2025-06-23memory: Export a helper to get intersection of a MemoryRegionSection with a ↵Chenyi Qiang1-0/+30
given range Rename the helper to memory_region_section_intersect_range() to make it more generic. Meanwhile, define the @end as Int128 and replace the related operations with Int128_* format since the helper is exported as a wider API.

2025-06-06i386/kvm: Prefault memory on page state changeTom Lendacky1-0/+1
A page state change is typically followed by an access of the page(s) and results in another VMEXIT in order to map the page into the nested page table. Depending on the size of page state change request, this can generate a number of additional VMEXITs. For example, under SNP, when Linux is utilizing lazy memory acceptance, memory is typically accepted in 4M chunks. A page state change request is submitted to mark the pages as private, followed by validation of the memory. Since the guest_memfd currently only supports 4K pages, each page validation will result in VMEXIT to map the page, resulting in 1024 additional exits. When performing a page state change, invoke KVM_PRE_FAULT_MEMORY for the size of the page state change in order to pre-map the pages and avoid the additional VMEXITs. This helps speed up boot times.

2025-06-05vfio/iommufd: Save vendor specific device infoZhenzhong Duan1-0/+15
Some device information returned by ioctl(IOMMU_GET_HW_INFO) are vendor specific. Save them as raw data in a union supporting different vendors, then vendor IOMMU can query the raw data with its fixed format for capability directly. Because IOMMU_GET_HW_INFO is only supported in linux, so declare those capability related structures with CONFIG_LINUX.

2025-06-05vfio/iommufd: Add properties and handlers to TYPE_HOST_IOMMU_DEVICE_IOMMUFDZhenzhong Duan1-0/+50
Enhance HostIOMMUDeviceIOMMUFD object with 3 new members, specific to the iommufd BE + 2 new class functions. IOMMUFD BE includes IOMMUFD handle, devid and hwpt_id. IOMMUFD handle and devid are used to allocate/free ioas and hwpt. hwpt_id is used to re-attach IOMMUFD backed device to its default VFIO sub-system created hwpt, i.e., when vIOMMU is disabled by guest. These properties are initialized in hiod::realize() after attachment. 2 new class functions are [at|de]tach_hwpt(). They are used to attach/detach hwpt. VFIO and VDPA can have different implementions, so implementation will be in sub-class instead of HostIOMMUDeviceIOMMUFD, e.g., in HostIOMMUDeviceIOMMUFDVFIO. Add two wrappers host_iommu_device_iommufd_[at|de]tach_hwpt to wrap the two functions.

Modify memory_get_xlat_addr and vfio_get_xlat_addr to return the memory region that the translated address is found in. This will be needed by CPR in a subsequent patch to map blocks using IOMMU_IOAS_MAP_FILE. Also return the xlat offset, so we can simplify the interface by removing the out parameters that can be trivially derived from mr and xlat. Lastly, rename the functions to to memory_translate_iotlb() and vfio_translate_iotlb().

2025-05-14vhost-user: return failure if backend crash when live migrationHaoqian He1-1/+1
Live migration should be terminated if the vhost-user backend crashes before the migration completes. Specifically, since the vhost device will be stopped when VM is stopped before the end of the live migration, in current implementation if the backend crashes, vhost-user device set_status() won't return failure, live migration won't perceive the disconnection between QEMU and the backend. When the VM is migrated to the destination, the inflight IO will be resubmitted, and if the IO was completed out of order before, it will cause IO error. To fix this issue: 1. Add the return value to set_status() for VirtioDeviceClass. a. For the vhost-user device, return failure when the backend crashes. b. For other virtio devices, always return 0. 2. Return failure if vhost_dev_stop() failed for vhost-user device. If QEMU loses connection with the vhost-user backend, virtio set_status() can return failure to the upper layer, migration_completion() can handle the error, terminate the live migration, and restore the VM, so that inflight IO can be completed normally.

This patch adds the new VM state change cb type `VMChangeStateHandlerWithRet`, which has return value for `VMChangeStateEntry`. Thus, we can register a new VM state change cb with return value for device. Note that `VMChangeStateHandler` and `VMChangeStateHandlerWithRet` are mutually exclusive and cannot be provided at the same time. This patch is the pre patch for 'vhost-user: return failure if backend crashes when live migration', which makes the live migration aware of the loss of connection with the vhost-user backend and aborts the live migration. Virtio device will use VMChangeStateHandlerWithRet.

2025-03-13dma: use current AioContext for dma_blk_io()Stefan Hajnoczi1-2/+1
In the past a single AioContext was used for block I/O and it was fetched using blk_get_aio_context(). Nowadays the block layer supports running I/O from any AioContext and multiple AioContexts at the same time. Remove the dma_blk_io() AioContext argument and use the current AioContext instead. This makes calling the function easier and enables multiple IOThreads to use dma_blk_io() concurrently for the same block device.

2025-03-06accel: Forward-declare AccelOpsClass in 'qemu/typedefs.h'Philippe Mathieu-Daudé2-3/+0
The heavily imported "system/cpus.h" header includes "accel-ops.h" to get AccelOpsClass type declaration. Reduce headers pressure by forward declaring it in "qemu/typedefs.h", where we already declare the AccelCPUState type. Reduce "system/cpus.h" inclusions by only including "system/accel-ops.h" when necessary.

2025-02-24hw: Centralize handling of -machine dumpdtb optionPeter Maydell1-2/+0
Currently we handle the 'dumpdtb' machine sub-option ad-hoc in every board model that has an FDT. It's up to the board code to make sure it calls qemu_fdt_dumpdtb() in the right place. This means we're inconsistent and often just ignore the user's command line argument: * if the board doesn't have an FDT at all * if the board supports FDT, but there happens not to be one present (usually because of a missing -fdt option) This isn't very helpful because it gives the user no clue why their option was ignored. However, in order to support the QMP/HMP dumpdtb commands we require now that every FDT machine stores a pointer to the FDT in MachineState::fdt. This means we can handle -machine dumpdtb centrally by calling the qmp_dumpdtb() function, unifying its handling with the QMP/HMP commands. All the board code calls to qemu_fdt_dumpdtb() can then be removed. For this commit we retain the existing behaviour that if there is no FDT we silently ignore the -machine dumpdtb option.

2025-02-12overcommit: introduce mem-lock=on-faultDaniil Tatianin1-0/+2
Locking the memory without MCL_ONFAULT instantly prefaults any mmaped anonymous memory with a write-fault, which introduces a lot of extra overhead in terms of memory usage when all you want to do is to prevent kcompactd from migrating and compacting QEMU pages. Add an option to only lock pages lazily as they're faulted by the process by using MCL_ONFAULT if asked.
