Thanks @sananya12.
I have some minor comments. I don't think any of them are blockers for getting this merged though.

This change adds a script and related files to generate the internal bindings for Sandboxutils library with the help of c-for-go. This can be used to update the bindings when the header file is modified with reference to how they are generated with the Makefile in go-nvml. Run: ./update-bindings.sh Signed-off-by: Evan Lezar <[email protected]> Signed-off-by: Huy Nguyen <[email protected]> Signed-off-by: Sananya Majumder <[email protected]>
This change adds the internal bindings for Sandboxutils, some of which have been automatically generated with the help of c-for-go. The format followed is similar to what is used in go-nvml. These would need to be regenerated when the header file is modified and new APIs are added. Signed-off-by: Evan Lezar <[email protected]> Signed-off-by: Huy Nguyen <[email protected]> Signed-off-by: Sananya Majumder <[email protected]>
This change adds manual wrappers around the generated bindings to make them into more user-friendly APIs for the caller. Some helper functions are also added. The APIs that are currently present in the library and implemented here are: nvSandboxUtilsInit nvSandboxUtilsShutdown nvSandboxUtilsGetDriverVersion nvSandboxUtilsGetGpuResource nvSandboxUtilsGetFileContent Signed-off-by: Evan Lezar <[email protected]> Signed-off-by: Huy Nguyen <[email protected]> Signed-off-by: Sananya Majumder <[email protected]>
This change includes the usage of Sandboxutils GetDriverVersion API to retrieve the CUDA driver version. If the library is not available on the system or the API call fails for some other reason, it will fallback to the NVML API to return the driver version. Signed-off-by: Evan Lezar <[email protected]> Signed-off-by: Huy Nguyen <[email protected]> Signed-off-by: Sananya Majumder <[email protected]>
This change adds a new discoverer for Sandboxutils to report the file system paths and associated symbolic links using GetGpuResource and GetFileContent APIs. Both GPU and MIG devices are supported. If the Sandboxutils discoverer fails, the NVML discoverer is used to report the file system information.
