I would assert that, at least in the case of the P4, there IS a "major core", as the 2 subcores share L1 and bus controller access, as well as several other parts of the chip. I beleive this is to some extent the case in the Power4 modules - that each module contains resources shared by the execution units. However, I might be full of it, and since there are plenty of @ibm.com's here I expect to be corrected shortly.... - 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/
