To import DMAbufs we used VASurfaceAttribExternalBuffers which works, but it's not specific for DRM PRIME 2, since it lacks of many metadata. This patch replaces VASurfaceAttribExternalBuffers with VADRMPRIMESurfaceDescriptor in va_create_surfaces(). Still, this patch assumes linear modifier only. The hack for RGB surfaces in I965 driver was pushed down into va_create_surfaces() to avoid handling both structures.
