Emil Velikov 7ec350ddd4 xfree86: remove aiglx cmd/xorg.conf option
The option is misleading and using it leads to disabling both direct and
accelerated indirect GLX. In such cases the xserver GLX attempts to
match DRISW (IGLX) configs with the DRI2/3 ones (direct GLX) leading to
all sorts of fun experience.

Remove the option until we get a clear split and control over direct vs
indirect GLX.

Jonas Ådahl a6e85e6330 xwayland: Add pointer warp emulator
Emulate pointer warps by locking the pointer and sending relative
motion events instead of absolute. X will keep track of the "fake"
pointer cursor position given the relative motion events, and the
client warping the cursor will warp the faked cursor position.

Various requirements need to be met for the pointer warp emulator to
enable:

The cursor must be invisible: since it would not be acceptable that a
fake cursor position would be different from the visual representation
of the cursor, emulation can only be done when there is no visual
representation done by the Wayland compositor. Thus, for the emulator
to enable, the cursor must be hidden, and would the cursor be displayed
while the emulator is active, the emulator would be destroyed.

The window that is warped within must be likely to have pointer focus.
For example, warping outside of the window region will be ignored.

The pointer warp emulator will disable itself once the fake cursor
position leaves the window region, or the cursor is made visible.

This makes various games depending on pointer warping (such as 3D
first-person shooters and stategy games using click-to-drag-map like
things) work.

Translate grabbing a pointer device with confineTo set to a window into
confining the Wayland pointer using the pointer constraints protocol.
This makes clients that depend on the pointer not going outside of the
window region, such as certain games and virtual machines viewers, to

Jonas Ådahl b4644ce8d3 xwayland: Set unaccelerated pointer motion delta if available
If there was an relative pointer motion within the same frame as an
absolute pointer motion, provide both the absolute coordinate and the
unaccelerated delta when setting the valuator mask.

If a frame contained only a relative motion, queue an absolute motion
with an unchanged position, but still pass the unaccelerated motion
event.

If the wl_seat advertised by the compositor is not new enough, assume
each relative and absolute pointer motion arrives within their own

Carlos Garnacho ee52628588 xwayland: Apply "last pointer window" check only to the pointer device
The checks in xwayland's XYToWindow handler pretty much assumes that the
sprite is managed by the wl_pointer, which is not entirely right, given
1) The Virtual Core Pointer may be controlled from other interfaces, and
2) there may be other SpriteRecs than the VCP's.

This makes XYToWindow calls return a sprite trace with just the root
window if any of those two assumptions are broken, eg. on touch events.

So turn the check upside down, first assume that the default XYToWindow
proc behavior is right, and later cut down the spriteTrace if the
current device happens to be the pointer and is out of focus. We work
our way to the device's lastSlave here so as not to break assumption #1
above.

drmModeSetCursor2() will always return -EINVAL.  Specifically, a return

We get multiple udev events for actions like docking a laptop into its
station or plugging a monitor to the station. By consuming as much
events as we can, we reduce the number of output re-evalutions.

I.e. having a Lenovo X250 in a ThinkPad Ultra Dock and plugging a
monitor to the station generates 5 udev events. Or having 2 monitors
attached to the station and docking the laptop generates 7 events.

It depends on the timing how many events can consumed at once.

Laszlo Ersek ca8d88e503 xfree86: recognize primary BUS_PCI device in xf86IsPrimaryPlatform()
The new platform bus code and the old PCI bus code overlap. Platform bus
can handle any type of device, including PCI devices, whereas the PCI code
can only handle PCI devices. Some drivers only support the old style
PCI-probe methods, but the primary device detection code is server based,
not driver based; so we might end up with a primary device which only has
a PCI bus-capable driver, but was detected as primary by the platform
code, or the other way around.

(The above paragraph was shamelessly stolen from Hans de Goede, and
customized.)

The latter case applies to QEMU's virtio-gpu-pci device: it is detected as
a BUS_PCI primary device, but we actually probe it first (with the
modesetting driver) through xf86platformProbeDev(). The
xf86IsPrimaryPlatform() function doesn't recognize the device as primary
(it bails out as soon as it sees BUS_PCI); instead, we add the device as a
secondary graphics card under "autoAddGPU". In turn, the success of this
automatic probing-as-GPU prevents xf86CallDriverProbe() from proceeding to
the PCI probing.

