Yes, Linux only supports multiple messages with MSI-X, not MSI. This is an architectural limitation of "Intel-style" interrupt controllers (x86 and ia64). It is also a limitation of the Linux's MSI API, since there are platforms and devices for which an OS could allocate multiple MSI messages, but Linux has no interface that allows that. The historical reason for the Linux interface is simply that Intel platforms were the first place that MSI/MSI-X was supported. - R. - 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/
