Hi Avi & Marcelo This patchset would add emulation of MSI-X mask bit for assigned devices in QEmu. BTW: We are also purposed an acceleration of MSI-X mask bit for KVM - to get it done in kernel. That's because sometime MSI-X mask bit was accessed very frequently by guest and emulation in QEmu cost a lot(tens to hundreds percent CPU utilization sometime), e.g. guest using Linux 2.6.18 or under some heavy workload. The method has been proved efficient in Xen, but it would require VMM to handle MSI-X table. Is that OK with you? -- regards Yang, Sheng -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
