Public Methods

void ~MemController ()
void GetMemSize (GetMemSizeCallback callback)

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.

void RequestSize (uint64_t requested_size)

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.
