Add rocprofiler_tool_configure_result_experimental_t with tool_reattach/tool_detach callbacks - Add rocprofiler_call_client_reattach and rocprofiler_call_client_detach C exports - Implement reattachment tracking in rocprofiler_register_attach to differentiate initial attachment from reattachment cycles - Add rocprofiler_register_invoke_reattach for handling reattachment requests **Design Changes - Registration System Flow:** The registration system now supports a dual-path initialization: 1. Initial Attachment Flow: - rocprofiler_register_attach() -> rocprofiler_register_invoke_all_registrations() - Full tool initialization with complete context setup - Sets prev_attached atomic flag to track state 2. Reattachment Flow: - rocprofiler_register_attach() detects prev_attached=true -> rocprofiler_register_invoke_reattach() - Bypasses full re-initialization, calls client reattach callbacks instead - Preserves existing contexts and buffers, only reactivates profiling services **Design Changes - Tool Library Loading:** Enhanced rocprofiler-register library loading with function pointer resolution: - Extended rocp_set_api_table_data_t tuple to include reattach/detach function pointers - Automatic symbol resolution for rocprofiler_call_client_reattach/detach functions - Support for both LD_PRELOAD and dlopen scenarios with consistent callback availability **Design Changes - Context Management:** Introduced dual context systems for attachment scenarios: - get_contexts() - Original contexts for standard tool initialization - get_attach_contexts() - Separate context map for attachment-specific lifecycle - attach_init() - Creates contexts for ALL buffer tracing services using existing buffers - attach_start() - Selectively starts contexts based on configuration options - attach_detach() - Cleanly stops and destroys attachment contexts **Design Changes - Buffer Management:** Added reset_tmp_file_buffer() template for clean reattachment state: - Properly closes and removes old temporary files - Deletes existing file_buffer instances to prevent stale file position tracking - Creates fresh file_buffer instances for clean reattachment cycles - Addresses core issue where file position metadata becomes stale between cycles **Design Changes - Environment Variable Injection:** Added ROCP_REGISTERED_TOOL_ATTACH environment variable: - Distinguishes attachment-loaded tools from LD_PRELOAD scenarios - Enables registration system to apply attachment-specific logic - Helps tools adapt behavior for attachment vs standard initialization **Attachment Context Management:** - Add attach_init/attach_start/attach_detach functions for dynamic context lifecycle - Add reset_tmp_file_buffer template for clean reattachment state management - Implement get_attach_contexts() for tracking active attachment contexts **Test Infrastructure:** - Add projects/rocprofiler-sdk/tests/rocprofv3/reattach/ comprehensive test suite - Include reattachment test scripts with unified attachment/detachment cycles - Add validate.py with trace data validation for kernel, memory copy, HSA API, and agent info - Add conftest.py for JSON and CSV data loading utilities **Configuration Updates:** - Update CMakeLists.txt to include reattachment tests in build system - Add environment variable ROCP_REGISTERED_TOOL_ATTACH for attachment state tracking - Enhance rocprofiler-register library loading with reattach/detach function resolution **Flow Impact Analysis:** This design enables robust multi-cycle attachment by: 1. Preventing duplicate initialization on reattachment 2. Maintaining separate context lifecycles for attachment vs standard operation 3. Ensuring clean temporary file state between attachment cycles 4. Providing tools with explicit reattach/detach callback hooks 5. Supporting both programmatic and environment-based tool configuration The experimental nature allows for iteration on the API while establishing the foundation for production-ready dynamic profiling capabilities. * Fix misc clang-tidy warnings/errors * CMake Option and Environment Variable Updates - CMake: ROCPROFILER_REGISTER_ALWAYS_SUPPORT_ATTACH -> ROCPROFILER_REGISTER_BUILD_DEFAULT_ATTACHMENT - Env: ROCPROFILER_REGISTER_ATTACHMENT_ENABLED -> * Source reorganization * Formatting + new lines at EOF * Fix flake8 F841: local variable is assigned to but never used * Update attachment test - get rid of 5 second start delay - add roctx * Rework implementation - Remove rocprofiler_tool_configure_result_experimental_t in lieu of rocprofiler_configure_attach - Add <rocprofiler-sdk/experimental/registration.h> - TODO: Update process_attachment.rst * Handle re-attachment options - inherit options from previous attachment - check previous options do not modify data collection services * Fix support for tools w/o rocprofiler_configure_attach - fix segfault when rocprofiler_configure_attach does not exist - fix naming convention for functions accepting attach dispatch table - cleanup rocprofiler_configure_attach implementation in rocprofv3 tool * attach: remove unknown agent handling - Change was from earlier commit, no longer needed * attach: add error for attaching without library loaded * attach: revise version numbering * attach: register header revisions * attach: clang format register * attach: formatting * attach: fix build failure - Remove cross dependency into rocprofiler-sdk, fixes build on some systems * attach: revise register library detection * Update rocprofiler-register and attach library - formatting - proper signature of register_functor for rocprofiler-sdk-attach library callback - remove get_dispatch_registration_table() * Bump rocprofiler-register version to 0.6.0 + AnyNewerVersion * Fix output support for rocprofiler-sdk-tool * Fix formatting * Fix clang tidy errors * Misc rocprofiler-sdk-attach fixes * attach: add sigint handling to attach python * tool README.md formatting Co-authored-by: Jonathan R.

