server client slot and
	consume a file descriptor once it has gotten the output
	resources necessary.

	Any leases still hanging around when the X server resets or
	shuts down need to be cleaned up by calling the kernel to
	terminate the lease and freeing any DIX structures.

	Note that we cannot simply use the existing
	drmmode_terminate_lease function on each lease as that wants
	to also reset the video mode, and during server shut down that

   modesetting: Validate leases on VT enter

	The kernel doesn't allow any master ioctls to run when another
	VT is active, including simple things like listing the active
	leases. To deal with that, we check the list of leases
	whenever the X server VT is activated.

   xfree86: hide disabled cursors when resetting after lease termination

	The lessee may well have played with cursors and left one
	active on our screen. Just tell the kernel to turn it off.

v6:	Add meson build infrastructure

At screen depths > 24 bit, the color palettes passed into

than the crtc's hardware lut. E.g., at depth 30, 1024 palette
slots vs. 256 hw lut slots. This palette size > crtc gamma size
case is not handled yet and leads to silent failure, so gamma
table updates do not happen.

Add a new subsampling path for this case.

This makes lut updates work again, as tested with the xgamma
utility (uses XF86VidMode extension) and some RandR based
gamma ramp animation.

v2: Better resampling when subsampling the palette, as
    proposed by Ville. Now reaches the max index of the
    palette and deals with non-power-of-two sizes. Thanks.

efe9e3e9ff modesetting: Fix fallback for lack of new vblank kernel API.
Turns out that the kernel DRM ioctl handling returns EINVAL
instead of ENOTTY if one tries to call the new drmCrtcGetSequence()
or drmCrtcQueueSequence() ioctl's introduced in Linux 4.15 on an
older kernel where they are missing. This causes the fallback code
not to fall back to the old drmWaitVblank() ioctl and thereby
failure of vblank stuff.

E.g., on Linux 4.13, glxgears -info runs unthrottled at 10000 fps
instead of 60 fps. Also breakage of OML_sync_control extension.

Check for errno != EINVAL before setting has_queue_sequence = TRUE.

Additionally in case of supported drmCrtcQueueSequence(), set
has_queue_sequence = TRUE on success, or we might get at
least a temporary failure in ms_queue_vblank().

One slight ambiguity is that we can also get EINVAL if
drm_crtc_vblank_get() fails in the kernel, so if that
happened at first invocation of the new api, we'd fall
back to drmWaitVblank() and then fail there, instead of
failing in the new api, but the end result would be the
same.

d8ec33fe05 glx: Use vnd layer for dispatch (v4)
The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.

Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.

v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

backend. (Kyle Brenneman)

This appears to be the result of xwl_cursor_confined_to() and
xwl_screen_get_default_seat(). While not against protocol, mutter ends
up sending xdg_output before wl_seat. xwl_screen_get_default_seat()
makes the naïve assumption that we always have a valid seat, we end up
returning a pointer to the empty list itself instead of an actual seat
and causing ourselves to segfault.

So, actually return NULL in xwl_screen_get_default_seat() if the seat
list is empty, and skip any pointer confinement processing in
xwl_cursor_confined_to() when we don't have a seat setup yet.

dd00e5466a xfree86: Remove broken RANDR disabling logic (v4)
The only way to get at xf86Info.disableRandR from configuration is
Option "RANDR" "foo" in ServerFlags, which probably nobody is using
seeing as it's not documented. The other way it could be set is if a
screen supports RANDR 1.2, in which case we set it to avoid trying to
use the RANDR 1.1 compat code. If the second screen is not 1.2-aware
then this would mean we don't do RANDR setup on the second screen at
all, which would almost certainly crash the first time you try to do
RANDR operations on the second screen.

Fix that all by deletion, and just check whether the screen already has
RANDR initialized before installing the stub support. If you want to
disable RANDR, use the Extensions section of xorg.conf instead.

v2: Also remove a now entirely pointless log message, telling you to

3362422e84 xwayland: remove dirty window unconditionally on unrealize
This is a rare occurrence of a crash in Xwayland for which I don't have
the reproducing steps, just a core file.

The backtrace looks as follow:

  #0  raise () from /usr/lib64/libc.so.6
  #1  abort () from /usr/lib64/libc.so.6
  #2  OsAbort () at utils.c:1361
  #3  AbortServer () at log.c:877
  #4  FatalError () at log.c:1015

  #11 WaitForSomething () at WaitFor.c:219
  #12 Dispatch () at dispatch.c:422
  #13 dix_main () at main.c:287

The crash is caused by dereferencing “xwl_pixmap->buffer” in
xwl_glamor_pixmap_get_wl_buffer() because “xwl_pixmap” is NULL.

