Re: [gem5-dev] KVM broken on x86 due to changeset 1bd64b294fe4
Thanks! I should have checked the upstream commit log. //Andreas On 26/11/14 13:54, Gabe Black via gem5-dev wrote: I already fixed it. The change should be checked in, I think.

I already fixed it. The change should be checked in, I think. Gabe On Nov 26, 2014 5:52 AM, "Andreas Sandberg via gem5-dev" wrote: > I just ran into some issues with kvm on x86.

[gem5-dev] KVM broken on x86 due to changeset 1bd64b294fe4
I just ran into some issues with kvm on x86. It seems like changeset 1bd64b294fe4 (x86: add LongModeAddressSize function to cpuid) breaks Linux running in kvm. It seems like the offending change makes cpuid report the virtual and physical address length as 255 bits, which clearly doesn't make sense. I can't justify spending any time on it, so could someone else have a quick look? I'd suggest just reverting the patch for now unless someone else has a better suggestion. //Andreas -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
