STRUCT PPE_BM_PORT_CONFIG(9)

💅 struct ppe_bm_port_config(9) — the Kernel API Manual glow-up

okay so bestie, welcome to the Kernel API Manual page for struct ppe_bm_port_config 🎀 this is the PPE BM port configuration struct and honestly it's giving "small but booked and busy" ✨

---

🌸 NAME 🌸

struct ppe_bm_port_config — PPE BM port configuration. that's it, that's the name, she's literally that 💅

---

✨ SYNOPSIS ✨

here's the whole struct, no cap, every field exactly as it lives:

struct ppe_bm_port_config {
    unsigned int port_id_start;
    unsigned int port_id_end;
    unsigned int pre_alloc;
    unsigned int in_fly_buf;
    unsigned int ceil;
    unsigned int weight;
    unsigned int resume_offset;
    unsigned int resume_ceil;
    bool dynamic;
 };

---

🦋 Members 🦋

time for the cast, and every single one of them is a main character:

• port_id_start — the fist BM port ID to configure. yes, the first one, first in the lineup 🫶
• port_id_end — the last BM port ID to configure. the closing act, periodt 💖
• pre_alloc — BM port dedicated buffer number. that's her allocated little buffer stash ✨
• in_fly_buf — buffer number for receiving the packet after a pause frame got sent. packets mid-flight, still landing 🦋
• ceil — the ceil that generates the back pressure. pressure? she's applying it 💅
• weight — weight value. the weight ✨
• resume_offset — resume offset from the threshold value. like, how far from the threshold we resume 🎀
• resume_ceil — the ceil to resume from the back pressure state. getting out of that pressure state, slay 🌸
• dynamic — whether the dynamic threshold is used or not. bool behavior, iconic 👑

---

💜 Description 💜

so what's the whole point? this one is for configuring the threshold that impacts the port flow control 🔥 that's the vibe, that's the job.
