Hello,

I am hoping to find out if it is possible to increase the timing 
resolution on a TS-7250/7260 for a sampling application.  I am 
currently using gettimeofday(), which has a current minimum of 10 
milliseconds.

I came across a patch that allowed the kernel clock tick on a TS-7250 
to be increased from 100 Hz to 1024 Hz.  I do not recall the exact 
documentation but the general comment was that it was "at your own 
risk". 

Does anyone have any comments or experience relating to problems when 
the basic clock rate is increased?

Best regards
Roy
