v3 changes: - implement in .c files instead of exporting an inline arch function - rename arch function from rte_rdtsc_arch_hz to get_tsc_freq_arch - integrate x86 implementation in the series - fix private EAL include in PPC implementation (not tested)
From: Gowrishankar Muthukrishnan <gowrishanka...@linux.vnet.ibm.com> Some architecture like armv8 provides an architecture specific function to get the rdtsc frequency. The existing rdtsc calibration scheme uses OS serivce like sleep(1) to calibrate the frequency which may not produce the accurate result. Introducing an architecture specific hook to get the rdtsc frequency if architecture provides it. If not, use the exiting the calibrate scheme to get the rdtsc frequency.
