There was a time when setting a mode on a CRTC would not depend on the
associated connector's state. If a mode had been set successfully once,
it would mean it would work later on.
This changed with the introduction of new connectors type that now
require a link training sequence (DP, HDMI 2.0), and that means that
some events may have happened while the X server was not master that
would then prevent the mode from successfully be restored to its
previous state.
This patch relaxes the requirement that all modes should be restored on
EnterVT, or the entire X-Server would go down by allowing modesets to
fail (with some warnings). If a modeset fails, the CRTC will be
disabled, and a RandR event will be sent for the desktop environment to
fix the situation as well as possible.
Additional patches might be needed to make sure that the user would
never be left with all screens black in some scenarios.

- improve the commit message
- reduce the size of the patch by not changing lines needlessly

Normally, we would receive a uevent coming from Linux's DRM subsystem,
which would trigger the check for disappearing/appearing resources.
However, this event is not received when X is not master (another VT
is selected), and so the userspace / desktop environment would not be
notified about the changes that happened while X wasn't master.
To fix the issue, this patch forces a refresh on EnterVT by splitting
the kms-checking code from the uevent handling into its own (exported)
function called drmmode_update_kms_state. This function is then called
from both the uevent-handling function, and on EnterVT right before
restoring the modes.

The EGLStream backend keeps a queue of pending streams for each Xwayland
window.
However, when this pending queue is freed, the corresponding private
data may not be cleared (typically if the pixmap for this window has
changed before the compositor finished attaching the consumer for the
window's pixmap's original eglstream), leading to a use-after-free and a
crash when trying to use that data as the window pixmap.
Make sure to clear the private data when the pending stream is freed.

These changes have been ported from AMD GPU DDX driver.
This patch adds support for setting the CRTC variable refresh property
for suitable windows flipping via the Present extension.
In order for a window to be suitable for variable refresh it must have
the _VARIABLE_REFRESH property set by the MESA and inform Modesetting
DDX driver with window property updates.
Then the window must pass the checks required to be suitable for
Present extension flips - it must cover the entire X screen and no
other window may already be flipping. And also DRM connector should
be VRR capable.
With these conditions met every CRTC for the X screen will have their
variable refresh property set to true.

This reverts commit 427f8bc009.
When receiving an output update for the mode size we need to rotate the stored

since in this case the stored values describe the output's size in logical
space, i.e. rotated.
The here reverted commit made a code change with which we would not rotate though
when an xdg-output was available since in this case the need_rotate variable was
set to False what caused in the check afterwards the first branch to execute.
That is just a small style-change to the output_get_new_size function. The
function before did take first the height and then the width argument, what
is unusual since resolutions are normally named the other way around, for
example 1920x1080. Also compare the update_screen_size function.

Xwayland is usually spawned by the Wayland compositor which sets the
command line options.
If a command line option is not supported, Xwayland will fail to start.
That somehow makes the Xwayland command line option sort of ABI, the
Wayland compositor need to know if a particular option is supported by
Xwayland at build time.
Also, currently, Xwayland is being installed along with the rest of the
common executable programs that users may run, which is sub-optimal
because, well, Xwayland is not a common executable program, it's meant
to be a proxy between the Wayland compositor and the legacy X11 clients
which wouldn't be able to run on Wayland otherwise.
Xwayland would be better installed in `libexec` but that directory is
(purposedly) not in the user `PATH` and therefore the Wayland compositor
may not be able to find Xwayland in that case.
To solve both problems (which options are supported by Xwayland and
where to look for it), add a `pkg-config` file specifically for Xwayland
which gives the full path to Xwayland (`xwayland`) and which options it
supports (using `pkg-config` variables).
The `pkg-config` file also provides the `Version` so the build scripts
can check for a particular version if necessary.
Obviously, Wayland compositors are not required to use the `pkg-config`
file and can continue to use whatever mechanism they deem preferable.

The way Xwayland works (like all Wayland clients), it first queries the
Wayland registry, set up all relevant protocols and then initializes its
own structures.
That means Xwayland will get the Wayland outputs from the Wayland
compositor, compute the physical size of the combined outputs and set
the corresponding Xwayland screen properties accordingly.
Then it creates the X11 screen using fbScreenInit() but does so by using
a default DPI value of 96. That value is used to set the physical size
of the X11 screen, hence overriding the value computed from the actual
physical size provided by the Wayland compositor.
As a result, the DPI computed by tools such as xdpyinfo will always be
96 regardless of the actual screen size and resolution.
However, if the Wayland outputs get reconfigured, or new outputs added,
or existing outputs removed, Xwayland will recompute and update the
physical size of the screen, leading to an unexpected change of DPI.
To avoid that discrepancy, use a fixed size DPI (defaults to 96, and can
be set using the standard command lime option "-dpi") and compute a
physical screen size to match that DPI setting.
Note that only affects legacy core protocols, X11 clients can still get
the actual physical output size as reported by the Wayland compositor
using the RandR protocol, which also allows for the size to be 0 if the
size is unknown or meaningless.

does already reflect the size. Use this to find out the better window to
assign the confining grab to, one whose geometry fully contains the InputOnly
window's.

