## Summary of Changes Hello @srkreddy1238, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly expands TVM's capabilities by integrating a Vulkan backend for Adreno GPUs, aiming to match OpenCL's performance. It introduces a more robust and flexible memory management system that differentiates between buffer and image resources, and refines data transfer operations. The changes also include a new Vulkan-native timer for precise performance measurement and a unified approach to handling OpenCL and Vulkan within the build system and testing framework. ### Highlights * **Vulkan Backend for Adreno GPU**: Enabled Vulkan backend support for Adreno GPUs, allowing them to be used with Vulkan for performance comparable to OpenCL. This lays the groundwork for future Vulkan-specific extensions like co-op matmul. * **Unified Pipeline and GTest Configuration**: The Relax and TIR pipelines now use a common approach for both OpenCL and Vulkan backends. GTest configuration has been centralized and refactored to support both OpenCL and Vulkan tests more efficiently. * **Enhanced Vulkan Memory Management**: Introduced new abstractions for Vulkan resources (buffers and images) and memory management, including support for different memory scopes (e.g., textures) and improved data transfer mechanisms between CPU and GPU, and between different Vulkan resource types. * **Vulkan Device Timer for Profiling**: Implemented a Vulkan-native device timer, replacing the previous chronos-based approach, to provide more accurate profiling information for GPU operations. * **SPIR-V Code Generation for Images**: Updated the SPIR-V code generator to support image arguments and operations (texture2d_store, texture2d_load), enabling the use of image textures in Vulkan kernels. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback.
