💅 igc_acquire_swfw_sync_i225 — bestie, let's grab a semaphore

okay so this is a page straight out of the Kernel API Manual and it's all about igc_acquire_swfw_sync_i225, which honestly is a lot of syllables but hear me out, it's actually iconic ✨

🌸 NAME 🌸

igc_acquire_swfw_sync_i225 — Acquire SW/FW semaphore 🎀

Like, the whole job. That's it. That's the vibe.

🦋 SYNOPSIS 🦋

s32 igc_acquire_swfw_sync_i225 (struct igc_hw *hw , u16 mask );

it returns an s32, it takes a struct igc_hw * and a u16, and yes the spacing in the original is a little chaotic but we're keeping it exactly as it is because that's the whole point 💅

💖 ARGUMENTS 💖

  • hw — pointer to the HW structure. your main character struct fr fr, everything happens through it 🫶
  • mask — specifies which semaphore to acquire. yes bestie, you gotta say which one. it's not a vibes-based system 😭

✨ DESCRIPTION ✨

so what does it do? it acquires the SW/FW semaphore so you can go access the PHY or the NVM. that's the whole gig 👑

and the mask? it also specifies which port we're acquiring the lock for. so like, the mask is doing double duty — which semaphore, and which port. lowkey efficient, highkey important 🌈

ngl, if you don't pass the right mask you're just out here locking the wrong thing, and nobody wants that energy 🙈

🔥 SEE ALSO 🔥

everything below is linked, no skips, no "eh they'll figure it out" — we're listing all of it because that's what the page does, periodt 💀

like, that's the whole friend group right there 🧚 and they all live under ./drivers/net/ethernet/intel/igc, so you know exactly where to find them 💜

okay that's the page!! shoutout to ./drivers/net/ethernet/intel/igc for being the source, dated October 2026, and remember: semaphores are a shared resource, so acquire responsibly bestie 🍓💅⭐
