I was going through the documentation of xen for device passthrough. From this, i understood that the dom0 doesn't have any control on passthrough of device. However, the modifications to be done to devicetree and the status of the device during initialization are unclear for me yet.
I am basically looking to passthrough the spi devices to domU.
Want to know more about the modifications to be done to device tree file and also to the domu config file.
