AppleEmbeddedNVMeController

AppleEmbeddedNVMeController is a kernel extension for managing the NAND (disk) of via Peripheral Component Interconnect Express (PCIe) bus.

Methods

Selector	Action	Input	Output
2	sendNVMECommand	struct NVMeCommand*	__n128 unknown
3	isBFHMode	-	bool bfhMode
4	performBFH	-	-
5	getNANDDescriptor	-	-
6	setNVMeState	-	-
7	setPCIPortState	-	-
8	setBFHGPIO	uint64_t value	uint64_t unknown

NOTE: this table currently is only showing the selectors, the input / output will be documented later.
