As i already said dri is intented to be an api btw 2 part of the same driver, at no time it was designed to allocate buffer for general use and there is no way to allocate buffer in hw independant maner. If you really would like to be able to do direct pixel banging on buffer that can the be use by the GPU (i guess use case here is for wayland) i think you would need to build a library that can provide an API and have backend for each GPU we care about (amd,intel,nvidia). Such library could be an add on to the drm one and likely leave in the same repository.

Because there is an ever increasing number of embedded micros with GPUs, there is less need to emulate a GPU-less system. Therefore, i'll increase my minimum requirements. ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev

From the underlying X drawable. Beware that this is old DRI1 stuff, which shouldn't be used for new development. -- Earthling Michel Dänzer |http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
