Just gave the latest git driver a quick spin on OLPC XO-1.5 (VX855)
now that EXA has been enabled again.
However, composite doesn't seem to be working. viaExaCheckComposite_H6
is called a lot, and returns TRUE in most cases, but the
PrepareComposite and Composite functions are never called (tested by
inserting ErrorF statements, nothing gets printed).
Looking a little deeper, I see that exaTryDriverComposite calls
exaGetOffscreenPixmap() on the pixmap it is working with, which calls
down into exaPixmapHasGpuCopy_classic(), which returns:
ret = (pExaPixmap->use_gpu_copy && pExaPixmap->fb_ptr);
In this case, use_gpu_copy and fb_ptr always seem to be FALSE and NULL.
Is this working for anyone else, could someone else repeat the quick
