That would be essentially linux supported undervolting which for stability is as bad as overclocking. The problem is that such games tend to generate weird kernel crashes and then chew up development issues when kernel hackers have to chase ghost bugs. I don't think we should support it. Developer time is too precious. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
