Kernel Name Information Type.

Function Documentation

◆ rocprofiler_query_kernel_info()

ROCPROFILER_API rocprofiler_status_t rocprofiler_query_kernel_info ( rocprofiler_kernel_info_kind_t  kind,
rocprofiler_kernel_id_t  kernel_id,
const char **  data 
)

Query Kernel Information Data using an allocated data pointer by the user, user can get the size of the data using rocprofiler_query_kernel_info_size, the user can get the data using rocprofiler_kernel_id_t and the user need to identify one type of information available in ::rocprofiler_kernel_info_t.

Parameters
[in]kindInformation kind requested by the user
[in]kernel_idKernel ID
[out]dataInformation Data
Return values
ROCPROFILER_STATUS_SUCCESS,ifthe information was found
ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,ifrocprofiler_initialize wasn't called before or if rocprofiler_finalize is called
ROCPROFILER_STATUS_ERROR_KERNEL_NOT_FOUND
if the kernel was not found in the saved kernels
ROCPROFILER_STATUS_ERROR_KERNEL_INFORMATION_MISSING
if the kernel was found in the saved kernels but the required information is missing

◆ rocprofiler_query_kernel_info_size()

ROCPROFILER_API rocprofiler_status_t rocprofiler_query_kernel_info_size ( rocprofiler_kernel_info_kind_t  kind,
rocprofiler_kernel_id_t  kernel_id,
size_t *  data_size 
)

Query Kernel Information Data size to allow the user to allocate the right size for the information data requested, the information will be collected using rocprofiler_kernel_id_t by using rocprofiler_query_kernel_info and the user need to identify one type of information available in ::rocprofiler_kernel_info_t.

Parameters
[in]kernel_info_typeThe tyoe of information needed
[in]kernel_idKernel ID
[out]data_sizeKernel Information Data size
Return values
ROCPROFILER_STATUS_SUCCESS,ifthe information was found
ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,ifrocprofiler_initialize wasn't called before or if rocprofiler_finalize is called
ROCPROFILER_STATUS_ERROR_KERNEL_NOT_FOUND
if the kernel was not found in the saved kernels
ROCPROFILER_STATUS_ERROR_KERNEL_INFORMATION_MISSING
if the kernel was found in the saved counters but the required information is missing
