May I ask to avoid HWC2 only implementation? The main reason is not all GPUs support drm_hwcompser (as discussed in another thread). To continue supporting these GPUs we need to keep using HWC1 version of SurfaceFlinger. So it's better to keep the code compatible with HWC1. At least make it be a compile-time option. Personally I have a patch to make HWC1 vs HWC2 a compile-time choice of drm_hwcomposer. I can submit it if it's acceptable. -- Chih-Wei Android-x86 project http://www.android-x86.org _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
