This FD also triggers the "wait for WM_S0" paths, so that the
compositor may set up a "maintenance line" for Xwayland, for
services that are essential to run before any client (eg. xrdb).
Those services would use this FD, disguised as an extra display
connection.
This -initfd can be seen as a generalization of -wm, a Wayland
compositor may use -initfd to launch its WM and any other clients
that should start up, or it may use -wm as a dedicated connection for
the WM and optionally use -initfd for the misc. startup clients.
If either of -wm or -initfd is passed, Xwayland will expect a selection
notification on WM_S0 before incorporating the FDs in -listen to the
poll list.
Also, correct a minor typo in the listenfd argument output,

If Xwayland gets to realize a window meant for composition before the
compositor redirected windows (i.e. redirect mode is not RedirectDrawManual
yet), the window would stay "invisible" as we wouldn't create a
wl_surface/wl_shell_surface for it at any later point.
This scenario may happen if the wayland compositor sets up a X11 socket
upfront, but waits to raise Xwayland until there are X11 clients. In this
case the first data on the socket is the client's, the compositor can hardly
beat that in order to redirect subwindows before the client realizes a
Window.
In order to jump across this hurdle, allow the late creation of a matching
(shell) surface for the WindowPtr on SetWindowPixmapProc, so it is ensured
to be created after the compositor set up redirection.

This is a modified version of a patch we've been carry-ing in Fedora and
RHEL for years now. This patch automatically adds secondary GPUs to the
master as output sink / offload source making e.g. the use of
slave-outputs just work, with requiring the user to manually run
"xrandr --setprovideroutputsource" before he can hookup an external
monitor to his hybrid graphics laptop.
There is one problem with this patch, which is why it was not upstreamed
before. What to do when a secondary GPU gets detected really is a policy
decission (e.g. one may want to autobind PCI GPUs but not USB ones) and
as such should be under control of the Desktop Environment.
Unconditionally adding autobinding support to the xserver will result
in races between the DE dealing with the hotplug of a secondary GPU
and the server itself dealing with it.
However we've waited for years for any Desktop Environments to actually
start doing some sort of autoconfiguration of secondary GPUs and there
is still not a single DE dealing with this, so I believe that it is
time to upstream this now.
To avoid potential future problems if any DEs get support for doing
secondary GPU configuration themselves, the new autobind functionality
is made optional. Since no DEs currently support doing this themselves it
is enabled by default. When DEs grow support for doing this themselves
they can disable the servers autobinding through the servers cmdline or a
xorg.conf snippet.

The rrGetInfo hook is not called for all RANDR requests (e.g.

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

Separate each statement of the form "assert(a && b);" into "assert(a);"

use in drmmode_display.c where it was used to pass a hint to developers:
assert(num_infos <= 32 && "update return type");
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.

If the user sets Option "Enable" "TRUE" for a monitor, the X

However the user in this case is mutter, when it gets it's view

Xorg has code to listen for stops of systemd-logind and terminate

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().

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.

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

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

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.
This-makes-me: ☹
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.

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.
Fixes issue #12. Presumably the problem was that Present operations on
unmapped windows were executed immediately instead of only when reaching
the target MSC.
When a window is unrealized, a pending frame callback may never be
called, which could result in repeatedly freezing until the frame timer
fires after a second.
Fixes these symptoms when switching from fullscreen to windowed mode in
sauerbraten.
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.
There are logically server state not screen state. Not that multiple
screens works, at the moment, but that's no excuse to be sloppy.

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.

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.
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 ()

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.
