* Disable c++20-compat warnings when building old CK in C++20 mode Turns out that this creates some warnings for no good reason. * ck-builder: add missing layouts and element-wise op names For layouts, we can directly use the ::name attribute, which should cover all layouts. For element-wise ops, I just added the ones which are currently missing when compiling CK with -DMIOPEN_REQ_LIBS_ONLY.
Builder
This directory contains the experimental builder feature for composable_kernel.
- Status: In development (October - November 2025)
Overview
The builder provides a high-level, semantically-clear interface for constructing composable kernel operations, with an initial focus on convolution kernels for MIOpen. It leverages modern C++20 features (such as POD structs as non-type template parameters, concepts, and designated initializers) to simplify kernel instantiation and improve developer experience.
This project is a prototype for a more general builder pattern for all of composable_kernel (CK) and CKTile, but is currently limited to formalizing the interface between MIOpen and CK.

CMake Configuration
To enable the experimental builder, configure your build with:

Building and testing
During development, build and test from the CK build directory with
ninja test_conv_builder && bin/test_conv_builder
