i40e_vc_config_irq_map_msg(9)

📦 version 7.3.1, in nixpkgs unstable

✨ i40e_vc_config_irq_map_msg(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're looking at a page from the Linux kernel's own docs, and this one is all about a teeny little function in the i40e driver. let's get into it 🫶

🌸 NAME 🌸

i40e_vc_config_irq_map_msg

...

and that's literally it 😭 the manpage gives us the name and then just ✨nothing✨ — no one-liner, no description, no lore. it's giving mysterious main character energy ngl 💅

🦋 SYNOPSIS 🦋

int i40e_vc_config_irq_map_msg (struct i40e_vf *vf , u8 *msg );

so she takes two args and hands you back an int. int as in the return type, not the vibe. 🔥

🎀 ARGUMENTS 🎀

  • vf — pointer to the VF info 👑 (that's the Virtual Function's info struct, and yeah you gotta hand over a pointer to it, no cap)
  • msg — pointer to the msg buffer 📨 (the message buffer — the actual payload lives in there)

both are pointers. both are required. both are iconic. periodt 💜

⭐ DESCRIPTION ⭐

so what does she do? the docs keep it short and sweet: she's called from the VF to configure the irq to queue map.

that's the whole description. that's the whole tea. 🍓 the VF calls in, and this function's job is configuring the mapping between irqs and queues. iykyk 😌

🌈 SEE ALSO 🌈

okay this is the part where the manpage absolutely ate — the SEE ALSO list is genuinely enormous, like she brought her entire friend group to the function 💀 every single one of these lives in the same kernel file:

Kernel file ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c

and here's the full squad, no one left behind 🫶:

like. that's so many. she knows everyone at the party 😭🦋

ngl bestie, if you're actually digging into this one, the SEE ALSO list above is your bestie too — that's where the rest of the i40e virtchnl story lives 👀

and that's the page! 🎀 before you go — this one comes straight out of ./drivers/net/ethernet/intel/i40e in the Kernel API Manual, dated October 2026, and she's filed as i40e_vc_config_irq_map_msg(9). slay, go configure some irq maps 💅✨
