Consider below sequence -
1) Cursor is removed : isUp will be FALSE if HW cursor is set.
2) VT switched away from X : vtSema becomes FALSE.
3) xf86CursorSetCursor is called with non-null CursorPtr :
Saves the passed in CursorPtr, fallbacks to SW cursor and invokes
spriteFuncs->SetCursor which saves the area under cursor and restores
the cursor. This sets isUp to TRUE and as vtSema is FALSE saved data
is garbage.
4) VT switched to X : vtSema becomes TRUE. xf86Cursor enable fb access
is called which will remove the SW cursor, i.e copies saved data in #3
to screen.
This results to momentary garbage data on screen. Hence when !vtSema
skip spriteFuncs->SetCursor.

This is derived from the intel driver DRI2 code, with swapchain and
pageflipping dropped, functions renamed, and vblank event management
shared code moved to a vblank.c for reuse by Present.
This allows AIGLX to load, which means that you get appropriate
visuals exposed in GL, along with many extensions under
direct-rendering that require presence in GLX (which aren't supported
in glxdriswrast.c).
v2: Drop unused header includes in pageflip.c, wrap in #ifdef GLAMOR.
Drop triple-buffering, which was totally broken in practice (I'll
try to fix this later). Fix up some style nits. Document the
general flow of pageflipping and why, rename the DRI2 frame event
type enums to reflect what they're for, and handle them in a
single switch statement so you can understand the state machine
more easily.
v3: Drop pageflipping entirely -- it's unstable on my Intel laptop
(not that the normal 2D driver is stable with pageflipping for
me), and I won't get it fixed before the merge window. It now
passes all of the OML_sync_control tests from Jamey and Theo
(except for occasional warns in timing -fullscreen -divisor 2).
v4: Fix doxygen at the top of vblank.c

This will be used by the modesetting driver to support DRI2 across all
hardware that can support glamor, and could potentially be used by
other drivers that have to support DRI2 on sets of hardware with
multiple Mesa drivers.
This logic is the same as what's present in the Mesa driver loader,
except for the lack of nouveau_vieux support (which requires a
predicate on the device).
v2: Fix duplicated assignment of info->driverName.

This comes from Mesa commit acdcef6788beaa2a1532e13ff84c3e246b8025ed
Previously, each driver had to tell DRI2 what GL driver object should
be loaded. Originally for a 2D driver that was a matter of giving the
constant string for the vendor name, same as the driver's name. For a
driver that's trying to handle multiple generations of hardware with
different Mesa driver filenames, the driver had to bake in a mapping
from PCI ID to the appropriate driver name in Mesa, which seems like a
pretty awful layering violation (and one that was fixed with DRI3)
As of January, Mesa now handles the mapping from a DRI fd to the
driver name on its own, but the AIGLX loader still relies on DRI2 for
choosing the filename. Instead of propagating the PCI ID list from
each 2D driver to the modesetting driver, import a central copy of the
PCI ID list so that drivers can stop handling this themselves. (Some
day, when AIGLX transitions to EGL, we can drop the DRI2 filename
setup entirely).

A careful read shows that it was always NULL. It hasn't always been; as
the DDX spec indicates, it was the "occluded region that has backing

As the man page says, "unsupported, experimental, and barely
functional". The last even minor updates to any of this were back in
2004, presumably it's not getting better any time soon.
This is also the only GC ops implementation in the tree that actually
falls all the way down to the spans routines for everything, so that's
pretty nice to be rid of.
