US Patent:

20220342687, Oct 27, 2022

Filed:

Apr 23, 2021

Appl. No.:

17/239443

Inventors:

- Palo Alto CA, US
Mark Sheldon - Fremont CA, US

International Classification:

G06F 9/455
G06T 1/20
G06F 9/54

Abstract:

Techniques for implementing secure GPU virtualization using sandboxing are provided. In one set of embodiments, a hypervisor of a host system can receive one or more first graphics/compute commands issued by a guest application running within a VM of the host system. The hypervisor can further communicate the one or more first graphics/compute commands to a sandboxed software process that is separate from the hypervisor. The sandboxed software process can then translate the one or more first graphics/compute commands into one or more second graphics/compute commands and issue the one or more second graphics/compute commands for execution on a physical GPU.

Appl. No.:

13/846332

Inventors:

- Palo Alto CA, US
Mark SHELDON - Mountain View CA, US

Assignee:

VMWARE, INC. - Palo Alto CA

International Classification:

G06T 1/20

US Classification:

345522

Abstract:

Exemplary methods, apparatuses, and systems receive a command from a program to render graphics data on a display device, transmit the command to a graphics processing unit (GPU), and transmit a readback request to the GPU. Upon receiving a response to the readback request from the GPU, the program is alerted that the command has been transmitted to the GPU. The response to the readback request is a pointer to a memory location at which the GPU has written rendered frame data representing the command. In response to receiving notification of a failure of the GPU, the rendered frame data written in response to the readback request and any additional commands to render the additional graphics requests received subsequent to the transmission of the readback request are transmitting to the GPU upon recovery from the failure, or to another GPU.

Assignee:

VMWARE, INC. - Palo Alto CA

International Classification:

G06T 1/20

US Classification:

345522

Abstract:

Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS comprises virtualization logic running on a server computing system that computes GPU benefit factors for the virtual machines on a dynamic basis, and combines the computed GBFs with static priorities to determine a ranked ordering of virtual machines. The available GPU resources are then allocated to some subset of these ranked virtual machines as physical GPU capacity is matched with the requirements of the subset. Physical GPU resources are then allocated to the subset of virtual machines that have the highest promise of GPU utilization.

International Classification:

G06F 9/455

US Classification:

718 1

Abstract:

Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS comprises a GPU allocation list for use in allocating the physical GPU resources comprising one or more virtual machine entries each containing a designation of a virtual machine, an indication of a GPU benefit factor associated with the designated virtual machine, and an indication of processing bandwidth requirements associated with the designated virtual machine. The entries are ranked based at least upon the GPU benefit factor associated with each designated virtual machine. Available GPU resources are allocated to some subset of these ranked virtual machines as physical GPU capacity is matched with the requirements of the subset.
