[Mesa-dev] [PATCH v2 0/5] XA composite and perf improvements and fixes

[Thomas Hellstrom]

Hi, Rob,

Do you think we can push patches 1 trough 3 with a CC to stable for
patch 3?
(It for some reason fixes a rendering error with motif on vmwgfx).

I'm still looking into patches 4 and 5 to investigate why I get
rendering errors.

/Thomas
