			There are 4 KResourceLimit objects created on the kernel heap. Each is used for a different category specified by the exheader's resource limit category specifier in the exheader [[NCCH/Extended_Header#ARM11_Local_System_Capabilities\|ARM11 Local System Capabilities]].

			'''KPreemptionTimer''':

			A call to svcSetResourceLimitValues with a limit value of 1000 for CPU time must be done first to set up some global variables and the associated [[KTimeableInterruptEvent]] instances, and another call needs to be made to actually enable preemption.

	~~There are 4 KResourceLimit objects created~~ on the kernel ~~heap~~. ~~Each is used for a different category specified by the exheader's resource limit category specifier in the exheader [[NCCH~~/~~Extended_Header#ARM11_Local_System_Capabilities\|ARM11 Local System Capabilities]]~~.		Preemption type 0: this is the default, preempts threads on core1 and allow them to run only 2ms * (timeLimit / 100).

			Preemption type 1: ''seems'' to be borked, it was apparently intended to preempt threads on all cores but seems to only preempt the kernel thread running the preemptor itself and threads on core1... (time slice: 12.5ms * (timeLimit / 100))

			"Firm" dev consoles can switch between these two types using svcKernelSetState type 6.
