🫶 e1000_configure_k1_ich8lan(9) 🫶

okay bestie, this one’s straight out of the Kernel API Manual, and it’s giving “tiny function, very specific power-state business” energy. let’s get into it 💅

---

🌸 NAME 🌸

e1000_configure_k1_ich8lan — configure K1 power state ✨

---

🦋 SYNOPSIS 🦋

s32 e1000_configure_k1_ich8lan (struct e1000_hw *hw , bool k1_enable );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure, iconic, necessary, we love her 🫶
• k1_enable — the K1 state to configure, literally the whole vibe check for this call 💖

---

✨ DESCRIPTION ✨

so basically: configure the K1 power state based on the provided parameter. that’s the assignment, and it ate 🔥

important caveat, no cap: it assumes the semaphore is already acquired. like, don’t come in here without your semaphore, bestie 😭

return vibe check: success returns 0; failure returns -E1000_ERR_PHY (-2) 💀
