xdma_alloc_channels(9)

✨ NAME ✨

okay so listen, bestie — we're flipping through the Kernel API Manual and this page is xdma_alloc_channels(9). Its whole thing is literally detect and allocate DMA channels. that's the assignment, and it ate. 💅✨

🦋 SYNOPSIS 🦋

vibe check: the signature is giving main-character energy, no cap:

int xdma_alloc_channels (struct xdma_device *xdev , enum
       dma_transfer_direction dir );

💅 ARGUMENTS 💅

• xdev — DMA device pointer.
• dir — Channel direction.

two arguments, zero drama. periodt. 🫶
