Xaver Hugl 7759743c63 randr: add new interface to allow delaying lease responses
Add a new interface to _rrScrPriv to make it possible for the server to
delay answering a lease request, at the cost of blocking the client. This
is needed for implementing drm-lease-v1, as the Wayland protocol has no
defined time table for responding to lease requests.

Mario Kleiner f467f85ca1 Fix RandR leasing for more than 1 simultaneously active lease.
Due to a switched order of parameters in the xorg_list_add()
call inside ProcRRCreateLease(), adding a new lease for RandR
output leasing does not actually add the new RRLeasePtr lease
record to the list of existing leases for a X-Screen, but instead
replaces the existing list with a new list that has the new lease
as the only element, and probably leaks a bit of memory.

Therefore the server "forgets" all active leases for a screen,
except for the last added lease. If multiple leases are created
in a session, then destruction of all leases but the last one
will fail in many cases, e.g., during server shutdown in
RRCloseScreen(), or resource destruction, e.g., in
RRCrtcDestroyResource().

Most importantly, it fails if a client simply close(fd)'es the
DRM master descriptor to release a lease, quits, gets killed or
crashes. In this case the kernel will destroy the lease and shut
down the display output, then send a lease event via udev to the
ddx, which e.g., in the modesetting-ddx will trigger a call to
drmmode_validate_leases().

That function is supposed to detect the released lease and tell
the server to terminate the lease on the server side as well,
via xf86CrtcLeaseTerminated(), but this doesn't happen for all
the leases the server has forgotten. The end result is a dead
video output, as the server won't reinitialize the crtc's
corresponding to the terminated but forgotten lease.

This bug was observed when using the amdvlk AMD OSS Vulkan
driver and trying to lease multiple VKDisplay's, and also
under Mesa radv, as both Mesa Vulkan/WSI/Display and amdvlk
terminate leases by simply close()ing the lease fd, not by
sending explicit RandR protocol requests to free leases.

Leasing worked, but ending a session with multiple active
leases ended in a lot of unpleasant darkness.

Fixing the wrong argument order to xorg_list_add() fixes the
problem. Tested on single-X-Screen and dual-X-Screen setups,
with one, two or three active leases.

Please merge this for the upcoming server 21.1 branch.
Merging into server 1.20 would also make a lot of sense.

Michel Dänzer a6d178b6af randr: Bail from RRTellChanged if there's no root window yet
This can happen if RRTellChanged is called during initialization.

Continuing in that case makes no sense conceptually:

* Any event sent over the wire requires a corresponding window.
* No root window probably means there can't be any clients which could
  receive the events.

In practice, it would result in a crash down the road due to
dereferencing the NULL ScreenRec::root pointer.

Pekka Paalanen bfb36a5806 randr: auto-bind of GPU is a config change
When a GPU is auto-bound adding more outputs to a screen, that needs to count
as a configuration change on that screen so that a WM listening for
RRScreenChangeNotify gets notified and handles it as a hotplug. This is
particularly for cases where the outputs are already connected. Otherwise
nothing might happen.

Issue #909 describes a real world case where plugging in a DisplayLink dock
with a monitor already connected is sometimes left inactive by GNOME. That
issue is a race, and requires adding a sleep(5); as the first thing in
NewGPUDeviceRequest() to reproduce reliably. With the sleep, the monitor in the
dock will never activate automatically. Add this fix over the sleep, and the
issue is gone.

This fix was originally developed on a branch replicating Ubuntu 19.04 patch
set based on xserver 1.20.4. Testing on master branch was impossible due to
xorg/xserver#910.

Dave Airlie 078277e4d9 xf86: autobind GPUs to the screen
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.

Alex Goins a90f33721e randr: rrCheckPixmapBounding should only increase screen size
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.

Keith Packard 1ef7aed3e2 During reset/shutdown, clean up leases in DIX instead of each driver
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

Keith Packard e4e3447603 Add RandR leases with modesetting driver support [v6]
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

Alex Goins 6b26a7bda9 randr: Fix rotation check in ProcRRSetScreenSize()
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.

