ibmveth_get_desired_dma(9)

💖 NAME 💖

okay so bestie, this is ibmveth_get_desired_dma from the Kernel API Manual — and it literally exists to calculate IO memory desired by the driver. no cap, that’s the whole vibe 💅✨

---

✨ SYNOPSIS ✨

the signature is giving very “one job, done well”:

unsigned long ibmveth_get_desired_dma (struct vio_dev *vdev );

---

🎀 ARGUMENTS 🎀

• vdev — this is the struct vio_dev for the device whose desired IO mem is to be returned. yes bestie, that exact device, that exact IO mem 🫶

---

🦋 DESCRIPTION 🦋

okay so here’s the tea: the return value is:

Number of bytes of IO data the driver will need to perform well.

that’s it, that’s the whole plot. it’s giving “how many bytes does this driver want so it can slay” 🌸✨

mwah 💋 this whole page came from ./drivers/net/ethernet/ibm, dated October 2026, and it’s ibmveth_get_desired_dma(9) from the Kernel API Manual — bye bestie, go get that IO memory 💜🦋
