fpga_region_get(9)

💖 fpga_region_get(9) — the "gimme that region, exclusively" glow-up 💖

okay so this is a page from the Kernel API Manual, and bestie, it's short but it's mighty. Let's get into it ✨

🌸 NAME 🌸

fpga_region_get — get an exclusive reference to an fpga region

Like, you're claiming it. It's yours now. No sharing, no splitting custody. 👑

---

🦋 SYNOPSIS 🦋

struct fpga_region * fpga_region_get (struct fpga_region *region );

---

🎀 ARGUMENTS 🎀

• region — the FPGA Region struct, aka the thing you're trying to grab 🫶

---

✨ DESCRIPTION ✨

So here's the deal, bestie: the caller should call fpga_region_put when done with region. That's it, that's the whole vibe. You take it, you give it back. Clean, respectful, no drama. 💅

---

💀 RETURN 💀

• fpga_region struct if successful. slay, you got it 🎉
• -EBUSY if someone already has a reference to the region. like... it's taken. back off. 😭
• -ENODEV if can't take parent driver module refcount. ngl, that's the "can't even" of error codes 🙈

---

🌈 SEE ALSO 🌈

Kernel file ./drivers/fpga/fpga-region.c plus the whole friend group:

• __fpga_region_register_full(9)
• __fpga_region_register(9)
• fpga_region_unregister(9)
• fpga_region_init(9)

lowkey the most important part: fpga_region_get and fpga_region_put are a matched set. don't be the person who takes a reference and ghosts it. 💀
