t3_sge_start(9)

💅 t3_sge_start(9) — like, the Kernel API Manual moment we've all been waiting for

okay bestie, buckle up, because today we're deep in the Kernel API Manual and the star of the show is t3_sge_start 🎀 this is a Linux kernel function, it lives in ./drivers/net/ethernet/chelsio/cxgb3/sge.c, and it is literally the glow-up that makes packet transfers finally happen. slay.

---

✨ NAME ✨

t3_sge_start — enable SGE 🌸

like yes, that's the whole name section, it's giving minimalist icon behavior and honestly? obsessed.

---

🦋 SYNOPSIS 🦋

void t3_sge_start (struct adapter *adap );

no cap, that's the entire signature. it returns void, so don't be out here expecting a little return value to text you back 💀 it takes exactly one (1) argument and then it's done.

---

🌈 ARGUMENTS 🌈

• adap — the adapter 💖 that's it, that's the whole parameter list. one adapter, hand-delivered, ready to get switched on.

---

🔥 DESCRIPTION 🔥

so here's the tea ☕: t3_sge_start enables the SGE for DMAs. periodt.

and the way that this is the last step in starting packet transfers?? main character energy fr fr. everything else has already been lined up before this call, and t3_sge_start is the one that walks in at the end, flips the switch, and goes "okay we're live" ✨

no hidden extras here bestie — the docs say exactly this and nothing more, so don't go inventing side quests for it 🙈

and that's the page, bestie 🍓 before you go — the source/version line at the bottom reads ./drivers/net/ethernet/chelsio... with a date of October 2026, and the whole thing is filed under t3_sge_start(9) in the Kernel API Manual. go enable that SGE, you absolute icon 🧚💜
