in the dri2_format_table, but had been hidden from outside view,
for lack of an official DRM fourcc. Since its fourcc has now been

e9c3dbd046 added PIPE_BIND_DRI_PRIME but it was only set when
importing a prime buffer.
This commit adds handling of this flag in the other codepath = the
one where the prime buffer is allocated by the render GPU.
With this change PIPE_BIND_DRI_PRIME is still only set for the
render GPU - the display GPU will never see this flag; a future
commit will rename it.

This fixes SPECVIEWPERF13 creo test case hang:
1. Client: send present pixmap request (serial=1) when swap_interval==1
and increase send_sbc=1
2. Server: pend the request before vblank arrives
3. Client: set swap_interval=0 (so set XCB_PRESENT_OPTION_ASYNC),
send another present pixmap request (serial=2), increase send_sbc=2
4. Server: handle the async request immediately and send complete event
(serial=2)
5. Client: handle the event and set recv_sbc=event->serial=2
6. Server: vblank arrives so handle pending request and send complete
event (serial=1)
7. Client: handle the event and set recv_sbc=event->serial=1
8. Client: someone call loader_dri3_swapbuffer_barrier() and waiting
on recv_sbc==send_sbc, but no one will set recv_sbc=2 again
So basically it's caused by swap happens out of order. This commit
fixes the problem by waiting on the pending sync swaps all done when
switching to async mode, so move 6&7 before 3.

For DRI_PRIME setup where the dGPU -> iGPU copy can happen asynchronously,
we need to ensure that we're not continuously reusing the same back buffer.
The existing code relies on XCB_PRESENT_EVENT_IDLE_NOTIFY to decide if
a buffer is busy or idle. If this event is received before the hardware
is done using the buffer, then it will reuse the same buffer and introduce
a dependency between the copy and the next frame.
This commit mitigates this by trying to allocate a different back buffer
when called from dri3_get_buffer (not from dri3_find_back_alloc, because it
seems that it expects dri3_get_buffer - see 0cc4c7e33e).
An alternative would be to query the busy-ness using is_resource_busy
but this complicates the code to achieve the same result.
One affected app is Unigine Superposition, and this change improves the
score by 0% - 5% depending on the settings.
This behavior is enabled if PIPE_CAP_PREFER_BACK_BUFFER_REUSE is 0.

With swap interval 0, i.e. sync-to-vblank disabled.
This can be necessary for unthrottled drawing with Xwayland:
1) One buffer can be scanned out
2) One buffer can be pending in the kernel for a page flip
3) One buffer can be pending in the Wayland compositor
Therefore, with 3 buffers, the frame-rate could be capped much lower
than the throughput the GPU is capable of, in the worst case at the
Wayland compositor refresh rate.
(The native Wayland EGL backend always uses up to 4 buffers)
Leave the maximum number of buffers at 3 for swap interval != 0, it's
sufficient in that case to always be able to queue one frame ahead of
time.

between a smaller and larger number of back buffers, and frame-rate

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

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.
