xe_step_pre_gmdid_get(9)

💅 xe_step_pre_gmdid_get(9) — like, the pre-GMD_ID stepping era, bestie

okay so grab a snack 🍓 because we're diving into the Kernel API Manual, and this one's a little function with a big job. No cap, it's the one that reads your PCI revid and tells you what IP stepping you're actually on. Main character energy fr. ✨

🌸 NAME 🌸

xe_step_pre_gmdid_get — literally just Determine IP steppings from PCI revid. That's the whole vibe check. 🎀

---

✨ SYNOPSIS ✨

void xe_step_pre_gmdid_get (struct xe_device *xe , struct xe_step_info *step );

that's it. two args, void return, no drama. 💅

---

💖 ARGUMENTS 💖

• xe — your Xe device 🖥️ like, the actual thing we're asking about
• step — Pointer to the step struct to update 🫶 she gets updated in place, so make sure she's ready for it

---

🦋 DESCRIPTION 🦋

okay so the whole gig here is: take that PCI revid you're holding and convert it into proper IP steppings, then update step->basedie, step->graphics and step->media accordingly. all three, together, slay. 🔥

⚠️ but bestie, listen — this should only be used on platforms that do not have GMD_ID support. like, do not come for this function if your platform has GMD_ID. it's giving "wrong tool for the job" and we don't do that here. 💀
