igb_get_hw_semaphore_i210(9)

💖 NAME 💖

okay so this is igb_get_hw_semaphore_i210, and yes bestie, it's living in the Kernel API Manual. Its whole name-and-job situation is Acquire hardware semaphore. That's the assignment. periodt. 💅

✨ SYNOPSIS ✨

s32 igb_get_hw_semaphore_i210 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. like, hand it the hardware struct and let it do its semaphore thing 🫶

🦋 DESCRIPTION 🦋

Acquire the HW semaphore to access the PHY or NVM. That's the whole plot: grab the hardware semaphore, and then you can get at the PHY or the NVM. no extra lore, no side quests, just semaphore business. ✨
