Full documentation for ROCprofiler-SDK is available at [rocm.docs.amd.com/projects/rocprofiler-sdk](https://rocm.docs.amd.com/projects/rocprofiler-sdk/en/latest/index.html)
-`--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.
- 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.
- Fixed missing callbacks around internal thread creation within counter collection service.
- Fixed potential data race in the ROCprofiler-SDK double buffering scheme.
- Fixed usage of std::regex in the core ROCprofiler-SDK library that caused segfaults or exceptions when used under dual ABI.
- Fixed Perfetto counter collection by introducing accumulation per dispatch.
- Fixed code object disassembly for missing function inlining information.
- Fixed queue preemption error and `HSA_STATUS_ERROR_INVALID_PACKET_FORMAT` error for stochastic PC-sampling in MI300X, leading to stabler runs.
- Fixed the system hang issue for host-trap PC-sampling on MI300X.
- Fixed `rocpd` counter collection issue when counter collection alone is enabled. `rocpd_kernel_dispatch` table is updated to be populated by counters data instead of kernel_dispatch data.
- Fixed `rocprofiler_*_id_t` structs for inconsistency related to a "null" handle:
- The correct definition for a null handle is `.handle = 0` while some definitions previously used `UINT64_MAX`.
- Fixed kernel trace csv output generated by `rocpd`.
- Dynamic process attachment- ROCprofiler-sdk and `rocprofv3` now facilitate dynamic profiling of a running GPU applications by attaching to its process ID (PID), rather than launching the application through the profiler itself.
- Scratch-memory trace information to the Perfetto output in `rocprofv3`.
- New capabilities to the thread trace support in `rocprofv3`, including real-time clock support for thread trace alignment on gfx9 architecture. This enables high-resolution clock computation and better synchronization across shader engines. Additionally, `MultiKernelDispatch` thread trace support is now available across all ASICs.
- Improved process attachment and updated the corresponding [documentation](https://rocm.docs.amd.com/projects/rocprofiler-sdk/en/latest/how-to/using-rocprofv3-process-attachment.html).
- Improved [Quick reference guide for rocprofv3] (https://rocm.docs.amd.com/projects/rocprofiler-sdk/en/latest/quick_guide.html).
- Updated installation documentation with links to the latest repository (https://rocm.docs.amd.com/projects/rocprofiler-sdk/en/latest/install/installation.html).
