2014-08-05vfio: Fix MSI-X vector expansionAlex Williamson
When new MSI-X vectors are enabled we need to disable MSI-X and re-enable it with the correct number of vectors. That means we need to reprogram the eventfd triggers for each vector. Prior to f4d45d47 vector->use tracked whether a vector was masked or unmasked and we could always pick the KVM path when available for unmasked vectors. Now vfio doesn't track mask state itself and vector->use and virq remains configured even for masked vectors. Therefore we need to ask the MSI-X code whether a vector is masked in order to select the correct signaling path. As noted in the comment, MSI relies on hardware to handle masking.

2014-07-29pc: acpi: generate AML only for PCI0 devices if PCI bridge hotplug is disabledIgor Mammedov
Fixes migration regression from QEMU-1.7 to a newer QEMUs. SSDT table size in QEMU-1.7 doesn't change regardless of a number of PCI bridge devices present at startup. However in QEMU-2.0 since addition of hotplug on PCI bridges, each PCI bridge adds ~1875 bytes to SSDT table, including pc-i440fx-1.7 machine type where PCI bridge hotplug disabled via compat property. It breaks migration from "QEMU-1.7" to "QEMU-2.[01] -M pc-i440fx-1.7" since RAMBlock size of ACPI tables on target becomes larger then on source and migration fails with: "Length mismatch: /rom@etc/acpi/tables: 2000 in != 3000" error. Fix this by generating AML only for PCI0 bus if hotplug on PCI bridges is disabled and preserves PCI brigde description in AML as it was done in QEMU-1.7 for pc-i440fx-1.7. It will help to maintain size of SSDT static regardless of number of PCI bridges on startup for pc-i440fx-1.7 machine type.

2014-07-28pc: hack for migration compatibility from QEMU 2.0Paolo Bonzini
Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

2014-07-28acpi-dsdt: procedurally generate _PRTPaolo Bonzini
This replaces the _PRT constant with a method that computes it. The problem is that the DSDT+SSDT have grown from 2.0 to 2.1, enough to cross the 8k barrier (we align the ACPI tables to 4k before putting them in fw_cfg). This causes problems with migration and the pc-i440fx-2.0 machine type. The solution to the problem is to hardcode 64k as the limit, but this doesn't solve the bug with pc-i440fx-2.0. The fix will be for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the ACPI tables. First, however, we must make the actual AML equal or smaller; to do this, rewrite _PRT in a way that saves over 1k of bytecode.
