Since it's storing an locally defined (ddx-internal) data, it's better
not to abuse some globally defined key for this.
It just happened to work before, since CursorScreenKey is only used by DDX
(and there's only one DDX per executable) and they currently (!) have the
same size (pointer) - but that's a fragile programming style, so clean it up.

Similar to change cba5a10f, xf86ScreenSetCursor() would dereference ScreenPriv
without NULL checking it. If Option "SWCursor" is specified, ScreenPriv == NULL.
Without this fix, it is observed that setting Option "SWCursor" "on" on the
modesetting driver in a PRIME configuration will segfault the server.
It is important to return success rather than failure in the instance that
ScreenPriv == NULL and pCurs == NullCursor, because otherwise xf86SetCursor()
can fall into infinite recursion: xf86SetCursor(pCurs) calls
xf86ScreenSetCursor(pCurs), and if FALSE, calls xf86SetCursor(NullCursor). If
xf86ScreenSetCursor(NullCursor) returns FALSE, it calls
xf86SetCursor(NullCursor) again and this repeats forever.

Based on v4 by Alexandre Courbot <acourbot@nvidia.com>
There is currently no reliable way to report failure to set a HW
cursor. Still such failures can happen if e.g. the MODE_CURSOR DRM
ioctl fails (which currently happens at least with modesetting on Tegra
for format incompatibility reasons).
As failures are currently handled by setting the HW cursor size to
(0,0), the fallback to SW cursor will not happen until the next time the
cursor changes and xf86CursorSetCursor() is called again. In the
meantime, the cursor will be invisible to the user.
This patch addresses that by adding _xf86CrtcFuncs::set_cursor_check and
_xf86CursorInfoRec::ShowCursorCheck hook variants that return booleans.
This allows to propagate errors up to xf86CursorSetCursor(), which can
then fall back to using the SW cursor immediately.
v5: Updated the patch to apply to current git HEAD, split up into two
patches (server and modesetting driver) and adjusted the code slightly
to match surrounding code. I also removed the new exported function
ShowCursorCheck(), as instead just changing ShowCursor() to return Bool
should not affect its current callers.

xf86RecolorCursor() may be called directly from XRecolorCursor as well
as from xf86ScreenSetCursor(). In the latter case, the input lock is
already held, but not for the former and so we need to add a wrapper
function that acquires the input lock before performing
xf86RecolorCursor()

xf86CheckHWCursor() would dereference sPriv without NULL checking it. If Option
"SWCursor" is specified, sPriv == NULL. In this case we should assume that HW
cursors are not supported.

Prevents the HW cursor from intermittently jumping around when the
cursor image is changed while the cursor is being moved. This is hardly
noticeable in normal operation but can be quite confusing when stepping
through these codepaths in a debugger.

xf86CursorScreenRec::HotX/Y contain 0 for PRIME slave screens.
Fixes incorrect HW cursor position on PRIME slave screens.
Also hoist the hotspot translation out from xf86ScreenSet/MoveCursor to
xf86Set/MoveCursor, since the hotspot position is a property of the
cursor, not the screen.
v2:
* Squash patches 1 & 2 of the v1 series, since it's basically the same
problem
* Use the master screen's xf86CursorScreenRec::HotX/Y instead of
CursorRec::bits->x/yhot, since CursorRec::bits can be NULL (Hans de
Goede)

Currently with PRIME if we detect a secondary GPU,
we switch to using SW cursors, this isn't optimal,
esp for the intel/nvidia combinations, we have
no choice for the USB offload devices.
This patch checks on each slave screen if hw
cursors are enabled, and also calls set cursor
and move cursor on all screens.

load_cursor_argb() may need to be able to fail and have the server fall back
to a software cursor in at least the following circumstances.
1) The hardware can only support some ARGB cursors and this does not just
depend on cursor size.
2) Virtual hardware may not wish to pass through a cursor to the host at a
particular time but may wish to accept the same cursor at another time.
This patch adds a return value to the API and makes the server do the
software fall-back on failure.

Commit 0c6987df in June 2008 disabled XAA offscreen pixmaps per default,
as they were broken, leaving XAA only able to accelerate operations
directly on the screen pixmap and nowhere else, eliminating acceleration
for basically every modern toolkit, and any composited environment.
So, it hasn't worked for over four years. No-one's even come close to

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)