When an X11 client issues a ConfinePointer wit ha hidden cursor,
Xwayland may translate that as a pointer lock.
However, if the pointer is located on another window at the time,
the request may be ignored, even if the pointer later enters the window.
To avoid that issue, check again if locking the pointer with a hidden
cursor is needed when pointer enters a surface.

When an X11 client has an active grab on the pointer, all events are
reported relative to the window with the grab.
For Xwayland, if an X11 client has a grab with a pointer confinement
active, while pointer focus is on another window, motion events should
not be reported to the client with the grab, because that sets the X11
client appart, the events would be reported when the pointer is on any
X11 window but not on Wayland native surfaces.
Therefore, if the pointer is confined on a window and that window
differs from the actual pointer focus window, just pretend we lost
pointer focus to another window.

If a client issues a grab on the pointer while the cursor is on another
X11 window, and then hides the cursor, we may end up locking the pointer
onto that other window.
Then a button click might end up moving the focus away from the window
which issued the grab, leaving the whole setup in a mixed up state.
Typically, if the pointer is on another X11 window, we should not try to
lock the pointer, so that it can be moved back to the window which
actually issues the grab (and hence the pointer confinement). Typically,
this is the same as an X11 client issuing a pointer grab while the
cursor is on another Wayland native window.

Mutter recently added headless tests, and when running those tests the
Wayland compositor runs for a very short time.
Xwayland is spawned by the Wayland compositor and upon startup will
query the various Wayland protocol supported by the compositor.
To do so, it will do a roundtrip to the Wayland server waiting for
events it expects.
If the Wayland compositor terminates before Xwayland has got the replies
it expects, it will loop indefinitely calling `wl_display_roundtrip()`
continuously.
To avoid that issue, add a new `xwl_screen_roundtrip()` that checks for
the returned value from `wl_display_roundtrip()` and fails if it is
negative.

All helper client code now uses xcb, so calling XSetAuthorization() is
no longer needed.
This is the last reference to libX11 from helper clients, so linking
with x11-xcb and libX11 is no longer required.
Also drop (unneeded?) linking with libXau.
Also drop installing these prerequistes on AppvVeyor.
Also move prototypes for functions in winauth.c from win.h into a new
header, winauth.h, and include that where needed.
Convert clipboard integration code from libX11 to xcb
This drops support for COMPOUND_TEXT. Presumably some ancient
(pre-2000) clients exist which support that, but not UTF8_STRING, but we
don't have an example to test with. (Given the nature of the thing, the
users of those clients probably work in CJK languages)
Supporting COMPOUND_TEXT would also involve writing (or extracting from
Xlib) support for the ISO 2022 encoding.
v2:
Fix the length of text property set by a SelectionRequest
The length of the text property is not neccessarily the same as the
length of the clipboard text before it is d2u converted (specifically,
if that contains any '\r\n' sequences, it will be shorter as they are
now just '\n')
Always use CF_UNICODETEXT clipboard format. Windows will automatically
down-convert to CF_TEXT for clients which request that.
This is subtly different in one way: if CF_TEXT is requested, we now
post CF_UNICODETEXT and it is converted to CF_TEXT *in the locale of the
requesting process*. Previously, we would convert to CF_TEXT *in our
locale* and post that.
It looks like the code in the !X_HAVE_UTF8_STRING case didn't actually
work correctly, but fortunately that has never been true...
The original Win32 clipboard API is widely regarded as terrible, since
it relies on clients co-operatively managing the clipboard viewer chain,
and a single buggy client can break it for all other clients.
The last Windows version only supporting that API was Windows XP (5.1),
EOLed in 2014.
(This requires MinGW-w64 w32api 6.0.0 or later for
Add/RemoveClipboardListener correctly exported by the x86_64 user32
implib)
Also, relax the timeout mechanism so it allows 1 second between events,
rather than 1 second for the entire transfer, as transfers of large
pastes can take more than 1 second.
Also, prefer UTF8_STRING encoding to COMPOUND_TEXT encoding
This option was implemented before the drivers were split in ≈2006,
and e.g. XWin still supports it.

For window-manager managed windows, xwl_realize_window is only called for
the window-manager's decoration window and not for the actual client window
on which we should set the _XWAYLAND_RANDR_EMU_MONITOR_RECTS prop.
Usualy this is not a problem since we walk all client windows to update
the property when the resolution is changed through a randr call.
But for apps which first do the randr change and only then create their
window this does not work, and our xwl_output_set_window_randr_emu_props
call in xwl_realize_window is a no-op as that is only called for the wm
decoration window and not for the actual client's window.
This commit fixes this by making ensure_surface_for_window() call
xwl_output_set_window_randr_emu_props on the first and only child of
window-manager managed windows.
Note this also removes the non-functional xwl_output_set_window_randr_emu_props
call from xwl_realize_window, which was intended to do this, but does not
work.

