Heya!
How is the 'dir' argument in snd_pcm_hw_params_set_periods_near() supposed to work?
I'd assume that passing dir=1 would mean that it is looked for a number of periods that is greater *or equal* to what we request. If we pass dir=-1 we'd be looking for a number of periods that is smaller *or equal* to what we request.
However, what I am experiencing is that there is no "or equal". On my softvol on hda setup here if I ask for 5 periods I will always get 6 if I pass dir=1 -- even if the could give me 5 and will give me five if I pass dir=0.
The docs don't really elaborate on this much.
I'd certainly think that having ">=" and "<=" here is much more useful and natural than ">" and "<", and hence I was wondering: is this just a bug in the software or is it really intended to be this way?
