Logging HIP activity#
HIP provides a logging mechanism that allows you to trace HIP API and runtime codes when running a HIP application. In addition to being useful to our users/developers, the HIP development team uses these logs to improve the HIP runtime.
By adjusting the logging settings and logging mask, you can get different types of information for different functionalities, such as HIP APIs, executed kernels, queue commands, and queue contents. Refer to the following sections for examples.
Tip
Logging works for the release and debug versions of HIP. If you want to save logging output in a file, define the file when running the application via command line. For example:
user@user-test:~/hip/bin$ ./hipinfo > ~/hip_log.txt
Logging level#
HIP logging is disabled by default. You can enable it via the AMD_LOG_LEVEL environment variable.
The value of this variable controls your logging level. Levels are defined as follows:
enum LogLevel {
LOG_NONE = 0,
LOG_ERROR = 1,
LOG_WARNING = 2,
LOG_INFO = 3,
LOG_DEBUG = 4
};
Tip
You can call a logging function with different logging levels. All information under the value set for
AMD_LOG_LEVEL is printed.
Logging mask#
The logging mask is designed to print functionality types when you’re running a HIP application.
Once you set AMD_LOG_LEVEL, the logging mask is set as the default value (0x7FFFFFFF). You can
change this to any of the valid values:
enum LogMask {
LOG_API = 0x00000001, //!< API call
LOG_CMD = 0x00000002, //!< Kernel and Copy Commands and Barriers
LOG_WAIT = 0x00000004, //!< Synchronization and waiting for commands to finish
LOG_AQL = 0x00000008, //!< Decode and display AQL packets
LOG_QUEUE = 0x00000010, //!< Queue commands and queue contents
LOG_SIG = 0x00000020, //!< Signal creation, allocation, pool
LOG_LOCK = 0x00000040, //!< Locks and thread-safety code.
LOG_KERN = 0x00000080, //!< kernel creations and arguments, etc.
LOG_COPY = 0x00000100, //!< Copy debug
LOG_COPY2 = 0x00000200, //!< Detailed copy debug
LOG_RESOURCE = 0x00000400, //!< Resource allocation, performance-impacting events.
LOG_INIT = 0x00000800, //!< Initialization and shutdown
LOG_MISC = 0x00001000, //!< misc debug, not yet classified
LOG_AQL2 = 0x00002000, //!< Show raw bytes of AQL packet
LOG_CODE = 0x00004000, //!< Show code creation debug
LOG_CMD2 = 0x00008000, //!< More detailed command info, including barrier commands
LOG_LOCATION = 0x00010000, //!< Log message location
LOG_MEM = 0x00020000, //!< Memory allocation
LOG_MEM_POOL = 0x00040000, //!< Memory pool allocation, including memory in graphs
LOG_ALWAYS = 0xFFFFFFFF, //!< Log always even mask flag is zero
};
You can also define the logging mask via the AMD_LOG_MASK environment variable.
Logging command#
You can use the following code to print HIP logging information:
#define ClPrint(level, mask, format, ...) \
do { \
if (AMD_LOG_LEVEL >= level) { \
if (AMD_LOG_MASK & mask || mask == amd::LOG_ALWAYS) { \
if (AMD_LOG_MASK & amd::LOG_LOCATION) { \
amd::log_printf(level, __FILENAME__, __LINE__, format, ##__VA_ARGS__);\
} else { \
amd::log_printf(level, "", 0, format, ##__VA_ARGS__); \
} \
} \
} \
} while (false)
Using HIP code, call the ClPrint() function with the desired input variables. For example:
ClPrint(amd::LOG_INFO, amd::LOG_INIT, "Initializing HSA stack.");
Logging examples#
On Linux, you can enable HIP logging and retrieve logging information when you run hipinfo.

On Windows, you can set AMD_LOG_LEVEL via environment variable from the advanced system
settings or the command prompt (when run as administrator). The following example shows debug log
information when calling the backend runtime.
C:\hip\bin>set AMD_LOG_LEVEL=4