The result is that the server exits with no primary devices detected.

Commit cf66471353 ("xfree86: use udev to provide device enumeration for
kms devices (v10)") added "cross-bus" matching to xf86IsPrimaryPci(). Port
that now to xf86IsPrimaryPlatform(), so that we can probe virtio-gpu-pci
as a primary card in platform bus code.

Hans de Goede 02ff0a5d7e xf86RandR12: Fix XF86VidModeSetGamma triggering a BadImplementation error
Commit b4e46c0444 ("xfree86: Hook up colormaps and RandR 1.2 gamma code")
dropped the providing of a pScrn->ChangeGamma callback from the xf86RandR12
code. Leaving pScrn->ChangeGamma NULL in most cases.

This triggers the BadImplementation error in xf86ChangeGamma() :

    if (pScrn->ChangeGamma)
        return (*pScrn->ChangeGamma) (pScrn, gamma);

    return BadImplementation;

Which causes X-apps using XF86VidModeSetGamma to crash with a
X protocol error.

This commit fixes this by re-introducing the xf86RandR12ChangeGamma
helper removed by the commit and adjusting it to work with the new
combined palette / gamma code.

Hans de Goede 299cbb9267 modesetting: Fix reverse prime update lagging on secondary GPU outputs
When using secondary GPU outputs the primary GPU's blockhandler
will copy changes from its framebuffer to a pixmap shared with the
secondary GPU.

In reverse prime setups the secondary GPU's blockhandler will do another
copy from the shared pixmap to its own framebuffer.

Before this commit, if the primary GPU's blockhandler would run after
the secondary GPU's blockhandler and no events were pending, then the
secondary GPU's blockhandler would not run until some events came in
(WaitForSomething() would block in the poll call), resulting in the
secondary GPU output sometimes showing stale contents (e.g. a just closed
window) for easily up to 10 seconds.

This commit fixes this by setting the timeout passed into the
blockhandler to 0 if any shared pixmaps were updated by the primary GPU,
forcing an immediate re-run of all blockhandlers.

When using reverse prime we do 2 copies, 1 from the primary GPU's

secondary GPU's framebuffer.

This means that on the primary GPU side the copy MUST be finished,
before we start the second copy (before the secondary GPU's driver
starts processing the damage on the shared pixmap).

This fixes secondary outputs sometimes showning (some) old fb contents,
because of the 2 copies racing with each other, for an example of
what this looks like see:

Olivier Fourdan 862a3dab28 xwayland: Clear up x_cursor on UnrealizeCursor()
In Xwayland's xwl_unrealize_cursor(), the x_cursor is cleared up only
when a device value is provided to the UnrealizeCursor() routine, but
if the device is NULL as called from FreeCursor(), the corresponding
x_cursor for the xwl_seat is left untouched.

This might cause a segfault when trying to access the unrealized
cursor's devPrivates in xwl_seat_set_cursor().

A possible occurrence of this is the client changing the cursor, the
Xserver calling FreeCursor() which does UnrealizeCursor() and then
the Wayland server sending a pointer enter event, which invokes
xwl_seat_set_cursor() while the seat's x_cursor has just been
unrealized.

To avoid this, walk through all the xwl_seats and clear up all x_cursor
matching the cursor being unrealized.

Olivier Fourdan b79eaf1184 xwayland: handle EAGAIN on Wayland fd
wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.

When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.

The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.

What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.

This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.

Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.

Jon Turney f5f4d32ac7 Add Windows-DRI extension
If windowsdriproto headers are available, build a Windows-DRI extension,
which supports requests to enable local clients to directly render GL to a
Windows drawable:

- a query to check if WGL is being used on a screen
- a query to map a fbconfigID to a native pixelformatindex
- a query to map a drawable to a native handle

Windows-DRI can only be useful if we are using WGL, so make an note if WGL
is active on a screen.

Make validGlxDrawable() public

Adjust glxWinSetPixelFormat() so it doesn't require a context, just a
screen and config.

That enables factoring out the deferred drawable creation code as
glxWinDeferredCreateDrawable()

Enhance glxWinDeferredCreateDrawable(), so that pixmaps are placed into a
file mapping, so they exist in memory which can be shared with the direct
rendering process.

