2013-01-08qemu-ga: execute hook to quiesce the guest on fsfreeze-freeze/thawTomoki Sekiyama3-1/+117
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.

VFIO_PCI_NUM_REGIONS and VFIO_PCI_NUM_IRQS should never have been used in this manner as it locks a specific kernel implementation. Future features may introduce new regions or interrupt entries (VGA may add legacy ranges, AER might add an IRQ for error signalling). Fix this before it gets us into trouble.

2013-01-08vfio-pci: Make host MSI-X enable track guestAlex Williamson1-4/+26
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 Habkost1-1/+1
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 have no idea why PPRO_FEATURES was being ignored on the check of the CPUID.80000001H.EDX bits. 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 Habkost2-9/+36
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. Example output: $ qemu-system-x86_64 -machine pc-1.0,accel=kvm -cpu Opteron_G4,+ia64,enforce warning: host doesn't support requested feature: CPUID.01H:EDX.ia64 [bit 30] warning: host doesn't support requested feature: CPUID.01H:ECX.xsave [bit 26] warning: host doesn't support requested feature: CPUID.01H:ECX.avx [bit 28] warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6] warning: host doesn't support requested feature: CPUID.80000001H:ECX.misalignsse [bit 7] warning: host doesn't support requested feature: CPUID.80000001H:ECX.3dnowprefetch [bit 8] warning: host doesn't support requested feature: CPUID.80000001H:ECX.xop [bit 11] warning: host doesn't support requested feature: CPUID.80000001H:ECX.fma4 [bit 16] Unable to find x86 CPU definition $ Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-08target-i386: kvm: Enable all supported KVM features for -cpu hostEduardo Habkost1-0/+2
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).

2013-01-08target-i386: kvm: -cpu host: Use GET_SUPPORTED_CPUID for SVM featuresEduardo Habkost1-7/+4
The existing -cpu host code simply sets every bit inside svm_features (initializing it to -1), and that makes it impossible to make the enforce/check options work properly when the user asks for SVM features explicitly in the command-line. So, instead of initializing svm_features to -1, use GET_SUPPORTED_CPUID to fill only the bits that are supported by the host (just like we do for all other CPUID feature words inside kvm_cpu_fill_host()). This will keep the existing behavior (as filter_features_for_kvm() already uses GET_SUPPORTED_CPUID to filter svm_features), but will allow us to properly check for KVM features inside kvm_check_features_against_host() later. For example, we will be able to make this: $ qemu-system-x86_64 -cpu ...,+pfthreshold,enforce refuse to start if the SVM "pfthreshold" feature is not supported by the host (after we fix kvm_check_features_against_host() to check SVM flags as well).

2013-01-08qdev: Don't assume existence of parent bus on unparentingAndreas Färber1-3/+5
Commit 667d22d1ae59da46b4c1fbd094ca61145f19b8c3 (qdev: move bus removal to object_unparent) made the assumption that at unparenting time parent_bus is not NULL. This assumption is unjustified since object_unparent() may well be called directly after object_initialize(), without any qdev_set_parent_bus(). This did not cause any issues yet because qdev_[try_]create() does call qdev_set_parent_bus(), falling back to SysBus if unsupplied. While at it, ensure that this new function uses the device_ prefix and make the name more neutral in light of this semantic change.

2013-01-08usbredir: Add support for buffered bulk input (v2)Hans de Goede8-21/+2718
Buffered bulk mode is intended for bulk *input* endpoints, where the data is of a streaming nature (not part of a command-response protocol). These endpoints' input buffer may overflow if data is not read quickly enough. So in buffered bulk mode the usb-host takes care of the submitting and re-submitting of bulk transfers. Buffered bulk mode is necessary for reliable operation with the bulk in endpoints of usb to serial convertors. Unfortunatelty buffered bulk input mode will only work with certain devices, therefor this patch also adds a usb-id table to enable it for devices which need it, while leaving the bulk ep handling for other devices unmodified. Note that the bumping of the required usbredir from 0.5.3 to 0.6 does not mean that we will now need a newer usbredir release then qemu-1.3, .pc files reporting 0.5.3 have only ever existed in usbredir builds directly from git, so qemu-1.3 needs the 0.6 release too.

2013-01-07target-ppc: Slim conversion of model definitions to QOM subclassesAndreas Färber7-176/+276
Since the model list is highly macrofied, keep ppc_def_t for now and save a pointer to it in PowerPCCPUClass. This results in a flat list of subclasses including aliases, to be refined later. Move cpu_ppc_init() to translate_init.c and drop helper.c. Long-term the idea is to turn translate_init.c into a standalone cpu.c. Inline cpu_ppc_usable() into type registration. Split cpu_ppc_register() in two by code movement into the initfn and by turning the remaining part into a realizefn. Move qemu_init_vcpu() call into the new realizefn and adapt create_ppc_opcodes() to return an Error. Change ppc_find_by_pvr() -> ppc_cpu_class_by_pvr(). Change ppc_find_by_name() -> ppc_cpu_class_by_name(). Turn -cpu host into its own subclass. This requires to move the kvm_enabled() check in ppc_cpu_class_by_name() to avoid the class being found via the normal name lookup in the !kvm_enabled() case. Turn kvmppc_host_cpu_def() into the class_init and add an initfn that asserts KVM is in fact enabled. Implement -cpu ? and the QMP equivalent in terms of subclasses. This newly exposes -cpu host to the user, ordered last for -cpu ?. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-07PPC: Bring EPR support closer to realityAlexander Graf8-46/+31
We already used to support the external proxy facility of FSL MPICs, but only implemented it halfway correctly. This patch adds support for * dynamic enablement of the EPR facility * interrupt acknowledgement only when the interrupt is delivered This way the implementation now is closer to real hardware.

2013-01-07PPC: KVM: set has-idle in guest device treeStuart Yoder3-6/+36
On e500mc, the platform doesn't provide a way for the CPU to go idle. To still not uselessly burn CPU time, expose an idle hypercall to the guest if kvm supports it.

2013-01-07openpic: fix CTPR and de-assertion of interruptsScott Wood1-58/+123
Properly implement level-triggered interrupts by withdrawing an interrupt from the raised queue if the interrupt source de-asserts. Also withdraw from the raised queue if the interrupt becomes masked. When CTPR is written, check whether we need to raise or lower the interrupt output.

2013-01-07openpic: move IACK to its own functionScott Wood1-42/+53
Besides making the code cleaner, we will need a separate way to access IACK in order to implement EPR (external proxy) interrupt delivery. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
