Roman Gilg a69f7fbb54 xwayland: Recurse on finding the none-wm owner
An X11 window manager might add a chain of parent windows when reparenting to a
decoration window.

That is for example the case for KWin, which reparents client windows to one
decoration and another wrapper parent window.

Account for that by a recursion into the tree. For now assume as before that
all X11 window managers reparent with one child only for these parent windows.

Changes by Hans de Goede:
- Move the xwl_window_is_toplevel() from a later patch in this series here
  as it really belongs together with these changes
- Drop no longer necessary xwl_window argument from window_get_none_wm_owner
  parameters

Hans de Goede ded89300c1 xwayland: Cache client-id for the window-manager client
Instead of iterating over all clients which are listening for events on the
root window and checking if the client we are dealing with is the one
listening for SubstructureRedirectMask | ResizeRedirectMask events and thus
is the window-manager, cache the client-id of the window-manager in
xwl_screen and use that when checking if a client is the window-manager.

Note that we cache and compare the client-id rather then the ClienPtr,
this saves reading the ClientPtr from the global clients array when doing
the comparison.

Zoltán Böszörményi 42aaf37241 Fix modesetting device matching through kmsdev device path
xf86platformProbeDev didn't check the device path, fix it.

This is a problem when trying to set up a non-PCI device via
explicit xorg.conf.d configuration.

An USB DisplayLink device, being non-PCI was always set up
as a GPU device assigned to screen 0 instead of a regular
framebuffer, potentially having its own dedicated screen,
despite such configuration as below. Only the relevant parts
of the configuration are quoted, it's part of a larger context
with an Intel chip that has 3 outputs:
* DP1 connected to an LCD panel,
* VGA1 connected to an external monitor,
* HDMI1 unconnected and having no user visible connector

On the particular machine I was trying to set up an UDL device,
I found the following structure was being used to match
the device to a platform device while I was debugging the issue:

xf86_platform_devices[0] == Intel, /dev/dri/card1, primary platform device
xf86_platform_devices[1] == UDL, /dev/dri/card0

devList[0] == "Intel0", ZaphodHeads: DP1
devList[1] == "Intel1", ZaphodHeads: VGA1
devList[2] == "UDL"
devList[3] == "Intel2", ZaphodHeads: HDMI1 (intended GPU device to UDL)

When xf86platformProbeDev() matched the UDL device, the BusID
check failed in both cases of:
* BusID "usb:0:1.2:1.0" was specified
* Option "kmsdev" "/dev/dri/card0" was specified

As a result, xf86platformProbeDev() went on to call probeSingleDevice()
with xf86_platform_devices[0] and devList[2], resulting in the
UDL device being set up as a GPU device assigned to the first screen
instead of as a framebuffer on the third screen as the configuration
specified.

Checking Option "kmsdev" in code code may be a layering violation.
But the modesetting driver is actually part of the Xorg sources
instead of being an external driver, so he "kmsdev" path knowledge
may be used here.

This can happen, for example, if the server is configured with Xinerama
and there is more than one X screen:

 Section "ServerLayout"
   Identifier "crash"
   Screen 0 "modesetting"
   Screen 1 "dummy" RightOf "modesetting"
   Option "Xinerama"
 EndSection

 Section "Device"
   Identifier "modesetting"
   Driver "modesetting"
 EndSection

 Section "Screen"
   Identifier "modesetting"
   Device "modesetting"
 EndSection

 Section "Device"
   Identifier "dummy"
   Driver "dummy"
 EndSection

 Section "Screen"
   Identifier "dummy"
   Device "dummy"
 EndSection

The problem does not reproduce if there is only one X screen because of
this code in xf86RandR12Init:

 #ifdef PANORAMIX
     /* XXX disable RandR when using Xinerama */
     if (!noPanoramiXExtension) {
         if (xf86NumScreens == 1)
             noPanoramiXExtension = TRUE;
         else
             return TRUE;
     }
 #endif

Fix the problem by checking dixPrivateKeyRegistered(rrPrivKey) before
calling rrGetScrPriv. This is similar to what the xf86-video-amdgpu
driver does:

Alex Goins 456dff1bf8 modesetting: Fix msSharePixmapBacking Segfault Regression
Commit cb1b1e184 modified msSharePixmapBacking() to derive modesettingPtr from
the 'screen' argument. Unfortunately, the name of the argument is misleading --
the screen is the slave screen. If the master is modesetting,
and the slave is not modesetting, it will segfault.

