GPIO emulation in QEMU RISCV

Hi Daniel,

We are working to generate device interrupts via GPIO.But the problem here is by default the QEMU doesn't have any GPIO device emulated. (QEMU 8.0.0)

1. How to emulate the VIRT GPIO device or any other GPIO device in QEMU? The device models listed in QEMU don't have any of the GPIO devices listed. Any idea how to enable any of the GPIO device emulation in QEMU RISCV?

2. Also whether a software patch is required for the QEMU to enable it? If so, please point to it.

Thanks,

SIva.S
