Enum MemControllerRequest

pub enum MemControllerRequest {
    GetMemSize {
        responder: MemControllerGetMemSizeResponder,
    },
    RequestSize {
        requested_size: u64,
        control_handle: MemControllerControlHandle,
    },
}

A MemController controls a guest’s virtio-mem

Variants

GetMemSize

Get the configured region size, usable region size, plugged size and requestd size

block_size is the size and the alignment in bytes of a memory block. Cannot change. region_size is the size of device-managed memory region in bytes. Cannot change. usable_region_size is the size of the usable device-managed memory region. Can grow up to the region_size. Can only shrink due to VIRTIO_MEM_REQ_UNPLUG_ALL requests. plugged_size is the amount of plugged memory in bytes within the usable device-managed memory region. requested_size is the requested amount of plugged memory within the usable device-managed memory region.

Fields

responder: MemControllerGetMemSizeResponder

RequestSize

Update the requested size to plug or unplug memory

The driver SHOULD react to resize requests from the device (requested_size in the device configuration changed) by (un)plugging memory blocks.

Fields

requested_size: u64

control_handle: MemControllerControlHandle
