2021-05-14hw/smbios: support for type 41 (onboard devices extended information)Vincent Bernat
Type 41 defines the attributes of devices that are onboard. The original intent was to imply the BIOS had some level of control over the enablement of the associated devices. If network devices are present in this table, by default, udev will name the corresponding interfaces enoX, X being the instance number. Without such information, udev will fallback to using the PCI ID and this usually gives ens3 or ens4. This can be a bit annoying as the name of the network card may depend on the order of options and may change if a new PCI device is added earlier on the commande line. Being able to provide SMBIOS type 41 entry ensure the name of the interface won't change and helps the user guess the right name without booting a first time. This can be invoked with: $QEMU -netdev user,id=internet -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \ -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev The PCI segment is assumed to be 0. This should hold true for most cases. $ dmidecode -t 41 # dmidecode 3.3 Getting SMBIOS data from sysfs. SMBIOS 2.8 present.

2021-04-06hw/arm/virt: Only try to add valid dynamic sysbus devices to platform busPeter Maydell
The virt machine device plug callback currently calls platform_bus_link_device() for any sysbus device. This is overly broad, because platform_bus_link_device() will unconditionally grab the IRQs and MMIOs of the device it is passed, whether it was intended for the platform bus or not. Restrict hotpluggability of sysbus devices to only those devices on the dynamic sysbus allowlist. We were mostly getting away with this because the board creates the platform bus as the last device it creates, and so the hotplug callback did not do anything for all the sysbus devices created by the board itself. However if the user plugged in a device which itself uses a sysbus device internally we would have mishandled this and probably asserted.

2021-03-12hw/arm/virt: KVM: The IPA lower bound is 32Andrew Jones
The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the upper bound of the IPA size. If that bound is lower than the highest possible GPA for the machine, then QEMU will error out. However, the IPA is set to 40 when the highest GPA is less than or equal to 40, even when KVM may support an IPA limit as low as 32. This means KVM may fail the VM creation unnecessarily. Additionally, 40 is selected with the value 0, which means use the default, and that gets around a check in some versions of KVM, causing a difficult to debug fail. Always use the IPA size that corresponds to the highest possible GPA, unless it's lower than 32, in which case use 32. Also, we must still use 0 when KVM only supports the legacy fixed 40 bit IPA.

2021-02-05acpi: Permit OEM ID and OEM table ID fields to be changedMarian Postevca
Qemu's ACPI table generation sets the fields OEM ID and OEM table ID to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI table name. Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID and OEM table ID for the strings "BOCHS" and "BXPC" and if they are found, the game crashes(this may be an intentional detection mechanism to prevent playing the game in a virtualized environment). This patch allows you to override these default values. The feature can be used in this manner: qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN The oem-id string can be up to 6 bytes in size, and the oem-table-id string can be up to 8 bytes in size. If the string are smaller than their respective sizes they will be padded with space. If either of these parameters is not set, the current default values will be used for the one missing. Note that the the OEM Table ID field will not be extended with the name of the table, but will use either the default name or the user provided one. This does not affect the -acpitable option (for user-defined ACPI tables), which has precedence over -machine option.

2020-09-22qom: simplify object_find_property / object_class_find_propertyDaniel P. Berrangé
When debugging QEMU it is often useful to put a breakpoint on the error_setg_internal method impl. Unfortunately the object_property_add / object_class_property_add methods call object_property_find / object_class_property_find methods to check if a property exists already before adding the new property. As a result there are a huge number of calls to error_setg_internal on startup of most QEMU commands, making it very painful to set a breakpoint on this method. Most callers of object_find_property and object_class_find_property, however, pass in a NULL for the Error parameter. This simplifies the methods to remove the Error parameter entirely, and then adds some new wrapper methods that are able to raise an Error when needed. Signed-off-by: Daniel P.

2020-07-10qom: Put name parameter before value / visitor parameterMarkus Armbruster
The object_property_set_FOO() setters take property name and value in an unusual order: void object_property_set_FOO(Object *obj, FOO_TYPE value, const char *name, Error **errp) Having to pass value before name feels grating. Swap them. Same for object_property_set(), object_property_get(), and object_property_parse().

2020-07-03hw/arm/virt-acpi-build: Only expose flash on older machine typesAndrew Jones
The flash device is exclusively for the host-controlled firmware, so we should not expose it to the OS. Exposing it risks the OS messing with it, which could break firmware runtime services and surprise the OS when all its changes disappear after reboot. As firmware needs the device and uses DT, we leave the device exposed there. It's up to firmware to remove the nodes from DT before sending it on to the OS. However, there's no need to force firmware to remove tables from ACPI (which it doesn't know how to do anyway), so we simply don't add the tables in the first place. But, as we've been adding the tables for quite some time and don't want to change the default hardware exposed to versioned machines, then we only stop exposing the flash device tables for 5.1 and later machine types.

2020-07-03hw/arm/virt: Let the virtio-iommu bypass MSIsEric Auger
At the moment the virtio-iommu translates MSI transactions. This behavior is inherited from ARM SMMU. The virt machine code knows where the guest MSI doorbells are so we can easily declare those regions as VIRTIO_IOMMU_RESV_MEM_T_MSI. With that setting the guest will not map MSIs through the IOMMU and those transactions will be simply bypassed. Depending on which MSI controller is in use (ITS or GICV2M), we declare either: - the ITS interrupt translation space (ITS_base + 0x10000), containing the GITS_TRANSLATOR or - The GICV2M single frame, containing the MSI_SETSP_NS register.

2020-07-03numa: Auto-enable NUMA when any memory devices are possibleDavid Hildenbrand
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".
