STRUCT DC_PROBE_UPDATES(9)

💖 struct dc_probe_updates(9) 💖

okay so bestie, welcome to the Kernel API Manual page for struct dc_probe_updates. This is the absolute set of probes DM wants active — yes, the whole iconic struct. Let's get into it. 💅

🎀 NAME 🎀

struct dc_probe_updates — Absolute set of probes DM wants active.

✨ SYNOPSIS ✨

struct dc_probe_updates {
    struct dc_probe_state probes[MAX_PROBES];
    int probe_count;
};

🌸 Members 🌸

okay so there are exactly two members, and they are lowkey carrying the whole struct:

• probes — desired probe descriptors.
• probe_count — number of valid entries in probes.

🦋 Description 🦋

this struct mirrors the plane/stream absolute-set model: the array is the complete desired set. DC compares it against the committed set to add, remove, or transition probes. periodt. 💖
