device_helpers 🔒

ext2 🔒

Provides a function to lanunches a process of creating ext2 filesystem on memory region asynchronously for pmem-ext2 device.

gpu 🔒

GPU related things depends on “gpu” feature

jail_warden 🔒

Manages minijails creation after VM starts. Minijail is created during a device hotplug.

pci_hotplug_helpers 🔒

Helper functions for PCI hotplug.

pci_hotplug_manager 🔒

A high-level manager for hotplug PCI devices.

vcpu 🔒

Structs

AddressedProtoTube 🔒

ControlLoopState 🔒

HotPlugStub 🔒

Collection of devices related to PCI hotplug.

VmRequestResult 🔒

Enums

ExitState

IrqHandlerToken 🔒

PvClockAction 🔒

The action requested by the pvclock device to perform on the main thread.

VmMemoryHandlerRequest

Commands to control the VM Memory handler thread.

Functions

add_hotplug_device 🔒

add_hotplug_net 🔒

create_devices 🔒

create_guest_memory 🔒

create_mmio_file_backed_mappings 🔒

create_pure_virtual_pcie_root_port 🔒

Creates PCIE root port with only virtual devices.

create_virtio_devices 🔒

find_registered_tube 🔒

get_default_hypervisor 🔒

Choose a default hypervisor if no --hypervisor option was specified.

get_hp_bus 🔒

get_representative_pcpu 🔒

For vcpu_id, return the pcpu that it’s affined to. It’s considered the “representative” pcpu since there could be multiple pcpu’s affined to a single vcpu, so arbitrarily return the first pcpu we see. This “shouldn’t” be an issue since ideally all the affined pcpu’s have the same capacity, frequency, etc.

handle_hotplug_command 🔒

handle_hotplug_net_add 🔒

handle_hotplug_net_command 🔒

handle_hotplug_net_remove 🔒

handle_irq_tube_request 🔒

irq_handler_thread 🔒

Handles IRQs and requests from devices to add additional IRQ lines.

jail_and_start_vu_device 🔒

Start and jail a vhost-user device according to its configuration and a vhost listener string.

make_addr_tube_from_maybe_existing 🔒

map_vcpu_capacity 🔒

Given vcpu_affinity (vcpu->pcpu mapping) and host_capacity (pcpu->pcpu capacity mapping), return a mapping of vcpu->pcpu’s capacity.

map_vcpu_clusters 🔒

Given vcpu_affinity (vcpu->pcpu mapping) and host_clusters (cluster->pcpu mapping), return a mapping of cluster->vcpu mapping.

process_vhost_user_control_request 🔒

process_vm_control_event 🔒

process_vm_request 🔒

punch_holes_in_guest_mem_layout_for_mappings 🔒

remove_hotplug_bridge 🔒

remove_hotplug_device 🔒

remove_hungup_and_drained_tubes 🔒

When control tubes hang up, we want to make sure that we’ve fully drained the underlying socket before removing it. This function also handles removing closed sockets in such a way that avoids phantom events.

run_config

run_control 🔒

run_kvm 🔒

run_vm 🔒

send_pvclock_cmd 🔒

setup_emulator_crash_reporting

Setup crash reporting for a process. Each process MUST provide a unique product_type to avoid making crash reports incomprehensible.