Reason for this is because the corresponding pixmap is from the root
window and xwayland is rootless by default.

This can happen if the window was mapped, redirected, damaged and
unredirected immediately, before the damage is processed by Xwayland.

Make sure to remove the dirty window from the damage list on unrealize
to prevent this from happening.

Credit goes to Adam Jackson <ajax@nwnk.net> and Daniel Stone
<daniel@fooishbar.org> for finding the root cause the issue.

da8de2a7f6 xwayland: Add optional xdg-output support
The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.

For now it just features the position and logical size which describe
the output position and size in the global compositor space.

This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).

This was added in wayland-protocols 1.10.

f72587ecc7 xwayland: reduce over-damage
If an X11 app draws a little here, some there, and a tiny bit in the
opposite corner, using RegionExtents for the damage to be sent to the
Wayland compositor will cause massive over-damaging.

However, we cannot blindly send an arbitrary number of damage
rectangles, because there is a risk of overflowing the Wayland
connection. If that happens, it triggers an abort in libwayland-client.

Try to be more accurate with the damage by sending up to 256 rectangles
per window, and fall back to extents otherwise. The number is completely
arbitrary.

f615cb62d4 Xorg.wrap: Ensure correct ordering of post-install hook
The install rule of Xorg.wrap is currently a dependency of the
install-data target instead of the install-exec target. The build also
uses install-exec-hook to change the ownership and set the SUID bit on
the Xorg.wrap binary. The problem is that install-exec-hook is only
ordered respective to the install-exec target, the rules of install-data
may or may not have been executed.

If install-exec-hook runs before the Xorg.wrap binary is in place,
a message similar to the following will be present in the build log:

chown: cannot access '/pkgdir/usr/lib/xorg-server/Xorg.wrap': No such file or directory
make[6]: [Makefile:1151: install-exec-hook] Error 1 (ignored)

All that needs to be done is to change the name of the program variable
to contain 'exec' for the install rule to depend on the install-exec
target.

Excerpt from the Automake manual, chapter 12.2 The Two Parts of Install:
"Any variable using a user-defined directory prefix with ‘exec’ in the
name (e.g., myexecbin_PROGRAMS) is installed by install-exec. All other
user-defined prefixes are installed by install-data."

should not use), and there all it serves to do is make signals generated
by the vm86 task non-fatal. In practice this error appears never to
happen, and marching ahead with root privileges after arbitrary code has
raised a signal seems like a poor plan.

Remove the usage in the vm86 code, making this error fatal.

722c8035dc xfree86: Remove xf86InterceptSigIll
This was added in ~2004 for the sis driver, to detect whether it could
use SSE for memcpy. Charmingly, the code to check whether that feature
exists in the server is:

    #if XORG_VERSION_CURRENT >= XORG_VERSION_NUMERIC(6,8,99,13,0)
    #define SISCHECKOSSSE           /* Automatic check OS for SSE; requires SigIll facility */
    #endif

Which means it has never worked in any modular server release.

A less gross way to do this is to check for SSE support with getauxval()
or /proc/cpuinfo or similar. Since no driver is using the existing
intercept mechanism, drop it.

fe46cbea0f xwayland: Give up “cleanly“ on Wayland socket errors
Xwayland is a pretty standard Wayland client, we want to be able to
capture core dumps on crashes.

Yet using "-core" causes any FatalError() to generate a core dump,
meaning that we would get a core file for all Wayland server crashes,
which would generate a lot of false positives.

Instead of using FatalError() on Wayland socket errors, give up cleanly
to avoid dumping core files when "-core" is used.

60f4646ae1 xwayland: Keep separate variables for pointer and tablet foci
The tablet/stylus interfaces reused xwl_seat->focus_window, which
would leave a somewhat inconsistent state of that variable for
wl_pointer purposes (basically, everything) if the pointer happened
to lay on the same surface than the stylus while proximity_out
happens.

We just want the stylus xwl_window to correctly determine we have
stylus focus, and to correctly translate surface-local coordinates
to root coordinates, this can be done using a different variable.

5d667df6ea glx: Fix glXQueryContext for GLX_FBCONFIG_ID and GLX_RENDER_TYPE (v2)
Just never filled in, oops. Seems to have gone unnoticed because
normally glXQueryContext simply returns the values filled in by the
client library when the context was created. The only path by which you
normally get to a GLXQueryContext request is glXImportContext, and then
only if the context is already indirect.

However, that's a statement about Mesa's libGL (and anything else that
inherited that bit of the SGI SI more or less intact). Nothing prevents
a mischeivous client from issuing that request of a direct context, and
if they did we'd be in trouble because we never bothered to preserve the
associated fbconfig in the context state, so we'd crash looking up
GLX_VISUAL_ID_EXT. So let's fix that too.

