💖 hisi_qm_set_vft(9) — Kernel API Manual, bestie edition 💖

okay so welcome to hisi_qm_set_vft(9), straight out of the Kernel API Manual. She is here to set vft to a qm, and honestly? slay. No cap, this is the page for assigning queues among PF and VFs, and we’re gonna get into it. 🫶

🌸 NAME 🌸

hisi_qm_set_vft — Set vft to a qm. periodt.

✨ SYNOPSIS ✨

int hisi_qm_set_vft (struct hisi_qm *qm , u32 fun_num , u32 base , u32
       number );

🎀 ARGUMENTS 🎀

• qm — the qm we want to set its vft. iconic.
• fun_num — the function number.
• base — the base number of queue in vft.
• number — the number of queues in vft.

🔥 DESCRIPTION 🔥

okay so here’s the tea: this function is always called in the PF driver. She’s used to assign queues among PF and VFs. That’s her whole main character job. 💅

Assign queues A~B to PF with:

hisi_qm_set_vft(qm, 0, A, B - A + 1)

Assign queues A~B to VF with:

hisi_qm_set_vft(qm, 2, A, B - A + 1)

(VF function number 0x2.) 🦋
