Audio threads scheduling

Hi,

I've made some test to undersand the audio thread scheduling parameters. Here are the value I get using the "thread_policy_get" function to retrieve the scheduling parameters for various buffer size :


Frames : period : computation : constraint : preemptible

32 725 499 725 1
48 1080 499 1080 1
64 1451 499 1451 1
128 2902 299 2902 1
256 5804 99 5804 1
512 11608 99 11608 1

As expected the period and constraint values are directly related to the buffer size, but I don't understand how the value of the computation parameter are choosen.

Any comments?

Regards

Stephane Letz
