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.
v3: Rewrote handling of vendor-specific events. The series is now based on [1]. Also added two small fixes (error handling, break statement).
v4: Minor modification to the vendor-event handling code (drop opaque ptr). Series is based on this version [2] of the patch. Another two small fixes (buffer pixelformat, g2d_fini) added. The pixelformat issue surfaced after the recent changes to the Exynos mixer code. Also fixed a thread bug in the event test (application should always exit properly now).
With best wishes, Tobias
