SceKernelThreadMgr

Vita supports multi-threading in the non-secure kernel but not the secure kernel. There is no user/POSIX threads; all threads are implemented as kernel threads and processes are the functionally the same as threads. Threads can be specified to run on a specific core with the CPU affinity mask option when creating the thread and by default, threads can run on any core. The kernel process can also run on any core. Additionally, the secure kernel can also run on any core.
