This is neither broken nor embedded. All the items mentioned are
mainline POWER server architecture. Some of these have been around a
long time (for example the timebase is V1.0 architecture from 1993).
The problem we face is legions of programmers who don't know and refuse
to learn assemble but want access to these features. We are trying to
provide a reasonable and simple to use solution to the many requests we
git from our customers.
Now if you think only PowerPC has these issue, consider all the random
attempts to use the rdtsc instruction you might have seen, and how
useful it would be to have one well defined and correct version every
one could use.
