okay bestie, welcome to the ipc4_probes_points_info(9) page from the Kernel API Manual ✨ it’s all about retrieving probe-point info, and we’re keeping every single detail — no cap.

💖 NAME 💖

ipc4_probes_points_info - retrieve list of probe points. That’s the whole assignment. 💅

✨ SYNOPSIS ✨

int ipc4_probes_points_info (struct sof_client_dev *cdev , struct
sof_probe_point_desc **desc , size_t *num_desc , enum
sof_probe_info_type type );

🎀 ARGUMENTS 🎀

• cdev — the SOF client device. That’s the device we’re talking to, bestie.
• desc — the returned list of active probes. This is where the list comes back.
• num_desc — the returned count of active probes. You get the number right here.
• type — either PROBES_INFO_ACTIVE_PROBES or PROBES_INFO_AVAILABE_PROBES. Yup, AVAILABE is spelled exactly like that in the constant — iykyk 🫶

🔥 RETURN 🔥

0 on success, and a negative error code on error. Slay when it’s zero, 😭 when it’s negative.
