💅 igc_acquire_nvm_i225 — a kernel API manual page (section 9, bestie)

okay so real talk, this is a section 9 kernel API page from the Linux manual, and it's about yeeting your way into the EEPROM like you own the place. Let's go ✨

🌸 NAME 🌸

igc_acquire_nvm_i225 — bestie's official job is to Acquire exclusive access to EEPROM. iconic behavior, no cap 💅

✨ SYNOPSIS ✨

s32 igc_acquire_nvm_i225 (struct igc_hw *hw );

that's the whole call, she's short and she knows it 🎀

💖 ARGUMENTS 💖

  • hw — pointer to the HW structure 🫶 literally the hardware struct, that's it, that's the whole argument

🔥 DESCRIPTION 🔥

okay so picture this: you need the EEPROM all to yourself, right? So this function goes and acquires the necessary semaphores for exclusive access to the EEPROM 🙈✨

Then it sets the EEPROM access request bit and waits for the EEPROM access grant bit — like sending a text and then staring at the screen waiting for those three dots to show up 😭 the tension is real

If the access grant bit is set, it returns successful 💖 slay

If it's not set? Then it clears the request for EEPROM access and returns -IGC_ERR_NVM (-1) 💀 not the vibe, but at least it cleans up after itself, we respect that

ngl bestie, -1 here has a whole personality — it's -IGC_ERR_NVM, and that's the number you're getting back if the grant bit refuses to show up. 🫶