Currently, this file mapping is accessed by a name generated from the XID.
This will not be unique across multiple server instances. It would perhaps
be better, although more complicated, to use an anonymous file mapping, and
then duplicate the handle for the direct rendering process.

Use glxWinDeferredCreateDrawable() to ensure the native handle exists for
the Windows-DRI query to map a drawable to native handle.

v2:
Various printf format warning fixes

v3:
Fix format warnings on x86
Move some uninteresting windows-dri output to debug log level

v4:
check for windowsdriproto when  --enable-windowsdri
use windowsdriproto_CFLAGS

Hans de Goede df88008f92 xf86Cursor: Deal with rotation on GPU screens using a hw-cursor
When a slave-output is rotated the transformation is done on the blit
from master to slave GPU, so crtc->transform_in_use is not set, but we
still need to adjust the mouse position for things to work.

This commit modifies xf86_crtc_transform_cursor_position to not rely
on crtc->f_framebuffer_to_crtc, so that it can be used with GPU screens
too and always calls it for crtcs with any form of rotation.

Note not using crtc->f_framebuffer_to_crtc means that crtc->transform
will not be taken into account, that is ok, because when we've a transform
active hw-cursors are not used and xf86_crtc_transform_cursor_position
will never get called.

Adam Jackson 392da389d7 glx: Fix computation of GLX_X_RENDERABLE fbconfig attribute
>From the GLX spec:

    "GLX_X_RENDERABLE is a boolean indicating whether X can be used to
    render into a drawable created with the GLXFBConfig. This attribute
    is True if the GLXFBConfig supports GLX windows and/or pixmaps."

Every backend was setting this to true unconditionally, and then the
core ignored that value and sent true unconditionally on its own. This
is broken for ARB_fbconfig_float and EXT_fbconfig_packed_float, which
only apply to pbuffers, which are not renderable from non-GLX APIs.

Instead compute GLX_X_RENDERABLE from the supported drawable types. The
dri backends were getting _that_ wrong too, so fix that as well.

This is not a functional change, as there are no mesa drivers that claim
to support __DRI_ATTRIB_{UNSIGNED_,}FLOAT_BIT yet.

Rui Matos 589f42e983 xwayland: Process queued events before making wayland mods effective
Since xwayland's initial commit we have had a check to not process
wayland modifier events while one of our surfaces has keyboard focus
since the normal xkb event processing keeps our internal modifier
state up to date and if we use the modifiers we get from the
compositor we mess up that state.

This was slightly changed in commit
10e9116b3f to allow the xkb group to be
set from the wayland event while we have focus in case the compositor
triggers a group switch.

There's a better solution to the original problem though. Processing
queued events before overriding the xkb state with the compositor's
allows those events to be sent properly modified to X clients while
any further events will be modified with the wayland modifiers as
intended.

This allows us to fully take in the wayland modifiers, including
depressed ones, which fixes an issue where we wouldn't be aware of
already pressed modifiers on enter.

When Xorg gets started directly from a wayland-gdm the crtc still has the

Hans De Goede 48c5c23a1b Fix Xorg -configure not working anymore
Xorg -configure relies on the bus implementation, e.g.
xf86pciBus.c to call xf86AddBusDeviceToConfigure(). The new
xf86platformBus code does not have support for this.

Almost all drivers support both the xf86platformBus and xf86pciBus
nowadays, and the generic xf86Bus xf86CallDriverProbe() function
prefers the new xf86platformBus probe method when available.

Since the platformBus paths do not call xf86AddBusDeviceToConfigure()
this results in Xorg -configure failing with the following error:
"No devices to configure.  Configuration failed.".

Adding support for the xf86Configure code to xf86platformBus.c
is non trivial and since we advise users to normally run without
any Xorg.conf at all not worth the trouble.

However some users still want to use Xorg -configure to generate a
template config file, this commit implements a minimal fix to make
things work again for PCI devices by skipping the platform
probe method when xf86DoConfigure is set.

This has been tested on a system with integrated intel graphics,
with both the intel and modesetting drivers and restores Xorg -configure
functionality on both cases.

Matthieu Herrb 611b3b1d40 Autoconfig: Fix the loop adding dectected drivers to the list of screens
This loop was written in a buggy style, causing a NULL driver ptr to be
passed to copyScreen(). copyScreen() only uses that to generate an
identifier string, so this is mostly harmless on systems that accept
NULL for asprintf() "%s" format. (the generated identifiers are off
by one wrt the driver names and the last one contains NULL.

