the point here is, that the current header in libdrm in _not_ in sync
with the one in the kernel. It's hopelessly outdated, but mainly because
exynos/libdrm doesn't use any new functionality provided by some update.

Here's the current kernel header:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/include/uapi/drm/exynos_drm.h

The event stuff has been there since 2012:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/include/drm/exynos_drm.h?id=d7f1642c90ab5eb2d7c48af0581c993094f97e1a

The only reason why I haven't added the IPP things, is because I don't
intend to work on this for the moment.

Why shouldn't it? Isn't drmHandleEvent supposed to handle all kinds of
DRM events that the kernel produces?


With best wishes,
