radeon_ib_pool_init(9)

💖 radeon_ib_pool_init(9) — from the Kernel API Manual, bestie 🎀

Okay so picture this: you're in the kernel, you're on a radeon driver, and you need a whole pool of memory set up to hold your Indirect Buffers. That's literally this function. It's giving "backstage crew for the GPU" energy — nobody claps for it, but nothing slays without it. ✨

🌸 NAME 🌸

radeon_ib_pool_init — init the IB (Indirect Buffer) pool, no cap 💅

---

🦋 SYNOPSIS 🦋

int radeon_ib_pool_init (struct radeon_device *rdev );

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. That's it, that's the whole guest list. She just wants the device, fr fr. 💜

---

✨ DESCRIPTION ✨

So what she actually does: she initializes the suballocator so it can manage a pool of memory that gets used as IBs (Indirect Buffers). And yes — this applies to all asics. Every single one. Equal opportunity pool-having. 👑

Return vibes:

• Returns 0 on success 🎉
• Returns an error on failure 😭

That's the whole plot, and honestly? Iconic. Short, sweet, does exactly one (1) thing.
