Yes. > Also make sure your baseline have this patch: > > - "omap:iommu-load cam register before flushing the entry" Huh? That's not even in v2.6.36-rc7, in which baseline is this supposed to be in? Anyway, I'll try adding that. > What kind of error are you getting? Node allocation failing IIRC. > I don't have a complete framework to test MM testcases at this moment See: http://felipec.wordpress.com/2010/10/08/my-arm-development-notes/ I even prepared a tarball so you just need to extract it on your device. It's not difficult to test this with GStreamer, and I don't see how you can be confident that they indeed work without testing some real use-cases. Anyway, I'll try that missing patch.
