Hello,
this series exposes async execution of G2D command buffers to userspace. Also includes is a small performance analysis test, which can also be used to stress test the engine. The async operation is of course also tested.
Please review and let me know what I can improve.
With best wishes, Tobias
Almost forgot this. In case someone is interested in the solid fill performance, I've uploaded a plot here: http://www.math.uni-bielefeld.de/~tjakobi/exynos/g2d_clear_perf.pdf
And yes, that should be _nano_seconds on the y-axis. What I find interesting that despite the performance being linear (well, affine linear, since we have a setup time) in the number of pixels to process, you can still see some kind of 'clustering'. I wonder where this comes from, maybe some small alignment penalty, or something?
With best wishes, Tobias
