✨ ice_vf_cfg_q_quanta_profile(9) ✨

okay so real talk, bestie — this is a page from the Kernel API Manual, and it's all about ice_vf_cfg_q_quanta_profile, which honestly is giving "the function that decides how much quanta pie each slice gets" 🥧💅. Buckle up, it's actually not that deep, i promise.

🌸 NAME 🌸

ice_vf_cfg_q_quanta_profile — configure quanta profile, periodt. that's literally the whole vibe.

---

🎀 SYNOPSIS 🎀

int ice_vf_cfg_q_quanta_profile (struct ice_vf *vf , u16 quanta_size ,
       u16 *quanta_prof_idx );

like, it takes one struct pointer, a u16, and a pointer to a u16, and it gives you back an int. iconic signature tbh 🫶

---

🦋 ARGUMENTS 🦋

• vf — pointer to the VF info 💖 like, this is the whole personality of the thing we're configuring
• quanta_size — quanta size to be set ✨ the actual number going in
• quanta_prof_idx — pointer to the quanta profile index 🎯 you hand it over, it points at the index, slay

---

🔥 DESCRIPTION 🔥

so what does it do? it chooses an available quanta profile and configures the register 🧚 no cap, that's the whole job.

here's the tea about how the quanta profile works: it's evenly divided by the number of device ports, and then it's available to the specific PF and VFs 💜. the first profile for each PF is a reserved default profile — like, that one's taken, don't touch it 🙈. only quanta size of the rest unused profile can be modified. and yes that grammar is the original's, i'm just the messenger 💀

ngl the important part is: default profile = hands off. only the unused ones are up for editing ✨

---

⭐ RETURN ⭐

0 on success, or a negative error value if things go sideways 😭 lowkey the standard kernel return vibe fr fr.

a little sign-off moment 🎀

this page came from ./drivers/net/ethernet/intel/i... and the date on it is October 2026. so yeah, it's timestamped, it's canon, and it's still ice_vf_cfg_q_quanta_profile(9). bye bestie, go configure some quanta 💖✨🦋
