Hello Emil, my main system which I also used for development was stolen on Tuesday, so I won't be working on this series anytime soon. If anyone wants to pick it up, please go ahead. - Tobias Emil Velikov wrote: > On 22 November 2015 at 18:48, Tobias Jakobi > <tjakobi@math.uni-bielefeld.de> wrote: >> This allows setting the two direction registers, which specify how >> the engine blits pixels.

Hope you had some insurance and you manage to sort things out, relatively stress free. Inki, Hyungwon, other Exynos devs, Will you guys be able to pick any of this work ? Most of it can go in with the small suggestion in this patch addressed. Thanks Emil
Dear all, Yes. I can pick it on behalf of Tobias, if there is no one who can do that.
