2019-08-21hw: add compat machines for 4.2Cornelia Huck
Add 4.2 machine types for arm/i440fx/q35/s390x/spapr. For i440fx and q35, unversioned cpu models are still translated to -v1, as 0788a56bd1ae ("i386: Make unversioned CPU models be aliases") states this should only transition to the latest cpu model version in 4.3 (or later).

2019-08-16Include hw/boards.h a bit lessMarkus Armbruster
hw/boards.h pulls in almost 60 headers. The less we include it into headers, the better. As a first step, drop superfluous inclusions, and downgrade some more to what's actually needed. Gets rid of just one inclusion into a header.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).

2019-07-05i386: Make unversioned CPU models be aliasesEduardo Habkost
This will make unversioned CPU models behavior depend on the machine type: * "pc-*-4.0" and older will not report them as aliases. This is done to keep compatibility with older QEMU versions after management software starts translating aliases. * "pc-*-4.1" will translate unversioned CPU models to -v1. This is done to keep compatibility with existing management software, that still relies on CPU model runnability promises. * "none" will translate unversioned CPU models to their latest version. This is planned become the default in future machine types (probably in pc-*-4.3).

2019-06-21hw: Nuke hw_compat_4_0_1 and pc_compat_4_0_1Greg Kurz
Commit c87759ce876a fixed a regression affecting pc-q35 machines by introducing a new pc-q35-4.0.1 machine version to be used instead of pc-q35-4.0. The only purpose was to revert the default behaviour of not using split irqchip, but the change also introduced the usual hw_compat and pc_compat bits, and wired them for pc-q35 only. This raises questions when it comes to add new compat properties for 4.0* machine versions of any architecture. Where to add them ? In 4.0, 4.0.1 or both ? Error prone. Another possibility would be to teach all other architectures about 4.0.1. This solution isn't satisfying, especially since this is a pc-q35 specific issue. It turns out that the split irqchip default is handled in the machine option function and doesn't involve compat lists at all. Drop all the 4.0.1 compat lists and use the 4.0 ones instead in the 4.0.1 machine option function. Move the compat props that were added to the 4.0.1 since c87759ce876a to 4.0. Even if only hw_compat_4_0_1 had an impact on other architectures, drop pc_compat_4_0_1 as well for consistency.

2019-06-03q35: Revert to kernel irqchipAlex Williamson
Commit b2fc91db8447 ("q35: set split kernel irqchip as default") changed the default for the pc-q35-4.0 machine type to use split irqchip, which turned out to have disasterous effects on vfio-pci INTx support. KVM resampling irqfds are registered for handling these interrupts, but these are non-functional in split irqchip mode. We can't simply test for split irqchip in QEMU as userspace handling of this interrupt is a significant performance regression versus KVM handling (GeForce GPUs assigned to Windows VMs are non-functional without forcing MSI mode or re-enabling kernel irqchip). The resolution is to revert the change in default irqchip mode in the pc-q35-4.1 machine and create a pc-q35-4.0.1 machine for the 4.0-stable branch. The qemu-q35-4.0 machine type should not be used in vfio-pci configurations for devices requiring legacy INTx support without explicitly modifying the VM configuration to use kernel irqchip.

As NVDIMM support is looming for ARM and SPAPR, let's move the acpi_nvdimm_state to the generic machine struct instead of duplicating the same code in several machines. It is also renamed into nvdimms_state and becomes a pointer. nvdimm and nvdimm-persistence become generic machine options. They become guarded by a nvdimm_supported machine class member.

2018-12-20q35: set split kernel irqchip as defaultPeter Xu
Starting from QEMU 4.0, let's specify "split" as the default value for kernel-irqchip. So for QEMU>=4.0 we'll have: allowed=Y,required=N,split=Y for QEMU<=3.1 we'll have: allowed=Y,required=N,split=N (omitting all the "kernel_irqchip_" prefix) Note that this will let the default q35 machine type to depend on Linux version 4.4 or newer because that's where split irqchip is introduced in kernel. But it's fine since we're boosting supported Linux version for QEMU 4.0 to around Linux 4.5.

2018-06-12object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalenceMarc-André Lureau
A link property can be set during creation, with object_property_add_link() and later with object_property_set_link(). add_link() doesn't add a reference to the target object, while set_link() does. Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released. Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG and use that has an indication on how the link handle reference management in set_link().

2018-03-12q35: change default NIC to e1000ePaolo Bonzini
The e1000 NIC is getting old and is not a very good default for a PCIe machine type. Change it to e1000e, which should be supported by a good number of guests. In particular, drivers for 82574 were added first to Linux 2.6.27 (2008) and Windows 2008 R2. This does mean that Windows 2008 will not work anymore with Q35 machine types and a default "-net nic -net xxx" network configuration; it did work before because it does have an AHCI driver. However, Windows 2008 has been declared out of main stream support in 2015. It will get out of extended support in 2020. Windows 2008 R2 has the same end of support dates and, since the two are basically Vista vs. Windows 7, R2 probably is more popular.

2018-03-06scsi: Remove automatic creation of SCSI controllers with -drive if=scsiThomas Huth
Automatic creation of SCSI controllers for "-drive if=scsi" for x86 machines was quite a bad idea (see description of commit f778a82f0c179 for details). This is marked as deprecated since QEMU v2.9.0, and as far as I know, nobody complained that this is still urgently required anymore. Time to remove this now.

2018-02-09Include qapi/error.h exactly where neededMarkus Armbruster
This cleanup makes the number of objects depending on qapi/error.h drop from 1910 (out of 4743) to 1612 in my "build everything" tree. While there, separate #include from file comment with a blank line, and drop a useless comment on why qemu/osdep.h is included first.

2018-01-19q35: Allow only supported dynamic sysbus devicesEduardo Habkost
The only user-creatable sysbus devices in qemu-system-x86_64 are amd-iommu, intel-iommu, and xen-backend. xen-backend is handled by xen_set_dynamic_sysbus(), so we only need to add amd-iommu and intel-iommu.

2018-01-19machine: Replace has_dynamic_sysbus with list of allowed devicesEduardo Habkost
The existing has_dynamic_sysbus flag makes the machine accept every user-creatable sysbus device type on the command-line. Replace it with a list of allowed device types, so machines can easily accept some sysbus devices while rejecting others. To keep exactly the same behavior as before, the existing has_dynamic_sysbus=true assignments are replaced with a TYPE_SYS_BUS_DEVICE entry on the allowed list. Other patches will replace the TYPE_SYS_BUS_DEVICE entries with more specific lists of devices. Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: "Michael S.

2017-11-16NUMA: Enable adding NUMA node implicitlyDou Liyang
Linux and Windows need ACPI SRAT table to make memory hotplug work properly, however currently QEMU doesn't create SRAT table if numa options aren't present on CLI. Which breaks both linux and windows guests in certain conditions: * Windows: won't enable memory hotplug without SRAT table at all * Linux: if QEMU is started with initial memory all below 4Gb and no SRAT table present, guest kernel will use nommu DMA ops, which breaks 32bit hw drivers when memory is hotplugged and guest tries to use it with that drivers. Fix above issues by automatically creating a numa node when QEMU is started with memory hotplug enabled but without '-numa' options on CLI. (PS: auto-create numa node only for new machine types so not to break migration). Which would provide SRAT table to guests without explicit -numa options on CLI and would allow: * Windows: to enable memory hotplug * Linux: switch to SWIOTLB DMA ops, to bounce DMA transfers to 32bit allocated buffers that legacy drivers/hw can handle.
