pm8001_mem_alloc(9)

💖 pm8001_mem_alloc(9) — the Kernel API Manual moment 💖

Okay so bestie, we're in the Kernel API Manual today and this page is literally called pm8001_mem_alloc(9) — say that three times fast, I dare you 🫶. It's a lil kernel-API page about grabbing memory for pm8001, and honestly? It's giving "small but mighty" ✨.

---

🌸 NAME 🌸

pm8001_mem_alloc — allocate memory for pm8001. That's it, that's the whole vibe 💅.

---

⭐ SYNOPSIS ⭐

int pm8001_mem_alloc (struct pci_dev *pdev , void **virt_addr ,
dma_addr_t *pphys_addr , u32 *pphys_addr_hi , u32 *pphys_addr_lo , u32
mem_size , u32 align );

Not me just pasting the whole signature exactly as it is 😭 — seven params, one int return, zero notes. Iconic.

🎀 ARGUMENTS 🎀

Okay so here's the whole cast, each one main-character in their own way 👑

• pdev — a pci device. Your lil PCI buddy 🦋.
• virt_addr — the allocated virtual address. Yes, the allocated one 💖.
• pphys_addr — the DMA address for this device. Don't lose it, bestie 🙈.
• pphys_addr_hi — the physical address high byte address. The high half 🔥.
• pphys_addr_lo — the physical address low byte address. The low half 🍓.
• mem_size — memory size. How much memory, exactly. Very on-the-nose, we stan ⭐.
• align — requested byte alignment. Byte alignment that is requested. Periodt 💅.

That's all seven, and yes, there's no description paragraph and no return-value section — the page is lowkey just vibes and signatures 🌈.
