| * | ppc4xx_sdram: QOM'ifyBALATON Zoltan2022-10-175-65/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the ppc4xx_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr. This is mostly modelling the DDR SDRAM controller found in the 440EP (used on the bamboo board) but also backward compatible with the older DDR controllers on some 405 SoCs so we also use it for those now. This likely does not cause problems for guests we run as the new features are just not accessed but to model 405 SoC accurately some features may have to be disabled or the model split between 440 and older. Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an updated DDR2 SDRAM controller implemented by the ppc440_sdram model (only partially, enough for the 460EX on the sam460ex) that is not yet QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2 when QOM'ified later.

* | hw/riscv: virt: Enable booting S-mode firmware from pflashSunil V L2022-10-142-1/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To boot S-mode firmware payload like EDK2 from persistent flash storage, qemu needs to pass the flash address as the next_addr in fw_dynamic_info to the opensbi. When both -kernel and -pflash options are provided in command line, the kernel (and initrd if -initrd) will be copied to fw_cfg table. The S-mode FW will load the kernel/initrd from fw_cfg table. If only pflash is given but not -kernel, then it is the job of of the S-mode firmware to locate and load the kernel. In either case, update the kernel_entry with the flash address so that the opensbi can jump to the entry point of the S-mode firmware.

[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 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.

| * | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `started` field is manipulated internally within the vhost code except for one place, vhost-user-blk via f5b22d06fb (vhost: recheck dev state in the vhost_migration_log routine). Mark that as a FIXME because it introduces a potential race. I think the referenced fix should be tracking its state locally.
