🌸 NAME 🌸

ixgbe_acquire_swfw_sync_X540 — literally just grabs the SWFW semaphore for you, no cap 👑

🦋 SYNOPSIS 🦋

int ixgbe_acquire_swfw_sync_X540 (struct ixgbe_hw *hw , u32 mask );

like, it returns an int, takes your hardware struct and a mask, and goes and gets the semaphore. that's the whole vibe 💫

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure. yes queen, hand over the whole hardware situation 🙈
  • mask — Mask to specify which semaphore to acquire. so like, which one you're claiming — pick your fighter 💅

💖 DESCRIPTION 💖

Acquires the SWFW semaphore through the SW_FW_SYNC register for the specified function (CSR, PHY0, PHY1, NVM, Flash) 🔥

so basically the software/firmware handshake gets locked down for whichever of those five things you named in the mask, and then it's yours to play with. main character energy fr fr 👑

ngl if you grabbed the semaphore you probably wanna go look at ixgbe_release_swfw_sync_X540(9) next 👀 just saying, symmetry is iconic 💀
