zynqmp_dma_probe(9)

💖 zynqmp_dma_probe — Driver probe function 💖

okay so this is a page from the Kernel API Manual bestie, and it's about one single function: zynqmp_dma_probe. That's it. That's the whole vibe. It's the probe function for the driver, and she's short, she's sweet, and honestly she ate. ✨

---

🌸 SYNOPSIS 🌸

like, here's the whole signature, no cap:

int zynqmp_dma_probe (struct platform_device *pdev );

it returns an int and takes exactly one argument. that's the entire API. iconic minimalism tbh. 💅

🎀 ARGUMENTS 🎀

• pdev — pointer to the struct platform_device structure. literally just a pointer to the platform device struct, that's all she needs from you 🫶

⭐ RETURN ⭐

bestie. i have to be so fr fr with you rn. the RETURN section on this page is completely empty. like, nothing. not a single word. no exit codes, no 0 on success, no negative errno, nada. 😭 so i'm not gonna sit here and make something up — there is genuinely no documented return value here. if you need it, go read the source (which is right down there 👇). i'm not about to invent facts, that's not the vibe. 💀

🌈 SEE ALSO 🌈

okay this is the main character section, buckle up. she lists everything. every sibling, every cousin, the whole family group chat:
