STRUCT PPE_SCHEDULER_QM_CONFIG(9)

💖 struct ppe_scheduler_qm_config(9) — Kernel API Manual 💖

okay bestie, welcome to the ppe_scheduler_qm_config page, straight out of the Kernel API Manual ✨ this is the struct that holds the PPE arbitration config for the scheduler, and honestly? it's giving "small struct, big job" energy 🎀

---

🌸 NAME 🌸

struct ppe_scheduler_qm_config — PPE arbitration for scheduler config, no cap 💅

---

✨ SYNOPSIS ✨

struct ppe_scheduler_qm_config {
    unsigned int ensch_port_bmp;
    unsigned int ensch_port;
    unsigned int desch_port;
    bool desch_backup_port_valid;
    unsigned int desch_backup_port;
 };

like, that's the whole struct. five fields. tiny icon 👑

---

🦋 Members 🦋

the fields, one by one, iykyk

• ensch_port_bmp — the port bit map for the enqueue scheduler 🗺️ it's a map. of ports. for enqueueing.
• ensch_port — the Port ID that goes to the enqueue scheduler 💌
• desch_port — the Port ID that goes to the dequeue scheduler 📤
• desch_backup_port_valid — a bool telling you whether the dequeue for the backup port is valid or not ✅🙈
• desch_backup_port — the Backup port ID to the dequeue scheduler 🎀

---

💜 Description 💜

so what's the actual vibe? this struct is literally how you configure the scheduler settings for enqueuing and dequeuing packets on the PPE port 🌈 that's the whole thing. enqueue side, dequeue side, and a lil backup port for the dequeue side if you're feeling extra 🫶

---

🌟 SEE ALSO 🌟

go look at the kernel file ./drivers/net/ethernet/qualcomm/ppe/ppe_config.c first, bestie, that's the main character 📁✨

and then the whole friend group:

like, read them all. or at least the ones you need. either way, slay 🌸💀

word of warning bestie: this page is what it is — don't go inventing behaviour for these fields, just configure your scheduler settings and move on 🙈

mwah 💋 that's the page! this cutie came from ./drivers/net/ethernet/qualcom... and it's dated October 2026 🗓️ — big thank-you to whoever shipped it, and remember: struct ppe_scheduler_qm_config(9) forever, periodt 👑💖
