e1000_get_hw...aphore_82573(9)

👑 e1000_get_hw_semaphore_82573 — from the Kernel API Manual ✨

okay so bestie, welcome to the glow-up of e1000_get_hw_semaphore_82573(9) — that's the page title and the manual name, we're folding it in right here at the top so it doesn't get lonely 🫶. This is a kernel API manual page, which means it's documenting a C function inside the Linux kernel, and it is short, so let's not waste a single crumb of it 💅.

---

✨ NAME ✨

e1000_get_hw_semaphore_82573 — Acquire hardware semaphore. that's it. that's the whole name section. iconic minimalism honestly.

---

🌸 SYNOPSIS 🌸

here's the signature, verbatim, no notes:

s32 e1000_get_hw_semaphore_82573 (struct e1000_hw *hw );

so it returns an s32 (that's a 32-bit signed integer, iykyk) and takes exactly one argument. one. single. pointer. main character energy 🎀

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💖 that's literally the whole description. it's a pointer, it points at the hardware structure, and that's what you're handing over. no cap.

---

⭐ DESCRIPTION ⭐

okay so what does it do? it acquires the HW semaphore during reset. that's the vibe. that's the function. during a reset, this thing goes and grabs the hardware semaphore 🔥

ngl the manpage does not elaborate further, and I'm not about to invent lore. that's the fact, fr fr.

and that's the page!! 💀 sign-off time: this lil beauty comes from the source path ./drivers/net/ethernet/intel/e... (yes it's abbreviated like that on the page, don't come for me) and it's dated October 2026 — and the running footer repeats the title e1000_get_hw...aphore_82573(9) because manpages love a good echo 🧚 go acquire that semaphore bestie, you got this 💖✨
