STRUCT AMDXDNA_DRM_QUERY_TELEMETRY_HEADER(9)

💖 struct amdxdna_drm_query_telemetry_header(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes the actual one, and yes we're reading a struct together, it's gonna be iconic. This page is literally about struct amdxdna_drm_query_telemetry_header, aka the telemetry data header. It's the little header that goes "hi, here's what firmware telemetry version you're dealing with, here's what kind of query this is, and here's where the map table lives." Very demure, very plumbing. 🎀

✨ SYNOPSIS ✨

the whole shape of it, verbatim, no cap:

struct amdxdna_drm_query_telemetry_header {
    __u32 major;
    __u32 minor;
    __u32 type;
    __u32 map_num_elements;
    __u32 map[];
 };

🦋 Members 🦋

• major — the firmware telemetry interface major version number. big-number energy. 👑
• minor — the firmware telemetry interface minor version number. the lowercase sibling of major, she's also here. 💅
• type — the telemetry query type. like, what are we even asking about rn. 🔥
• map_num_elements — the total number of elements in the map table. the headcount. the guest list. 🎀
• map — the element map itself. the flexible-array girlies at the end of the struct, she's got map_num_elements entries and zero chill. ✨

lowkey a vibe check on this one: map[] is a flexible array member, so it lives at the tail of the struct and its size comes from map_num_elements. that's just what the source says — I'm not adding lore, I promise. 🫶

and that's the page!! iykyk. this gem comes to you from ./include/uapi/drm, dated October 2026, and it's filed under struct amdx...metry_header(9) — go off, little truncated manpage name, you ate. 🍓🧚💜
