This is a modified version of a patch we've been carry-ing in Fedora and
RHEL for years now. This patch automatically adds secondary GPUs to the
master as output sink / offload source making e.g. the use of
slave-outputs just work, with requiring the user to manually run
"xrandr --setprovideroutputsource" before he can hookup an external
monitor to his hybrid graphics laptop.
There is one problem with this patch, which is why it was not upstreamed
before. What to do when a secondary GPU gets detected really is a policy
decission (e.g. one may want to autobind PCI GPUs but not USB ones) and
as such should be under control of the Desktop Environment.
Unconditionally adding autobinding support to the xserver will result
in races between the DE dealing with the hotplug of a secondary GPU
and the server itself dealing with it.
However we've waited for years for any Desktop Environments to actually
start doing some sort of autoconfiguration of secondary GPUs and there
is still not a single DE dealing with this, so I believe that it is
time to upstream this now.
To avoid potential future problems if any DEs get support for doing
secondary GPU configuration themselves, the new autobind functionality
is made optional. Since no DEs currently support doing this themselves it
is enabled by default. When DEs grow support for doing this themselves
they can disable the servers autobinding through the servers cmdline or a
xorg.conf snippet.

The purpose of rrCheckPixmapBounding() is to make sure that the fb is large
enough to accommodate the region scanned out by a GPU screen. Currently, however,
it will actually shrink the fb if it's larger than it needs to be.
This is a problem when combining PRIME output slaving with arbitrary transforms
with xrandr.
Although arbitrary transforms are not supposed to constrain the size of the fb
(https://lists.freedesktop.org/archives/xorg-devel/2018-January/055563.html),
xrandr will use RRSetScreenSize to resize the desktop to accommodate scaling
transforms, e.g. scaling a 1920x1080 display to 3840x2160 will result in a
desktop size of 3840x2160.
In the case of PRIME, rrCheckPixmapBounding() will be called after
RRSetScreenSize() and it will resize the fb back down to what it would be
without the scaling transform, e.g. 1920x1080. This represents divergence in
behavior between PRIME and non-PRIME outputs.
I had originally made rrCheckPixmapBounding() account for arbitrary transforms,
but realized that the fb being large enough to accommodate arbitrary transforms
is not a hard requirement enforced in the server. Instead, this change simply
makes it so that rrCheckPixmapBounding() will only resize the fb to be larger
than it already is, preventing it from stepping on prior requests to increase
the size of the fb.

Instead of having every video driver loop over any pending leases to
free them during CloseScreen, do this up in the DIX layer by
terminating leases when a leased CRTC or Output is destroyed and
(just to make sure), also terminating leases in RRCloseScreen. The
latter should "never" get invoked as any lease should be associated
with a resource which was destroyed.
This is required as by the time the driver's CloseScreen function is
invoked, we've already freed all of the DIX randr structures and no
longer have any way to reference the leases

randr: Add RRConstrainCursorHarder
introduced a regression as it ignored the effect of panning and
transforms upon the crtc bounds. The result was that the cursor would be
constrained to the visible area even though the panning arena was much
bigger, or the cursor was constrained to a region that did not even
match the visible area when the output was transformed or reflected.
This supercedes the hack introduced by

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
active on our screen. Just tell the kernel to turn it off.
v6: Add meson build infrastructure

ProcRRSetScreenSize() does bounds checking to ensure that none of the CRTCs have
a viewport that extends beyond the new screen size. In doing so, it accounts for
if the CRTC is rotated 90 or 270 degrees, swapping width and height.
However, it does so by testing if crtc->rotation is equal to RR_Rotate_90 or
RR_Rotate_270. crtc->rotation is a bit mask, and it includes reflection as well
as rotation. If a CRTC is reflected as well as rotated, it will incorrectly fail
this test, resulting in incorrect dimensions being used to verify the validity
of the new screen size. In some cases, this can cause valid uses of
ProcRRSetScreenSize() to fail with BadMatch.
This patch fixes the issue by testing that the bits RR_Rotate_90 or
RR_Rotate_270 are set, rather than testing for equality.

When the last crtc (resp. output) is destroyed, the rrScrPriv crtcs
(resp. outputs) fields do not get cleared, which can lead to a situation
where the private's numCrtcs (resp. numOutputs) field is zero, but the
associated memory is still allocated. Just checking if numCrtcs (resp.
numOutputs) is zero is thus not a good criteria to determine whetehr to
use a realloc or a malloc.
Since crtcs (resp. outputs) are NULL-initialized anyway, relying on
numCrtcs (resp. numOutputs) is actually unnecessary, because
reallocation of a NULL ptr is equivalent to a malloc anyway.
Therefore, just use realloc() unconditionally, and ensure that the
fields are properly initialized.

