2024-07-02hw/i386: convert 'i440fx' machine definitions to use new macrosDaniel P. Berrangé
This changes the DEFINE_I440FX_MACHINE macro to use the common helpers for constructing versioned symbol names and strings, bringing greater consistency across targets. The added benefit is that it avoids the need to repeat the version number thrice in three different formats in the calls to DEFINE_I440FX_MACHINE. Signed-off-by: Daniel P.

2024-07-01virtio-pci: implement No_Soft_Reset bitJiqian Chen
In current code, when guest does S3, virtio-gpu are reset due to the bit No_Soft_Reset is not set. After resetting, the display resources of virtio-gpu are destroyed, then the display can't come back and only show blank after resuming. Implement No_Soft_Reset bit of PCI_PM_CTRL register, then guest can check this bit, if this bit is set, the devices resetting will not be done, and then the display can work after resuming. No_Soft_Reset bit is implemented for all virtio devices, and was tested only on virtio-gpu device. Set it false by default for safety.

2024-07-01hw/mem/cxl_type3: Add DPA range validation for accesses to DC regionsFan Ni
All DPA ranges in the DC regions are invalid to access until an extent covering the range has been successfully accepted by the host. A bitmap is added to each region to record whether a DC block in the region has been backed by a DC extent. Each bit in the bitmap represents a DC block. When a DC extent is accepted, all the bits representing the blocks in the extent are set, which will be cleared when the extent is released.

2024-07-01hw/cxl/events: Add qmp interfaces to add/release dynamic capacity extentsFan Ni
To simulate FM functionalities for initiating Dynamic Capacity Add (Opcode 5604h) and Dynamic Capacity Release (Opcode 5605h) as in CXL spec r3.1 7.6.7.6.5 and 7.6.7.6.6, we implemented two QMP interfaces to issue add/release dynamic capacity extents requests. With the change, we allow to release an extent only when its DPA range is contained by a single accepted extent in the device. That is to say, extent superset release is not supported yet. 1. Add dynamic capacity extents: For example, the command to add two continuous extents (each 128MiB long) to region 0 (starting at DPA offset 0) looks like below: { "execute": "qmp_capabilities" } { "execute": "cxl-add-dynamic-capacity", "arguments": { "path": "/machine/peripheral/cxl-dcd0", "host-id": 0, "selection-policy": "prescriptive", "region": 0, "extents": [ { "offset": 0, "len": 134217728 }, { "offset": 134217728, "len": 134217728 } ] } } 2. Release dynamic capacity extents: For example, the command to release an extent of size 128MiB from region 0 (DPA offset 128MiB) looks like below: { "execute": "cxl-release-dynamic-capacity", "arguments": { "path": "/machine/peripheral/cxl-dcd0", "host-id": 0, "removal-policy":"prescriptive", "region": 0, "extents": [ { "offset": 134217728, "len": 134217728 } ] } } Tested-by: Svetly Todorov <svetly.todorov@memverge.com> Reviewed-by: Gregory Price <gregory.price@memverge.com> Signed-off-by: Fan Ni <fan.ni@samsung.com> Message-Id: <20240523174651.1089554-12-nifan.cxl@gmail.com> Reviewed-by: Michael S.

Since the current patch cannot completely fix the lost reconnect problem, there is a scenario that is not considered: - When the virtio-blk driver is removed from the guest os, s->connected has no chance to be set to false, resulting in subsequent reconnection not being executed.

2024-07-01vhost: Perform memory section dirty scans once per iterationSi-Wei Liu
On setups with one or more virtio-net devices with vhost on, dirty tracking iteration increases cost the bigger the number amount of queues are set up e.g. on idle guests migration the following is observed with virtio-net with vhost=on: 48 queues -> 78.11% [.] vhost_dev_sync_region.isra.13 8 queues -> 40.50% [.] vhost_dev_sync_region.isra.13 1 queue -> 6.89% [.] vhost_dev_sync_region.isra.13 2 devices, 1 queue -> 18.60% [.] vhost_dev_sync_region.isra.14 With high memory rates the symptom is lack of convergence as soon as it has a vhost device with a sufficiently high number of queues, the sufficient number of vhost devices. On every migration iteration (every 100msecs) it will redundantly query the *shared log* the number of queues configured with vhost that exist in the guest. For the virtqueue data, this is necessary, but not for the memory sections which are the same. So essentially we end up scanning the dirty log too often. To fix that, select a vhost device responsible for scanning the log with regards to memory sections dirty tracking. It is selected when we enable the logger (during migration) and cleared when we disable the logger. If the vhost logger device goes away for some reason, the logger will be re-selected from the rest of vhost devices. After making mem-section logger a singleton instance, constant cost of 7%-9% (like the 1 queue report) will be seen, no matter how many queues or how many vhost devices are configured: 48 queues -> 8.71% [.] vhost_dev_sync_region.isra.13 2 devices, 8 queues -> 7.97% [.] vhost_dev_sync_region.isra.14 Co-developed-by: Joao Martins <joao.m.martins@oracle.com> Signed-off-by: Joao Martins <joao.m.martins@oracle.com> Signed-off-by: Si-Wei Liu <si-wei.liu@oracle.com> Message-Id: <1710448055-11709-2-git-send-email-si-wei.liu@oracle.com> Reviewed-by: Michael S.

2024-06-28include: move typeof_strip_qual to compiler.h, use it in QAPI_LIST_LENGTH()Paolo Bonzini
The typeof_strip_qual() is most useful for the atomic fetch-and-modify operations in atomic.h, but it can be used elsewhere as well. For example, QAPI_LIST_LENGTH() assumes that the argument is not const, which is not a requirement. Move the macro to compiler.h and, while at it, move it under #ifndef __cplusplus to emphasize that it uses C-only constructs. A C++ version of typeof_strip_qual() using type traits is possible[1], but beyond the scope of this patch because the little C++ code that is in QEMU does not use QAPI. The patch was tested by changing the declaration of strv_from_str_list() in qapi/qapi-type-helpers.c to: char **strv_from_str_list(const strList *const list) This is valid C code, and it fails to compile without this change.

Assign the base container VFIOAddressSpace 'space' pointer in vfio_address_space_insert(). The ultimate goal is to remove vfio_container_init() and instead rely on an .instance_init() handler to perfom the initialization of VFIOContainerBase. To be noted that vfio_connect_container() will assign the 'space' pointer later in the execution flow. This should not have any consequence.
