e1000e_put_hw_semaphore(9)

💅 e1000e_put_hw_semaphore(9) — Kernel API Manual, but make it cute

okay so bestie, welcome to the e1000e_put_hw_semaphore(9) page 💖 this one lives in the Kernel API Manual and honestly? she's short, she's sweet, she's the goodbye half of a handshake. let's get into it ✨

---

🌸 NAME

e1000e_put_hw_semaphore — release the hardware semaphore 🎀

like, you're done with the thing, so you give it back. that's the whole vibe.

---

✨ SYNOPSIS

void e1000e_put_hw_semaphore (struct e1000_hw *hw );

no return value, no drama, no notes. she just does it 💅

---

🫶 ARGUMENTS

• hw — pointer to the HW structure 💖 that's your hardware struct, the little passport she needs to know which NIC's semaphore you're handing back.

---

🔥 DESCRIPTION

Release hardware semaphore used to access the PHY or NVM 👑

okay so context, because i know you're wondering: that semaphore is the little "occupied!! 🙈" sign that stops two things from poking the PHY or the NVM at the same time. you grab it with the getter, you do your business, and then — this function — you release it. freeing it. letting the next girlie in. no cap, it's just the polite thing to do 🧚
