Memory Block Type

The type parameter indicates what kind of memory to allocate. Here is a mapping of type flags to ARM MMU flags. Higher bits are used for other options including where to allocate from. Not all flag values are valid, there is a table of valid types in the kernel. You cannot, for example, allocate RWX memory.

Note

The only commonly available memtypes are those that are publicly available.

sceKernelAllocMemblockInternal uses a list to translate it into an internal memtype.

So we can't create memtype with any bits and use that's.
