2025-07-03vfio/container: Fix vfio_container_post_load()Zhenzhong Duan1-3/+4
When there are multiple VFIO containers, vioc->dma_map is restored multiple times, this made only first container work and remaining containers using vioc->dma_map restored by first container. Fix it by save and restore vioc->dma_map locally. saved_dma_map in VFIOContainerCPR becomes useless and is removed.

2025-07-02plugins: Add enforcement of QEMU_PLUGIN_CB flags in register R/W callbacksRowan Hart1-0/+1
This patch adds functionality to enforce the requested QEMU_PLUGIN_CB_ flags level passed when registering a callback function using the plugins API. Each time a callback is about to be invoked, a thread-local variable will be updated with the level that callback requested. Then, called API functions (in particular, the register read and write API) will call qemu_plugin_get_cb_flags() to check the level is at least the level they require.

Implement the Service-Call Logical Processor (SCLP) event type Control-Program Identification (CPI) in QEMU. This event is used to send CPI identifiers from the guest to the host. The CPI identifiers are: system type, system name, system level and sysplex name. System type: operating system of the guest (e.g. "LINUX "). System name: user configurable name of the guest (e.g. "TESTVM "). System level: distribution and kernel version, if the system type is Linux (e.g. 74872343805430528). Sysplex name: name of the cluster which the guest belongs to (if any) (e.g. "PLEX"). The SCLP event CPI is supported only from "s390-ccw-virtio-10.1" machine and higher.

2025-06-13hw/arm: make cpu targeted by arm_load_kernel the primary CPU.Clément Chigot1-0/+3
Currently, arm booting processus assumes that the first_cpu is the CPU that will boot: `arm_load_kernel` is powering off all but the `first_cpu`; `do_cpu_reset` is setting the loader address only for this `first_cpu`. For most of the boards, this isn't an issue as the kernel is loaded and booted on the first CPU anyway. However, for zynqmp, the option "boot-cpu" allows to choose any CPUs. Create a new arm_boot_info entry `primary_cpu` recording which CPU will be boot first. This one is set when `arm_boot_kernel` is called.

2025-06-11vfio/container: recover from unmap-all-vaddr failureSteve Sistare2-0/+13
If there are multiple containers and unmap-all fails for some container, we need to remap vaddr for the other containers for which unmap-all succeeded. Recover by walking all address ranges of all containers to restore the vaddr for each. Do so by invoking the vfio listener callback, and passing a new "remap" flag that tells it to restore a mapping without re-allocating new userland data structures.

2025-06-11vfio/container: restore DMA vaddrSteve Sistare1-0/+3
In new QEMU, do not register the memory listener at device creation time. Register it later, in the container post_load handler, after all vmstate that may affect regions and mapping boundaries has been loaded. The post_load registration will cause the listener to invoke its callback on each flat section, and the calls will match the mappings remembered by the kernel. The listener calls a special dma_map handler that passes the new VA of each section to the kernel using VFIO_DMA_MAP_FLAG_VADDR. Restore the normal handler at the end.

2025-06-11vfio/container: preserve descriptorsSteve Sistare1-0/+6
At vfio creation time, save the value of vfio container, group, and device descriptors in CPR state. On qemu restart, vfio_realize() finds and uses the saved descriptors. During reuse, device and iommu state is already configured, so operations in vfio_realize that would modify the configuration, such as vfio ioctl's, are skipped. The result is that vfio_realize constructs qemu data structures that reflect the current state of the device.
