okay so bestie, this is the Kernel API Manual page for e1000_write_posted_mbx(9), and it’s lowkey giving “send the message, then wait for the ack” main character energy. Let’s get into it 💅

🌸 NAME 🌸

e1000_write_posted_mbx — write a message to the mailbox, wait for ack. That’s the assignment, periodt.

✨ SYNOPSIS ✨

s32 e1000_write_posted_mbx (struct e1000_hw *hw , u32 *msg , u16 size );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. the hardware bestie in question 🫶
• msg — The message buffer. where the message lives 🦋
• size — Length of buffer. the size, obviously 💅

💅 DESCRIPTION 💅

This one returns SUCCESS if it successfully copied message into the buffer and received an ack to that message within delay * timeout period. That’s the success condition, no cap. The ack has to land inside that delay * timeout period, and that’s the whole vibe check here. ✨
