vmw_bo_pin_in_vram(9)

🎀 NAME 🎀

okay bestie, this is vmw_bo_pin_in_vram(9) from the Kernel API Manual — and the whole function is literally just Move a buffer to vram. ✨ Slay.

---

✨ SYNOPSIS ✨

no cap, here’s the signature exactly as it is — don’t let the line break jump-scare you:

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

---

💅 ARGUMENTS 💅

• dev_priv — Driver private. (the driver’s private data, periodt)
• buf — DMA buffer to move. (the actual buffer, bestie)
• interruptible — Use interruptible wait. (yes, that exact mode 💖)

---

🦋 DESCRIPTION 🦋

This function takes the reservation_sem in write mode. Then it flushes and unpins the query bo to avoid failures.

That’s the whole vibe check: write-mode reservation_sem, flush + unpin the query bo, no failures please 😭💅

---

🌈 RETURN 🌈

Zero on success, Negative error code on failure. In particular -ERESTARTSYS if interrupted by a signal.

So if you get a negative number, that’s the failure branch — and if a signal interrupts you, expect -ERESTARTSYS. 💀
