Subject: [PATCH v1 00/15] power: unify and improve lcore ID verification
Date: Thu, 16 Apr 2026 11:05:57 +0800 [thread overview]
Message-ID: <20260416030612.2379407-1-lihuisong@huawei.com> (raw)
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.
Huisong Li (15):
power/kvm_vm: enforce enabled lcore ID check
power/acpi_cpufreq: enforce enabled lcore ID check
power/amd_pstate: enforce enabled lcore ID check
power/cppc_cpufreq: enforce enabled lcore ID check

power: enforce enabled lcore ID check
power: add a common macro to verify lcore ID
power/pmd_mgmt: replace lcore ID verification with new macro
