💖 vme_alloc_consistent(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the page for vme_alloc_consistent, and honestly? she's a little function with one job and she does it. slay.

✨ NAME ✨

vme_alloc_consistent — allocate contiguous memory. that's it. that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

void * vme_alloc_consistent (struct vme_resource *resource , size_t size
, dma_addr_t *dma );

like, yes, that's the whole signature. three args, one pointer back. iconic.

🌸 ARGUMENTS 🌸

  • resource — pointer to a VME resource. you know, the thing you already got from somewhere. 🫶
  • size — the size of the allocation you need. how much memory. the amount. the quantity. 💅
  • dma — pointer to a variable where the physical address of the allocation gets stored. she writes it for you, you're welcome. ✨

💜 DESCRIPTION 💜

okay so what she actually does: she allocates a contiguous block of memory for use by the driver. block is contiguous. that matters. contiguous. no cap. 🔥

and why do you care? because this is the function used to create the buffers for the slave windows. that's the whole reason she exists. slave window buffers. periodt. 👑

⭐ RETURN ⭐

  • virtual address of the allocation on success 💖
  • NULL on failure 😭
literally just check for NULL, bestie. it's giving "simple error handling" and we love that for us.
