okay so picture this: you're in the kernel API manual, section 9, and there's this lil function called ax_spi_fill_tx_fifo and honestly? it's giving "load the truck until the truck is full." that's the whole vibe. she fills the TX FIFO with as many bytes as possible, no cap, and then she's done. periodt.

🎀 NAME 🎀

ax_spi_fill_tx_fifo — fills the TX FIFO with as many bytes as possible 💖

like… as many as possible. she's not stopping early, she's not doing half the job, she's going until the FIFO says "girl i'm full." iconic behavior fr fr.

✨ SYNOPSIS ✨

void ax_spi_fill_tx_fifo (struct ax_spi *xspi );

that's it. that's the whole call. no return value, no drama, no exit status — she returns void because she's got nothing to prove 🫶
