This patch series reworks the lcore ID verification logic within the power library to ensure consistency and improve maintainability. Currently, various cpufreq drivers implement their own lcore ID checks, often relying on simple range checks that do not account for whether a core is actually enabled in the application.
Key Changes: 1. Replaces basic range checks with rte_lcore_is_enabled() across all cpufreq drivers (ACPI, AMD P-state, CPPC, Intel P-state, and KVM VM). This ensures the power library only operates on lcores assigned to the application. 2. Introduces a common macro in the power library's internal headers to standardize lcore ID verification. 3. Moves the verification logic from individual driver implementations up to the high-level framework API. This reduces duplication code and ensures that all drivers benefit from uniform validation. 4. Updates the power QoS and PMD Management libraries to use the new macro.
