genwqe_fir_checking(9)

✨ genwqe_fir_checking(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is called genwqe_fir_checking — it lives in section 9 and it's giving "small function, big consequences" energy fr fr 💅

---

🌸 NAME 🌸

genwqe_fir_checking — Check the fault isolation registers of the card 🫶

---

🎀 SYNOPSIS 🎀

u64 genwqe_fir_checking (struct genwqe_dev *cd );

---

🦋 ARGUMENTS 🦋

• cd — GenWQE device information. that's it, that's the whole argument list, she's low-maintenance 👑

---

💖 DESCRIPTION 💖

so the vibe here is: if this code works ok, you can literally try it out with help of the genwqe_poke tool:

sudo ./tools/genwqe_poke 0x8 0xfefefefefef

and then? now the relevant FIRs/sFIRs should be printed out 😭 and the driver should invoke recovery — like, devices are removed and readded. yes, that's the actual documented behaviour, not a vibe I made up, no cap 🔥

heads up bestie: this is the "if this code works ok" branch. so like, the doc is telling you what should happen — keep that energy in mind before you go poking registers on a real card 🙈
