May 1, 2026May 2026 monthly summary for google/dive. Delivered a set of build-system and quality improvements that directly reduce build/deploy friction, improve reliability, and enable cross-platform workflows. Key features include a CMake-driven deployment header and a dedicated RenderDoc library, flexible host build generator selection, and unified compiler warnings across modules. These changes enhance deployment correctness, developer productivity, and CI resilience, while laying groundwork for future multi-config and cross-module improvements. Key context: - Repository: google/dive - Month: 2026-05 - Highlights: 1) CMake Build System Refactor and RenderDoc Library - Introduced mechanism to generate a C++ header with the deployment folder path from CMake and ensured the value is shared with the layer config JSON. - Updated device_resources_constants.h to be generated with DIVE_DEPLOY_FOLDER_PATH and linked files that include this header to a new library to improve dependency management. - Made remote_files.h an actual library under src/dive/utils called renderdoc_files to simplify dependencies. - Commits: 14403c693510194c8f1b282454770cc71c8b7d6a 2) Flexible Build Generator Selection - Added a command-line option to specify a custom CMake generator for host builds (e.g., Ninja), increasing build flexibility especially on Windows. - Commits: be9381e5aa527d1286be6cf9c15df949bca3c0fa 3) Unified Compiler Warnings Across Modules - Enabled comprehensive compiler warnings across the codebase to catch issues early and improve code quality. - Early work focused in the ui folder with -Wall and -Werror; extended to more targets and modules using a common warning function. - Commits: 978f3557f3dc25581c7a0caf363bb7aff8990471, 6782841a5f23bee4f3fb56253abc0e19b283b574 Major bugs fixed: - Reduced build and deployment errors caused by missing or mislinked generated headers by introducing a dedicated renderdoc_files library and ensuring header generation consistently references DIVE_DEPLOY_FOLDER_PATH. - Improved cross-module dependency consistency by centralizing warning configurations, preventing silent issues related to shadowing and undiscovered warnings in new code paths. Overall impact and accomplishments: - Improved deployment reliability and consistency across layers by correctly propagating deployment paths into generated headers and config JSON. - Increased build flexibility and developer productivity with configurable host CMake generators. - Elevated code quality and maintainability through unified and enforceable compiler warnings across modules, leading to earlier detection of issues. - Strengthened vendor- and CI- readiness for cross-platform builds and future multi-config support. Technologies/skills demonstrated: - CMake scripting and generation for header values and build-time constants - Dependency management and library structuring to simplify builds (renderdoc_files library) - Build tooling and cross-platform workflows (Ninja, Windows builds) - Static analysis discipline (compiler warnings, -Wall/-Werror) and cross-module consistency - Collaboration readiness for multi-config and cross-branch changes

Apr 1, 2026April 2026 performance snapshot for google/dive focused on expanding capture coverage, stabilizing tooling, and reducing maintenance risk. Key GFXR frame-boundary enhancements and configurable capture end-points broaden applicability and improve accuracy. Desktop replay/testability gains were achieved via gfxr_ext_decode_lib integration and a targeted clang-tidy pass. Stability improvements were driven by initialization hygiene, PM4 capture lifecycle fixes, Vulkan cleanup, and an SELinux workaround to keep captures flowing in enforcing mode. Tooling and packaging were upgraded (NDK r29, Dive 1.2.0, libwrap build/packaging) to reduce technical debt and streamline deployment.

Feb 1, 2026February 2026: Implemented key client-usability and stability improvements across the Dive/GFXR stack. Delivered public dependency declarations in dive_status CMake to ensure transitive dependencies reach client targets, reducing undefined references and simplifying integration. Reintroduced the gfxr replay validation layer to guarantee required libraries are deployed, preventing runtime failures. Expanded test coverage with GfxrCaptureData unit tests for loading and validation, increasing confidence in capture integrity. Added an automation script to merge GFXR submodule configurations into the main .gitmodules, streamlining subtree pulls and consistent submodule checkout. Implemented Vulkan replay stability and compatibility enhancements, including proper destruction of query pools, renderpass2 support, host query pool enablement, and safer memory handling, complemented by warnings-as-errors to catch issues early. These efforts collectively improved reliability, developer productivity, and business value by reducing integration friction and preventing runtime failures.

Sep 1, 2025September 2025 (google/dive): Delivered key reliability and performance improvements across tracing, build, and profiling tooling. Stabilized trace collection and replay synchronization in libwrap, enabling correct frame capture and reliable downstream tooling signals. Implemented deterministic PM4 frame capture and refined trace file handling with truncation and explicit replay finish signaling. CI and tooling improvements reduced pipeline noise and improved visibility: plain Gradle output in CI, Dive UI logging to console, and removal of unused submodule. Profiling plugin is now executable post-deploy, enabling reliable profiling. Android build scope tightened to replay and layer, speeding up builds. These changes yield faster iteration, easier issue diagnosis, and more robust cross-platform performance.
