We'd previously take the copy path. If we were actually flipping (in
which case skipped frames are more likely to occur), we'd ping-pong
between a smaller and larger number of back buffers, and frame-rate
could vary / take a dip due to the buffer management overhead.
While I'm not sure this is actually possible to hit at this point, it
definitely will be with the next change.

Previously, we would always allocate 3 buffers for page flipping. But 2
buffers can suffice for clients which always wait for buffer swaps to
complete before starting a new frame.
Therefore, keep track of the maximum number of buffers separately from
the current number, and only bump the latter if both current buffers are
busy.

We can generate the XML if anybody actually queries it, but this reduces
the amount of work in driver setup and means that we'll be able to support
driconf option queries on Android without libexpat.
This updates the driconf interface struct version for i965, i915, and
radeon to use the new getXml entrypoint to call the on-demand xml
generation. Note that our loaders (egl, glx) implement the v2 function
interface and don't use .xml when that's set, and the X server doesn't use
this interface at all.

If the underlying X11 window gets destroyed, the event we're waiting
for may never be delivered, in which case xcb_wait_for_special_event
would hang indefinitely.
Solution:
1. Use xcb_poll_for_special_event to check if an event has arrived yet.
2. If not, Wait up to ~1s for XCB's file descriptor to become readable;
if it does, go back to step 1.
3. If the file descriptor didn't become readable, make a round-trip to
the X server to check that the window still exists. Go back to step
1 if it does, otherwise bail.
Also add an early bail-out when it's known that the window was
destroyed.

Enabling this option makes Intel Gen8-11 hardware load the 'iris'
driver by default instead of the older 'i965' driver.
Regardless of how this option is set, users can still override which
driver the loader selects via two methods. The first is to create a
~/.drirc or /etc/drirc file with the following snippet:
<driconf>
<device driver="loader" kernel_driver="i915">
<option name="dri_driver" value="i965" />
</device>
</driconf>
The other option is to set an environment variable:
export MESA_LOADER_DRIVER_OVERRIDE=i965
For now, "prefer_iris" defaults to i965 (the historical choice).
A separate future patch will change the default driver to iris.

The DDX driver can be notified of adaptive sync suitability by
flagging the application's window with the _VARIABLE_REFRESH property.
This property is set on the first swap the application performs
when adaptive_sync is set to true in the drirc.
It's performed here instead of when the loader is initialized for
two reasons:
(1) The window's drawable can be missing during loader init.
This can be observed during the Unigine Superposition benchmark.
(2) Adaptive sync will only be enabled closer to when the application
actually begins rendering.
If adaptive_sync is false then the _VARIABLE_REFRESH property
is deleted on loader init.
The property is only managed on the glx DRI3 backend for now. This
should cover most common applications and games on modern hardware.
Vulkan support can be implemented in a similar manner but would likely
require splitting the function out into a common helper function.

We only need to wait for the fence before drawing to a buffer, not

We don't need to wait before drawing to the fake front buffer, as front
buffer rendering by definition is allowed to produce artifacts.
Fixes hangs in some cases when re-using the fake front buffer, due to it
still being busy (i.e. in use for presentation).

Detect if the display (X-Server) gpu and Prime renderoffload gpu prefer
different channel ordering for color depth 30 formats ([X/A]BGR2101010
vs. [X/A]RGB2101010) and perform format conversion during the blitImage()
detiling op from tiled backbuffer -> linear buffer.
For this we need to find the visual (= red channel mask) for the
X-Drawable used to display on the server gpu. We use the same proven
logic for finding that visual as in commit "egl/x11: Handle both depth
30 formats for eglCreateImage()".
This is mostly to allow "NVidia Optimus" at depth 30, as Intel/AMD
gpu's prefer xRGB2101010 ordering, whereas NVidia gpu's prefer
xBGR2101010 ordering, so we can offload to nouveau without getting
funky colors.
Tested on Intel single gpu, NVidia single gpu, Intel + NVidia prime
offload with DRI3/Present.
Note: An unintended but pleasant surprise of this patch is that it also
seems to make the modesetting-ddx of server 1.20.0 work at depth 30
on nouveau, at least with unredirected "classic" X rendering, and
with redirected desktop compositing under XRender accel, and with OpenGL
compositing under GLX. Only X11 compositing via OpenGL + EGL still gives
funky colors. modesetting-ddx + glamor are not yet ready to deal with
nouveau's ABGR2101010 format, and treat it as ARGB2101010, also exposing
X-visuals with ARGB2101010 style channel masks. Seems somehow this triggers
the logic in this patch on modesetting-ddx + depth 30 + DRI3 buffer sharing
and does the "wrong" channel swizzling that then cancels out the "wrong"
swizzling of glamor and we end up with the proper pixel formatting in
the scanout buffer :). This so far tested on a NVA5 Tesla card under KDE5
Plasma as shipping with Ubuntu 16.04.4 LTS.

