Migrated from oneapi-src/unified-runtime#1748
This PR implements oneapi-src/unified-runtime#1330 through a new logger sink: a user configurable callback. It introduces some spec additions:
typedef void (*ur_logger_output_callback_t)(ur_logger_level_t level, const char *pLoggerMsg, void *pUserData)
urSetLoggerCallback(ur_adapter_handle_t hAdapter, ur_logger_output_callback_t pfnLoggerCallback, void *pUserData, ur_logger_level_t level
)`
urSetLoggerCallbackLevel(ur_adapter_handle_t hAdapter, ur_logger_level_t level)
typedef enum ur_logger_level_t
(moved the logger::level enum into the spec)This new logger sink will only be constructed once a user makes a call to
urSetLoggerCallback
, supplying their own callback function. They can set the minimum logging level throughurSetLoggerCallbackLevel
. Any subsequent logging calls will additionally make a call to the supplied callback where the log level, message and user data will be sent.A new test suite
LoggerWithCallbackSink
has been added to test this new functionality.
