Okay bestie, welcome to i40e_nvmupd_state_reading(9) from the Kernel API Manual — this is the function that deals with the Reading state while an NVM update is happening. 🫶

✨ SYNOPSIS ✨

int i40e_nvmupd_state_reading (struct i40e_hw *hw , struct
       i40e_nvm_access *cmd , u8 *bytes , int *perrno );

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. literally the hardware bestie 💅
• cmd — pointer to nvm update command buffer. the command vibes live here ✨
• bytes — pointer to the data buffer. data goes brrr 🌸
• perrno — pointer to return error code. this is where the error code gets reported 🎀

🦋 DESCRIPTION 🦋

NVM ownership is already held here — yes, it’s already ours at this point, no cap. The function processes legitimate commands and sets any change in state; all other commands get rejected. Periodt. 💅
