   2  * SGI Rendering Resource Manager API (?).

   4  * written by Miguel de Icaza (miguel@nuclecu.unam.mx)
   5  *
   6  * Ok, even if SGI choosed to do mmap trough ioctls, their
   7  * kernel support for virtualizing the graphics card is nice.
   8  *
   9  * We should be able to make graphic applications on Linux
  10  * fly.
  11  *
  12  * This header file should be included from GNU libc as well.
