Here we go with take 4. Changes: - Check the requested number of interrupts against the maximum number the device claims to support. Thanks to Hidetoshi Seto for pointing out this oversight. - Implemented Eric's suggestion of using a single IRQ and storing the data with it. - As a result, don't try to support the mode in the AHCI driver where the excess ports all share the last interrupt. It could be done, but it would be rather messy and I don't have hardware that supports that mode anyway. I'm fairly comfortable with the subchannel notion we're introducing here. It's more flexible than MSI and doesn't impose a penalty on architectures which don't implement it. It makes some things more complex, but it makes other things simpler, so I think it's a wash from a cleanliness standpoint. Git tree still at git://git.kernel.org/pub/scm/linux/kernel/git/willy/misc.git multiple-msi (and this push specifically at multiple-msi-20080711) Patches to follow. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
