	graesslinUnsubmitted Done general coding style comment. Types normally start with a capital letter. So Property (no need for the Enum suffix, It's properly namespaced). Also for enums we prefer to use the new enum class nowadays which gives you proper namespacing. And the enum values follow the normal CamelCase rules. So for this enum it should be something like: enum class Property { Crtc, Count }; graesslin: general coding style comment. Types normally start with a capital letter. So Property (no need…
	romanggAuthorUnsubmitted Done I tried using enum classes but the problem is, that you can't subclass them and implicit conversion between int and enum class are not allowed. Look at DrmObject::propValue(int index) and the other property functions there. You want to call them with the enum implemented in the respective subclass, but if you do it with enum classes, you would need always a static cast (look at DrmOutput::atomicReqModesetPopulate, why this would be ugly. romangg: I tried using enum classes but the problem is, that you can't subclass them and implicit…
	graesslinUnsubmitted Done you don't need to static_cast. You can also int(EnumValue). graesslin: you don't need to static_cast. You can also int(EnumValue).
