Once blacklisting has been improved/completed, we can enable MSI by default (and keep "pci=nomsi" in case a non-blacklisted chipset appears). Or we could enable MSI by default on PCI-E chipsets and disable by default on non-PCI-E (ie we whitelist non-PCI-E only) ? PCI-E chipsets seem to support MSI pretty well. I am ok with any strategy as long as I don't end up passing "pci=nomsi" on most new machines I will install in the next 10 years (as I did with "noapic" in the past) :) Brice - 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/ | ||||||||||
