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
