STRUCT DRM_IVPU_METRIC_STREAMER_START(9)

💖 NAME 💖

okay so bestie, this page is from the Kernel API Manual, and it's all about struct drm_ivpu_metric_streamer_start — Start collecting metric data. periodt. 💅

✨ SYNOPSIS ✨

struct drm_ivpu_metric_streamer_start {
    __u64 metric_group_mask;
    __u64 sampling_period_ns;
    __u32 read_period_samples;
    __u32 sample_size;
    __u32 max_data_size;
 };

🧚 Members 🧚

• metric_group_mask — indicates the metric streamer instance, iykyk. 🎀
• sampling_period_ns — the sampling period, in nanoseconds. ⏱️
• read_period_samples — the number of samples after which user space will try to read the data. Reading the data after a significantly longer period may cause data loss 😭 so don't wait extra-long, fr fr.
• sample_size — the returned size of a single sample, in bytes. 🦋
• max_data_size — the returned max data_size from DRM_IOCTL_IVPU_METRIC_STREAMER_GET_DATA. 👑
