2022-10-18scsi: Use device_cold_reset() and bus_cold_reset()Peter Maydell7-14/+14
In the SCSI subsystem we currently use the legacy functions qdev_reset_all() and qbus_reset_all(). These perform a recursive reset, starting from either a qbus or a qdev. However they do not permit any of the devices in the tree to use three-phase reset, because device reset goes through the device_legacy_reset() function that only calls the single DeviceClass::reset method. Switch to using the device_cold_reset() and bus_cold_reset() functions. These also perform a recursive reset, where first the children are reset and then finally the parent, but they use the new (...in 2020...) Resettable mechanism, which supports both the old style single-reset method and also the new 3-phase reset handling. Since no devices attached to SCSI buses currently try to use 3-phase reset, this should be a no-behaviour-change commit which just reduces the use of a deprecated API.

2022-10-13virtio-scsi: Send "REPORTED LUNS CHANGED" sense data upon disk hotplug eventsVenu Busireddy2-0/+20
Section 5.6.6.3 of VirtIO specification states, "Events will also be reported via sense codes..." However, no sense data is sent when VIRTIO_SCSI_EVT_RESET_RESCAN or VIRTIO_SCSI_EVT_RESET_REMOVED events are reported (when disk hotplug/hotunplug events occur). SCSI layer on Solaris depends on this sense data, and hence does not handle disk hotplug/hotunplug events. When the disk inventory changes, use the bus unit attention mechanism to return a CHECK_CONDITION status with sense data of 0x06/0x3F/0x0E (sense code REPORTED_LUNS_CHANGED). The first device on the bus to execute a command successfully will report and consume the unit attention status.

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.

2022-10-09Revert "intel_iommu: Fix irqchip / X2APIC configuration checks"Peter Xu1-0/+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).

2022-10-07virtio: introduce VirtIOConfigSizeParams & virtio_get_config_sizeDaniil Tatianin3-15/+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.

This is a heavily used function so lets avoid the cost of CPU_GET_CLASS.

2022-10-04Use g_new() & friends where that makes obvious senseMarkus Armbruster2-2/+2
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Patch created mechanically with: $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \ --macro-file scripts/cocci-macro-file.h FILES... The previous iteration was commit a95942b50c.
