Detailed Description

struct drm_ivpu_metric_streamer_start - Start collecting metric data

Member Data Documentation

max_data_size

__u32 drm_ivpu_metric_streamer_start::max_data_size

@max_data_size: Returned max @data_size from DRM_IOCTL_IVPU_METRIC_STREAMER_GET_DATA

metric_group_mask

__u64 drm_ivpu_metric_streamer_start::metric_group_mask

@metric_group_mask: Indicates metric streamer instance

read_period_samples

__u32 drm_ivpu_metric_streamer_start::read_period_samples

@read_period_samples:

Number of samples after which user space will try to read the data. Reading the data after significantly longer period may cause data loss.

sample_size

__u32 drm_ivpu_metric_streamer_start::sample_size

@sample_size: Returned size of a single sample in bytes

sampling_period_ns

__u64 drm_ivpu_metric_streamer_start::sampling_period_ns

@sampling_period_ns: Sampling period in nanoseconds
