ice_aq_get_dflt_topo(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_aq_get_dflt_topo — NAME

ok so this is ice_aq_get_dflt_topo(9) from the Kernel API Manual (section 9, kernel internals bestie 🫶) — and it gets the default scheduler topology. that's the whole vibe. iconic honestly ✨

🌸 SYNOPSIS

int ice_aq_get_dflt_topo (struct ice_hw *hw , u8 lport , struct
       ice_aqc_get_topo_elem *buf , u16 buf_size , u8 *num_branches , struct
       ice_sq_cd *cd );

like yes she takes six args, she's that girl 💅

✨ ARGUMENTS

ok bestie let's go through the cast of characters one by one, no skips:

  • hw — pointer to the HW struct 💖 literally the hardware, the main character
  • lport — logical port number 🎀
  • buf — pointer to buffer 🦋
  • buf_size — buffer size in bytes, like measure her before you put stuff in her
  • num_branches — returns total number of queue to port branches 🌈 this one's an output, she's returning the count
  • cd — pointer to command details structure or NULL 😌 classic cd behavior
fr fr keep track of the order: hw, lport, buf, buf_size, num_branches, cd. don't shuffle them, the compiler will simply end you 💀

👑 DESCRIPTION

Get default scheduler topology, opcode 0x400. that's it. that's the whole description. short and stunning, we love a low-effort queen ✨

ok this list is long long, so buckle up bestie, we're going through the entire friend group 🫶 and ngl this whole crew lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_sched.c:

like… 100+ besties. that's a whole group chat 💀🔥 but every single one of them is linked and every single one matters, no cap.
