Re: Vfio-on-arm: the device tree does not contain the DMA device

[Shannon Zhao <zhaoshenglong-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>]

Hi Bharat,

Thanks for your help.

I executed the following cmd:
	echo vfio-platform > /sys/bus/platform/devices/2c0a0000.dma/driver_override
But there is no /dev/vfio/0 and error reported starting guest

	-nographic can not be used with -daemonize
	char device redirected to /dev/pts/3 (label pty0-base)
	PL330_VFIO: Group is not viable (not all devices bound for vfio)
	qemu-system-arm: Error while probing real device.

	qemu-system-arm: Initialization of device pl330 failed
Is there something wrong?

Thank you very much.
Shannon