266d9868ca xf86-video-modesetting: Fix ms_queue_vblank(flags = MS_QUEUE_RELATIVE)
Change 677c32bc refactored all usages of drmWaitVBlank() into a helper function,
ms_queue_vblank().

ms_queue_vblank() takes in an MS_QUEUE_RELATIVE flag to indicate that the
sequence number is relative rather than absolute, but still treats the actual
sequence number as absolute, passing it through ms_crtc_msc_to_kernel_msc()
unconditionally before calling drmWaitVBlank().

ms_crtc_msc_to_kernel_msc() works by subtracting a vblank offset from the
provided sequence number, which only makes sense for absolute sequence numbers.
In the case of PRIME Sync, drmmode_SharedPixmapPrsentOnVBlank() passes in 1,
which results in a large negative vblank offset. After subtracting, we're left
with a relative sequence number of 100,000+, i.e. wait for 100,000+ vblanks...

In the relative case we want to pass in the sequence number unmodified. Simply
add a check to do this.

68d95e759f ramdac: Check ScreenPriv != NULL in xf86ScreenSetCursor()
Similar to change cba5a10f, xf86ScreenSetCursor() would dereference ScreenPriv
without NULL checking it. If Option "SWCursor" is specified, ScreenPriv == NULL.

Without this fix, it is observed that setting Option "SWCursor" "on" on the
modesetting driver in a PRIME configuration will segfault the server.

It is important to return success rather than failure in the instance that
ScreenPriv == NULL and pCurs == NullCursor, because otherwise xf86SetCursor()
can fall into infinite recursion: xf86SetCursor(pCurs) calls
xf86ScreenSetCursor(pCurs), and if FALSE, calls xf86SetCursor(NullCursor). If
xf86ScreenSetCursor(NullCursor) returns FALSE, it calls
xf86SetCursor(NullCursor) again and this repeats forever.

4d53e30651 meson: Don't use '' in link_with, ever
String arguments as elements in the array passed to the link_with
argument in meson's executable() functions are not valid and will end up
causing the build file generation to file. This actually ended up
exposing a bug in meson that caused it not to report where in the
meson.build file it was failing:

https://github.com/mesonbuild/meson/pull/2527

The proper way to have a variable that can contain either an empty link
target or an actual link target is:

some_target = []
if some_cond
    some_target = static_library(...)
endif

This way if some_cond is False, some_target gets set to [], gets passed
to executable() in the link_with array, and then gets removed by array
flattening.

This also unbreaks Xwayland builds with -Dglx=false, the thing that
originally made me notice this.

fbd80b2c8e modesetting: Blacklist EVDI devices from PRIME sync
UDL (usb) devices are blacklisted because of they weird behaviour when
it comes to vblank events. As EVDI uses very similar model of handling
vblanks it should be treated similarly.

When doing a page flip, EVDI does not wait for real vblank, but
simulates it by adding constant delay. It also does not support
DRM_IOCTL_WAIT_VBLANK.

In contrast to UDL, EVDI uses platform devices, thus instead of 'usb' in
path they all have 'platform'.

It is possible to blacklist by 'platform', so without explicitly saying
'evdi', but it might be misleading when it comes to real reason for it.

82df2ce38c xwayland: Avoid repeatedly looping through window ancestor chain
Calling xwl_window_from_window means looping through the window ancestor
chain whenever it is called on a child window or on an automatically
redirected window.

Since these properties and the potential ancestor's xwl_window are constant
between window realization and unrealization, we can omit the looping by
always putting the respective xwl_window in the Window's private field on
its realization. If the Window doesn't feature an xwl_window on its own,
it's the xwl_window of its first ancestor with one.

1089d5d518 xwayland: add envvar XWAYLAND_NO_GLAMOR
Not all compositors allow for customizing the Xwayland command line,
gnome-shell/mutter for example have the command line and path to
Xwayland binary hardcoded, which makes it harder for users to disable
glamor acceleration in Xwayland (glamor being used by default).

Add an environment variable XWAYLAND_NO_GLAMOR to disable glamor support
in Xwayland.

5abaa50b29 meson: Move the BUILD_DATE/TIME setup to configure time.
By having it as a custom_target with build_always, every "ninja -C
build" would rebuild Xorg for the new date/time, even if the rest of
Xorg didn't change.

We could build the rest of Xorg into a static lib, and regenerate
date/time when the static lib changes and link that into a final Xorg,
but BUILD_DATE/TIME is such a dubious feature (compared to including a
git sha, which is easy with meson) it doesn't seem worth the build
time cost.

cdd0352ba0 xwayland: Fix a segfault with pointer locking
Xwayland would crash in some circumstances while trying to issue a
pointer locking when the cursor is hidden when there is no seat focus
window set.

