ENUM DC_PROBE_TARGET_STATE(9)

💖 NAME 💖

okay bestie, welcome to enum dc_probe_target_state(9) — the Kernel API Manual page for the target lifecycle state that DM wants DC to reach. it’s giving “final form” energy ✨

✨ SYNOPSIS ✨

enum dc_probe_target_state {
    DC_PROBE_NOT_MEASURING ,
    DC_PROBE_MEASURING ,
    DC_PROBE_MEASURED

};

🎀 Constants 🎀

• DC_PROBE_NOT_MEASURING — probe is inactive, so no valid data is available. literally nothing to read, bestie.
• DC_PROBE_MEASURING — the probe runs continuously. The latest value can be read back at any time and may differ on each read. so yes, every read can be a whole new vibe.
• DC_PROBE_MEASURED — the probe performed one shot. The result is latched and stays valid until DM transitions back to DC_PROBE_NOT_MEASURING. locked in, periodt.

🦋 Description 🦋

DM sets this to describe the final state DC must reach by the end of the commit. DC performs whatever HW transition sequence is needed. that’s the assignment, and DC handles the HW transition sequence 🌸
