vga_tryget(9)

💖 NAME 💖

okay so welcome to the vga_tryget(9) page from the Kernel API Manual, bestie 💅 and the name is literally giving: try to acquire & lock legacy VGA resources 🌸

---

✨ SYNOPSIS ✨

int vga_tryget (struct pci_dev *pdev , unsigned int rsrc );

---

🎀 ARGUMENTS 🎀

• pdev — the PCI device of the VGA card, or NULL for the system default 🫶
• rsrc — a bit mask of the resources to acquire and lock ✨

---

🦋 DESCRIPTION 🦋

So like, it performs the same operation as vga_get, but instead of blocking when the resources are already locked by another card, it returns an error (-EBUSY) 💀 no waiting around, no cap.

It can be called in any context 👑

On success, release the VGA resource again with vga_put 🎀

Return situation: 0 on success, negative error code on failure 😭
