STRUCT DRM_I915_QUERY_GUC_SUBMISSION_VERSION(9)

💅 struct drm_i915_query_guc_submission_version — a Kernel API Manual moment 🎀

okay bestie, welcome to the Kernel API Manual page for struct drm_i915_query_guc_submission_version, and no cap, this one is short and sweet. It's giving "little struct, big responsibility" energy — it's literally just the four numbers that tell you which GuC submission interface version you're dealing with. iconic. let's get into it ✨

✨ NAME ✨

struct drm_i915_query_guc_submission_version — query GuC submission interface version 🦋

like, that's the whole thing. the struct exists so you can ask "hey what version of the GuC submission interface am I working with" and get an actual answer. obsessed.

🌸 SYNOPSIS 🌸

struct drm_i915_query_guc_submission_version {
    __u32 branch;
    __u32 major;
    __u32 minor;
    __u32 patch;
 };

look at her. four little __u32 fields, all stacked up, all vibes. 🫶

🧚 Members 🧚

• branch — the firmware branch version. that's it, that's the field 💜
• major — the firmware major version. main character number fr fr 👑
• minor — the firmware minor version. lowkey important, don't sleep on her 🌸
• patch — the firmware patch version. the final lil sprinkle 🍓

bestie note: all four are plain __u32 values — no pointers, no trickery, no "not me" moments. just numbers. slay. 💅

this lil rewrite came from ./tools/perf/trace/beauty/incl..., dated October 2026, and the original footer still calls her struct drm_i...sion_version(9) — same girl, same manual, same energy. mwah 🎀✨
