| | | | | | | | | | | | | | | | | | | | | | | | | | This new command lists all the instances of VirtIODevices with their canonical QOM path and name. [Jonah: @virtio_list duplicates information that already exists in the QOM composition tree. However, extracting necessary information from this tree seems to be a bit convoluted. Instead, we still create our own list of realized virtio devices but use @qmp_qom_get with the device's canonical QOM path to confirm that the device exists and is realized. If the device exists but is actually not realized, then we remove it from our list (for synchronicity to the QOM composition tree). Also, the QMP command @x-query-virtio is redundant as @qom-list and @qom-get are sufficient to search '/machine/' for realized virtio devices. However, @x-query-virtio is much more convenient in listing realized virtio devices.] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-2-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

* Revert "intel_iommu: Fix irqchip / X2APIC configuration checks"Peter Xu2022-10-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's true that when vcpus<=255 we don't require the length of 32bit APIC IDs. However here since we already have EIM=ON it means the hypervisor will declare the VM as x2apic supported (e.g. VT-d ECAP register will have EIM bit 4 set), so the guest should assume the APIC IDs are 32bits width even if vcpus<=255. In short, commit 77250171bdc breaks any simple cmdline that wants to boot a VM with >=9 but <=255 vcpus with: -device intel-iommu,intremap=on For anyone who does not want to enable x2apic, we can use eim=off in the intel-iommu parameters to skip enabling KVM x2apic. This partly reverts commit 77250171bdc02aee106083fd2a068147befa1a38, while keeping the valid bit on checking split irqchip, but revert the other change. One thing to mention is that this patch may break migration compatibility of such VM, however that's probably the best thing we can do, because the old behavior was simply wrong and not working for >8 vcpus. For <=8 vcpus, there could be a light guest ABI change (by enabling KVM x2apic after this patch), but logically it shouldn't affect the migration from working. Also, this is not the 1st commit to change x2apic behavior. Igor provided a full history of how this evolved for the past few years: https://lore.kernel.org/qemu-devel/20220922154617.57d1a1fb@redhat.com/ Relevant commits for reference: fb506e701e ("intel_iommu: reject broken EIM", 2016-10-17) c1bb5418e3 ("target/i386: Support up to 32768 CPUs without IRQ remapping", 2020-12-10) 77250171bd ("intel_iommu: Fix irqchip / X2APIC configuration checks", 2022-05-16) dc89f32d92 ("target/i386: Fix sanity check on max APIC ID / X2APIC enablement", 2022-05-16) We may want to have this for stable too (mostly for 7.1.0 only).

* virtio: introduce VirtIOConfigSizeParams & virtio_get_config_sizeDaniil Tatianin2022-10-073-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first step towards moving all device config size calculation logic into the virtio core code. In particular, this adds a struct that contains all the necessary information for common virtio code to be able to calculate the final config size for a device. This is expected to be used with the new virtio_get_config_size helper, which calculates the final length based on the provided host features. This builds on top of already existing code like VirtIOFeature and virtio_feature_get_config_size(), but adds additional fields, as well as sanity checking so that device-specifc code doesn't have to duplicate it. An example usage would be: static const VirtIOFeature dev_features[] = { {.flags = 1ULL << FEATURE_1_BIT, .end = endof(struct virtio_dev_config, feature_1)}, {.flags = 1ULL << FEATURE_2_BIT, .end = endof(struct virtio_dev_config, feature_2)}, {} }; static const VirtIOConfigSizeParams dev_cfg_size_params = { .min_size = DEV_BASE_CONFIG_SIZE, .max_size = sizeof(struct virtio_dev_config), .feature_sizes = dev_features }; // code inside my_dev_device_realize() size_t config_size = virtio_get_config_size(&dev_cfg_size_params, host_features); virtio_init(vdev, VIRTIO_ID_MYDEV, config_size); Currently every device is expected to write its own boilerplate from the example above in device_realize(), however, the next step of this transition is moving VirtIOConfigSizeParams into VirtioDeviceClass, so that it can be done automatically by the virtio initialization code. All of the users of virtio_feature_get_config_size have been converted to use virtio_get_config_size so it's no longer needed and is removed with this commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't want it to be possible to re-read the RNG seed after ingesting it, because this ruins forward secrecy. Currently, however, the setup data section can just be re-read. Since the kernel is always read after the setup data, use the selection of the kernel as a trigger to re-initialize the RNG seed, just like we do on reboot, to preserve forward secrecy.

In that case, we should return setup_data containing the absolute addresses that are hard coded and determined a priori. This is the case when kernels are loaded by BIOS, for example. In contrast, when setup_data is read as a file, then we shouldn't modify setup_data, since the absolute address will be wrong by definition. This is the case when OVMF loads the image. This allows setup_data to be used like normal, without crashing when EFI tries to use it. (As a small development note, strangely, fw_cfg_add_file_callback() was exported but fw_cfg_add_bytes_callback() wasn't, so this makes that consistent.)

Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that always returned success, raising the possibility of data loss or corruption if the CHS<->LBA translation redirected a write to the wrong sector. * hw/ide/core.c ide_reset(): Reset the logical CHS geometry of the hard disk when the power-on defaults feature is enabled. cmd_specify(): a) New function implementing INITIALIZE_DEVICE_PARAMETERS. b) Ignore calls for empty or ATAPI devices. cmd_set_features(): Implement the power-on defaults enable and disable features. struct ide_cmd_table: Switch WIN_SPECIFY from cmd_nop() to cmd_specify(). ide_init_drive(): Set new fields 'drive_heads' and 'drive_sectors' based upon the actual disk geometry. * include/hw/ide/internal.h struct IDEState: a) Store the actual drive CHS values within the new fields 'drive_heads' and 'drive_sectors.' b) Track whether a soft IDE reset should also reset the logical CHS geometry of the hard disk within the new field 'reset_reverts'.

| * | | hw/ide/core: Clear LBA and drive bits for EXECUTE DEVICE DIAGNOSTICLev Kujawski2022-09-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, cmd_exec_dev_diagnostic relied upon ide_set_signature to clear the device register. While the preservation of the drive bit by ide_set_signature is necessary for the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands, ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE DEVICE DIAGNOSTIC. This deviation was uncovered by the ATACT Device Testing Program written by Hale Landis.

'libvirt' uses it to detect that it should follow new initialization way and this changes things considerably. With this procedure followed, blockdev_init() is not called anymore and thus block_acct_setup() helper is not called. This means in particular that defaults for block accounting statistics are changed and account_invalid/account_failed are actually initialized as false instead of true originally. This commit changes things to match original world. There are the following constraints: * new default value in block_acct_init() is set to true * block_acct_setup() inside blockdev_init() is called before blkconf_apply_backend_options() * thus newly created option in block device properties has precedence if specified Signed-off-by: Denis V.

In QEMU, MSI transactions contain the requester ID, so the PCI node should use the "msi-map" property instead of "msi-parent". In our case the property describes an identity map between requester ID and sideband data. This fixes a warning when passing the DTB generated by QEMU to dtc, following a recent change to the GICv3 node: Warning (msi_parent_property): /pcie@10000000:msi-parent: property size (4) too small for cell size 1 [1] linux/Documentation/devicetree/bindings/pci/pci-msi.txt Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Eric Auger <eric.auger@redhat.com> Message-id: 20220927100347.176606-4-jean-philippe@linaro.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
