dmaengine_terminate_sync(9)

💅 dmaengine_terminate_sync(9) 💅

okay so bestie, this is the dmaengine_terminate_sync(9) page from the Kernel API Manual ✨ and it’s giving “are we actually done? fr fr?” energy for DMA termination. no cap.

🌸 NAME 🌸

dmaengine_terminate_sync — Terminate all active DMA transfers

✨ SYNOPSIS ✨

int dmaengine_terminate_sync (struct dma_chan *chan );

🎀 ARGUMENTS 🎀

• chan — The channel for which to terminate the transfers.

🦋 DESCRIPTION 🦋

Calling this function will terminate all active and pending transfers that have previously been submitted to the channel. It is similar to dmaengine_terminate_async, but it guarantees that the DMA transfer has actually stopped and that all complete callbacks have finished running when the function returns. like, actually finished-finished 💅

⚠️ This function must only be called from non-atomic context and must not be called from within a complete callback of a descriptor submitted on the same channel.