To fix the problem, this change derives modesettingPtr from
ppix->drawable.pScreen. This method is already used when calling
ms->glamor.shareable_fd_from_pixmap() later in the function.

To avoid future issues, this change also renames the 'screen' argument to
'slave'.

Currently, `xwayland.h` contains all the declarations, which is a bit
awkward and hard to follow.

Move the Xwayland structures declarations to their own header file.

Michel Dänzer 846e81ecb8 xwayland: Create duplicate TrueColor GLXFBConfigs for Composite
Similar to what is done in Xorg. Not doing this prevented apps from
using GLX with a Composite visual, e.g. Firefox WebRender or Chromium.

v2:
* Fix inverted direct_color test, fixes Chromium as well.
* Drop Composite extension guards, since other Xwayland code calls
  compRedirectWindow/compUnredirectWindow unconditionally anyway.

Olivier Fourdan 46e5236bbe xwayland: Take border width into account
Damage coordinates are relative to the drawable, (0,0) being the top
left corner inside the border.

Therefore, when applying damages or accumulating damages between window
buffers, we need to take the window border width into account as well,
otherwise the updates might be only partial or misplaced.

Olivier Fourdan 1cb886bc2a xwayland: Recycle window buffers when setting pixmap
Right now, we would recycle the window buffers whenever the window the
window is resized.

This, however, is not sufficient to guarantee that the buffers are up
to date, since changing the window border width for example would not
trigger a `WindowResize` (the border being outside the window).

Make sure we recycle the buffers on `SetWindowPixmap` to ensure that
the buffers will be recycled whenever the pixmap size is changed.

Note: GetShift(mask) will return 0 for a mask of

Olivier Fourdan cd999f08c6 xwayland: Use multiple window buffers
Xwayland takes care of not attaching a new buffer if a frame callback is
pending.

Yet, the existing buffer (which was previously attached) may still be
updated from the X11 side, causing unexpected visual glitches to the
buffer.

Add multiple buffering to the xwl_window and alternate between buffers,
to leave the Wayland buffer untouched between frame callbacks and avoid
stuttering or tearing issues.

Olivier Fourdan 1c6f875f52 xwayland: Add multiple window buffering support
Add a mechanism to create, recycle and destroy window buffers when
needed.

Typically, this adds a new `xwl_window_buffer` structure which
represents a buffer for a given Xwayland window.

Each Xwayland window has two different pools of buffers:

 - The available buffers pool:
   Those are buffers which where created previously and that have either
   not been submitted to the compositor or submitted and released.

 - The unavailable buffers pool:
   Those are typically the buffers which are being used by the
   compositor, awaiting a release.

Initially, an Xwayland window starts with both pools empty. As soon as a
new buffer is needed, it's either created (if there is none available)
or picked from the pool of available buffers.

Once submitted to the compositor, the buffer is moved to the pool of
unavailable buffers. When the corresponding `wl_buffer` is released by
the compositor, it is moved back to pool of available buffers again to
be reused when needed.

To avoid keeping too many buffers around doing nothing, a garbage
collection of older, unused buffers also takes care of disposing the
buffers being unused for some time.

Olivier Fourdan 7765874186 xwayland: Add buffer release callback
The API `wl_buffer_add_listener` is misleading in the sense that there
can be only one `wl_buffer` release callback, and trying to add a new
listener when once is already in place will lead to a protocol error.

The Xwayland EGL backends may need to set up their own `wl_buffer`
release listener, meaning that there is no way to our own `wl_buffer`
release callback.

To avoid the problem, add our own callback API to be notified when the
`wl_buffer` associated with an `xwl_pixmap` is released, triggered from
the different `xwl_pixmap` implementations.

Also update the Present code to use the new buffer release callback API.

Kenneth Graunke 8d4be7f6c4 modesetting: Use EGL_MESA_query_driver to select DRI driver if possible
New now ask Glamor to use EGL_MESA_query_driver to obtain the DRI driver
name; if successful, we use that as the DRI driver name.  Following the
existing dri2.c logic, we also use the same name for the VDPAU driver,
except for i965 (and now iris), where we switch to the "va_gl" fallback.

This allows us to bypass the PCI ID lists in xserver and centralize the
driver selection mechanism inside Mesa.  The hope is that we no longer
have to update these lists for any future hardware.
