ixgbe_hic_unlocked(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_hic_unlocked — a.k.a. the Kernel API Manual page, but make it make sense 💖

okay so bestie, this is the manual page for ixgbe_hic_unlocked(9) from the Kernel API Manual, and honestly? it's giving "tiny function, huge friend group." let's get into it ✨

✨ NAME ✨

ixgbe_hic_unlocked — the one that issues a command to the manageability block, unlocked-style 🫶

🦋 SYNOPSIS 🦋

int ixgbe_hic_unlocked (struct ixgbe_hw *hw , u32 *buffer , u32 length ,
u32 timeout );

like, that's the whole signature, no notes 💅

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. bestie's whole identity lives in here 🌸
  • buffer — the command you wanna write, and where the return status gets dropped off after. multitasking icon 👑
  • length — how long buffer is. must be a multiple of 4 bytes, no cap, that's a hard requirement 😤
  • timeout — how long (in ms) you're willing to sit there waiting for the command to finish. patience is a virtue fr fr ⏳

🔥 DESCRIPTION 🔥

so basically this function communicates with the manageability block 🗣️✨. if it goes well you get 0 back. if not, here's the vibe check:

  • returns a semaphore error when it hits an error acquiring the semaphore (rude 😭)
  • returns -EINVAL when you pass in incorrect parameters (wrong vibes, invalid input 💀)
  • returns -EIO when the command itself fails (it just didn't ate 🤷‍♀️)
⚠️ important caveat bestie, do not skip this: this function assumes that the IXGBE_GSSR_SW_MNG_SM semaphore is held by the caller. like, it's not gonna grab it for you. you gotta already be holding it. main character responsibility 🔑💅

🌈 SEE ALSO 🌈

the whole squad 🫶 — first up, the kernel file where all this lives:

Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_common.c

and now the full friend group, in order, nobody left behind:

like, that's the whole group chat, everyone got a mention 💜

and that's the page!! source/version vibes come from ./drivers/net/ethernet/intel/i... and the date stamp says October 2026 🗓️✨ — so yeah, this doc is from the future, slay. bye bestie, go hold that semaphore 🫶💅🎀
