This adds support for RandR CRTC/Output leases through the modesetting
driver, creating a lease using new kernel infrastructure and returning
that to a client through an fd which will have access to only those
resources.
v2: Restore CRTC mode when leases terminate
When a lease terminates for a crtc we have saved data for, go
ahead and restore the saved mode.
v3: Report RR_Rotate_0 rotations for leased crtcs.
Ignore leased CRTCs when selecting screen size.
Stop leasing encoders, the kernel doesn't do that anymore.
Turn off crtc->enabled while leased so that modesetting
ignores them.
Check lease status before calling any driver mode functions
When starting a lease, mark leased CRTCs as disabled and hide
their cursors. Also, check to see if there are other
non-leased CRTCs which are driving leased Outputs and mark
them as disabled as well. Sometimes an application will lease
an idle crtc instead of the one already associated with the
leased output.
When terminating a lease, reset any CRTCs which are driving
outputs that are no longer leased so that they start working
again.
This required splitting the DIX level lease termination code
into two pieces, one to remove the lease from the system
(RRLeaseTerminated) and a new function that frees the lease
data structure (RRLeaseFree).
v4: Report RR_Rotate_0 rotation for leased crtcs.
v5: Terminate all leases on server reset.
Leases hang around after the associated client exits so that
the client doesn't need to occupy an X server client slot and
consume a file descriptor once it has gotten the output
resources necessary.
Any leases still hanging around when the X server resets or
shuts down need to be cleaned up by calling the kernel to
terminate the lease and freeing any DIX structures.
Note that we cannot simply use the existing
drmmode_terminate_lease function on each lease as that wants
to also reset the video mode, and during server shut down that
modesetting: Validate leases on VT enter
The kernel doesn't allow any master ioctls to run when another
VT is active, including simple things like listing the active
leases. To deal with that, we check the list of leases
whenever the X server VT is activated.
xfree86: hide disabled cursors when resetting after lease termination
The lessee may well have played with cursors and left one

The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.

Now that we can actually configure all of the directories xkb uses for
finding things, we can (finally, but only with meson) finally make it so
that with the correct meson configuration the Xserver will "just work"
without any additional changes to the installation prefix after
building.
For the people like me who have since scripted this part out of their
build process and forgotten about it, building and installing the X
server into a non-standard prefix has always required the following (or
something else that makes sure that X has a valid xkbcomp configuration)
commands be run right after doing the installation:
# start in root of prefix you installed X to
mkdir -pv share/X11/xkb/rules
ln -s /usr/share/X11/xkb/rules/evdev share/X11/xkb/rules/
rm -f bin/xkbcomp
ln -s /usr/bin/xkbcomp bin/
The one last piece of getting rid of this post-install junk is making
sure that we can control the directory that X uses for finding the
xkbcomp binary from meson so we can point it at the system provided
xkbcomp (/usr/bin/xkbcomp or similar). So, this patch adds a
configuration option for controlling this called xkb_bin_dir.

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

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.

A new --with-fallback-input-driver=foo option allows selecting a
fallback driver for the server if the driver configured for the device
is not found. Note that this only applies when the device has a driver
assigned and that module fails to load, devices without a driver are
ignored as usual.
This avoids the situation where a configuration assigns e.g. the
synaptics driver but that driver is not available on the system,
resulting in a dead device. A fallback driver can at least provides some
functionality.
This becomes more important as we move towards making other driver true
leaf nodes that can be installed/uninstalled as requested. Specifically,
wacom and synaptics, a config that assigns either driver should be
viable even when the driver itself is not (yet) installed on the system.
It is up to the distributions to make sure that the fallback driver is
always installed. The fallback driver can be disabled with
--without-fallback-input-driver and is disabled by default on non-Linux
systems because we don't have generic drivers on those platforms.
Default driver on Linux is libinput, evdev is the only other serious

By default the X server will try CLOCK_MONOTONIC_COARSE before

issues since it may happen that a timestamp from CLOCK_MONOTONIC
retrieved before a sending an X request will still be "later" than the
timestamp the X server than gets after receiving the request, due to the
fact that CLOCK_MONOTONIC_COARSE has a lower resolution.
To avoid these issues, make Xwayland always use CLOCK_MONOTONIC, so
that it becomes possible for Wayland compositor only supporting

When NumLock is on and a new keymap is applied, the next modifier state
change will turn off that LED (but leave the state enabled). The cause
for this is a bit convoluted:
* the SLI explicitState is copied from the current state in
ProcXkbGetKbdByName. Thus, if NumLock is on, that state is 0x2.
* on the next modifier key press (e.g. Shift), XkbApplyState() calls into
XkbUpdateIndicators() -> XkbUpdateLedAutoState() to update SLIs (if any)
for the currently changed modifier. But it does so with a mask only for
the changed modifier (i.e. for Shift).
* XkbUpdateLedAutoState() calculates the state based on this mask and
ends up with 0 because we don't have a Shift LED and we masked out the
others.
* XkbUpdateLedAutoState() compares that state with the previous state
(which is still 0x2) and then proceeds to turn the LED off
This doesn't happen in the normal case because either the mask
encompasses all modifiers or the state matches of the masked-out
modifiers matches the old state.
Avoid this issue by forcing an SLI update after changing the keymap.
This updates the sli->effectiveState and thus restores everything to
happy working order.

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work

One of the lacking features with output offloading was
that screen rotation didn't work at all.
This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.
When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.
v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.
This breaks ABI in two places.

We need this for doing USB offload scenarios using glamor
and modesetting driver.
unfortunately only gbm in mesa 10.6 has support for the
linear API.
v1.1: fix bad define
v2: update the configure.ac test as per amdgpu. (Michel)
set linear bos to external to avoid cache. (Eric)

I doubt anyone builds with this turned off or has done for a long
time.
It helps my eyes bleed slightly less when reading the code, I've left
the define in place as some drivers use it.

If the X server is started without a '-auth' argument, then
it gets started wide open to all local users on the system.
This isn't a great default access model, but changing it in
Xorg at this point would break backward compatibility.
Xwayland, on the other hand is new, and much more targeted
in scope. It could, in theory, be changed to allow the much
more secure default of a "user who started X server can connect
clients to that server."
This commit paves the way for that change, by adding a mechanism
for DDXs to opt-in to that behavior. They merely need to call
LocalAccessScopeUser()
in their init functions.
A subsequent commit will add that call for Xwayland.

Allows a mask to carry both accelerated and unaccelerated motion at the same
time.
This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
and DGA rely on device-specific unaccelerated data.
To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.
Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.
The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.
