This adds support for TearFree page flips to eliminate tearing without the
use of a compositor. It allocates two shadow buffers for each CRTC, a back
buffer and a front buffer, and uses damage tracking to minimize excessive
copying between buffers and skip unnecessary flips when the screen's
contents remain unchanged. It works on transformed screens too, such as
rotated and scaled CRTCs.
When PageFlip is enabled, TearFree won't force fullscreen DRI clients to
synchronize their page flips to the vblank interval.

The DRM event queue in the kernel is quite small and can be easily
exhausted by DRI clients. When the event queue is full, that means nothing
can be queued onto it anymore, which can lead to incorrect presentation
times for DRI clients and failure when attempting to queue a page flip.
To make matters worse, once an event is placed onto the kernel's event
queue, there's no straightforward way to prematurely remove it from the
kernel's event queue in userspace, which means that aborting a sequence
number doesn't free up space in the event queue.
Since vblank events from DRI clients are the largest consumers of the
event queue, and since it's often easy to know the desired target MSC of
their vblank events without querying the kernel for a CRTC's current MSC,
we can coalesce vblank events occurring at the same MSC such that only one
of them is placed onto the kernel's event queue, instead of allowing
duplicate vblank events to pollute the event queue.
This is achieved by tracking the next kernel-queued event's MSC on a
per-CRTC basis and then running all of that CRTC's vblank event handlers
which have reached their target MSC when the queued MSC is signaled.

The current X server infrastructure sets modesetting driver as default driver
to handle PCI-hotplug of a GPU device. This prevents the respective DDX driver
(like AMDGPU DDX driver) to take control of the card.
This patch:
- Adds a few functions and fine-tunes the GPU hotplug infrastructure to allow
the DDX driver to be loaded, if it is configured in the X config file
options as "hotplug-driver".
- Scans and updates the PCI device list before adding the new GPU device
in platform, so that the association of the platform device and PCI device
is in place (dev->pdev).
- Adds documentation of this new option
An example usage in the config file would look like:
Section "OutputClass"
Identifier "AMDgpu"
MatchDriver "amdgpu"
Driver "amdgpu"
HotplugDriver "amdgpu"
EndSection

Commit 8a5f3ddb2 ("set tag on our surface") introduced the use of tags
to differentiate our own surfaces, and commit a1d14aa8c ("Clear the
"xwl-window" tag on unrealize") removed the tags before the surfaces are
actually destroyed.
Xwayland would then rely on these tags on the surface to decide whether
to ignore or to process the Wayland event in various places.
However, in doing so, it also checked for the tag on keyboard leave
events.
As a result, if the keyboard leave events is received after the X11
window is unrealized, keyboard_handle_leave() would not queue the
LeaveNotify events for the DIX to proceed, and the key repeat would
kick in and repeat the key event indefinitely.
To avoid the issue, process events regardless of the tag as before

Because of the design of most Wayland compositors, where the compositor
is both a Wayland server and an X11 window manager, any X11 client
issuing a server grab (i.e. XGrabServer()) can possibly hang the whole
desktop when Xwayland is running rootless.
This can happen with e.g. ImageMagick's import command with mutter.
1. "import" is launched and issues an XServerGrab(),
2. Xwayland restricts access to that "import" X11 client alone,
3. mutter continues to process events until it needs to sync with
Xwayland (there's variability in time before the hang occurs),
4. When mutter does an XSync() (explicitly or implicitly through some
other Xlib call), it will stop waiting for Xwayland to reply,
5. Xwayland waits for the XServerGrab() to be released by import,
6. "import" waits for a user input to release the XServerGrab(),
7. mutter is stuck waiting on Xwayland and does not process input
events...
To prevent this, re-route the GrabServer/UngrabServer requests and
pretend the grab works but actually does nothing at all for all clients
but the X11 window manager (which can still issue X11 server grabs, at
its own risks).

Clients should never need to do anything but check whether the extension

When the pointer leaves an X11 window, and enters a Wayland native

Exposing viewporter, wouldn't make sense here, and could mislead native

Xwayland does not change the actual XRANDR setup for real, it just
emulates the resolution changes using viewports in Wayland.
With a single output, if an X11 applications tries to change the CRTC
back to the native mode, RRCrtcSet() will simply ignore the request as
no actual change is induced by this.
Set the property "RANDR Emulation" on all Xwayland outputs to make sure
the optimizations in RRCrtcSet() get skipped and Xwayland can receive

The composite overlay window (COW) can be queried from any X11 client,
not just the X11 compositing manager.
If a client tries to get the composite overlay window, the Xserver will
map the window and block all pointer events (the window being mapped and
on top of the stack).
To avoid that issue, unset the "mapped" state of the composite overlay
window once realized when Xwayland is running rootless.
Note: All Xservers are actually affected by this issue, but with most
regular X servers, the compositing manager will take care of dealing
with the composite overlay window, and an X11 client using
GetOverlayWindow() won't break pointer events for all X11 clients.
Wayland compositors however usually run Xwayland rootless and have no

Xwayland may open a fair amount of file descriptors for passing Wayland

As a result, Xwayland may hit the (soft) limit of file descriptors
leading to a Wayland protocol error and the termination of Xwayland.
To mitigate that risk, raise the limit to the maximum (hard) limit of
file descriptors (unless of course the limit was set explicitly from the
command line with "-lf").

