Hi David, Thanks for your response.
We were worry about breaking the DPDK/FreeBSD on power, may hit the
similar bug:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241146
From my understanding, and also from the documentation
https://doc.dpdk.org/guides/freebsd_gsg/install_from_ports.html

dpdk only supports glibc at the moment.
Hi, Sorry for late response.
Yes this is the enhancement for powerpc. Observations on our power8/9
the __ppc_get_timebase calls __builtin_ppc_get_timebase () which is
result in calling the mftb instruction
__ppc_get_timebase():
mftb rA
this instruction on a 64-bit implementation cop

The commit title and log are quite short and give little idea on what
this is about.
I had a look at this glibc helper:
/* Read the Time Base Register. */
static __inline__ ui
__ppc_get_timebase() is GNU extension and is more efficient
v2: Advoid breaking other ppc_64 flatforms. The __ppc_get_timebase()
seems to be specific to powerpc platform and with GLIBC.
