D18570: EGLStream DRM Backend Initial Implementation

romangg added a comment.


  First off: a driver not supporting Atomic Mode Setting is nothing modern. Does Nvidia has a plan to improve in this regard?
  
  I'm really not happy, that the `DrmOutput::present` is not run and we have to export these internals from DrmOutput to the EglStreamBackend, which replaces the flip with an EGL function call. Why does the Nvidia driver not integrate with the libdrm API in regards to page flipping? It should be possible to at least offer a wrapper around it or not?
  
  Why are there multiple texture copies necessary in EglStreamTexture and does this not have a performance impact?