Giuseppe Bilotta 16381d186e randr: always realloc crtcs and outputs
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.

Hans de Goede a46afee84d randr: rrCheckPixmapBounding: do not shrink the screen_pixmap
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.

Hans de Goede 3b624aa9a9 randr: rrCheckPixmapBounding: Do not substract crtc non 0 x,y from screen size
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

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,

agoins df8e86931e randr: Add ability to turn PRIME sync off
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.

    Add 'sync' parameter to rrSetupPixmapSharing(), which when false will
    use single buffering even if the required ABI functions are supported.
    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.

    Add a call to RRFiniPrimeSyncProps() in RRProviderDestroy().

    Changes RRCrtcDetachScanoutPixmap() to properly clean up in the case of

    Changes RRReplaceScanoutPixmap() to fail if we are using double buffering,
    as it would need a second ppix parameter to function with double buffering,
    and AFAICT no driver I've implemented double buffered source support in uses
    RRReplaceScanoutPixmap().

randrstr.h:
    Adds scanout_pixmap_back to struct _rrCrtc to facilitate PRIME
    double buffering.

xf86Crtc.h:
    Adds current_scanout_back to _xf86Crtc to facilitate detection
    of changes to it in xf86RandR12CrtcSet().

xf86RandR12.c:
    Changes xf86RandR12CrtcSet() to detect changes in

Adds typedefs for (*RRStartFlippingPixmapTrackingProcPtr),

Adds typedefs for (*PresentSharedPixmapProcPtr),
(*SharedPixmapNotifyDamageProcPtr),

(*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.

xrandr --setprovideroffloadsink 1 0x7b

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.

Unfortunately this is equivalent to calling GetTimeInMillis() once per

hard ceiling on request throughput.

Instead, push the call down to the requests that need it; basically,

agoins cf5d6414e0 randr: Factor out shared pixmap destruction
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

the same logic when reporting that an output changed in

This means that RRTellChanged() will then update the relevant

Dave Airlie 90db5edf11 prime: add rotation support for offloaded outputs (v2)
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.

Prevent RRXinerama from activating if PseudoramiX is, so we don't get XINERAMA
listed twice in the list of extensions.  I think this is otherwise benign, as
the PseudoramiX XINERAMA gets registered first and thus handles all requests.

Perhaps AddExtension() ought to warn us if the extension name is already
registered?

This appears to be a long-standing bug seen in XQuartz, and now in XWin as well.

Future work: Perhaps since RRXinerama isn't actually doing anything useful but
faking it when we have one screen, it seems that the PseudoramiX code could be
also used in that case.

Dave Airlie 8f4640bdb9 randr: cleanup provider properly
So in the cold plug server shutdown case, we reap the resources
before we call CloseScreen handlers, so the config->randr_provider
is a dangling pointer when the xf86CrtcCloseScreen handler is called,

however in the hot screen unplug case, we can't rely on automatically
reaped resources, so we need to clean up the provider in the xf86CrtcCloseScreen
case.

This patch provides a cleanup callback from the randr provider removal
into the DDX so it can cleanup properly, this then gets called by the automatic
code for cold plug, or if hot unplug it gets called explicitly.

Fixes a number of random server crashes on shutdown

Dave Airlie f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

Keith Packard 855003c333 randr: Catch two more potential unset rrScrPriv uses
Ricardo Salveti <ricardo.salveti@linaro.org> found one place where the
randr code could use the randr screen private data without checking
for null first. This happens when the X server is running with
multiple screens, some of which are randr enabled and some of which
are not. Applications making protocol requests to the non-randr
screens can cause segfaults where the server touches the unset private
structure.

I audited the code and found two more possible problem spots; the
trick to auditing for this issue was to look for functions not taking
a RandR data structure and where there was no null screen private
check above them in the call graph.

    xf86i2c: add pscrn for drivers to use

    This just adds a pScrn pointer into the struct for the drivers to use
    instead of scrnIndex. Mostly scrnIndex is used for logging, but some
    drivers use it to lookup xf86Screens, so let them stash a pScrn instead.

