- Adding support for cudaFuncSetCacheConfig API, that allows changing the
L1 Cache and Shared Memory configurations across kernels. The support
enable the user to specify two more configurations (Preferred L1) or
(Preferred Shared Memory) besides the default config. If the
cudaFuncSetCacheConfig API is used to set the cache configuration
of a specific kernel to either of these configuration (cudaFuncCachePreferShared,
cudaFuncCachePreferL1), the simulator will change the cache configuration
at kernel launch accordingly, if there is no alternative configurations
provided to the simulator it will use the default configurations with a
warning message display
