mpi3mr_allo...l_dma_memory(9)

✨ NAME ✨

okay so bestie, this is the Kernel API Manual page for mpi3mr_alloc_ioctl_dma_memory(9), and it is literally here to Alloc memory for ioctl dma. that's the whole name, no cap 💅

🛠️ SYNOPSIS 🛠️

void mpi3mr_alloc_ioctl_dma_memory (struct mpi3mr_ioc *mrioc );

that's the signature exactly as it appears — no extra args, no secret handshake 🫶

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. it's the adapter instance reference you hand over so the function knows which adapter we're talking about 💖

💖 DESCRIPTION 💖

bestie, this function allocates dmaable memory — yes, that's the exact spelling — required to handle the application issued MPI3 IOCTL requests. it's giving “get the memory ready so those app IOCTL requests can be handled” energy, periodt ✨

🌈 RETURN 🌈

None. zero. nada. it does not return a value — literally None 💀