For systems that don't accept NULL for '%s' this would cause a
segmentation fault when this code is used (no xorg.conf, but partial
config in xorg.conf.d for instance).

Peter Hutterer f399919e13 xfree86: lock input during PreInit
This is a problem for the libinput driver that uses the same context across
multiple devices. The driver may be halfway through setting up an input device
(and the only way to do so is to add it to libinput) when the input thread
comes in an reads events. This then causes mayhem when data is dereferenced
that hasn't been set up yet.

In my case the cause was the call to libinput_path_remove_device() inside
preinit racing with evdev_dispatch_device() handling of ENODEV. The sequence
was:
- thread 2 gets an event and calls evdev_dispatch_device()
- thread 1 calls libinput_path_remove_device() which sets the device->source
  to NULL
- thread 2 reads from the fd, gets ENODEV and now removes the device->source,
  dereferencing the null-pointer

This is the one I could reproduce the most, but there are other potential
pitfalls that affect any driver that uses the same fd for multiple devices.
Avoid all this and wrap PreInit into the lock.

Adam Jackson fcbafdfd79 modesetting: Implement a double-buffered shadow mode
Server GPUs often have a VNC feature attached to allow remote console.
The controller implementing this feature is usually not very powerful,
and we can easily swamp it with work.  This is made somewhat worse by
damage over-reporting the size of the dirty region, and a whole lot
worse by applications (or shells) that update the screen with identical
pixel content as was already there.

Fix this by double-buffering the shadow fb, using memcmp to identify
dirty tiles on each update pass.  Since both shadows are in host memory
the memcmp is cheap, and worth it given the win in network bandwidth.
The tile size is somewhat arbitrarily chosen to be one cacheline wide at
32bpp on Intel Core.

By default we enable this behaviour for (a subset of) known server GPUs;
the heuristic could use work.

Takashi Iwai af916477c6 modesetting: Fix hw cursor check at the first call
With the previous patch, the modesetting driver can now return whether
the driver supports hw cursor.  However, it alone doesn't suffice,
unfortunately. drmmode_load_cursor_argb_check() is called in the
following chain:

  xf86CursorSetCursor()
    -> xf86SetCursor()
       -> xf86DriverLoadCursorARGB()
         -> xf86_load_cursor_argb()
           -> xf86_crtc_load_cursor_argb()
             -> drmmode_load_cursor_argb_check()

*but* at first with drmmode_crtc->cursor_up = FALSE.  Then the
function doesn't actually set the cursor but returns TRUE
unconditionally.  The actual call of drmmode_set_cursor() is done at
first via the show_cursor callback, and there is no check of sw cursor
fallback any longer at this place. Since it's called only once per
cursor setup, so the xserver still thinks as if the hw cursor is
supported.

This patch is an ad hoc fix to correct the behavior somehow: it does
call drmmode_set_cursor() at the very first time even if cursor_up is
FALSE, then quickly hides again.  In that way, whether the hw cursor
is supported is evaluated in the right place at the right time.

Of course, it might be more elegant if we have a more proper mechanism
to fall back to sw cursor at any call path.  But it'd need more
rework, so I leave this workaround as is for now.

Takashi Iwai 14c21ea1c9 modesetting: Use load_cursor_argb_check for sw cursor fallback
The modesetting driver still has an everlasting bug of invisible
cursor on cirrus and other KMS drivers where no hardware cursor is
supported.  This patch is a part of an attempt to address it.

This patch particularly converts the current load_cursor_argb callback
of modesetting driver to load_cursor_argb_check so that it can return
whether the driver handles the hw cursor or falls back to the sw
cursor.

Alex Goins 44cb9578c0 modesetting: Disable Reverse PRIME for i915
Reverse PRIME seems to be designed with discrete graphics as a sink in
mind, designed to do an extra copy from sysmem to vidmem to prevent a
discrete chip from needing to scan out from sysmem.

The criteria it used to detect this case is if we are a GPU screen and
Glamor accelerated. It's possible for i915 to fulfill these conditions,
despite the fact that the additional copy doesn't make sense for i915.