The purpose of rrCheckPixmapBounding is to make sure that the
screen_pixmap is *large* enough for the slave-output which crtc is
being configured.
However until now rrCheckPixmapBounding would also shrink the
screen_pixmap in certain scenarios leading to various problems.
For example: Take a laptop with its internalscreen on a slave-output and
currently disabled and an external monitor at 1920x1080+0+0.
Now lets say that we want to drive the external monitor at its native
resolution of 2560x1440 and have the internal screen mirror the top left
part of the external monitor, so we run:
$ xrandr --output eDP --mode 1920x1080 --pos 0x0 --output HDMI \
--mode 2560x1440 --pos 0x0
Here xrandr utility first calls RRSetScreenSize to 2560x1440, then it
calls RRSetCrtc 1920x1080+0+0 on the eDP, since this is a slave output,
rrCheckPixmapBounding gets called and resizes the screen_pixmap to
1920x1080, undoing the RRSetScreenSize. Then RRSetCrtc 2560x1440+0+0
gets called on the HDMI, depending on crtc->transforms this will
either result in a BadValue error from ProcRRSetCrtcConfig; or
it will succeed, but the monitor ends up running at 2560x1440
while showing a 1920x1080 screen_pixmap + black borders on the right
and bottom. Neither of which is what we want.
This commit removes the troublesome shrinking behavior, fixing this.
Note:
1) One could argue that this will leave us with a too large screen_pixmap
in some cases, but rrCheckPixmapBounding only gets called for slave
outputs, so xrandr clients already must manually shrink the screen_pixmap
after disabling crtcs in normal setups.
2) An alternative approach would be to also call rrCheckPixmapBounding
on RRSetCrtc on normal (non-slave) outputs, but that would result in
2 unnecessary resizes of the screen_pixmap in the above example, which
seems undesirable.

The purpose of rrCheckPixmapBounding is to make sure that the
screen_pixmap is large enough for the slave-output which crtc is
being configured.
This should include crtc->x and crtc->y, otherwise the crtc might
still end up scanning out an area outside of the screen-pixmap.
For example: Take a laptop with an external monitor on a slave-output at
1920x1080+0+0 and its internal-screen at 3840x2160+1920+0 and in
gnome-settings-daemon move the external monitor to be on the ri ght of
the internal screen rather then on the left. First g-s-d will do a
RRSetScreenSize to 5760*2160 (which is a nop), then it calls RRSetCrtc
to move the slave output to 1920x1080+3840+0, since this is a slave
output, rrCheckPixmapBounding gets called, since the 2 crtcs now overlap
the code before this commit would shrinks the screen_pixmap to 3180*2160.
Then g-s-d calls RRSetCrtc to move the internal screen to 3180*2160+0+0.
And we end up with the slave-output configured to scan-out an area
which completely falls outside of the screen-pixmap (and end up with
a black display on the external monitor).
This commit fixes this by not substracting the x1 and y1 coordinates
of the union-ed region when determining the new screen_pixmap size.

Before this commit crtc_bounds() did not take reflection into account,
when using reflection with 0 / 180 degree rotation this was not an
issue because of the default in the switch-case doing the right thing.
But when using 90 / 270 degree rotation we would also end up in the
default which is wrong in this case. This would lead to the cursor
being constrained to a height x height area of the monitor.
This commit masks out the reflection bits for the switch-case,
making crtc_bounds return the correct bounds and fixing the
problematic cursor constraining.

Adds an output parameter to disable PRIME synchronization.
Output parameter is created when the user calls 'xrandr

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.

Refactor to use rrEnableSharedPixmapFlipping() as a substitute for
rrCrtcSetScanoutPixmap() in the flipping case.

