💅 rproc_alloc_carveout(9) 💅

okay so bestie, literally welcome to the Kernel API Manual — yes, the actual Kernel API Manual, we're doing this 💖 this page is all about rproc_alloc_carveout, and it's lowkey one of those tiny functions that just does the thing so let's get into it.

✨ NAME ✨

rproc_alloc_carveout — allocates the specified carveout 🎀

🦋 SYNOPSIS 🦋

int rproc_alloc_carveout (struct rproc *rproc , struct rproc_mem_entry
*mem );

🌸 ARGUMENTS 🌸

  • rproc — the rproc handle, aka your main character struct pointer, the whole reason we're here 🫶
  • mem — the memory entry to allocate, the actual thing we're carving out, slay

💫 DESCRIPTION 💫

So this function allocates the specified memory entry mem, and it uses dma_alloc_coherent as the default allocator — no cap, that's the default allocator, it's giving "I got you, bestie" energy ✨

👑 RETURN 👑

  • 0 on success 🎉
  • or an appropriate error code otherwise 😭 (so like, vibe check your return value, fr fr)

🌈 SEE ALSO 🌈

okay this list is iconic, it's literally the whole remoteproc friend group, all of them, we are not skipping a single one 💅

and that's the whole page bestie, go carve out your memory entry, you're gonna do amazing 💜🧚‍♀️

so like, the source lives in ./drivers/remoteproc and the version/date stamp on this one is October 2026, and the manual it belongs to is the Kernel API Manual — mwah, that's the sign-off, bye bestie 🎀💖✨
