This has been true for a while, but it did used to work, so hopefully it will not be too hard to fix. http://lists.freedesktop.org/archives/openchrome-devel/2012-July/000731.html http://lists.freedesktop.org/archives/openchrome-devel/2012-July/000732.html >> 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). > > Yipes!!

Good question - I was also thinking about this subject, which is why I tried the latest version. 1. EXA working 2. Basic Xv working 3. Screen rotation See http://lists.freedesktop.org/archives/openchrome-devel/2012-August/000736.html for the options I was going to try the GECMD rotate bits (http://lists.laptop.org/pipermail/devel/2010-October/030226.html) now, until I found that EXA wasn't being called. Another option is using the 3d engine for rotation, as xf86-video-chrome does. At a glance, I think it might be quite easy: maybe it is just a case of transforming the coordinates sent to emitQuad. See how viaAccelTexture3DBlt() (in via_3d.c in xf86-video-chrome source) calls viaTransformCompute() before calling emitQuad. That might be a good quick test to run. However, I am not 100% sure that I am looking at the right codepath. 4. Multiple Xv sufaces This is implemented by xf86-video-chrome, I haven't looked into the details yet. xf86-video-chrome source is http://dev.laptop.org/git/users/jnettlet/xf86-video-chrome/ Thanks Daniel _______________________________________________ Openchrome-devel mailing list Openchrome-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/openchrome-devel
