- Deprecated:
Note that this function is deprecated because its name does not reflect its behavior. Its functionality is identical to the non-deprecated function
cudaDeviceGetCacheConfig(), which should be used instead.
On devices where the L1 cache and shared memory use the same hardware resources, this returns through pCacheConfig
the preferred cache configuration for the current device. This is only a preference. The runtime will use the requested configuration if possible, but it is free to choose a different configuration if required to execute functions.
This will return a pCacheConfig
of cudaFuncCachePreferNone on devices where the size of the L1 cache and shared memory are fixed.
The supported cache configurations are:
- Parameters:
-
| pCacheConfig | - Returned cache configuration |
- Returns:
- cudaSuccess, cudaErrorInitializationError
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
