ice_sched_find_node_by_teid(9)

💖 ice_sched_find_node_by_teid(9) — Kernel API Manual 💖

Okay bestie, welcome to the ice_sched_find_node_by_teid(9) page in the Kernel API Manual. This one is all about finding a Tx scheduler node in the SW DB, and it’s giving “tiny recursive search gremlin” energy. 🧚✨

🌸 NAME 🌸

ice_sched_find_node_by_teid — Find the Tx scheduler node in SW DB

🎀 SYNOPSIS 🎀

struct ice_sched_node * ice_sched_find_node_by_teid (struct
       ice_sched_node *start_node , u32 teid );

🫶 ARGUMENTS 🫶

• start_node — pointer to the starting ice_sched_node struct in a sub-tree.
• teid — node TEID to search.

💅 DESCRIPTION 💅

Okay so this function searches the scheduling tree from the SW DB for a node that matches the TEID. The search is recursive, and it’s restricted by the number of layers it has searched through — it stops at the max supported layer. No cap, except the actual layer cap, iykyk. 🌈

This function needs to be called when holding the port_info->sched_lock — do not skip the lock, bestie. 🔒💅
