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. --- 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 .../sample_app_ug/l3_forward_power_man.rst | 8 + examples/l3fwd-power/main.c | 86 ++++++++++- lib/power/power_pstate_cpufreq.c | 24 ++- lib/power/rte_power_pmd_mgmt.c | 123 +++++++++++++++- lib/power/rte_power_pmd_mgmt.h | 139 ++++++++++++++++++ lib/power/version.map | 10 ++ 6 files changed, 379 insertions(+), 11 deletions(-)
