Hi Ilia,

thanks for your responses.

Also in my understanding, which is not professional but more of an hobbyist,
the drm planes model considered in drm_hwcomposer may have considered rotation
property as available in its first implementations/test cases.

IMHO since having no rotation is equivalent to having 0 rotation only,
I don't see the reason for drm_hwcomposer to throw the error in
drmplane.cpp:123, unless being born as an hwcomposer HAL and having a strong
requirement for it (or to "fake it").

Also I wanted to get your feedback, which is in line with KMS documentation,
that rotation property can be optional.

Thanks for your hint, drm_hwcomposer is now part of freedesktop.org

https://cgit.freedesktop.org/drm_hwcomposer

but I could not find how to submit a bug for drm_hwcomposer in bugzilla.
I think it should not be in 'DRI' section and it should not be in 'Mesa'

Mauro
