💅 fm10k_mbx_write_copy(9) — or, like, the Kernel API Manual page you didn't know you needed

okay bestie, buckle up, because this is a page out of the Kernel API Manual and honestly it's kind of a glow-up moment for the Tx FIFO 🎀

✨ NAME ✨

fm10k_mbx_write_copy — the function that pulls data off of the Tx FIFO and places it in mbmem 💖

🌸 SYNOPSIS 🌸

void fm10k_mbx_write_copy (struct fm10k_hw *hw , struct fm10k_mbx_info
*mbx );

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure 🖥️ like, the actual vibes of the silicon
  • mbx — pointer to the mailbox 📬 the whole main character of this function, no cap

💫 DESCRIPTION 💫

so the way this works ✨ — this function will take a section of the Tx FIFO and copy it straight into the mailbox memory. iconic behavior honestly.

the offset in mbmem is based on the lower bits of the tail 🎯 and len determines the length to copy. that's it, that's the whole lore 🦋

lowkey obsessed with how tidy that is — tail bits in, length says how much, data lands in mbmem. periodt 💅
