Richael Zhuang	d37462e56c	power: check frequencies count before filling array ... The freqs array size is RTE_MAX_LCORE_FREQS. Before filling the array with num_freqs elements, restrict the total num to RTE_MAX_LCORE_FREQS. This fix aims to fix the coverity scan issue like: Overrunning array "pi->freqs" of 256 bytes by passing it to a function which accesses it at byte offset 464.

Richael Zhuang	ef1cc88f18	power: support cppc_cpufreq driver ... Currently in DPDK only acpi_cpufreq and pstate_cpufreq drivers are supported, which are both not available on arm64 platforms. Add support for cppc_cpufreq driver which works on most arm64 platforms. Signed-off-by: Richael Zhuang <richael.zhuang@arm.com> Acked-by: David Hunt <david.hunt@intel.com>	2021-07-09 16:04:46 +02:00
