  There is probably at least a uinform handle.

  Which is good in theory but fails flat when we put graphics and the required performance into it, as Carmack argued about. https://marc.info/?a=111558719100068&r=1&w=4 https://marc.info/?a=111558719100068&r=1&w=4 http://rmitz.org/carmack.on.operating.systems.html http://rmitz.org/carmack.on.operating.systems.html

    I can't really find the failures you mention in the links you provided, can you point me to a more definitive source? Rob Pike replies here[1] that direct framebuffer access and networking are easy to get as new devices, although they need to be made available by the kernel. The "everything is a file" mantra doesn't fail, why would it? In the second link, Carmack just notices that plan9 is pretty dead, and we all know it is :) [1] https://marc.info/?l=9fans&m=111558695515846&w=4 https://marc.info/?l=9fans&m=111558695515846&w=4

      It fails because it doesn't match the performance that other approaches are able to achieve. Everything is a file is how X Windows over network kind of works. For real graphics performance that can match other systems, xshm and DRM had to be developed.
