Subject: [PATCH v6 0/4] Add APIs for configurable power options
Date: Thu,  2 Jun 2022 16:13:35 +0100	[thread overview]
Message-ID: <20220602151339.86968-1-kevin.laatz@intel.com> (raw)
In-Reply-To: <20220408140847.1319312-1-kevin.laatz@intel.com>

The power library contains some variables which are currently set by
defines, hard-coded values or set using sysfs values. In order to
configure these, code changes and recompiles are required, making
configuring these variables tedious.

This patchset introduces some new get/set APIs which allow users and
applications to configure there settings to suit their use-cases.
In addition, CLI options have been added to l3fwd_power to demonstrate
how an application could use these APIs to expose the options to users
without needing code changes to configure them.

---
v6:
* fix units in doc API descriptions

v5:
* add doc updates for new APIs

v4:
* fix return value when scaling_freq_max is not set
* fix mismatching comments

v3:
* move setters from arg parse function to init
* consider 0 as 'not set' for scaling_freq_max
* other minor fixes

v2:
* add doc update for l3fwd-power
* order version.map additions alphabetically

Kevin Laatz (4):
  lib/power: add get and set API for emptypoll max
  lib/power: add get and set API for pause duration
  lib/power: add get and set API for scaling freq min and max with
    pstate mode
  examples/l3fwd_power: add cli for configurable options
