ice_sched_set_node_bw_dflt(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_sched_set_node_bw_dflt — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the ice scheduler corner of the kernel, because we are literally about to reset a node's bandwidth rate limit profile back to default and honestly? iconic behaviour. this page lives in the Kernel API Manual and it's giving "small function, big scheduler energy" 🫶

🌸 NAME 🌸

ice_sched_set_node_bw_dflt — set node's bandwidth limit to default. that's it, that's the whole vibe. no cap 💖

✨ SYNOPSIS ✨

int ice_sched_set_node_bw_dflt (struct ice_port_info *pi , struct
       ice_sched_node *node , enum ice_rl_type rl_type , u8 layer_num );

like, copy it exactly bestie, character for character, because the compiler does not care about your feelings 😭

🎀 ARGUMENTS 🎀

  • pi — port information structure. yes it's the port info, she's the main character here, show her some respect 👑
  • node — pointer to the node structure. this is the node we're about to give the default treatment to 🦋
  • rl_type — rate limit type: min, max, or shared. three flavours, pick your girl 💅
  • layer_num — layer number where RL profiles are saved. that's where the profile lives, that's where we're going 🧚

💖 DESCRIPTION 💖

so what does she actually DO? this function configures the node element's BW rate limit profile ID — of type CIR, EIR, or SRL — to default. periodt. that's the assignment and she ate 🔥

⚠️ okay this is the important part, do NOT skip it: this function needs to be called with the scheduler lock held. like, actually held. not "I think I held it", not "my friend held it". HELD. fr fr, respect the lock 🙈

🌈 SEE ALSO 🌈

the whole extended friend group, in all her glory — every single one of these, no skipping 💜

that's the whole page bestie, go forth and set some default bandwidth limits responsibly 💙
