SceSysmem: Difference between revisions

Revision as of 23:35, 5 June 2021

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 os0:kd/sysmem.skprx. It also can be found in the Boot Image.

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.

Permission is either "1" for read only, no execute or "2"/"3" for read write, no execute. Type is either 0, 1, or 17 and affects the block type. 0 is default. This will allocate kernel memory starting at kernel_page. To get the same memory as the user pointer, add the kernel_offset. kernel_size is how much is allocated.