Normally, you could just set AccelMethod = none as an option for the device
and call it a day. However, when running with modesetting as both the sink
and the source, Glamor must be enabled.

Ideally, you would be able to set AccelMethod individually for devices
using the same driver, but there seems to be a bug in X option parsing that
makes all devices on a driver inherit the options from the first detected
device. Thus, glamor needs to be enabled for all or for none until that bug
(if it's even a bug) is fixed.

Nonetheless, it probably doesn't make sense to do the extra copy on i915
even if Glamor is enabled for the device, so this is more user friendly by
not requiring users to disable acceleration for i915.

Alex Goins f6fef2a171 modesetting: Blacklist USB transport devices from PRIME sync
UDL (USB 2.0 DisplayLink DRM driver) and other drivers for USB transport devices
have strange semantics when it comes to vblank events, due to their inability to
get the actual vblank info.

When doing a page flip, UDL instantly raises a vblank event without waiting for
vblank. It also has no support for DRM_IOCTL_WAIT_VBLANK, and has some strange
behavior with how it handles damage when page flipping.

It's possible to get something semi-working by hacking around these issues,
but even then there isn't much value-add vs single buffered PRIME, and it
reduces maintainability and adds additional risks to the modesetting driver
when running with more well-behaved DRM drivers.

Work needs to be done on UDL in order to properly support synchronized
PRIME. For now, just blacklist it, causing RandR to fall back to
unsynchronized PRIME.

This patch originally blacklisted UDL by name, but it was pointed out that there
are other USB transport device drivers with similar limitations, so it was
expanded to blacklist all USB transport devices.

Alex Goins 80e64dae8a modesetting: Implement PRIME syncing as a sink
Implements (Enable/Disable)SharedPixmapFlipping and
SharedPixmapNotifyDamage, the sink functions for PRIME synchronization and
double buffering. Allows modesetting driver to be used as a sink with PRIME
synchronization.

Changes dispatch_slave_dirty to flush damage from both scanout pixmaps.

Changes drmmode_set_scanout_pixmap*() functions to
drmmode_set_target_scanout_pixmap*() that take an additional parameter
PixmapPtr *target. Then, treat *target as it did prime_pixmap. This allows
me to use it to explicitly set both prime_pixmap and prime_pixmap_back
individually. drmmode_set_scanout_pixmap() without the extra parameter
remains to cover the single-buffered case, but only works if we aren't
already double buffered.

driver.c:
    Add plumbing for rr(Enable/Disable)SharedPixmapFlipping and
    SharedPixmapNotifyDamage.

    Change dispatch_dirty_crtc to dispatch_dirty_pixmap, which functions the
    same but flushes damage associated with a ppriv instead of the crtc, and
    chanage dispatch_slave_dirty to use it on both scanout pixmaps if
    applicable.

drmmode_display.h:
    Add flip_seq field to msPixmapPrivRec to keep track of the event handler
    associated with a given pixmap, if any.

    Add wait_for_damage field to msPixmapPrivRec to keep track if we have
    requested a damage notification from the source.

    Add enable_flipping field to drmmode_crtc_private_rec to keep track if
    flipping is enabled or disabled.

    Add prime_pixmap_back to drmmode_crtc_private_rec to keep track of back
    buffer internally.

    Add declarations for drmmode_SetupPageFlipFence(),
    drmmode_EnableSharedPixmapFlipping(),
    drmmode_DisableSharedPixmapFlipping, drmmode_SharedPixmapFlip(), and
    drmmode_SharedPixmapPresentOnVBlank().

    Move slave damage from crtc to ppriv.

drmmode_display.c:
    Change drmmode_set_scanout_pixmap*() functions to
    drmmode_set_target_scanout_pixmap*() that take an additional parameter
    PixmapPtr *target for explicitly setting different scanout pixmaps.

    Add definitions for functions drmmode_SharedPixmapFlip(),
    drmmode_SharedPixmapPresentOnVBlank(),
    drmmode_SharedPixmapPresent(),
    drmmode_SharedPixmapVBlankEventHandler(),
    drmmode_SharedPixmapVBlankEventAbort(),
    drmmode_EnableSharedPixmapFlipping(), and
    drmmode_DisableSharedPixmapFlipping,
    drmmode_InitSharedPixmapFlipping(), and
    drmmode_FiniSharedPixmapFlipping, along with struct
    vblank_event_args.

