okay so you're reading the Kernel API Manual bestie, and this is the page for ep93xx_dma_advance_work β yes it's a whole mouthful, yes it's iconic π
πΈ NAME πΈ
ep93xx_dma_advance_work β start processing the next pending transaction
likeβ¦ literally, it kicks off the next thing in the queue π
π¦ SYNOPSIS π¦
void ep93xx_dma_advance_work (struct ep93xx_dma_chan *edmac );
no cap, that's the whole signature β it returns void, so don't go looking for a return value, there isn't one π«Ά
π ARGUMENTS π
edmacβ the channel π (that's it, that's the vibe β it's thestruct ep93xx_dma_chan *you're working on)
β DESCRIPTION β
so here's the tea β β if we have pending transactions queued up, and we're currently idling, then this function does its little main-character moment: it takes the next queued transaction from edmac->queue and pushes it to the hardware for execution π₯
that's the entire job. queued + idling = grab the next one and hand it off to the hardware. slay β¨
