i40e_read_bw_from_alt_ram(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

i40e_read_bw_from_alt_ram — bestie, the description line upstream is literally empty 💀 so I'm not gonna invent one for you. The name itself is doing all the talking here: it reads bandwidth from the alternate RAM. That's it, that's the whole vibe check 🎀

(This is a page straight out of the Kernel API Manual, section 9, so you know it's the driver-internals kind of party 🧚)

🌸 SYNOPSIS 🌸

int i40e_read_bw_from_alt_ram (struct i40e_hw *hw , u32 *max_bw , u32
       *min_bw , bool *min_valid , bool *max_valid );

okay so it's giving "returns an int" and it takes five things. Five!! We love a function with a whole friend group 🫶

💅 ARGUMENTS 💅

  • hw — pointer to the hardware structure. Your main character struct, the one everything else is a pointer into ✨
  • max_bw — pointer for max_bw read. Yes, it's a pointer to where the max bandwidth read lands 🔥
  • min_bw — pointer for min_bw read. Same energy, but minimum 🍓
  • min_valid — pointer for the bool that is true if min_bw is a valid value 👑 (so like, read the flag before you trust the number, iykyk)
  • max_valid — pointer for the bool that is true if max_bw is a valid value ⭐ (same deal, other side)

🦋 DESCRIPTION 🦋

Read bw from the alternate ram for the given pf 💖

That's the entire description. Short, sweet, and honestly a little mysterious — the manpage said what it said and then dipped 🙈 No cap, that's all the detail we get.

🌈 SEE ALSO 🌈

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

And now, the moment you've all been waiting for: the entire i40e extended fam 😭 (yes this is the whole list, I would never do you dirty by trimming it):

And that's the whole page, bestie — no skipped options, no deleted references, we keep it 100 around here 💜

Source/version: ./drivers/net/ethernet/intel/i40e · dated October 2026 — the i40e_read_bw_from_alt_ram(9) girlies stay winning 🎀✨ slay, go read some bandwidth 💅
