t4_sge_stop(9)

🎀 NAME 🎀

t4_sge_stop — disable SGE operation. This is the t4_sge_stop(9) page from the Kernel API Manual, and yes bestie, it’s a tiny one but it’s doing important main character work. 💅

✨ SYNOPSIS ✨

void t4_sge_stop (struct adapter *adap );

🫶 ARGUMENTS 🫶

• adap — the adapter. That’s the whole argument, no cap. 💖

🌸 DESCRIPTION 🌸

Okay so this function stops the tasklets and timers associated with the DMA engine. Slay. 🦋

Heads up though: it’s effective only if measures have been taken to disable any HW events that may restart them. So like, do the HW-event shutdown first, bestie — otherwise they can just come right back. 😭

k bye 💖 this iconic little page came from the Kernel API Manual, source/version line ./drivers/net/ethernet/chelsio..., dated October 2026, still serving t4_sge_stop(9) realness. 🎀✨
