hfi1_reset_device(9)

okay so bestie, we're looking at hfi1_reset_device(9) from the Kernel API Manual, and it's giving “try to reset the chip if possible” energy. 🦋

✨ NAME ✨

hfi1_reset_device — reset the chip if possible 💅

🌸 SYNOPSIS 🌸

int hfi1_reset_device (int unit );

🎀 ARGUMENTS 🎀

• unit — the device to reset. that's the one we're poking at 🫶

💖 DESCRIPTION 💖

Whether or not the reset works out, we attempt to re-initialize the chip — and yes, it's much like a driver unload/reload. iconic reinit behavior, no cap. 🔥

We clear the INITTED flag so that the various entry points will fail until we reinitialize. so like, the door is locked until we're back online, periodt. 💀

For now, we only allow this if no user contexts are open that use chip resources. read that again bestie: no open user contexts using chip resources, or it's a no-go. ✨

and that's the whole vibe check: the source/version spot is ./drivers/infiniband/hw/hfi1, the date is October 2026, and the page is hfi1_reset_device(9) — bye bestie, slay your resets responsibly 🎀💜
