2013-01-11hw/pc.c: Fix converting of ioport_register* to MemoryRegionJulien Grall
The commit 258711 introduced MemoryRegion to replace ioport_region* for ioport 80h and F0h. A MemoryRegion needs to have both read and write callback otherwise a segfault will occur when an access is made. The previous behaviour of this both ioport is to return 0xffffffffffffffff. So keep this behaviour.

Starting with release 1.4 we have a fully functional q35 machine type, i.e. "qemu -M q35" JustWorks[tm]. Update machine type names to reflect that: * pc-1.4 becomes pc-i440fx-1.4 * q35-next becomes pc-q35-1.4 The pc-1.3 (+older) names are maintained for compatibility reasons. For the same reason the "pc" and "q35" aliases are kept. pc-piix-1.4 continues to be the default machine type, again for compatibility reasons.

Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-09Check return values from g_poll and selectFabien Chouteau
The current implementation of os_host_main_loop_wait() on Windows, returns 1 only when a g_poll() event occurs because the return value of select() is overridden. This is wrong as we may skip a socket event, as shown in this example: 1. select() returns 0 2. g_poll() returns 1 (socket event occurs) 3. os_host_main_loop_wait() returns 1 4. qemu_iohandler_poll() sees no socket event because select() has return before the event occurs 5. select() returns 1 6. g_poll() returns 0 (g_poll overrides select's return value) 7. os_host_main_loop_wait() returns 0 8. qemu_iohandler_poll() doesn't check for socket events because the return value of os_host_main_loop_wait() is zero. 9. goto 5 This patch use one variable for each of these return values, so we don't miss a select() event anymore. Also move the call to select() after g_poll(), this will improve latency as we don't have to go through two os_host_main_loop_wait() calls to detect a socket event.

2013-01-09pci-assign: Enable MSIX on device to match guestAlex Williamson
When a guest enables MSIX on a device we evaluate the MSIX vector table, typically find no unmasked vectors and don't switch the device to MSIX mode. This generally works fine and the device will be switched once the guest enables and therefore unmasks a vector. Unfortunately some drivers enable MSIX, then use interfaces to send commands between VF & PF or PF & firmware that act based on the host state of the device. These therefore may break when MSIX is managed lazily. This change re-enables the previous test used to enable MSIX (see qemu-kvm a6b402c9), which basically guesses whether a vector will be used based on the data field of the vector table.

2013-01-08qemu-ga: execute hook to quiesce the guest on fsfreeze-freeze/thawTomoki Sekiyama
To use the online disk snapshot for online-backup, application-level consistency of the snapshot image is required. However, currently the guest agent can provide only filesystem-level consistency, and the snapshot may contain dirty data, for example, incomplete transactions. This patch provides the opportunity to quiesce applications before snapshot is taken. If --fsfreeze-hook option is specified, the hook is executed with "freeze" argument before the filesystem is frozen by fsfreeze-freeze command. As for fsfreeze-thaw command, the hook is executed with "thaw" argument after the filesystem is thawed.

2013-01-08vfio-pci: Make host MSI-X enable track guestAlex Williamson
Guests typically enable MSI-X with all of the vectors in the MSI-X vector table masked. Only when the vector is enabled does the vector get unmasked, resulting in a vector_use callback. These two points, enable and unmask, correspond to pci_enable_msix() and request_irq() for Linux guests. Some drivers rely on VF/PF or PF/fw communication channels that expect the physical state of the device to match the guest visible state of the device. They don't appreciate lazily enabling MSI-X on the physical device. To solve this, enable MSI-X with a single vector when the MSI-X capability is enabled and immediate disable the vector. This leaves the physical device in exactly the same state between host and guest. Furthermore, the brief gap where we enable vector 0, it fires into userspace, not KVM, so the guest doesn't get spurious interrupts. Ideally we could call VFIO_DEVICE_SET_IRQS with the right parameters to enable MSI-X with zero vectors, but this will currently return an error as the Linux MSI-X interfaces do not allow it.

2013-01-08target-i386: check/enforce: Check SVM flag support as wellEduardo Habkost
When nested SVM is supported, the kernel returns the SVM flag on GET_SUPPORTED_CPUID[1], so we can check the SVM flag safely in kvm_check_features_against_host(). I don't know why the original code ignored the SVM flag. Maybe it was because kvm_cpu_fill_host() used the CPUID instruction directly instead of GET_SUPPORTED_CPUID [1] Older kernels (before v2.6.37) returned the SVM flag even if nested SVM was _not_ supported. So the only cases where this patch should change behavior is when SVM is being requested by the user or the CPU model, but not supported by the host. And on these cases we really want QEMU to abort if the "enforce" option is set.

I believe it was a mistake, and it was supposed to be ~(PPRO_FEATURES & CPUID_EXT2_AMD_ALIASES) or just ~CPUID_EXT2_AMD_ALIASES, because some time ago kvm_cpu_fill_host() used the CPUID instruction directly (instead of kvm_arch_get_supported_cpuid()). But now kvm_cpu_fill_host() uses kvm_arch_get_supported_cpuid(), and kvm_arch_get_supported_cpuid() returns all supported bits for CPUID.80000001H.EDX, even the AMD aliases (that are explicitly copied from CPUID.01H.EDX), so we can make the code check/enforce all the CPUID.80000001H.EDX bits.

2013-01-08target-i386: check/enforce: Fix CPUID leaf numbers on error messagesEduardo Habkost
The -cpu check/enforce warnings are printing incorrect information about the missing flags. There are no feature flags on CPUID leaves 0 and 0x80000000, but there were references to 0 and 0x80000000 in the table at kvm_check_features_against_host(). This changes the model_features_t struct to contain the register number as well, so the error messages print the correct CPUID leaf+register information, instead of wrong CPUID leaf numbers. This also changes the format of the error messages, so they follow the "CPUID.<leaf>.<register>.<name> [bit <offset>]" convention used in Intel documentation.

2013-01-08target-i386: kvm: Enable all supported KVM features for -cpu hostEduardo Habkost
When using -cpu host, we don't need to use the kvm_default_features variable, as the user is explicitly asking QEMU to enable all feature supported by the host. This changes the kvm_cpu_fill_host() code to use GET_SUPPORTED_CPUID to initialize the kvm_features field, so we get all host KVM features enabled. This will also allow us to properly check/enforce KVM features inside kvm_check_features_against_host() later. For example, we will be able to make this: $ qemu-system-x86_64 -cpu ...,+kvm_pv_eoi,enforce refuse to start if kvm_pv_eoi is not supported by the host (after we fix kvm_check_features_against_host() to check KVM flags as well).
