Hello everybody,
we are fairly new to XEN and have a few questions regarding our XEN
setup on Xilinx ZCU102 Board. We want to pass through the UART1 device
to a bare metal guest. The way Xilinx proposed in their documentation to
XEN BareMetal Guests is to add the following via an .dtsi file to the
device tree:
&&uart1 {
xen,passthrough = <0x1>;
};
Unfortunately, this does not work for us, we don't get any output on our
serial console.
We are using the config file which was provided by xilinx:
#Guest name
name = "hello_world"
# Kernel image to boot
kernel = "xapp_hello_world_el1.bin"
# Kernel command line options - Allocate 8MB
memory = 8
# Number of VCPUS
vcpus = 1
# Pin to CPU 0
cpus = [1]
irqs = [ 54 ]
iomem = [ "0xff010,1" ]
Maybe someone can give a few tips, which steps are necessary to pass a
device to a bare metal DOMU, or point out where we missed something.
Regards,
Jan
