💅 radeon_vm_clear_freed(9) — like, the Kernel API Manual page, bestie 🎀

okay so bestie, welcome to the glow-up of radeon_vm_clear_freed(9), straight out of the Kernel API Manual ✨ this one's about tidying up your page tables so freed BOs don't just vibe there forever being messy. it's giving "clean your room before company comes over" energy, and honestly? iconic.

✨ NAME ✨

radeon_vm_clear_freed — clear freed BOs in the PT 🧹💖

like, exactly what it says on the tin, no cap.

🌸 SYNOPSIS 🌸

int radeon_vm_clear_freed (struct radeon_device *rdev , struct radeon_vm
*vm );

that's the whole signature, mwah 💋

🦋 ARGUMENTS 🦋

  • rdev — a radeon_device pointer, aka your main character device struct 👑
  • vm — the requested vm, the one you're doing the clearing for 🫶

💜 DESCRIPTION 💜

okay so the whole point: make sure all freed BOs are cleared in the PT. that's it, that's the job. returns 0 for success ⭐ (yes, zero is the good number here, don't let anyone tell you otherwise).

⚠️ but listen — PTs have to be reserved and mutex must be locked! i'm so serious, bestie 😭 this is a real caveat, not a vibe. get your locking situation sorted before you call this, or it's gonna be a bad time. 🔥