The crash signature looks like:

 #0  zwp_pointer_constraints_v1_lock_pointer ()
 #1  xwl_pointer_warp_emulator_lock () at xwayland-input.c:2584
 #2  xwl_seat_maybe_lock_on_hidden_cursor () at xwayland-input.c:2756
 #3  xwl_seat_maybe_lock_on_hidden_cursor () at xwayland-input.c:2765
 #4  xwl_seat_cursor_visibility_changed () at xwayland-input.c:2768
 #5  xwl_set_cursor () at xwayland-cursor.c:245
 #6  miPointerUpdateSprite () at mipointer.c:468
 #7  miPointerDisplayCursor () at mipointer.c:206
 #8  CursorDisplayCursor () at cursor.c:150
 #9  AnimCurDisplayCursor () at animcur.c:220
 #10 ChangeToCursor () at events.c:936
 #11 ActivatePointerGrab () at events.c:1542
 #12 GrabDevice () at events.c:5120
 #13 ProcGrabPointer () at events.c:4908
 #14 Dispatch () at dispatch.c:478
 #15 dix_main () at main.c:276

xwl_pointer_warp_emulator_lock() tries to use the surface from the
xwl_seat->focus_window leading to a NULL pointer dereference when that
value is NULL.

Check that xwl_seat->focus_window is not NULL earlier in the stack in
xwl_seat_maybe_lock_on_hidden_cursor() and return early if not the case
to avoid the crash.

ca17f3e9fd xwayland: Lock the pointer if it is confined and has no cursor
In the typical pattern in games of "hide cursor, grab with a confineTo,
warp constantly the pointer to the middle of the window" the last warping
step is actually rather optional. Some games may choose to just set up a
grab with confineTo argument, and trust that they'll get correct relative
X/Y axis values despite the hidden cursor hitting the confinement window
edge.

To cater for these cases, lock the pointer whenever there is a pointer
confinement and the cursor is hidden. This ensures the pointer position
is in sync with the compositor's when it's next shown again, and more
importantly resorts to the relative pointer for event delivery.

513e3bd387 xwayland: Update root window size when desktop size changes
This fixes grabs on InputOnly windows whose parent is the root window
failing with GrabNotViewable. This is due to window->borderSize/windowSize
being computed as clipped by its parent, resulting in a null region.

Setting up the right size on the root window makes the InputOnly size
correct too, so the GrabNotViewable paths aren't hit anymore.

4f29366f1e xwayland: Don't load extension list more than once
When running an Xwayland server from the command line, we end up
resetting the server every time all of the clients connected to the
server leave. This would be fine, except that xwayland makes the mistake
of unconditionally calling LoadExtensionList(). This causes us to setup
the glxExtension twice in a row which means that when we lose our last
client on the second server generation, we end up trying to call the glx
destructors twice in a row resulting in a segfault:

2fbf62b2fb xfree86: Fix interpretation of xf86WaitForInput timeout
Commit aa6717ce2 switched xf86WaitForInput from using select(2) to using
poll(2). Before this change, the timeout was interpreted as being in
microseconds; afterwards it is fed directly to xorg_poll which interprets
it as being in milliseconds. This results in the function potentially
blocking 1000x longer than intended. This commit scales down the timeout
argument before passing it to xorg_poll, being careful to ensure the result
is not rounded down due to integer division.

Hooked up a bit differently to the other tools. Those tools can be static for
all and be re-used. The wacom driver initializes the pad with the correct
number of buttons though and we can't do this until we have the pad done event.

If the tablet is removed and we plug a different one in, we should initialize
that correctly, so unlike the other tools the pad is properly removed and
re-initialized on plug.

f471b5b8eb xwayland: update cursor on tablet tools in proximity
Each xwl_tablet_tool gets a xwl_cursor, as on wayland each of those
will get an independent cursor that can be set through
zwp_tablet_tool.set_cursor.

However, all tools (and the pointer) share conceptually the same VCP
on Xwayland, so have cursor changes trigger a xwl_cursor update on
every tool (and the pointer, again). Maybe Xwayland could keep track
of the most recent device and only update that cursor to get better
visual results, but this is simpler, and it's going to be odd
anyway...

5812d1c28f xwayland: Handle wp_tablet events
Creates and maintains the canonical trio of X devices (stylus, eraser,
and cursor) to be shared by all connected tablets. A per-tablet trio
could be created instead, but there are very few benefits to such a
configuration since all tablets still ultimately share control of a
single master pointer.

The three X devices are modeled after those created by xf86-input-wacom
but use a generic maximum X and Y that should be large enough to
accurately represent values from even the largest currently-available
tablets.
