Anyway, is it a valid (virtualized) hardware? Is ARMv8 timer really, really compatible with ARMv7 one? I don't think we should document invalid setups out-of-tree, just because they are there, and something like this was also expressed by Rob: https://lore.kernel.org/all/20220518163255.GE3302100-robh@xxxxxxxxxx/ Best regards, Krzysztof