Currently, when given the choice, Xwayland will pick the GBM backend
over the EGLstream backend if both are available, unless the command
line option “-eglstream” is specified.
The NVIDIA proprietary driver had no support for GBM until driver series
495, but starting with the driver series 495, both can be used.
But there are other requirements with the rest of the stack, typically
Mesa, egl-wayland, libglvnd as documented in the NVIDIA driver.
So if the NVIDIA driver series 495 gets installed, Xwayland will pick
the GBM backend even if EGLstream is available and may fail to render
properly.
To avoid that issue, prefer EGLstream if EGLstream and all the Wayland
interfaces are available, and fallback to GBM automatically unless
“-eglstream” was specified.
With this, the compositor, given the choice, can decide which actual
backend Xwayland would use by advertising (or not) the Wayland
"wl_eglstream_controller" interface.
This change has no impact on compositors which do not have support for
EGLstream in the first place.

Before doing the VT_RELDISP, send a dbus message to logind, to

Additionally, currently Xwayland completely ignores any hardware

A better solution would be to make the default DPI stay as is and enable

and send the expected ConfigureNotify and RRScreenChangeNotify events
with the emulated size of the root window to the asking X11 client.
Note that the root window size does not actually change, as XRandR
emulation is achieved by scaling the client window using viewports in
Wayland, so this event is sort of misleading.
Also, because Xwayland is using viewports, emulating XRandR does not
reconfigure the outputs location, meaning that the actual size of the
root window which encompasses all the outputs together may not change
in a multi-monitor setup. To work around this limitation, when using an
emulated mode, we report the size of that emulated mode alone as the
root size for the configure notify event.

SimpleDRM 'devices' are a fallback device, and do not have a busid
so they are getting skipped. This will allow simpledrm to work
with the modesetting driver
The "sync crtc" is the crtc used to drive the display timing of a
drawable under DRI2 and DRI3/Present. If a drawable intersects
multiple video outputs, then normally the crtc is chosen which has
the largest intersection area with the drawable.
If multiple outputs / crtc's have exacty the same intersection
area then the crtc chosen was simply the first one with maximum
intersection. Iow. the choice was random, depending on plugging
order of displays.
This adds the ability to choose a preferred output in such a tie
situation. The RandR output marked as "primary output" is chosen
on such a tie.
This new behaviour and its implementation is consistent with other
video ddx drivers. See amdgpu-ddx, ati-ddx and nouveau-ddx for
reference. This commit is a straightforward port from amdgpu-ddx.

In a setup with both VRR capable and non-VRR capable displays,
it was so far inconsistent if the driver would allow use of
VRR support or not, as "is_connector_vrr_capable" was set to
whatever the capabilities of the last added drm output were.
Iow. the plugging order of monitors determined the outcome.
Fix this: Now if at least one display is VRR capable, the driver
will treat an X-Screen as capable for VRR, plugging order no
longer matters.
Tested with a dual-display setup with one VRR monitor and one
non-VRR monitor. This is also beneficial with the new Option
"AsyncFlipSecondaries".
When we are at it, also add some so far missing description of
the "VariableRefresh" driver option, copied from amdgpu-ddx.

A lut size of 4096 slots has been verified to work correctly,
as tested with amdgpu-kms. Intel Tigerlake Gen12 hw has a very
large GAMMA_LUT size of 262145 slots, but also issues with its
current GAMMA_LUT implementation, as of Linux 5.14.
Therefore we keep GAMMA_LUT off for large lut's. This currently
excludes Intel Icelake, Tigerlake and later.
This can be overriden via the "UseGammaLUT" boolean xorg.conf option
to force use of GAMMA_LUT on or off.

With the GBM backend becoming usable with different drivers such as
NVIDIA, set the GLVND vendor to the same value as the GBM backend name.
Mesa implementation however returns "drm" so we need to special case
this value - Basically, for anything other than "drm" we simply assume
that the GBM backend name is the same as the vendor.

