Android-x86 is the first open source project that brought Mesa/DRM to the Android platform. Refer to: http://sourceforge.net/p/android-x86/external_libdrm/ http://sourceforge.net/p/android-x86/external_mesa/ http://sourceforge.net/p/android-x86/external_drm_gralloc/ (Drm based gralloc HAL) It's glad to see drm_gralloc is now a part of AOSP marshmallow release. Google Pixel C is probably the first (and only?) one android product that uses it. We have a devel group working on that. If you are interesting, I can invite you to join. -- Chih-Wei Android-x86 project http://www.android-x86.org

DRM support in Android
Hii all, I want to know some information regarding DRI and DRM support in android.Does Android uses DRI drivers in MESA for Direct rendering.Can DRI drivers alone can be used without DRM ? I am pretty confused that how Direct rendering is performed in android whether by DRI or some other method.Struggling with this problem since many days but did n't find any answer .Please do help me. Thanks and Regards. -- next part -- An HTML attachment was scrubbed... URL: <http://lists.freedesktop.org/archives/dri-devel/attachments/20160105/ec176b37/attachment.html>
