vme_dma_free(9)

💖 vme_dma_free — Kernel API Manual energy 💖

okay so bestie, welcome to the Kernel API Manual page for vme_dma_free. this is the cleanup era for a VME DMA resource — it’s giving “return the borrowed hoodie, but make it kernel business.” 🧺✨

🎀 NAME 🎀

vme_dma_free — Free a VME DMA resource. periodt. 💅

📜 SYNOPSIS 📜

int vme_dma_free (struct vme_resource *resource );

🧸 ARGUMENTS 🧸

• resource — pointer to VME DMA resource. that’s the cutie you’re passing in to get freed. 🫶

💖 DESCRIPTION 💖

Free the provided DMA resource so that it may be reallocated. no cap, that’s the whole plot: the resource gets freed up and can be reallocated later. ♻️✨

🔥 RETURN 🔥

• Zero — on success. slay. 💚
• -EINVAL — on invalid VME resource. not the vibe. 🙈
• -EBUSY — if resource is still active. busy bestie means it’s not free yet. 💀
