I haven't investigated yet, but on my Lenovo ULT Haswell laptop the IMC PCI-ID doesn't exist, so the driver doesn't initialize. So either it's the BIOS disabling it, or it's a different ID there too. BTW any reason you didn't enable the CBOX/ARB PMUs originally for HSW? At least ARB events are useful for some things. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