    The control flow is as follows:
        pScrPriv->rrEnableSharedPixmapFlipping() makes its way to
        drmmode_EnableSharedPixmapFlipping(), which sets enable_flipping to
        TRUE and sets both scanout pixmaps prime_pixmap and
        prime_pixmap_back.

        When setting a mode, if prime_pixmap is defined, modesetting
        driver will call drmmode_InitSharedPixmapFlipping(), which if
        flipping is enabled will call drmmode_SharedPixmapPresent() on
        scanout_pixmap_back.

        drmmode_SharedPixmapPresent() requests that for the source to
        present on the given buffer using master->PresentSharedPixmap(). If
        it succeeds, it will then attempt to flip to that buffer using
        drmmode_SharedPixmapFlip(). Flipping shouldn't fail, but if it
        does, it will raise a warning and try drmmode_SharedPixmapPresent()
        again on the next vblank using
        drmmode_SharedPixmapPresentOnVBlank().

        master->PresentSharedPixmap() could fail, in most cases because
        there is no outstanding damage on the mscreenpix tracked by the
        shared pixmap. In this case, drmmode_SharedPixmapPresent() will
        attempt to use master->RequestSharedPixmapNotifyDamage() to request
        for the source driver to call slave->SharedPixmapNotifyDamage() in
        response to damage on mscreenpix. This will ultimately call
        into drmmode_SharedPixmapPresentOnVBlank() to retry
        drmmode_SharedPixmapPresent() on the next vblank after
        accumulating damage.

        drmmode_SharedPixmapFlip() sets up page flip event handler by
        packing struct vblank_event_args with the necessary parameters, and
        registering drmmode_SharedPixmapVBlankEventHandler() and
        drmmode_SharedPixmapVBlankEventAbort() with the modesetting DRM
        event handler queue. Then, it uses the drmModePageFlip() to flip on
        the next vblank and raise an event.

        drmmode_SharedPixmapPresentOnVBlank() operates similarly to
        drmmode_SharedPixmapFlip(), but uses drmWaitVBlank() instead of
        drmModePageFlip() to raise the event without flipping.

        On the next vblank, DRM will raise an event that will ultimately be
        handled by drmmode_SharedPixmapVBlankEventHandler(). If we flipped,
        it will update prime_pixmap and prime_pixmap_back to reflect that
        frontTarget is now being displayed, and use
        drmmode_SharedPixmapPresent(backTarget) to start the process again
        on the now-hidden shared pixmap. If we didn't flip, it will just
        use drmmode_SharedPixmapPresent(frontTarget) to start the process
        again on the still-hidden shared pixmap.

        Note that presentation generally happens asynchronously, so with
        these changes alone tearing is reduced, but we can't always
        guarantee that the present will finish before the flip. These
        changes are meant to be paired with changes to the sink DRM driver
        that makes flips wait on fences attached to dmabuf backed buffers.
        The source driver is responsible for attaching the fences and
        signaling them when presentation is finished.

        Note that because presentation is requested in response to a
        vblank, PRIME sources will now conform to the sink's refresh rate.

        At teardown, pScrPriv->rrDisableSharedPixmapFlipping() will be
        called, making its way to drmmode_FiniSharedPixmapFlipping().
        There, the event handlers for prime_pixmap and prime_pixmap_back
        are aborted, freeing the left over parameter structure. Then,
        prime_pixmap and prime_pixmap back are unset as scanout pixmaps.

    Register and tear down slave damage per-scanout pixmap instead of
    per-crtc.

Alex Goins b773a9c812 modesetting: Always tear down scanout pixmap
drmmode_set_scanout_pixmap_(cpu/gpu) would only do teardown if ppix ==
NULL. This meant that if there were consecutive calls to
SetScanoutPixmap(ppix != NULL) without calls to SetScanoutPixmap(ppix ==
NULL) in between, earlier calls would be leaked.  RRReplaceScanoutPixmap()
does this today.

Instead, when setting a scanout pixmap, always do teardown of the existing
scanout pixmap before setting up the new one. Then, if there is no new one
to set up, stop there.

This maintains the previous behavior in all cases except those with
multiple consecutive calls to SetScanoutPixmap(ppix != NULL).

