Filed:

May 10, 2022

Appl. No.:

17/740565

Inventors:

- Mountain View CA, US
Ian Mclaren - Moutain View CA, US
Jon Olson - Seattle WA, US
Jacob Adriaens - Madison WI, US

International Classification:

G06F 11/14
G06F 9/455
G06F 12/10

Abstract:

Systems and methods of error handling in a network interface card (NIC) are provided. For a data packet destined for a local virtual machine (VM), if the NIC cannot determine a valid translation memory address for a virtual memory address in a buffer descriptor from a receive queue of the VM, the NIC can retrieve a backup buffer descriptor from a hypervisor queue, and store the packet in a host memory location indicated by an address in the backup buffer descriptor. For a transmission request from a local VM, if the NIC cannot determine a valid translated address for a virtual memory address in the packet descriptor from a transmit queue of the VM, the NIC can send a message to a hypervisor backup queue, and generate and transmit a data packet based on data in a memory page reallocated by the hypervisor.