Some clients, which use vidmode to change the resolution when going fullscreen,
create an override-redirect window and never trigger the screen->ResizeWindow
callback we rely on to do the xwl_window_check_resolution_change_emulation().
This causes us to not apply a viewport to them, causing the fullscreen window
to not fill the entire monitor.
This commit adds a call to xwl_window_check_resolution_change_emulation()

ensure_surface_for_window() exits early without creating an xwl_window
for new windows which will not be backed by a wayland surface and which
thus will not have an xwl_window.

This means we need to do something similar in xwl_output_set_emulated_mode()

and we this should remove any emulated modes set by the client.
All callers of xwl_output_set_emulated_mode always pass a mode pointer

When fullscreening a X11 window, mutter moves its window-decoration Window

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[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 code in xf86RandR12Init:
#ifdef PANORAMIX
/* XXX disable RandR when using Xinerama */
if (!noPanoramiXExtension) {
if (xf86NumScreens == 1)
noPanoramiXExtension = TRUE;

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'.

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.

To avoid the problem, add our own callback API to be notified when the

Currently, when a X11 client (usually the X11 window manager from a
Wayland compositor) changes the value of the X11 property
`_XWAYLAND_ALLOW_COMMITS` from `false` to `true`, all pending frame
callbacks on the window are discarded so that the commit occurs
immediately.
Weston uses that mechanism to prevent the content of the window from
showing before it's ready when mapping the window initially, but
discarding the pending frame callbacks has no effect on the initial
mapping of the X11 window since at that point there cannot be any frame
callback on a surface which hasn't been committed yet anyway.
However, discarding pending frame callbacks can be problematic if we
were to use the same `_XWAYLAND_ALLOW_COMMITS` mechanism to prevent
damages to be posted before the X11 toplevel is updated completely
(including the window decorations from the X11 window manager).
Remove the portion of code discarding the pending frame callback,
Xwayland should always wait for a pending frame callback if there's one
before posting new damages.

If the primary output is a slave output, RRFirstOutput() will return a slave

output's devPrivate, which is invalid for non-modesetting outputs, and can
crash.
Changing RRFirstOutput() could have unintended side effects for other callers,

When a pixmap is created with a backing FBO, the FBO should be cleared
to avoid rendering uninitialized memory. This could happen when the
pixmap is rendered without being filled in its entirety.
One example is when a top-level window without a background is
resized. The pixmap would be reallocated to prepare for more pixels,
but uninitialized memory would be rendered in the resize offset until
the client sends a frame that fills these additional pixels.
Another example is when a new top-level window is created without a
background. Uninitialized memory would be rendered after the pixmap is
allocated and before the client sends its first frame.
This issue is only apparent in OpenGL implementations that don't zero

We need the WM to emulate this behavior for these apps to work correctly,

it needs to know about the emulated resolution for the Windows owning
client for each monitor.
This commit adds a _XWAYLAND_RANDR_EMU_MONITOR_RECTS property, which

emulation info. Window-managers can use this to get the emulated

Note SDL2 and SFML do not restore randr resolution when going from
fullscreen -> windowed, I believe this is caused by us still reporting the
desktop resolution when they query the resolution. This is not a problem
because when windowed the toplevel window size includes the window-decorations
so it never matches the emulated resolution.
One exception would be the window being resizable in Windowed mode and the
user resizing the window so that including decorations it matches the
emulated resolution *and* the window being at pos 0x0. But this is an
extreme corner case. Still I will submit patches upstream to SDL2

Currently we parse through xf86Info.debug to check if we the modifiers
should be disabled. Handle that within DDX and pass GLAMOR_NO_MODIFIERS
into the glamor_init() flags.
This allows individual DDX control over the setting - say when modifiers
are woking OK with one implementation and not the other.
Most importantly, this removes the final xf86 piece from the codebase.

Move from the xf86 specific ScrnInfoRec::privates, to the dix private
handling. Since there's no FreeScreen function in ScreenPtr, fold the
former within the existing CloseScreen.
Users, such as modesetting are updated, and out of tree drivers will
need equivalent, yet trivial, patch.
Note: we need to ensure that the screen private is unset and the screen
callbacks are restored in our CloseScreen function.

The autoconf build for the modesetting driver still relied on
xorg-macros.m4 for string replacements and did not include the
top-level manpages.am. As a result, no substitutions took place after
commit 2e497bf887.
This should be a candidate for the 1.20 branch.

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.

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.

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:

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

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.

Xwayland's `xwl_destroy_window()` invokes `xwl_present_cleanup()`
before the common `DestroyWindow()`.
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 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.

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.

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.

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.

To be able to check for availability of the Wayland interfaces required

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

If the pixmap size does not match the present box size, flickering
occurs.
This can happen when the client changes its size (e.g. switching to
fullscreen), and since the buffer is kept as long as the pixmap is
valid, once the buffer is created, it remains at the wrong (old) size
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.

The old 32-Bit wraparound handling didn't actually work, due to some
integer casting bug, and the mapping was ill equipped to deal with input
from the new true 64-bit GetCrtcSequence/QueueCrtcSequence api's
introduced in Linux 4.15.
For 32-Bit truncated input from pageflip events and old vblank events
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.

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.

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.

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.

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.

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.
