Nvidia patents software link that lets devices share memory safely
Nvidia describes a software interface that allows one computer chip to share its memory with another. The system uses a specific command to register this shared memory, including a setting that prevents the second chip from changing the data while the first chip still has control.
In the filing’s own words
Apparatuses, systems, and techniques to facilitate storage allocation. In at least one embodiment, an application programming interface is used to execute instructions to cause storage to be allocated based on an indication of whether the storage may be modified.
What exactly they claim (claim 1)
1. One or more processors, comprising: circuitry configured to: in response to an application programming interface (“API”) call comprising one or more parameters comprising a location of storage on a first device to be registered to a second device and an indication of a storage modifiability status for the second device, cause the storage to be registered to the second device based, at least in part, on the one or more parameters; and cause the second device to access the storage according to the one or more parameters and a mapping of the storage into an address space of the second device such that the storage modifiability status is to restrict the second device from modifying the storage while the storage remains modifiable by the first device.
