💅 i40e_aq_debug_dump(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for i40e_aq_debug_dump. Yes the man page name is literally the function name, and yes this is the deep-lore corner of the i40e driver where you go when you want the firmware to spill its internal tea ☕✨

🌸 NAME 🌸

i40e_aq_debug_dump — (and that's it, the original NAME line is literally just the function name with an empty description, so no cap, there's nothing else hiding there 🫶)

✨ SYNOPSIS ✨

int i40e_aq_debug_dump (struct i40e_hw *hw , u8 cluster_id , u8 table_id
, u32 start_index , u16 buff_size , void *buff , u16 *ret_buff_size , u8
*ret_next_table , u32 *ret_next_index , struct i40e_asq_cmd_details
*cmd_details );

it's giving "one function, ten parameters, zero chill" 💀 but it's fine, we're gonna walk through every single one 👑

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure 🖥️ your main character struct.
  • cluster_id — the specific cluster to dump 🌸 like picking which group chat you're scrolling back through.
  • table_id — the table id within the cluster 📋 because the cluster itself wasn't granular enough, obviously.
  • start_index — the index of the line in the block to read 🔢 where you start reading, bestie.
  • buff_size — dump buffer size 📦 how much room you're giving it.
  • buff — dump buffer 🗃️ the actual place the goodies land.
  • ret_buff_size — the actual buffer size returned 📏 so you know what you really got, not what you asked for.
  • ret_next_table — next block to read ➡️ for when you're doing this in chunks, iykyk.
  • ret_next_index — next index to read ⏭️ same vibe, index edition.
  • cmd_details — pointer to the command details structure, or NULL 🫥 pass NULL and it just handles itself.

🦋 DESCRIPTION 🦋

Dump internal FW/HW data for debug purposes 🔍💖

that's the whole description, and honestly? iconic. it's the "just dump the internals for debug reasons" function of your dreams. no extra promises, no guarantees — it's a debug tool, it does debug things ✨

real talk: this is a debug path into firmware/hardware internals, so keep that in mind — it's not doing your normal everyday networking chores 🧚

🌈 SEE ALSO 🌈

kicking off with the source file itself, because we respect a primary source 📚:

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_common.c

and then the squad, the whole friend group, in exactly the order the page lists them 👑:

like, that's the entire extended universe, and we listed every single one 💜

🌸 that's the whole page bestie, ily, go dump some debug data responsibly 🫶
