How to make the interrupt function working on Windows 10?

Hi,
I'm developing Windows 10 device driver on UP2 board. My driver needs the interrupt function to report data to Windows. I set pin16 of HAT40 (GPIO19) as the interrupt pin in BIOS and ASL code:
GpioInt(Level, ActiveLow, Exclusive, PullNone, 0, "\\_SB.GPO0", ) {0x13}
But my driver never receives interrupt with this configuration. Besides, I found no GPIO controller is shown in System devices of Device Manager. Could you please advise how to make the interrupt function working on Windows 10?

After further checking DSDT table, I found why GPIO controller is not shown in Device Manager - the _STA method returns 0x0B.
Any reason for doing so?Device (GPO0) { Name (_ADR, Zero) // _ADR: Address Name (_HID, "INT3452") // _HID: Hardware ID Name (_CID, "INT3452") // _CID: Compatible ID Name (_DDN, "General Purpose Input/Output (GPIO) Controller - North") // _DDN: DOS Device Name Name (_UID, One) // _UID: Unique ID Name (LINK, "\\_SB.GPO0") Name (RBUF, ResourceTemplate () { Memory32Fixed (ReadWrite, 0x00000000, // Address Base 0x00004000, // Address Length _Y07) Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, ) { 0x0000000E, } }) Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { CreateDWordField (RBUF, \_SB.GPO0._Y07._BAS, B0BA) // _BAS: Base Address CreateDWordField (RBUF, \_SB.GPO0._Y07._LEN, B0LN) // _LEN: Length B0BA = GP0A /* \GP0A */ B0LN = GP0L /* \GP0L */ Return (RBUF) /* \_SB_.GPO0.RBUF */ } Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0B) } :
