ice_sched_add_node(9)

💖 ice_sched_add_node — the "new node just dropped" moment 💖

okay so this is a page from the Kernel API Manual, section 9 (iykyk) — and it's literally about stuffing a fresh Tx scheduler node into the software database. bestie, it's giving "add to cart" but for kernel data structures 💅

---

✨ NAME ✨

ice_sched_add_node — Insert the Tx scheduler node in SW DB

no cap, that's the whole vibe: it inserts a scheduler node into the SW DB. periodt.

---

🦋 SYNOPSIS 🦋

int ice_sched_add_node (struct ice_port_info *pi , u8 layer , struct
       ice_aqc_txsched_elem_data *info , struct ice_sched_node *prealloc_node
       );

int, four args, zero drama (okay maybe a little drama). 🌸

---

🎀 ARGUMENTS 🎀

• pi — the port information structure 🫶 your main character, the one everything hangs off.
• layer — the scheduler layer of the node, a u8 keeping track of which level of the hierarchy we're on.
• info — the scheduler element information, straight from firmware. that's the tea firmware is spilling ☕
• prealloc_node — a preallocated ice_sched_node struct for the SW DB. like when you bring your own tote bag — someone already did the prep work ✨

---

💜 DESCRIPTION 💜

so literally what it says on the tin: this function inserts a scheduler node to the SW DB. that's it, that's the function. not me being dramatic, the manpage is just built different — confidently minimal, iconic behavior 👑

fr fr, don't sleep on how short this description is. the arguments do the heavy lifting here.
