I'm confused now, because I thought the whole point of this patch was that we don't support guests on big.LITTLE but we're not locking them out (the way we would for an all-A7 system). That is, we're fixing a bug in the check code. Obviously it seems worth investigating exactly what is happening on the A7s when we try to run the init code, but it seems to me like that's the orthogonal issue, because we shouldn't be running that code in the first place. -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
