💖 t4_early_init(9) — the "bestie wake up the NIC" page 💖

okay so this is a page from the Kernel API Manual, and it's about t4_early_init — shoutout to the manual, love her 💅

✨ NAME ✨

t4_early_init — the moment you politely ask the FW (firmware, bestie, keep up) to initialize the device 🫶

⭐ SYNOPSIS ⭐

int t4_early_init (struct adapter *adap , unsigned int mbox );

like yes that's the whole signature, she's compact and she's iconic ✨

🎀 ARGUMENTS 🎀

  • adap — the adapter 💜 like, the device we're doing all this for
  • mbox — the mailbox to use for the FW command 📬 (yes it goes in the mailbox, that's the whole bit)

🌸 DESCRIPTION 🌸

so what this does: it issues a command to FW to partially initialize the device. lowkey huge of it.

the tea is that this handles the initialization that generally doesn't depend on user input — no cap, it's the stuff that just needs to happen on its own before anyone's opinions get involved 🙈

key word is partially, ok? don't come for her about the rest of the init, that's not her job 💀

🦋 SEE ALSO 🦋

the whole friend group, fr fr — plus the kernel file she lives in:

  • Kernel file ./drivers/net/ethernet/chelsio/cxgb4/t4_hw.c

and now the cast, in order, no skips 👑

ngl that's a long SEE ALSO and I respect every single one of them 💀💖

and that's the page!! 🎀 source/version line says ./drivers/net/ethernet/chelsio... and it's dated October 2026 — so she's from the future, main character energy fr ✨👑 go read the source, mwah 💅💜
