Next version, now without RFC. The goals are still the same: - Being able to disable PCI support in a build completely. - Properly fencing off PCI if the relevant facility bit is not provided.
Changes v2->v3: - Only enable the zpci bit conditionally, keep the aen bit always on. Use a method that actually works... - Some reordering in the msi route patch to keep the change small. - Collected some r-bs. Branch is still git://github.com/cohuck/qemu no-zpci-cpumodel Likely 2.11 material, even though the 'fence off if facility bit is not set' part could count as bugfixes. Thoughts?
