Function Documentation

geopm_agent_name()

int geopm_agent_name	(	int	agent_idx,
		size_t	agent_name_max,
		char *	agent_name
	)

The name of a specific agent.

Parameters

[in]	agent_idx	The index of the agent in question.
[in]	agent_name_max	Number of bytes allocated for the agent_name string.
[out]	agent_name	The name of the agent parameter provided by the indexed entry when the geopm_endpoint_num_agent() function is called. String is unmodified if an error condition occurs.

Returns

Zero if agent_name is large enough to hold the name, error code otherwise.

geopm_agent_num_avail()

int geopm_agent_num_avail

(

int *

num_agent

)

The number of available agents.

Parameters

[out]

num_agent

The number of agents currently available.

Returns

Zero if no error occurred. Otherwise the error code will be returned.

geopm_agent_num_policy()

int geopm_agent_num_policy	(	const char *	agent_name,
		int *	num_policy
	)

Get number of policy parameters supported by agent.

Parameters

[in]	agent_name	name of agent type.
[out]	num_policy	Number of policy parameters required by agent.

Returns

Zero if agent is supported, error code otherwise.

geopm_agent_num_sample()

int geopm_agent_num_sample	(	const char *	agent_name,
		int *	num_sample
	)

The number of sampled parameters provided by agent.

Parameters

[in]	agent_name	Name of agent type.
[out]	num_sample	The number of values provided by the agent when the geopm_agent_sample_name() function is called.

Returns

Zero on success, error code on failure.

geopm_agent_policy_json()

int geopm_agent_policy_json	(	const char *	agent_name,
		const double *	policy_array,
		size_t	json_string_max,
		char *	json_string
	)

Create a json file to control agent policy statically.

Parameters

[in]	agent_name	Name of agent type.
[in]	policy_array	Values for each of the policy parameters supported by the agent, array length is determined by the geopm_agent_num_policy() function.
[in]	json_string_max	Number of bytes allocated for json_string output.
[out]	json_string	Buffer that will be populated with JSON that can be used to create a policy file.

Returns

Zero on success, error code on failure.

geopm_agent_policy_json_partial()

int geopm_agent_policy_json_partial	(	const char *	agent_name,
		size_t	policy_array_size,
		const double *	policy_array,
		size_t	json_string_max,
		char *	json_string
	)

Create a json file to control agent policy statically.

Parameters

[in]	agent_name	Name of agent type.
[in]	policy_array_size	Number of policy parameters in the array. The number of policies passed must be less than or equal to the number returned by the geopm_agent_num_policy() function.
[in]	policy_array	Values for each of the policy parameters.
[in]	json_string_max	Number of bytes allocated for json_string output.
[out]	json_string	Buffer that will be populated with JSON that can be used to create a policy file.

Returns

Zero on success, error code on failure.

geopm_agent_policy_name()

int geopm_agent_policy_name	(	const char *	agent_name,
		int	policy_idx,
		size_t	policy_name_max,
		char *	policy_name
	)

Get the name of a policy parameter.

Parameters

[in]	agent_name	Name of agent type.
[in]	policy_idx	Index into policy vector.
[in]	policy_name_max	Number of bytes allocated for the policy_name string.
[out]	policy_name	The name of the policy controlled by the indexed entry. String is unmodified if an error condition occurs.

Returns

Zero if agent is supported, policy_idx in range, and policy name can be stored in output string, error code otherwise.

geopm_agent_sample_name()

int geopm_agent_sample_name	(	const char *	agent_name,
		int	sample_idx,
		size_t	sample_name_max,
		char *	sample_name
	)

The name of the indexed sample value.

Parameters

[in]	agent_name	Name of agent type.
[in]	sample_idx	Index into sampled parameters.
[in]	sample_name_max	Number of bytes allocated for the sample_name string.
[out]	sample_name	The name of the sample parameter provided by the indexed entry when the geopm_agent_sample_name() function is called. String is unmodified if an error condition occurs.

Returns

Zero if agent is supported, error code otherwise.

geopm_agent_supported()

int geopm_agent_supported

(

const char *

agent_name

)

Query if system supports an agent type.

Parameters

[in]

agent_name

Name of agent type.

Returns
