* hw/i386/pc_piix: Mark the machine types from version 1.4 to 1.7 as deprecatedThomas Huth2022-03-061-0/+1
| | | | | | | | | | | | | | The list of machine types grows larger and larger each release ... and it is unlikely that many people still use the very old ones for live migration. QEMU v1.7 has been released more than 8 years ago, so most people should have updated their machines to a newer version in those 8 years at least once. Thus let's mark the very old 1.x machine types as deprecated now. Signed-off-by: Thomas Huth <thuth@redhat.com> Message-Id: <20220117191639.278497-1-thuth@redhat.com> Reviewed-by: Michael S.

* hw/i386: expose a "smbios-entry-point-type" PC machine propertyEduardo Habkost2022-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The i440fx and Q35 machine types are both hardcoded to use the legacy SMBIOS 2.1 (32-bit) entry point. This is a sensible conservative choice because SeaBIOS only supports SMBIOS 2.1 EDK2, however, can also support SMBIOS 3.0 (64-bit) entry points, and QEMU already uses this on the ARM virt machine type. This adds a property to allow the choice of SMBIOS entry point versions For example to opt in to 64-bit SMBIOS entry point: $QEMU -machine q35,smbios-entry-point-type=64 Based on a patch submitted by Daniel Berrangé.

* smbios: Rename SMBIOS_ENTRY_POINT_* enumsEduardo Habkost2022-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Rename the enums to match the naming style used by QAPI, and to use "32" and "64" instead of "20" and "31". This will allow us to more easily move the enum to the QAPI schema later. About the naming choice: "SMBIOS 2.1 entry point"/"SMBIOS 3.0 entry point" and "32-bit entry point"/"64-bit entry point" are synonymous in the SMBIOS specification. However, the phrases "32-bit entry point" and "64-bit entry point" are used more often. The new names also avoid confusion between the entry point format and the actual SMBIOS version reported in the entry point structure. For example: currently the 32-bit entry point actually report SMBIOS 2.8 support, not 2.1. Based on portions of a patch submitted by Daniel P. Berrangé.

* machine: Prefer cores over sockets in smp parsing since 6.2Yanan Wang2021-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | In the real SMP hardware topology world, it's much more likely that we have high cores-per-socket counts and few sockets totally. While the current preference of sockets over cores in smp parsing results in a virtual cpu topology with low cores-per-sockets counts and a large number of sockets, which is just contrary to the real world. Given that it is better to make the virtual cpu topology be more reflective of the real world and also for the sake of compatibility, we start to prefer cores over sockets over threads in smp parsing since machine type 6.2 for different arches. In this patch, a boolean "smp_prefer_sockets" is added, and we only enable the old preference on older machines and enable the new one since type 6.2 for all arches by using the machine compat mechanism.

* hw/xen: Set suppress-vmdesc for Xen machinesJason Andryuk2020-10-191-2/+2
| | | | | | | | | | | | | | | | | | | | | xen-save-devices-state doesn't currently generate a vmdesc, so restore always triggers "Expected vmdescription section, but got 0". This is not a problem when restore comes from a file. However, when QEMU runs in a linux stubdom and comes over a console, EOF is not received. This causes a delay restoring - though it does restore. Setting suppress-vmdesc skips looking for the vmdesc during restore and avoids the wait. The other approach would be generate a vmdesc in qemu_save_device_state. Since COLO shared that function, and the vmdesc is just discarded on restore, we choose to skip it.

| | | | | | | | | | | | | | | | | | | | QEMU's kvmclock device is only created when KVM PV feature bits for kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are exposed to the guest. With 'kvm=off' cpu flag the device is not created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration. It was reported that without these call at least Hyper-V TSC page clocksouce (which can be enabled independently) gets broken after migration. Switch to creating kvmclock QEMU device unconditionally, it seems to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration. Use KVM_CAP_ADJUST_CLOCK check instead of CPUID feature bits.

The latter however is not called when xen_enable() is true and hence the following assertion fails: qemu-system-i386: hw/core/qdev.c:439: qdev_assert_realized_properly: Assertion `dev->realized' failed These flash devices are unneeded when using Xen so this patch avoids the assertion by simply removing them using pc_system_flash_cleanup_unused().

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's auto-enable it also when maxmem is specified but no slots are defined. This will result in us properly creating ACPI srat tables, indicating the maximum possible PFN to the guest OS. Based on this, e.g., Linux will enable the swiotlb properly. This avoids having to manually force the switolb on (swiotlb=force) in Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64), and virtio-mem adds memory later on that really needs the swiotlb to be used for DMA. Let's take care of backwards compatibility if somebody has a setup that specifies "maxram" without "slots".

* xen: fix build without pci passthroughAnthony PERARD2020-06-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | Xen PCI passthrough support may not be available and thus the global variable "has_igd_gfx_passthru" might be compiled out. Common code should not access it in that case. Unfortunately, we can't use CONFIG_XEN_PCI_PASSTHROUGH directly in xen-common.c so this patch instead move access to the has_igd_gfx_passthru variable via function and those functions are also implemented as stubs. The stubs will be used when QEMU is built without passthrough support. Now, when one will want to enable igd-passthru via the -machine property, they will get an error message if QEMU is built without passthrough support.

* qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster2020-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

* piix: fix xenfv regression, add compat machine xenfv-4.2Olaf Hering2020-04-111-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With QEMU 4.0 an incompatible change was added to pc_piix, which makes it practical impossible to migrate domUs started with qemu2 or qemu3 to newer qemu versions. Commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea added and enabled a new member "smbus_no_migration_support". In commit 4ab2f2a8aabfea95cc53c64e13b3f67960b27fdf the vmstate_acpi got new elements, which are conditionally filled. As a result, an incoming migration expected smbus related data unless smbus migration was disabled for a given MachineClass. Since first commit forgot to handle 'xenfv', domUs started with QEMU 4.x are incompatible with their QEMU siblings. Using other existing machine types, such as 'pc-i440fx-3.1', is not possible because 'xenfv' creates the 'xen-platform' PCI device at 00:02.0, while all other variants to run a domU would create it at 00:04.0. To cover both the existing and the broken case of 'xenfv' in a single qemu binary, a new compatibility variant of 'xenfv-4.2' must be added which targets domUs started with qemu 4.2. The existing 'xenfv' restores compatibility of QEMU 5.x with qemu 3.1. Host admins who started domUs with QEMU 4.x (preferrable QEMU 4.2) have to use a wrapper script which appends '-machine xenfv-4.2' to the device-model command line. This is only required if there is no maintenance window which allows to temporary shutdown the domU and restart it with a fixed device-model. The wrapper script is as simple as this: #!/bin/sh exec /usr/bin/qemu-system-i386 "$@" -machine xenfv-4.2 With xl this script will be enabled with device_model_override=, see xl.cfg(5). To live migrate a domU, adjust the existing domU.cfg and pass it to xl migrate or xl save/restore: xl migrate -C new-domU.cfg domU remote-host xl save domU CheckpointFile new-domU.cfg xl restore new-domU.cfg CheckpointFile With libvirt this script will be enabled with the <emulator> element in domU.xml. Use 'virsh edit' prior 'virsh migrate' to replace the existing <emulator> element to point it to the wrapper script.
