Title:
  Calling eglInitialize() takes too long

Status in Ubuntu OMAP4 graphics addons:
  Fix Released

Bug description:
  With the latest drivers on an SDP 4430 board calling eglInitialize
  takes extremely long. Running the example program (attached) on an
  completely idle system produces the following results:

  # time ./eglinit       
  real	0m5.797s
  user	0m0.008s
  sys	0m1.055s

  # time ./eglinit
  real	0m10.523s
  user	0m0.008s
  sys	0m1.047s

  # time ./eglinit
  real	0m30.459s
  user	0m0.008s
  sys	0m1.055s

  # time ./eglinit
  real	0m5.638s
  user	0m0.008s
  sys	0m1.055s

  # time ./eglinit
  real	0m10.088s
  user	0m0.008s
  sys	0m1.047s

  I have attached an strace capture of a sample run that shows that the
  delay is happening in an ioctl() around line 10000.

  The trace also shows that the driver wastes a lot of time trying out
  /dev/dri/* devices, but that is another subject :)
