STRUCT PPE_PORT_SCHEDULE_RESOURCE(9)

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

okay so bestie, welcome to the Kernel API Manual entry for struct ppe_port_schedule_resource and honestly? it's giving "little struct that could" ✨ this is the PPE port scheduler resource, and we're gonna go through every single field together, no skipping, no cap 🫶

🌸 NAME 🌸

struct ppe_port_schedule_resource — the PPE port scheduler resource. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

here's the whole struct, laid out exactly as it is, don't touch anything:

struct ppe_port_schedule_resource {
    unsigned int ucastq_start;
    unsigned int ucastq_end;
    unsigned int mcastq_start;
    unsigned int mcastq_end;
    unsigned int flow_id_start;
    unsigned int flow_id_end;
    unsigned int l0node_start;
    unsigned int l0node_end;
    unsigned int l1node_start;
    unsigned int l1node_end;
 };

look at her. ten unsigned ints. iconic. 👑

🎀 Members 🎀

okay so this is the part where we meet everyone in the group chat 💅

• ucastq_start — the unicast queue start ID. where the unicast queue party begins 🎉
• ucastq_end — the unicast queue end ID. where it wraps up, bye bestie 👋
• mcastq_start — the multicast queue start ID. multicast's turn to shine ✨
• mcastq_end — the multicast queue end ID. and that's a wrap on multicast 🌈
• flow_id_start — the flow start ID. first flow in the lineup 🧚
• flow_id_end — the flow end ID. last flow, slay 💜
• l0node_start — the scheduler node start ID for the queue level. lowkey the queue-level starting point 🔥
• l0node_end — the scheduler node end ID for the queue level. and the queue-level finish line 🏁
• l1node_start — the scheduler node start ID for the flow level. flow-level starting point, main character energy 💫
• l1node_end — the scheduler node end ID for the flow level. flow-level end point, periodt 💅

🦋 Description 🦋

so what is this whole thing actually for? it's the PPE scheduler resource that gets allocated among the PPE ports. that's the whole description, and honestly it ate 🌸

ngl bestie, that ./drivers/net/ethernet/qualcom... path in the footer is literally truncated in the source, so i'm leaving it exactly as it is — don't come for me 🙈

okay and finally, the cute little sign-off 🎀 this page lives at ./drivers/net/ethernet/qualcom... and is dated October 2026, and it's page struct ppe_...ule_resource(9) — thanks for reading, mwah 💖✨🦋