Xwayland was passing GBM bos directly to
eglCreateImageKHR using the EGL_NATIVE_PIXMAP_KHR
target. Given the EGL GBM platform spec claims it
is invalid to create a EGLSurface from a native
pixmap on the GBM platform, implying there is no
mapping between GBM objects and EGL's concept of
native pixmaps, this seems a bit questionable.
This change modifies the bo import function to
extract all the required data from the bo and then
imports it as a dma-buf instead when the dma-buf +
modifiers path is available.

Xwayland's xwl_shm_create_pixmap() computes the size of the shared
memory pool to create using a size_t, yet the Wayland protocol uses an
integer for that size.
If the pool size becomes larger than INT32_MAX, we end up asking Wayland
to create a shared memory pool of negative size which in turn will raise
a protocol error which terminates the Wayland connection, and therefore
Xwayland.
Avoid that issue early by return a NULL pixmap in that case, which will
trigger a BadAlloc error, but leave Xwayland alive.

This reverts commit 617f591fc4.
The problem described in that commit exists, but the two
preceeding commits with improvements to the servers RandR
code should avoid the mentioned problems while allowing the
use of GAMMA_LUT's instead of legacy gamma lut.
Use of legacy gamma lut's is not a good fix, because it will reduce
color output precision of gpu's with more than 1024 GAMMA_LUT
slots, e.g., AMD, ARM MALI and KOMEDA with 4096 slot luts,
and some Mediathek parts with 512 slot luts. On KOMEDA, legacy
lut's are completely unsupported by the kms driver, so gamma
correction gets disabled.
The situation is especially bad on Intel Icelake and later:
Use of legacy gamma tables will cause the kms driver to switch
to hardware legacy lut's with 256 slots, 8 bit wide, without
interpolation. This way color output precision is restricted to
8 bpc and any deep color / HDR output (10 bpc, fp16, fixed point 16)
becomes impossible. The latest Intel gen gpu's would have worse
color precision than parts which are more than 10 years old.

The assumption in the upsampling code was that the crtc->gamma_size
size of the crtc's gamma table is a power of two. This is true for
almost all current driver + gpu combos at least on Linux, with typical
sizes of 256, 512, 1024 or 4096 slots.
However, Intel Gen-11 Icelake and later are outliers, as their gamma
table has 2^18 + 1 slots, very big and not a power of two!
Try to make upsampling behave at least reasonable: Replicate the
last gamma value to fill up remaining crtc->gamma_red/green/blue
slots, which would normally stay uninitialized. This is important,
because while the intel display driver does not actually use all
2^18+1 values passed as part of a GAMMA_LUT, it does need the
very last slot, which would not get initialized by the old code.
This should hopefully create reasonable behaviour with Icelake+
but is untested on the actual Intel hw due to lack of suitable
hw.

If randrp->palette_size is zero, the memcpy() path can read past the
end of the randr_crtc's gammaRed/Green/Blue tables if the hw crtc's
gamma_size is greater than the randr_crtc's gammaSize.
Avoid this by clamping the to-be-copied size to the smaller of both
sizes.
Note that during regular server startup, the memcpy() path is only
taken initially twice, but then a suitable palette is created for
use during a session. Therefore during an actual running X-Session,
the xf86RandR12CrtcComputeGamma() will be used, which makes sure that
data is properly up- or down-sampled for mismatching source and
target crtc gamma sizes.
This should avoid reading past randr_crtc gamma memory for gpu's
with big crtc->gamma_size, e.g., AMD/MALI/KOMEDA 4096 slots, or
Intel Icelake and later with 262145 slots.
Tested against modesetting-ddx and amdgpu-ddx under screen color
depth 24 (8 bpc) and 30 (10 bpc) to make sure that clamping happens
properly.
This is an alternative fix for the one attempted in commit
617f591fc4.

We turn this on if the GL underneath us can enable GL_FRAMEBUFFER_SRGB.
We do try to generate both capable and incapable configs, which is to
keep llvmpipe working until the client side gets smarter about its srgb
capabilities.
xwl_present_reset_timer checks if the pending flip is synchronous, so
we need to call it after adding the pending flip to the flip queue.

Rotation is broken for all drm drivers not providing hardware rotation
support. Drivers that give direct access to vram and not needing dirty
updates still work but only by accident. The problem is caused by
modesetting not sending the correct fb_id to drmModeDirtyFB() and
passing the damage rects in the rotated state and not as the crtc
expects them. This patch takes care of both problems.

There's no real benefit to using GLX, and the other DDXes are using EGL
already, so let's converge on EGL so we can concentrate the fixes in one
place.
We go to some effort to avoid being the thing that requires libX11 here.
We prefer EGL_EXT_platform_xcb over _x11, and if forced to use the
latter we'll ask the dynamic linker for XGetXCBConnection and
XOpenDisplay rather than link against xlib stuff ourselves. Xephyr is
now a pure XCB application if it can be.
