We discussed a lot about how to prevent the user shooting him/herself in
the knee with inter-tick timestamps, but I still think that
rtdm_clock_read_tsc() would even be worse in this regard.
What do you think abou this documentation:
"This function is meant to be used in periodic mode for getting a high
timestamp, independently from the system timer's tick.
Its return values should not be used mixed with rtdm_clock_read() values
because they are not syncronised.
Driver authors[developers?] are advised to state this on driver
documentation for the final users where returning these values to them
for avoiding confusion.
Note: This function is available for uniprocessor systems only in the
meantime."
I think it explains and will not make confusion in driver developers...
If sometime someone give a good solution to the syncronisation problem
between multiple processors, this can be changed...
