ixgbe_acquir...ync_x550em_a(9)

💅 ixgbe_acquir...ync_x550em_a(9) — Kernel API Manual 🎀

okay so bestie, welcome to the group chat for a little kernel function. this is a §9 kernel API page from the Kernel API Manual, and honestly? it's giving "small function, huge friend group." let's get into it ✨

---

✨ NAME ✨

ixgbe_acquire_swfw_sync_x550em_a — grab the SWFW semaphore. that's the whole vibe. it acquires. it syncs. it slays 💅

---

🌸 SYNOPSIS 🌸

int ixgbe_acquire_swfw_sync_x550em_a (struct ixgbe_hw *hw , u32 mask );

return type is int, bestie — so like, it comes back with an answer 🫶

---

🦋 ARGUMENTS 🦋

• hw — a pointer to the hardware structure. like, the actual hardware. the main character of the operation 👑
• mask — the mask that specifies which semaphore to acquire. not all of them, bestie. the one you asked for. precision 💅

---

💖 DESCRIPTION 💖

okay so here's the tea: this function acquires the SWFW semaphore and then gets the shared PHY token as needed. that's it. that's the whole plot. no cap, that's literally what it does — it grabs the semaphore, and if the shared PHY token is needed, it gets that too. iconic behavior honestly 🎀

and that's the page, bestie! 💖 this one's from the kernel source under ./drivers/net/ethernet/intel/i... and it's dated October 2026 — so like, future-dated and still iconic. mwah 🫶💅✨
