The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.
v3: Add/remove the XID map from the vendor private thunk, not the
backend. (Kyle Brenneman)
v4: Fix deletion of ghost contexts (Kyle Brenneman)

The only way to get at xf86Info.disableRandR from configuration is

The install rule of Xorg.wrap is currently a dependency of the
install-data target instead of the install-exec target. The build also
uses install-exec-hook to change the ownership and set the SUID bit on
the Xorg.wrap binary. The problem is that install-exec-hook is only
ordered respective to the install-exec target, the rules of install-data
may or may not have been executed.
If install-exec-hook runs before the Xorg.wrap binary is in place,
a message similar to the following will be present in the build log:
chown: cannot access '/pkgdir/usr/lib/xorg-server/Xorg.wrap': No such file or directory
make[6]: [Makefile:1151: install-exec-hook] Error 1 (ignored)
All that needs to be done is to change the name of the program variable
to contain 'exec' for the install rule to depend on the install-exec
target.
Excerpt from the Automake manual, chapter 12.2 The Two Parts of Install:
"Any variable using a user-defined directory prefix with ‘exec’ in the
name (e.g., myexecbin_PROGRAMS) is installed by install-exec. All other
user-defined prefixes are installed by install-data."

#if XORG_VERSION_CURRENT >= XORG_VERSION_NUMERIC(6,8,99,13,0)
#define SISCHECKOSSSE /* Automatic check OS for SSE; requires SigIll facility */
#endif
Which means it has never worked in any modular server release.
A less gross way to do this is to check for SSE support with getauxval()
or /proc/cpuinfo or similar. Since no driver is using the existing

Change 677c32bc refactored all usages of drmWaitVBlank() into a helper function,
ms_queue_vblank().
ms_queue_vblank() takes in an MS_QUEUE_RELATIVE flag to indicate that the
sequence number is relative rather than absolute, but still treats the actual
sequence number as absolute, passing it through ms_crtc_msc_to_kernel_msc()
unconditionally before calling drmWaitVBlank().
ms_crtc_msc_to_kernel_msc() works by subtracting a vblank offset from the
provided sequence number, which only makes sense for absolute sequence numbers.
In the case of PRIME Sync, drmmode_SharedPixmapPrsentOnVBlank() passes in 1,
which results in a large negative vblank offset. After subtracting, we're left
with a relative sequence number of 100,000+, i.e. wait for 100,000+ vblanks...
In the relative case we want to pass in the sequence number unmodified. Simply
add a check to do this.

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

In contrast to UDL, EVDI uses platform devices, thus instead of 'usb' in

Despite all the careful planning of the kernel, a link may become
insufficient to handle the currently-set mode. At this point, the
kernel should mark this particular configuration as being broken
and potentially prune the mode before setting the offending connector's
link-status to BAD and send the userspace a hotplug event. This may
happen right after a modeset or later on.
Upon receiving a hot-plug event, we iterate through the connectors to
re-apply the currently-set mode on all the connectors that have a
link-status property set to BAD. The kernel may be able to get the
link to work by dropping to using a lower link bpp (with the same
display bpp). However, the modeset may fail if the kernel has pruned
the mode, so to make users aware of this problem a warning is outputed
in the logs to warn about having a potentially-black display.
This patch does not modify the current behaviour of always propagating
the events to the randr clients. This allows desktop environments to
re-probe the connectors and select a new resolution based on the new
(currated) mode list if a mode disapeared. This behaviour is expected in
order to pass the Display Port compliance tests.

to using a software cursor and never go back. Change this to only
permanently switch to a software cursor if -ENXIO is returned (which means
hardware cursors not supported), and to otherwise still try a hardware
cursor first every time a new one is set. This is needed because hardware

others.

There is currently no reliable way to report failure to set a HW

ioctl fails (which currently happens at least with modesetting on Tegra

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.
