hiii bestie 💖 welcome to the Kernel API Manual entry for ath5k_hw_dma_init(9) — short page, useful function, and we are keeping every single detail. no cap.

ath5k_hw_dma_init — Initialize DMA unit.

✨ SYNOPSIS ✨

void ath5k_hw_dma_init (struct ath5k_hw *ah );

💅 DESCRIPTION 💅

okay so the whole vibe here is: set DMA size and pre-enable interrupts. that's what this function does, periodt.

the parenthetical is important, bestie: driver handles tx/rx buffer setup and dma start/stop.

XXX: Save/restore RXDP/TXDP registers ?

the original leaves that one as a question, so we're leaving it as a question too 🫡.
