# Logging Mechanisms
HIP provides a logging mechanism, which is a convenient way of printing
important information so as to trace HIP API and runtime codes during the
execution of HIP application.
It assists HIP development team in the development of HIP runtime, and is useful
for HIP application developers as well.
Depending on the setting of logging level and logging mask, HIP logging will
print different kinds of information, for different types of functionalities
such as HIP APIs, executed kernels, queue commands and queue contents, etc.
## HIP Logging Level:
By default, HIP logging is disabled, it can be enabled via the `AMD_LOG_LEVEL`
environment variable.
The value controls the logging level. The levels are defined as:
```cpp
enum LogLevel {
LOG_NONE = 0,
LOG_ERROR = 1,
LOG_WARNING = 2,
LOG_INFO = 3,
LOG_DEBUG = 4
};
```
## HIP Logging Mask:
Logging mask is designed to print types of functionalities during the execution
of HIP application.
It can be set as one of the following values,
```cpp
enum LogMask {
LOG_API = 1, //!< (0x1) API call
LOG_CMD = 2, //!< (0x2) Kernel and Copy Commands and Barriers
LOG_WAIT = 4, //!< (0x4) Synchronization and waiting for commands to finish
LOG_AQL = 8, //!< (0x8) Decode and display AQL packets
LOG_QUEUE = 16, //!< (0x10) Queue commands and queue contents
LOG_SIG = 32, //!< (0x20) Signal creation, allocation, pool
LOG_LOCK = 64, //!< (0x40) Locks and thread-safety code.
LOG_KERN = 128, //!< (0x80) Kernel creations and arguments, etc.
LOG_COPY = 256, //!< (0x100) Copy debug
LOG_COPY2 = 512, //!< (0x200) Detailed copy debug
LOG_RESOURCE = 1024, //!< (0x400) Resource allocation, performance-impacting events.
LOG_INIT = 2048, //!< (0x800) Initialization and shutdown
LOG_MISC = 4096, //!< (0x1000) Misc debug, not yet classified
LOG_AQL2 = 8192, //!< (0x2000) Show raw bytes of AQL packet
LOG_CODE = 16384, //!< (0x4000) Show code creation debug
LOG_CMD2 = 32768, //!< (0x8000) More detailed command info, including barrier commands
LOG_LOCATION = 65536, //!< (0x10000) Log message location
LOG_MEM = 131072, //!< (0x20000) Memory allocation
LOG_MEM_POOL = 262144, //!< (0x40000) Memory pool allocation, including memory in graphs
LOG_ALWAYS = -1 //!< (0xFFFFFFFF) Log always even mask flag is zero
};
```
Once `AMD_LOG_LEVEL` is set, logging mask is set as default with the value
`-1`.
However, for different purpose of logging functionalities, logging mask can be
defined as well via environment variable `AMD_LOG_MASK`
## HIP Logging command:
To pring HIP logging information, the function is defined as
```cpp
#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)
```
So in HIP code, call `ClPrint()` function with proper input varibles as needed,
for example,
```cpp
ClPrint(amd::LOG_INFO, amd::LOG_INIT, "Initializing HSA stack.");
```
## HIP Logging Example:
Below is an example to enable HIP logging and get logging information during execution of hipinfo on Linux,
```console
user@user-test:~/hip/bin$ export AMD_LOG_LEVEL=4
user@user-test:~/hip/bin$ ./hipinfo

On Windows, AMD_LOG_LEVEL can be set via environment variable from advanced system setting, or from Command prompt run as administrator, as shown below as an example, which shows some debug log information calling backend runtime on Windows.
```
C:\hip\bin>set AMD_LOG_LEVEL=4

## HIP Logging Tips:
- HIP logging works for both release and debug version of HIP application.
- Logging function with different logging level can be called in the code as
needed.
- Information with logging level less than AMD_LOG_LEVEL will be printed.
- If need to save the HIP logging output information in a file, just define the
file at the command when run the application at the terminal, for example,
```console
user@user-test:~/hip/bin$ ./hipinfo > ~/hip_log.txt
```
