if you do a vDSO implementation, please do not limit the

I do see your point.
Right now I extracted (most of) the hardware depending stuff (i.e. the
performance timer access including calibration) out of EpikTimer.pas in
a new not class-driven unit EpikTimerBase that is used by EpikTimer and
in the end should be usable without EpikTimer.pas.
Right now it just accesses the X86 performance register directly.
This unit could use a vDSO Unit that contains access via
__vdso_clock_gettime().
Here other such functions could be places (e.g. for x86 and x86/64::
__vdso_getcpu(), __vdso_gettimeofday() and __vdso_time() ).
