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 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.

0xFF00	0x4000	`TEX[2]` and `B` bit set. Outer cache non-cachable. Inner cache Write-back, Write-Allocate
0xFF00	0x8000	`TEX[0]` bit set. `S` bit unset. Outer and inner non-cachable. Not sharable.
0xFF00	0xD000	`TEX[0]` bit set. `C,B` bits set. Outer and inner Write-back, Write-Allocate.
0xFF	0x4	`AP[2:0] = 5`, `XN=1`. Privileged RO, User NA.
