intel_wopcm_init_early(9)

💅 intel_wopcm_init_early — kernel API manual, but make it make sense

okay so bestie, welcome to the <pink>intel_wopcm_init_early</pink>(9) page, straight out of the Kernel API Manual. yes, the manual name goes right here at the top, we're being ✨proper✨ about it. this is the group chat briefing on the WOPCM situation, and honestly? it's short, it's sweet, and it's giving "tiny function, big responsibilities." 🎀

🌸 NAME 🌸

intel_wopcm_init_early — the early initialization of the WOPCM, bb. it does the setup stuff first, before everybody else shows up. 🦋

---

✨ SYNOPSIS ✨

void intel_wopcm_init_early (struct intel_wopcm *wopcm );

that's it. that's the whole mood. no return value, she just goes in and does her thing. 💅

---

🫶 ARGUMENTS 🫶

• wopcm — a pointer to intel_wopcm. that's the whole description, no cap. it's literally a pointer to a struct intel_wopcm, and that's what you hand her. 🤲

---

👑 DESCRIPTION 👑

so what's the actual tea? intel_wopcm_init_early sets up the size of the WOPCM, okay? that size is what's gonna get used later on when the WOPCM partitioning happens. so like — she's not doing the partitioning herself, she's the main character who puts the number in place so the later partitioning step has something to work with. setting the stage. iconic behavior. ⭐

think of it as: early init = figure out how big, later = actually carve it up. she does the first part, and she does it early, hence the name. iykyk. 🔥

heads up bestie: this is the early one. the partitioning comes later. don't get it twisted, she is not doing the partitioning. 💀

• Kernel file ./drivers/gpu/drm/i915/gt/intel_wopcm.c — like, the actual source file, go read it if you want the vibes in code form
• WOPCM Layout(9) — the layout page, for when you need the whole picture
• intel_wopcm_init(9) — her sibling function, the one that isn't the early one ✨

and that's the page!! 🧚💜 this lil beauty lives in ./drivers/gpu/drm/i915/gt, dated October 2026, and yes, the footer says intel_wopcm_init_early(9) one more time just to remind you who the main character is. mwah 💋 🍓
