From: Hongbo Zhang <hongbo.zh...@linaro.org> v3 -> v4 changes: - rebase to latest odp version - add odp_cpumask_available() to iterate each cpu v2 -> v3 changes: - move all CPU related API declaration into cpu.h - refine tests for per-CPU APIs - revise API for getting current frequency v1 -> v2 changes: - separate original 1/3 patch to two - add validation patch to test new APIs - other minor updates upon review comments v1 notes: The current API of getting CPU frequency is really ambiguous. CPU has its max frequency, and if enabled, the current frequency may be scaled from time to time, what's more, on some AMP platforms, cores are heterogenous, they have different max and current frequencies. This patch set cleans up these above issues. Patch 1/3 makes cpu_hz and model_str to be per-CPU data, then on AMP system, it is possible to acquire data for each different CPU. Patch 2/3 makes it clear that the cpu_hz stands for max CPU frequency Patch 3/3 adds new API to get the current CPU frequency if needed. Due to lack of test platform, only x86 platform is implemented right now, the others should follow up if this patch set is accepted.
