[PATCH v4 0/9] drm/exynos: add async G2D execution to libdrm

[Tobias Jakobi]

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