Adds typedefs for (*RRStartFlippingPixmapTrackingProcPtr),
(*RREnableSharedPixmapFlippingProcPtr),
and (*RRDisableSharedPixmapFlippingProcPtr) in randrstr.h.
Adds typedefs for (*PresentSharedPixmapProcPtr),
(*SharedPixmapNotifyDamageProcPtr),
(*RequestSharedPixmapNotifyDamageProcPtr), and
(*StopFlippingPixmapTrackingProcPtr) in scrnintstr.h.
Adds RR(Enable/Disable)SharedPixmapFlipping, and
RRStartFlippingPixmapTracking to rrScrnPrivRec.
Adds StopFlippingPixmapTracking, PresentSharedPixmap,
SharedPixmapNotifyDamage, and RequestSharedPixmapNotifyDamage to ScreenRec.
rrScrnPrivRec used for functions that use RandR-private data types, and
ScreenRec used for the rest.
RREnableSharedPixmapFlipping will allow the sink driver to setup for
flipping between two shared pixmaps.
RRDisableSharedPixmapFlipping will allow the sink driver to do teardown
associated with flipping between two shared pixmaps.
(RRStart/Stop)FlippingPixmapTracking are merely the double-buffered
equivalents of (Start/Stop)PixmapTracking, allowing the source driver to do
whatever setup and teardown necessary for presenting on the two shared
pixmaps.
PresentSharedPixmap is a function exposed by the source driver for the X
server or sink driver to call to request a present on a given shared
pixmap. This way, presents can be driven by the sink's vblank instead of a
timer or similar mechanism.
SharedPixmapNotifyDamage and RequestSharedPixmapNotifyDamage are OPTIONAL
(even for double-buffered PRIME) functions exposed by the sink driver and
the source driver, respectively. By calling
master->RequestSharedPixmapNotifyDamage(ppix), the sink driver can request
for the source driver to call slave->SharedPixmapNotifyDamage(ppix) in
response to damage on the master screen pixmap tracked by ppix.
v1: Initial commit
v2: Rename PresentTrackedFlippingPixmap to PresentSharedPixmap
Add SharedPixmapNotifyDamage / RequestSharedPixmapNotifyDamage
v3: Add RRCrtcPtr as a parameter to StartFlippingPixmapTracking
Move functions that use RandR-private data types to rrScrnPrivRec.

In prime configurations master's last set time may not be latest
and greatest, adjust it with slaves last set time, pick up greatest
one. Otherwise xserver may end with events which has
lastSetTime < lastConfigTime even if that's not
the case and confuse xrandr client.

A single provider can be both a offload and source slave at the same time,
the use of seperate lists breaks in this case e.g. :
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 0 name:modesetting
Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 0 name:modesetting
xrandr --setprovideroutputsource 1 0x7b
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:modesetting
Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 1 name:modesetting
xrandr --setprovideroffloadsink 1 0x7b
xrandr --listproviders
Providers: number : 3
Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 2 name:modesetting
Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting
Provider 2: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting
Not good. The problem is that the provider with id 0x46 now is on both
the output_slave_list and the offload_slave_list of the master screen.
This commit fixes this by unifying all 3 lists into a single slaves list.
Note that this does change the struct _Screen definition, so this is an ABI
break. I do not expect any of the drivers to actually use the removed / changed
fields so a recompile should suffice.

This is an ABI break, in that we now pass NULL to a function that hasn't
accepted it before.
Alex Goins had a different patch for this but it wasn't symmetrical, it
freed something in a very different place than it allocated it, this
attempts to retain symmetry in the releasing of the backing bo.
v2: use a new toplevel API, though it still passes NULL to something
that wasn't expecting it.
v3: pass -1 instead of 0.

Update currentTime in dispatch loop
Unfortunately this is equivalent to calling GetTimeInMillis() once per
request. In the absolute best case (as on Linux) you're only hitting the
vDSO; on other platforms that's a syscall. Either way it puts a pretty
hard ceiling on request throughput.
Instead, push the call down to the requests that need it; basically,
grab processing and event generation.

The old version of rrCreateSharedPixmap(), in addition to actually creating
a shared pixmap with scanout, also set up pixmap tracking on the source
driver.
I will be needing to create multiple shared pixmaps for PRIME double
buffering, so factor the part that does shared pixmap creation into its own
function, the new rrCreateSharedPixmap(). Rename the old
rrCreateSharedPixmap() to rrSetupPixmapSharing(), a function that
replicates the old functionality of rrCreateSharedPixmap() using the new
rrCreateSharedPixmap().

Shared pixmap destruction is done by unrefing the master pixmap twice: once
for the original reference, and once for the reference implicitly added by
PixmapShareToSlave. Then, unrefing the slave pixmap once.
When I add PRIME double buffering and synchronization, I will need to do
this in multiple places. To avoid duplication of code and comments
explaining it everywhere, factor it out into its own function and use that
in place of where it was before.

We only set changes on the main protocol screen as, for example
in RRSetChanged() and RRTellChanged(), therefore we should follow
the same logic when reporting that an output changed in
RROutputChanged().
This means that RRTellChanged() will then update the relevant
timestamps also when events come from gpu screens.

As we define sizeFits based on whether a CRTC is active, and skip trying
to redirect the scanout on a disable pipe, we then attempt to undo it
later and fail because crtc->scanout_pixmap != DRI2_Pixmap and
!sizeFits. Paper over this failure by skipping unredirected CRTC when
disabling.
