Abstract
Page faults arising in a graphics processing unit may be handled by an operating system running on the central processing unit. In some embodiments, this means that unpinned memory can be used for the graphics processing unit. Using unpinned memory in the graphics processing unit may expand the capabilities of the graphics processing unit in some cases.
Claims20
A method comprising:
- handling page faults, arising in a first processing unit, by an operating system running on a second processing unit.
A non-transitory computer readable medium storing instructions to enable a first processor to:
- handle page faults, arising in a second processor, using an operating system running on said first processor.
An apparatus comprising:
- a processor to handle page faults arising on another processor;
- and
- a memory coupled to said processor.
The apparatus of claim 20 wherein said processor and said another processor share said unpinned virtual memory.
Dependencies are inferred from the claim text.
