📦 version 7.3.1, in nixpkgs unstable

💖 vmw_bo_pin_in_vram_or_gmr(9) — the "put this buffer in vram or gmr" moment 💖

Okay bestie, welcome to the Kernel API Manual entry for vmw_bo_pin_in_vram_or_gmr. Yes that's a mouthful, but it's literally just a helper that moves a buffer over to vram or gmr, and we're gonna get through it together 🫶

✨ NAME ✨

vmw_bo_pin_in_vram_or_gmr — Move a buffer to vram or gmr. That's the whole vibe. No cap.

🌈 SYNOPSIS 🌈

int vmw_bo_pin_in_vram_or_gmr (struct vmw_private *dev_priv , struct
       vmw_bo *buf , bool interruptible );

Look at that signature slaying exactly as written. Don't touch it, don't "fix" the spacing, just appreciate it 💅

🎀 ARGUMENTS 🎀

  • dev_priv — Driver private. It's the driver's own little private stash, iykyk.
  • buf — DMA buffer to move. The actual buffer being moved, main character energy fr.
  • interruptible — Use interruptible wait. Set this and the wait is interruptible; that's the whole thing 👑

🦋 DESCRIPTION 🦋

So here's what happens, bestie: this function takes the reservation_sem in write mode. Yeah. Write mode. It's not playing around.

Then it flushes and unpins the query bo to avoid failures. That's it, that's the description — flushes it, unpins it, avoids the failures, periodt ✨

🌸 RETURN 🌸

  • Zero on success — slay 💖
  • Negative error code on failure.
  • In particular -ERESTARTSYS if it gets interrupted by a signal 😭 that's the one to remember.
