Hi Alexandros, I'm using the latest DDK 1.7 with a PandaBoard 2.0 and getting the following time when executing:

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 :) _______________________________________________ Mailing list: https://launchpad.net/~tiomap-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~tiomap-dev More help : https://help.launchpad.net/ListHelp
