[[Configuration_Memory|0x1FF80015]] ("is devmode enabled") needs to be true.
If this is 0 (Prod) or any invalid value, nothing is done. If it is 1 (Dev), <code>unk != 0</code> is written to some global variable; if this variable has bit0 clear, the regdump will be written when an exception occurs in a privileged mode (the destination depends on fields in the local storage of the current thread at the time of the exception).
If <code>what</code> is 0 or any invalid value, nothing is done.
If 2 (Debugger), it's written to the following byte.
If it is 1, <code>val != 0</code> is written to the global variable enabling register dumps on CPU exceptions (dumps that are fetched with svcGetDebugThre44adContext)
If 3 (Firm), this calls a scheduler-related function with <code>(u32)unk</code> which performs a context switch, and that value to a global variable if its contents are not equal to the arg, under certain conditions (returns error 0xC8A01414 otherwise).
If 2, kernelpanic will be called when svcBreak is used by a non-attached process
If 3, this changes the scheduling/preemption mode (when no threads are being preempted, otherwise returns error 0xC8A01414), see [[KResourceLimit]] for more details.
