SceSysmem

SceSysmem is a kernel module that acts as the heart of the kernel. It exports multiple libraries for various features. SceSysmem is the first module that is loaded in the kernel load sequence and its libraries are imported by almost all other modules. See Virtual Memory and Physical Memory for more details on the memory subsystem.

Module
This module exists in both non-secure and secure world. The non-secure world SELF can be found in. It also can be found in the Boot Image.

Memory Block Type
The  parameter indicates what kind of memory to allocate. Here is a mapping of  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.
