Hello all, I am facing the (long term) issue of having to detect the GIC version in the host and in the kvm guest (OSv); at the moment we minimally support GICv2 in the guest, but I'd like to make the code a bit better by detecting the GIC version in the guest, and in the future optionally adapt the functionality to what is available (GICv2, GICv2m, GICv3, ...) I know that the information could be taken from the device tree, and this is what I am going for in the short term, but eventually we need to be able to discover this without preconfigured information (thus being able to use the same images on multiple systems without having to provide additional external information). Is this something that can be read from the GIC registers (preferrably), or from ACPI? Thank you for any idea, Claudio _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
