Hi! I've recently tried to boot clang built kernel on real hardware (Odroid C2 board) instead of using a VM. The issue that I stumbled upon is that arm64 kvm built with clang doesn't boot. Adding -fno-jump-tables compiler flag to arch/arm64/kvm/* helps. There was a patch some time ago that did exactly that (https://patchwork.kernel.org/patch/10060381/), but it wasn't accepted AFAICT (see the discussion on that thread). What would be the best way to get this fixed? I've also had to disable CONFIG_JUMP_LABEL to get the kernel boot (even without kvm enabled), but that might be a different (though related) issue. Thanks! _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
