Virtual interrupt delivery from a graphics processing unit (gpu) of a computing system without hardware support therefor

A non-transitory medium, readable through a computing system and including instructions embodied therein that are executable through the computing system, comprising:

• instructions to load a driver component on a hypervisor of the computing system including a GPU without hardware support for virtual interrupt delivery, the hypervisor being configured to consolidate a plurality of VMs on a computing platform of the computing system including the GPU and to virtualize resources thereof;
• instructions to load an instance of the driver component on each of the plurality of VMs;
• instructions to allocate a memory page associated with work completion by the each of the plurality of VMs thereto through a driver stack executing on the hypervisor;
• instructions to share the memory page with the driver component executing on the hypervisor;
• and
• instructions to deliver, through the hypervisor, an interrupt from the GPU to an appropriate VM based on inspecting the memory page associated with the work completion by the each of the plurality of VMs.

A computing system comprising:

• a memory;
• a GPU without hardware support for virtual interrupt delivery;
• and
• a hypervisor configured to consolidate a plurality of VMs on a computing platform of the computing system including the GPU and to virtualize resources thereof, the hypervisor including a driver component loaded thereon, each of the plurality of VMs executing an instance of the driver component loaded thereon, the hypervisor executing a driver stack configured to allocate a memory page associated with work completion by the each of the plurality of VMs thereto and to share the memory page with the driver component executing thereon, and the hypervisor further being configured to deliver an interrupt from the GPU to an appropriate VM based on inspecting the memory page associated with the work completion by the each of the plurality of VMs.
