=== NVMAP_IOC_CREATE ===
Creates an nvmap object. Identical to Linux driver.
  struct {
    u32 __size;  // in
    u32 __handle; // out
  };
=== NVMAP_IOC_FROM_ID ===
Get handle to an existing nvmap object. Identical to Linux driver.
  struct {
    u32 __id;    // in
    u32 __handle; // out
  };
=== NVMAP_IOC_ALLOC ===
Allocate memory for the nvmap object. Nintendo extended this one with 16 bytes, and changed it from in to inout.
  struct {
    u32 __handle;  // in
    u32 __heapmask; // in
    u32 __flags;    // in (0=read-only, 1=read-write)
    u32 __align;    // in
    u8  __kind;    // in
    u8  __pad[7];
    u64 __addr;    // in
  };
=== NVMAP_IOC_FREE ===
This one is completely custom. Partly because the Linux driver passed the handle as the ioctl "arg-ptr", and HIPC can't handle that voodoo.
  struct {
    u32 __handle;  // in
    u32 __pad;
    u64 __refcount; // out
    u32 __size;    // out
    u32 __flags;    // out, 1=NOT_FREED_YET
  };
=== NVMAP_IOC_PARAM ===
Returns info about a nvmap object. Identical to Linux driver, but extended with further params.
  struct {
    u32 __handle; // in
    u32 __param;  // in, 1=SIZE, 2=ALIGNMENT, 3=BASE (returns error), 4=HEAP (always 0x40000000), 5=KIND, 6=COMPR (unused)
    u32 __result; // out
  };
=== NVMAP_IOC_GET_ID ===
Returns an id for a nvmap object. Identical to Linux driver.
