ROCprofiler-SDK for AFAR IV

Added

API:

ROCprofiler-SDK for AFAR V

Added

API:

• Agent or device counter collection
• PC sampling (beta)

Tool:

• Single JSON output format support
• Perfetto output format support (.pftrace)
• Input YAML support for counter collection
• Input JSON support for counter collection
• Application replay in counter collection
• rocprofv3 multi-GPU support:
  • Multiprocess (multiple files)

Changed

• rocprofv3 tool now requires mentioning -- before the application. For detailed use, see Using rocprofv3

Resolved issues

• Fixed SQ_ACCUM_PREV and SQ_ACCUM_PREV_HIRE overwriting issue

ROCprofiler-SDK 0.4.0 for ROCm release 6.2 (AFAR VI)

Added

• OTF2 tool support
• Kernel and range filtering
• Counter collection definitions in YAML
• Documentation updates (SQ block, counter collection, tracing, tool usage)
• rocprofv3 option --kernel-rename
• rocprofv3 options for Perfetto settings (buffer size and so on)
• CSV columns for kernel trace
  • Thread_Id
  • Dispatch_Id
• CSV column for counter collection

ROCprofiler-SDK 0.5.0 for ROCm release 6.3 (AFAR VII)

Added

• Start and end timestamp columns to the counter collection csv output
• Check to force tools to initialize context id with zero
• Support to specify hardware counters for collection using rocprofv3 as rocprofv3 --pmc [COUNTER [COUNTER ...]]
• Memory Allocation Tracing

Changed

• --marker-trace option for rocprofv3 now supports the legacy ROCTx library libroctx64.so when the application is linked against the new library librocprofiler-sdk-roctx.so.
• Replaced deprecated hipHostMalloc and hipHostFree functions with hipExtHostAlloc and hipFreeHost for ROCm versions starting 6.3.
• Updated rocprofv3 --help options.
• Changed naming of "agent profiling" to a more descriptive "device counting service". To convert existing tool or user code to the new name, use the following sed: find . -type f -exec sed -i 's/rocprofiler_agent_profile_callback_t/rocprofiler_device_counting_service_callback_t/g; s/rocprofiler_configure_agent_profile_counting_service/rocprofiler_configure_device_counting_service/g; s/agent_profile.h/device_counting_service.h/g; s/rocprofiler_sample_agent_profile_counting_service/rocprofiler_sample_device_counting_service/g' {} +
• Changed naming of "dispatch profiling service" to a more descriptive "dispatch counting service". To convert existing tool or user code to the new names, the following sed can be used: -type f -exec sed -i -e 's/dispatch_profile_counting_service/dispatch_counting_service/g' -e 's/dispatch_profile.h/dispatch_counting_service.h/g' -e 's/rocprofiler_profile_counting_dispatch_callback_t/rocprofiler_dispatch_counting_service_callback_t/g' -e 's/rocprofiler_profile_counting_dispatch_data_t/rocprofiler_dispatch_counting_service_data_t/g' -e 's/rocprofiler_profile_counting_dispatch_record_t/rocprofiler_dispatch_counting_service_record_t/g' {} +
• FETCH_SIZE metric on gfx94x now uses TCC_BUBBLE for 128B reads.
• PMC dispatch-based counter collection serialization is now per-device instead of being global across all devices.

Resolved issues

• Create subdirectory when rocprofv3 --output-file includes a folder path
• Fixed misaligned stores (undefined behavior) for buffer records
• Fixed crash when only scratch reporting is enabled
• Fixed MeanOccupancy metrics
• Fixed aborted-application validation test to properly check for hipExtHostAlloc command
• Fixed implicit reduction of SQ and GRBM metrics
• Fixed support for derived counters in reduce operation
• Bug fixed in max-in-reduce operation
• Introduced fix to handle a range of values for select() dimension in expressions parser
• Conditional aql::set_profiler_active_on_queue only when counter collection is registered (resolves Navi3 kernel tracing issues)

Removed

• Removed gfx8 metric definitions
• Removed rocprofv3 installation to sbin directory

ROCprofiler-SDK 0.5.0 for ROCm release 6.4
