POSIX clocks and ALSA

[Heikki Lindholm <holindho@cs.helsinki.fi>]

Hello,

Some years ago there was some talk about UST support in Linux, but the 
support never happened. With the hrtimers patch (and I'm not quite sure 
if even earlier?) CLOCK_MONOTONIC would seem like a fairly good UST time 
source. What I'd like to see, is a selectable clock for ALSA 
timestamping, e.g. something like snd_sw_params_clock(..., clockid_t 
clk). Would this seem plausible? I don't know that much about ALSA 
internals, so, no idea whether different clocks on different 
pcms/whatever would quickly turn into an unmanageable mess.
