ARM big.LITTLE vs. nvidia Tegra 3 Kal-ElARM big.LITTLE vs. nvidia Tegra 3 Kal-ElPosted Feb 15, 2012 15:50 UTC (Wed) by Felix.Braun (subscriber, #3032)In reply to: Linux support for ARM big.LITTLE by SEJeff Parent article: Linux support for ARM big.LITTLE
However, as I understand it, in Tegra 3 doesn't expose all processors to the OS. Instead it makes the decisions in hardware, when to use the smaller processor (it's only one small processor in Kal-El's case IIRC) and when to switch on the big processors.
A software approach seems more flexible to me, which is a good thing considering the complexity of the issue. This seems impossible to get right in the first try.
