💅 e1000e_get_hw_semaphore(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for this lil kernel function 🫶. It's giving "small function, very important semaphore business" energy, and we're gonna get into all of it. no cap.

🌸 NAME 🌸

e1000e_get_hw_semaphore — acquire the hardware semaphore ✨

---

🎀 SYNOPSIS 🎀

s32 e1000e_get_hw_semaphore (struct e1000_hw *hw );

---

💖 ARGUMENTS 💖

• hw — pointer to the HW structure 👑

---

🦋 DESCRIPTION 🦋

soooo the vibe here is: this function acquires the HW semaphore so you can access the PHY or the NVM 💅. That's the whole assignment, and it ate. literally just grab that hardware semaphore and make PHY/NVM access happen.
