I actually have no idea at the moment on how the enum > namespace is handled in C. But anyway, none of this matters hugely. No, I mean whatever we write today, we have to convert to the canonical form when we have i915_drm.h. Just enum's make me more uneasy than defines (esp. with a C++ compiler). I actually quite like that if we locally #define I915_ENGINE_CLASS_RENDER A then we get an error if we import a kernel header #defining to B, but LOCAL stands out and is easy to grep. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
