SceLibKernel, not to be confused with Kernel is a user module that implements wrappers to some common syscalls (for example, SceIofilemgr), some usermode standard library functions (including C standard library), and other common features like heap management. This module is the functionality similar to libc.so.6 on Linux.

Module

This is a usermode module and exists only in usermode. The SELF can be found in os0:us/libkernel.suprx.

Heap

The latest version of dlmalloc is included in SceLibKernel. Most of the assert checks and security are included.

Thread specific data

Each thread owns a private 2048bytes memory region with specific data (?TLS?). The end of this region is pointed by the TPIDRURO register (thus, the start address of it is TPIDRURO - 0x800).

Offset Size Description
0x000 4 ??
0x004 4 Thread ID
0x008 4 Stack start address
0x00C 4 Stack end address
0x010 4 Current VFP exception
0x014 4 LwMutex related
0x020 4 Current priority
0x024 4 CPU affinity mask