Alex Goins f4c37eeee7 modesetting: Internal storage of scanout pixmaps
modesetting relied on randr_crtc->scanout_pixmap being consistent with
calls to SetScanoutPixmap, which is very fragile and makes a lot of
assumptions about the caller's behavior.

For example, RRReplaceScanoutPixmap(), when dropping off with !size_fits,
will set randr_crtc->scanout_pixmap = NULL and then call SetScanoutPixmap.
Without this patch, drmmode_set_scanout_pixmap_(cpu/gpu) will think that
there is no scanout pixmap to tear down, because it's already been set to
NULL.

By keeping track of the scanout pixmap in its internal state, modesetting
can avoid these types of bugs and reduce constraints on calling
conventions.

Olivier Fourdan 7397a2191f xwayland-input: Fake crossing to rootwin
This partially reverts commit c1565f3.

When the pointer moves from an X11 window to a Wayland native window,
no LeaveNotify event is emitted which can lead to various unexpected
behaviors like tooltips remaining visible after the pointer has left the
window.

Yet the pointer_handle_leave() is called and so is the DIX CheckMotion()
but since the pointer enters a Wayland native window with no other
Xwayland window matching, DoEnterLeaveEvents() does not get invoked and
therefore no LeaveNotify event is sent to the X11 client at the time the
pointer leaves the window for a Wayland native surface.

Restore the XYToWindow() handler in xwayland-input that was previously
removed with commit c1565f3 and use that handler to pretend that the
pointer entered the root window in this case so that the LeaveNotify
event is emitted.

Keith Packard f3248eba6e ephyr: Handle window resize when using glamor
Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new

Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

Keith Packard fb1edccf3c dix: Call screen block/wakeup handlers closest to blocking [v3]
The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.

Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.

Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.

These changes ensure that the following modules update the screen in
the correct order:

animated cursors        (uses RegisterBlockAndWakeupHandlers dynamically)
composite               (dynamic wrapping)
misprite                (dynamic wrapping)
shadow                  (static wrapping)
glamor                  (static wrapping)
driver                  (static wrapping)

It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.

[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes

ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.

Hans de Goede b8ef71fb07 modesetting: Properly cleanup fb for reverse-prime-offload
drmmode_set_scanout_pixmap_gpu(pix) adds drmmod->fb_id through a call
to drmmode_xf86crtc_resize(), but on a subsequent
drmmode_set_scanout_pixmap_gpu(NULL) it would not remove the fb.

This keeps the crtc marked as busy, which causes the dgpu to not
being able to runtime suspend, after an output attached to the dgpu
has been used once. Which causes burning through an additional 10W
of power and the laptop to run quite hot.

This commit adds the missing remove fb call, allowing the dgpu to runtime
suspend after an external monitor has been plugged into the laptop.

Note this also makes drmmode_set_scanout_pixmap_gpu(NULL) match the
behavior of drmmode_set_scanout_pixmap_cpu(NULL) which was already
removing the fb.

Provider 2: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting

Not good. The problem is that the provider with id 0x46 now is on both
the output_slave_list and the offload_slave_list of the master screen.

This commit fixes this by unifying all 3 lists into a single slaves list.

Note that this does change the struct _Screen definition, so this is an ABI
break. I do not expect any of the drivers to actually use the removed / changed
fields so a recompile should suffice.

Olivier Fourdan 6a6bbc3b75 xwayland: Restore wl_display_roundtrip() in InitInput
This partially revert commit 984be78

The rountrip in Xwayland's InitInput() is unlikely the culprit for the
crash reported in bug 95337, even though it's triggered from
InitInput().

Startup goes like this:

  xwl_screen_init()
    xwl_output_create()
    wl_display_roundtrip()
  InitInput()
    wl_display_roundtrip()
  ConnectionInfo initialized

What happens in bug 95337 is that some output data is already available
when we reach InitInput()'s wl_display_roundtrip() and therefore we end
up trying to update the ConnectionInfo's data from RR routines before
ConnectionInfo is actually initialized.

Removing the wl_display_roundtrip() from InitInput() will not fix the
issue (although it would make it less lileky to happen), because
xwl_screen_init() also does a wl_display_roundtrip() after creating the
output, so the race that led to bug 95337 remains.

However, re-setting the xwl_screen->expecting_event to 0 again in
InitInput() still doesn't seem right. so this part is not restored
(thus a partial revert).
