present_restore_screen_pixmap's work doesn't need to be done several
times for the same pending flip.
Fixes a crash if the X server quits while a flip is pending, in which
case present_set_abort_flip may be called several times, including when
screen->root is already cleared to NULL.

Instead of breaking the former when the driver supports the latter,
hook them up so that the hardware LUTs reflect the combination of the
current colourmap and gamma states. I.e. combine the colourmap, the
global gamma value/ramp and the RandR 1.2 per-CRTC gamma ramps into one
combined LUT per CRTC.

This would normally return the same values the core RandR code passed to
xf86RandR12CrtcSetGamma before, which is rather pointless. The only
possible exception would be if a driver tried initializing
crtc->gamma_red/green/blue to reflect the hardware LUT state on startup,
but that can't work correctly if whatever set the LUT before the server
started was running at a different depth.
Even the pointless round-trip case will no longer work with the
following change.

Do all timer stuff before blocking, avoiding a bunch of duplicate code
and merge common code in WaitForSomething.
The WaitForSomething changes need a bit of explanation to show that
the new code is effectively equivalent to the old. Eliding error
checking and trivial bits we've got:
Before:
if (ready clients)
timeout = 0
else
compute timeout
i = poll
if (i <= 0) {
if (ready clients)
return TRUE;
if (input)
return FALSE;
if (any ready timers) {
run timers
return FALSE;
}
} else {
if (input)
return FALSE;
if (any ready timers) {
run timers
return FALSE;
}
if (ready clients)
return TRUE;
}
After:
if (ready clients)
timeout = 0;
else
compute timeout
run_timers
poll
if (input)
return FALSE;
if (ready clients)
return TRUE;
The old code would return TRUE if there were ready clients and input
pending. Dispatch would then schedule that ready client, but before
processing any requests, it would notice that there was input pending
and go process it. The new code just checks for input first, which is
effectively the same.
If the poll timed out and there weren't clients ready, then timers
would get run.
If the poll didn't time out, then timers would get run, even if there
were clients now ready. Now, if the timeout interval was zero, that
means that the timers must have been ready *before* poll was
invoked. In this case, we should simply run the timers before calling
poll -- no sense calling poll just to discard any data that it
generates.
If the timeout interval was non-zero, and poll didn't timeout, then
either there aren't any timers to run, or we got a surprise and hit a
timer exactly as a client became ready to run. This is the one case
where the new code is different from the old; the new code delays the
timer call until the next time WaitForSomething is called.

It is a modest performance improvement (2.7% on Intel), with the
significant downside that it keeps extra pixmap contents laying around
for 1000 BlockHandlers without the ability for the system to purge
them when under memory pressure, and tiled renderers don't know that
we could avoid reading their current contents when beginning to render
again. We could use the FB invalidate functions, but they aren't
always available, aren't hooked up well in Mesa, and would eat into
the performance gains of having the cache.

Adds an output parameter to disable PRIME synchronization.
Output parameter is created when the user calls 'xrandr
--setprovideroutputsource <sink> <source>' to prevent polluting output
parameters of non-PRIME configurations.
Defaults to on, so if the user wants PRIME synchronization they don't need
to do anything.
If the user wishes to disable PRIME synchronization when they first set up
PRIME, they can run 'xrandr --output <output> --set "PRIME Synchronization"
0' after running 'xrandr --setprovideroutputsource <sink> <source>', but
before 'xrandr --auto'.
If the user wishes to enable or disable PRIME synchronization after PRIME has
already been set up, they can run 'xrandr --output <output> --set "PRIME
Synchronization" <0 or 1>' at any time, xrandr will trigger a modeset, which
will tear down and setup PRIME in the configuration they requested on CRTCs
associated with that output.
randrstr.h:
Add central definition of the output property name.
rrcrtc.c:
Add function rrGetPixmapSharingSyncProp() to query the status of the
output property.
Add function rrSetPixmapSharingSyncProp() to set the output property.

Changes rrSetupPixmapSharing() to only report an error if falling back
to single buffering when the user requested synchronization.
Change RRCrtcSet() to use rrPixmapSharingSyncProp() to query the status
of the output property and feed it into rrSetupPixmapSharing() using
the 'sync' parameter.
rrprovider.c:
Add RR(Init/Fini)PrimeSyncProps(), functions to create and destroy the
PRIME synchronization output property.
Add a call to RRInitPrimeSyncProps() in
ProcRRSetProviderOutputSource(), such that the output property is
created when the user requests PRIME.