ARM SoCs usually have their DRM/KMS devices on the platform bus, so add
support for this bus in order to allow use of the DRI_PRIME environment
variable with those devices.
While at it, also support the host1x bus, which is effectively the same
but uses an additional layer in the bus hierarchy.
Note that it isn't enough to support the bus that has the rendering GPU
because the loader code will also try to construct an ID path tag for a
scanout-only device if it is the default that is being opened.
The ID path tag for a device can be obtained by running udevadm info on
the device node, as shown in this example on NVIDIA Tegra:
$ udevadm info /dev/dri/card0 | grep ID_PATH_TAG
E: ID_PATH_TAG=platform-50000000_host1x
The corresponding OF_FULLNAME property, from which the ID_PATH_TAG is
constructed, can be found in the sysfs "uevent" attribute for the card0
device's parent:
$ grep OF_FULLNAME /sys/devices/platform/50000000.host1x/drm/uevent
OF_FULLNAME=/host1x@50000000
Similarily, /dev/dri/card1 corresponds to the GPU:
$ udevadm info /dev/dri/card1 | grep ID_PATH_TAG
E: ID_PATH_TAG=platform-57000000_gpu
and:
$ grep OF_FULLNAME /sys/devices/platform/57000000.gpu/uevent

We were using a sequence counter value to wait for a specific NotifyMSC
event. However, we can receive events from other clients as well, which
may already be using higher sequence numbers than us. In that case, we
could stop processing after an event from another client, which could
have been received significantly earlier. This would have multiple
undesirable effects:
* The computed MSC and UST values would be lower than they should be
* We could leave a growing number of NotifyMSC events from ourselves and
other clients in XCB's special event queue
I ran into this with Firefox and Thunderbird, whose VSync threads both
seem to use the same window. The result was sluggish screen updates and
growing memory consumption in one of them.
Fix this by checking the XCB sequence number and MSC value of NotifyMSC
events, instead of using our own sequence number.

* Use the Present event ID for the sequence parameter of the
PresentNotifyMSC request, as another safeguard against processing
events from other clients

Upon reception of an event that lowered the number of active back buffers,
the code would immediately try to free all back buffers with an id equal to or
higher than the new number of active back buffers.
However, that could lead to an active or to-be-active back buffer being freed,
since the old number of back buffers was used when obtaining an idle back
buffer for use.
This lead to crashes when lowering the number of active back buffers by
transitioning from page-flipping to non-page-flipping presents.
Fix this by computing the number of active back buffers only when trying to
obtain a new back buffer.

It turned out that with recent changes that call into dri3 from glFinish(),
it appears like different thread end up waiting for X events simultaneously,
causing deadlocks since they steal events from eachoter and update the dri3
counters behind eachothers backs.
This patch intends to improve on that. It allows at most one thread at a
time to wait on events for a single drawable. If another thread intends to
do the same, it's put to sleep until the first thread finishes waiting, and
then it rechecks counters and optionally retries the waiting. Threads that
poll for X events never pulls X events off the event queue if there are
other threads waiting for events on that drawable. Counters in the
dri3 drawable structure are protected by a mutex. Finally, the mutex we
introduce is never held while waiting for the X server to avoid
unnecessary stalls.
This does not make dri3 drawables completely thread-safe but at least it's a
first step.
