unsigned int pspSdkSetK1

(

unsigned int

k1

)

Set the processors K1 register to a known value.

Note:

This function is for use in kernel mode syscall exports. The kernel sets the k1 register to indicate what mode called the function, i.e. whether it was directly called, was called via a syscall from a kernel thread or called via a syscall from a user thread. By setting k1 to 0 before doing anything in your code you can make the other functions think you are calling from a kernel thread and therefore disable numerous protections.

Parameters:

k1

- The k1 value to set

Returns:

The previous value of k1
