zynqmp_dma_suspend(9)

🎀 zynqmp_dma_suspend(9) — the Kernel API Manual 🎀

Ok bestie, this is the zynqmp_dma_suspend(9) page, and it is lowkey a tiny one. Let's get into it 💅

🌸 NAME 🌸

zynqmp_dma_suspend — suspend method for the driver. That's the whole name vibe, no cap.

✨ SYNOPSIS ✨

int zynqmp_dma_suspend (struct device *dev );

🫶 ARGUMENTS 🫶

• dev — Address of the device structure. Yep, that's the pointer bestie is handing over.

💅 DESCRIPTION 💅

The whole job is honestly iconic in its simplicity: put the driver into low power mode. Driver goes sleepy, power gets conserved, main character energy stays intact. That's it. No extra lore, no dramatic side quest.

🔥 RETURN 🔥

Returns 0 on success and failure value on error. So: success = 0, and if something goes wrong you get a failure value. Simple as that 💀
