💅 fm10k_mbx_enqueue_tx(9) — the Kernel API Manual page your group chat has been waiting for 🎀

okay so bestie, welcome to the Kernel API Manual, entry fm10k_mbx_enqueue_tx(9). this is the one that slides your message into the back of the Tx FIFO like it's getting in the club line. let's go ✨

🌸 NAME 🌸

fm10k_mbx_enqueue_tx — literally enqueues the message to the tail of the Tx FIFO. that's it, that's the whole vibe. 💫

⭐ SYNOPSIS ⭐

s32 fm10k_mbx_enqueue_tx (struct fm10k_hw *hw , struct fm10k_mbx_info
*mbx , const u32 *msg );

three args, one s32 back, no cap. 🫶

🦋 ARGUMENTS 🦋

  • hw — pointer to hardware structure. this is your hardware bestie, the source of truth. iconic.
  • mbx — pointer to mailbox. yes, the actual mailbox, the whole point of the function, main character energy fr fr.
  • msg — message array to read. the goods. the payload. 💌

💖 DESCRIPTION 💖

so what does it DO? it enqueues a message — up to the size specified by the length contained in the first DWORD of the message — and places it at the tail of the FIFO. read that again: the length lives in the first DWORD, so the size isn't a separate argument, it's baked into the message itself. iykyk. 🔥

it will return 0 on success, or a negative value on error. so no ambiguity, no mystery: 0 = we ate, negative = something went sideways 😭
