Public bug reported:
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 :)
