[PATCH v1 00/15] power: unify and improve lcore ID verification

[PATCH v1 00/15] power: unify and improve lcore ID verification

[Huisong Li]

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.

The rte_lcore_is_enabled() will return false for service lcores.
Is this a bug or a feature here?

Sorry for this.
Yeah, I used checkpatch.sh and check-git-log.sh before sent out.
But it didn't found this. I guess that because the "locre" is not a word.

My understanding is that the ROLE_RTE core is used to tasks on data 
plane and the ROLE_SERVICE core is used to periodic or control-plane tasks.
Currently, power management in DPDK is mainly processed based on 
services on the data plane, like the usage in pmd_mgmt or l3fwd-power.
However, the tasks on the service cores may also occupy 100% CPU.
Therefore, power library or driver should be able to be work with these 
tasks.
 From this perspective, allowing the ROLE_SERVICE core to set power has 
the least impact on applications in this series.
what do you think, Stephen?

Hi Sivaprasad,

Do you think we need to allow the role_service core to set cpufreq?

Service lcore's are just things doing other work.
They really should not be doing non-blocking poll, that is a mistake.
The service cores are intended for control path things.

The power API should ignore them in general but not break if a user
calls a power API from a service thread.

What you suggest is that we should allow the service core to 
successfully set the power API?
I know this approach has the least impact.

However, pmd_mgmt lib is also used together with the data plane task of 
network devices.
They should only allow the ROLE_RTE core to use them.
I originally wanted to extract a common macro to verify the lcore in 
power lib.
This common macro is not appropriate to pmd_mgmt lib if this common 
macro counts ROLE_SERVICE core as valid.

But we don't know if aplication having the service core thread used 
cpufreq API.
Although they may not be used in general, it seems that we need allow 
the service core to set the cpufreq API.

[PATCH V2 00/15] power: unify and improve lcore ID verification

[Huisong Li]

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,
which are limited to simple range validation and involve significant
code duplication. Moreover, these checks do not account for whether the
core is actually managed by the application.

For the verification in cpufreq-related APIs and power QoS APIs, although
service cores do not typically invoke these APIs, they may operate in
polling modes where power management is required. To maintain compatibility
with applications using service cores, the validation logic now explicitly
allows both ROLE_RTE and ROLE_SERVICE.

But the lcore ID in the pmd_mgmt library must be ROLE_RTE because it is
mainly used together with the data plane of ethdev PMD. So use
rte_lcore_is_enabled to verify.

Key Changes:
1. Add lcore role verification to individual cpufreq drivers.
2. Introduces a unified macro in the power library to standardize lcore ID
   checks.
3. Moves verification logic from individualdrivers to the framework level.
   This reduces code duplication.
4. Allow the service cores to configure power QoS.
5. Use rte_lcore_is_enabled to verfify the lcore ID in pmd_mgmt.

---
v2:
 - Allow the service cores to set power API.

[PATCH V2 01/15] eal: add interface to check if lcore is EAL managed

[Huisong Li]

Add a new helper function rte_lcore_is_eal_managed() to determine
if a logical core is managed by EAL.

This interface returns true if the lcore role is either ROLE_RTE
(standard worker/main cores) or ROLE_SERVICE (service cores).

[PATCH V2 02/15] power/kvm_vm: validate lcore role in cpufreq API

[Huisong Li]

Currently, the kvm_vm driver only checks if the lcore_id is within
the RTE_MAX_LCORE range, but fails to verify if the core is actually
active or managed by the application. This lacks sufficient validation.

This patch add a lcore role check to the cpufreq-related APIs.
Although service cores do not typically invoke these APIs, they may
operate in polling states where power management is required.
To maintain compatibility with applications using service cores, the
validation logic now explicitly allows both ROLE_RTE and ROLE_SERVICE.

[PATCH V2 06/15] power/intel_pstate: validate lcore role in cpufreq API

[Huisong Li]

Currently, the intel_pstate driver only checks if the lcore_id is
within the RTE_MAX_LCORE range, but fails to verify if the core is
actually active or managed by the application. This lacks sufficient
validation.

This patch add a lcore role check to the cpufreq-related APIs.
Although service cores do not typically invoke these APIs, they may
operate in polling states where power management is required.
To maintain compatibility with applications using service cores, the
validation logic now explicitly allows both ROLE_RTE and ROLE_SERVICE.

[PATCH V2 15/15] power: add lcore ID check for PMD mgmt

[Huisong Li]

The pmd_mgmt lib is mainly used together with the data plane of ethdev
PMD. The core in data plane is ROLE_RTE. So use rte_lcore_is_enabled
to verify it.

Fixes: 6f987b594fa6 ("power: refactor core power management")
