2025-06-26vfio-user: implement VFIO_USER_DMA_MAP/UNMAPJohn Levon5-4/+257
When the vfio-user container gets mapping updates, share them with the vfio-user by sending a message; this can include the region fd, allowing the server to directly mmap() the region as needed. For performance, we only wait for the message responses when we're doing with a series of updates via the listener_commit() callback.

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.

Modify memory_region_set_ram_discard_manager() to return -EBUSY if a RamDiscardManager is already set in the MemoryRegion. The caller must handle this failure, such as having virtio-mem undo its actions and fail the realize() process. Opportunistically move the call earlier to avoid complex error handling. This change is beneficial when introducing a new RamDiscardManager instance besides virtio-mem. After ram_block_coordinated_discard_require(true) unlocks all RamDiscardManager instances, only one instance is allowed to be set for one MemoryRegion at present.

2025-06-16hw/arm/mps2: Configure the AN500 CPU with 16 MPU regionsPeter Maydell1-0/+4
The AN500 application note documents that it configures the Cortex-M7 CPU to have 16 MPU regions. We weren't doing this in our emulation, so the CPU had only the default 8 MPU regions. Set the mpu-ns-regions property to 16 for this board. This bug doesn't affect any of the other board types we model in this source file, because they all use either the Cortex-M3 or Cortex-M4. Those CPUs do not have an RTL configurable number of MPU regions, and always provide 8 regions if the MPU is built in.

2025-06-13hw/arm: make cpu targeted by arm_load_kernel the primary CPU.Clément Chigot1-8/+7
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.
