✨ dfl_fpga_cd...fig_ports_vf — Kernel API Manual ✨

okay so bestie, we're in the <pink>dfl_fpga_cd...fig_ports_vf(9)page of the Kernel API Manual (yes that's the real truncated title, the header literally saysdfl_fpga_cd...fig_ports_vf(9)` and I refuse to gaslight you about it) 💅

🌸 NAME 🌸

dfl_fpga_cdev_config_ports_vf — configure ports to VF access mode 🦋

---

💖 SYNOPSIS 💖

int dfl_fpga_cdev_config_ports_vf (struct dfl_fpga_cdev *cdev , int
num_vfs );

like, that's the whole vibe. two args, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

• cdev — the parent container device, aka the main character 👑
• num_vfs — the VF device number, fr fr it's just a number 🔢

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — this function is needed in the sriov configuration routine. like, it's not optional, it's part of the routine, periodt.

what it does: it can be used to configure the released ports from PF access mode over to VF. that's it, that's the whole job ✨

ngl the original says "configure the released ports from PF access mode to VF" — so if you're looking for the PF side of things, this is not that function, bestie 🙈

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code otherwise 😭
