query and profiling data

Functions
static int	HAP_compute_res_query_capability (compute_res_capability_id capability_id, unsigned int *data)
static int	HAP_compute_res_get_preempt_data (unsigned int context_id, compute_res_preempt_data_t *data)

Detailed Description

API to query capabilities of the compute resource manager and to get profiling data associated with a context.

Function Documentation

HAP_compute_res_get_preempt_data()

static int HAP_compute_res_get_preempt_data ( unsigned int  context_id, compute_res_preempt_data_t *  data  )

inlinestatic

On implementations supporting HAP_COMPUTE_RES_AUTONOMOUS_PREEMPTION, this API returns preemption statistics associated with the context_id acquired via HAP_compute_res_acquire().

This API needs to be called before the associated context is released via HAP_compute_res_release() call, data returned is invalid otherwise.

Parameters

[in]	context_id	Context ID returned by HAP_compute_res_acquire().
[out]	Pointer	to compute_res_preempt_data_t. On success, the preemption-related statistics are updated in the provided structure.

Returns

0 upon success.
Nonzero upon failure.
HAP_COMPUTE_RES_NOT_SUPPORTED when not supported.

HAP_compute_res_query_capability()

static int HAP_compute_res_query_capability ( compute_res_capability_id  capability_id, unsigned int *  data  )

inlinestatic

Queries compute resource manager capabilities listed under compute_res_capability_id enum.

Parameters

[in]	capability_id	Identifier from compute_res_capability_id corresponding to the compute resource manager capability.
[out]	data	Pointer to an unsigned int data. On success, the memory is updated with the data associated with the queried capability.

Returns

0 upon success.
Nonzero upon failure.
HAP_COMPUTE_RES_NOT_SUPPORTED when not supported.
