Eric Anholt 261c20a479 uxa: Add in EnableDisableFBAccess handling like examodule.c did. 
This fixes assertion failures when rendering text while VT switched.

Dave Airlie 293f6232c6 uxa: don't call composite routines with no buffer. 
We can get a case with gnome-terminal + links, where we get two arrays
of glyphs all with 0 width and 0 heights in them. If this happens
we manage to get to this case without any buffer setup and segfault.

(cherry picked from commit 717c7492a0f6ba3fb3eabda33515881eef314155)

Jesse Barnes f082e877d5 Work around gcc uninitialized variable warnings 
GCC isn't smart enough to analyze the control flow and figure out that
these are false positives, but initializing them shouldn't hurt, so work
around it.

Eamon Walsh 808b72f814 Change uxa private keys to integer variables. 
Prepares for a devPrivates system that will store an index.

Keith Packard fc3e287e6b [uxa] Remove unused pixmap size limits. 
All size-related rendering limits should be managed by the driver in the
pixmap_is_offscreen call. There's no need for uxa to even know these values.

Keith Packard 68f0872db6 [uxa] Check xalloc returns and deal with failure 
Failing xalloc in a rendering function means just dropping the drawing on
the floor (that's what we've always done).

Keith Packard fc4d9c55a7 Change PrepareAccess to take access mode rather than index 2008-08-05 15:41:51 -07:00
Keith Packard 4cc20b7f6e Don't call sync on prepare_access -- just let the driver deal with it. 
Let the driver do whatever sync is necessary from the prepare_access hook
rather than forcing a full sync.

Keith Packard 59774e9aca Add UXA - the unified memory acceleration architecture. 
This eliminates the cost of EXA migration management while providing full
pixmap allocation control to the driver. The goal is to make something
useful for UMA drivers.
