xe_step_gmdid_get(9)

✨ xe_step_gmdid_get 💅

okay so bestie, welcome to the Kernel API Manual page for xe_step_gmdid_get — yes that's a mouthful, no we're not shortening it, it's iconic. this one lives in ./drivers/gpu/drm/xe and it is <highkey>so</highkey> much simpler than it looks, i promise 🫶

---

🌸 SYNOPSIS 🌸

void xe_step_gmdid_get (struct xe_device *xe , u32 graphics_gmdid_revid
, u32 media_gmdid_revid , struct xe_step_info *step );

that's it. four args, void return, in and out, done. slay ✨

---

🎀 ARGUMENTS 🎀

• xe — the Xe device. your main character fr, the thing everything else is about 💖
• graphics_gmdid_revid — the value of the graphics GMD_ID register's revid field. yep, the raw number, straight from the register 👑
• media_gmdid_revid — the value of the media GMD_ID register's revid field. same vibe, different IP block 🦋
• step — a pointer to the struct step that's gonna get updated. (the original page says "Poninter" and honestly? Poninter is a valid spelling in this house 🎀) she gets written to, she doesn't ask questions 💅

🌈 DESCRIPTION 🌈

so what does this actually do? it takes those revid fields from the GMD_ID registers, converts them into proper IP steppings, and then updates step->graphics and step->media accordingly. like a glow-up translation layer for register values 😭✨

and here's the part you actually need to remember, bestie — the revid values are currently expected to have consistent meanings on all platforms. so:

• major steppings (A0, B0, etc.) are 4 apart 🍓
• minor steppings (A1, A2, etc.) take the values in between those 🔥

so like, the numbering literally goes A0 → A1 → A2 → A3 → B0. four slots, one major bump. ate and left no crumbs 🌸

ngl, the word "currently" is doing a lot of work in that sentence — the page is telling you this is the expected convention, so don't go building your whole personality on it if the docs ever move 💀