    Removing the scrnIndex is a bit more involved and I'm not sure its worth
    the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

    int10/vbe: don't use xf86Screens. (ABI) (v3)

    Pass the ScrnInfoPtr instead of the index in the int10 struct.

    This saves us using it to dereference xf86Screens.

    v2: address Alan's comment to fix struct alignment.

    v3: squash in all the int10 fixes, test the vm86 code builds,
    after comments by Keith.

Keith Packard 9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

Rui Matos 9cc44b955b randr: Make the RRConstrainCursorHarder logic the same as miPointerSetPosition
The constraining logic in RRConstrainCursorHarder allows the cursor to reach
crtc positions of x = width and y = height while the constraining code in
miPointerSetPosition only allows it to reach x = width - 1 and y = height - 1
for the analogous screen case.

This patch makes the former's logic equivalent to the latter's which allows
applications to benefit from Fitts's law. E.g. a maximized application
adjacent to a crtc border wouldn't get pointer events if the user moved the
pointer all the way until it's contained.

Aaron Plattner 08dfff92e8 randr: Compare all the bytes in RRPostPendingProperties
RRPostPendingProperties tries to compare the pending and current
property values to decide whether they're actually changing.  However,
it does this using a memcmp that passes in pending_value->size as the
number of bytes.  This is actually the number of elements, where each
element is (pending_value->format / 8) bytes long.  This causes the
pending value to not be propagated if the first pending_value->size
bytes are the same and only the end of it is changing.

Fix this by computing the total number of bytes to compare in the
memcmp.

Aaron Plattner b6c7b9b2f3 randr: check rotated virtual size limits correctly
Commit d1107918d4 introduced checks to
the RandR path that cause RRSetScreenConfig requests to fail if the
size is too large.  Unfortunately, when RandR 1.1 rotation is enabled
it compares the rotated screen dimensions to the unrotated limits,
which causes 90- and 270-degree rotation to fail unless your screen
happens to be square:

  X Error of failed request:  BadValue (integer parameter out of range for operation)
    Major opcode of failed request:  153 (RANDR)
    Minor opcode of failed request:  2 (RRSetScreenConfig)
    Value in failed request:  0x780
    Serial number of failed request:  14
    Current serial number in output stream:  14

Fix this by moving the check above the code that swaps the dimensions
based on the rotation.

Tobias Droste c7e4222c9a randr: set error numbers of resource types in RRExtenstionInit() (V2)
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367

Currently the ddx calls xf86RandR12Init()
  (-> RRScreenInit()
     -> RRInit()
       -> RRModeInit()
       -> RRCrtcInit()
       -> RROutputInit())
before RRExtensionInit() is called. This causes RRErrorBase
being 0 while setting resource type error values (resource types:
RROutput, RRMode and RRCrtc). The fix moves the setting of error
values to own functions which are called in RRExtensionInit()
to get the right RRErrorBase.

V2: With header file

Dave Airlie 80d1a548d6 rotation: fix cursor and overlap of one pixel.
Commit 77c7a64e88 was introduced to fix
a cursor off by one on Intel hw, however it also move the whole crtc
into an off by one position and you could see gnom-eshell overlapping.

This commit reverts that and instead fixes the cursor hotspot
translation to work like pixman does. We add 0.5 to the cursor vector
before translating, and floor the value afterwards.

Thanks to Soeren (ssp) for pointing out where the real problem was
after explaning how pixman translates points.

Jamey Sharp e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.
Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix uses this data, a screen private entry isn't appropriate.

xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

Jamey Sharp 4b9600a416 Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.
This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.

For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.

hw/xquartz/xpr/appledri.c has an interesting case: While its check for
"client == NULL" appears redundant with the test in WriteEventsToClient,
it dereferences client to get the sequence number.