[rocprofv3] signal handler fix (#332)
* rocprofv3: LD_PRELOAD for signal and sigaction

KiB)

- use GitHub URL as this is more accessible
* Update ring_buffer<Tp>
- account for alignment padding
* Update buffered_output
- track number of bytes stored
- add nullptr checks

* Update config.hpp
- add option to enable/disable signal handlers
- add option for minimum_output_bytes

rocprofv3: refactor and reorganize rocprofiler-sdk-tool library (#1138)
* Add rocprofv3-multi-node.md to source/lib/rocprofiler-sdk-tool
* Initial source re-organization
- create "output" static library
* Update include/rocprofiler-sdk/cxx/serialization.hpp
- add GPR count fields to kernel symbol serialization
* Add source/scripts/generate-rocpd.py
- reads one or more JSON output files from rocprofv3 and writes rocpd SQLite3 database
- Note: preliminary implementation
* More reorganization b/t lib/rocprofiler-sdk-tool and lib/output
* Updates to generate-rocpd.py
- add SQL views
- option: --absolute-timestamps -> --normalize-timestamps
- option: --generic-markers
- misc fixes with regards to getting the views working
- support marker names
* Update generate-rocpd.py
- Add --marker-mode option
* Update generate-rocpd.py
- Improve debugging of bad bulk SQLite statements
* Update rocprofv3-multi-node.md
- cleanup of proposed SQL schema
* lib/output/format_path.{hpp,cpp}
- rename format to format_path (in config.hpp and config.cpp)
- move format_path functionality to format_path.{hpp,cpp}
* Rework lib/output/tmp_file_buffer.{hpp,cpp}
* Update output_key.cpp
- support %cwd%, %launch_date%
* Rework lib/output/buffered_output.hpp
* Support csv_output_file constructed via domain_type
* Update lib/output/domain_type.{hpp,cpp}
- get_domain_trace_file_name
- get_domain_stats_file_name
* Update lib/rocprofiler-sdk-tool/tool.cpp
- tweak headers
* Update lib/output/generate*.cpp
- remove include of helpers.hpp
- CSV uses domain_type for filenames
* Update samples/counter_collection/per_dev_serialization.cpp
- make wait_on volatile
* Remove tool_table from lib/output and lib/rocprofiler-sdk-tool
- Also split various structs into their own files
- lib/output/agent_info
- lib/output/metadata
- lib/output/kernel_symbol_info
- lib/output/counter_info
- Implemented rocprofiler::tool::metadata
* Optimize rocprofiler_tool_counter_collection_record_t
- reduce the size of the struct from 24784 bytes to 8376 bytes
* Introduced output_config
- split subset of config (from tools library) into output_config to be able to configure the output generating functions separately from the tool library
- this is a significant step towards the output generating functions not relying on static global memory
* Stream chunks of data into output instead of loading all info memory
* Remove duplicate group_segment_size in rocprofiler_kernel_dispatch_info_t serialization
* Adding Q&A to rocprofv3-multi-node.md
