💅 parport_ip32_dma_start(9) 💅

okay bestie, welcome to parport_ip32_dma_start from the Kernel API Manual — yes, the manual name is literally in the house, and this function begins a DMA transfer. Slay.

🎀 NAME 🎀

parport_ip32_dma_start — begins a DMA transfer. That's the whole errand. Periodt.

✨ SYNOPSIS ✨

here's the signature, copied exactly, no edits, no vibes-based refactoring:

int parport_ip32_dma_start (struct parport *p , enum dma_data_direction
dir , void *addr , size_t count );

🌸 ARGUMENTS 🌸

Here's the cast of characters, bestie:

  • p — the partport to work on.
  • dir — DMA direction: DMA_TO_DEVICE or DMA_FROM_DEVICE.
  • addr — pointer to data buffer.
  • count — buffer size.

💖 DESCRIPTION 💖

Calls to parport_ip32_dma_start and parport_ip32_dma_stop must be correctly balanced.

That's the rule, no cap. Like, start goes with stop — keep them correctly balanced and don't leave a start just hanging there like an unread group-chat message 😭
