Took to long to edit my last post... anyway, with the way things are going perhaps Glamor will be the way to go on GMA500.

Intel Glamor Acceleration Compared To SNA, UXA

Originally posted by hwertz View PostI'd love if the SNA work was applicable to the GMA500. I have video acceleration (VA-API) and all that working and it's pretty nice, certain 2D operations are quite a bit slower than it seems like they should be so if SNA has different caching and memory management strategies I expect it could radically affect performance on it too. I don't know where the "binary blob"/"open source" line is on this driver though, if the blob insists on managing memory itself than nothing can be done with it.
Back to the original discussion, SNA actually has broadly similar ideas of pixmap migration to EXA upon which the proprietary Poulsbo driver is based; so in reality the only limiting factor for that driver is its quality of implementation. That it is not open source speaks volumes for the level of confidence and commitment Intel have made for that GPU and driver.
