SceLibKernel

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

Module

This is a user module and exists only in userland. 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	??

0x008	4	Stack start address
0x00C	4	Stack end address
0x010	4	Current VFP exception

0x020	4	Current priority
