- Thread-topic: XEN ARM dt passthrough
Hi,
I'm trying to follow this guide to passthrough a device tree device.
https://xenbits.xen.org/docs/unstable/misc/arm/passthrough.txt
The device doesn't have an IOMMU thus I've enabled
xen,force-assign-without-iommu
In the guest dts but when I create the VM I get the following message.
user@imx8mpnavq:~/guest$ sudo xl create domU_test
Parsing config from domU_test
libxl: error: libxl_create.c:1135:libxl__domain_config_setdefault: passthrough
not supported on this platform
failed to free memory for the domain
How do I enable the support for passthrough for my ARM based platform?
Yours sincerely,
Peter van der Perk
