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.

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