## Motivation PR #4797 added CK Tile bwd weight kernels to the CK Profiler. The two-stage kernels were not supported in the initial PR. This PR adds the the missing bwd weight two-stage kernels to the CK Profiler. ## Technical Details Extended the CK Tile conv builder factory to build also the elementwise ops required for the two-stage kernels. Extended the CK Builder for CK Tile instance to accept the two-stage flag as part of the algorithm configuration. ## Test Plan Added units tests for CK Builder that verify the two-stage kernel construction. ## Test Result If CI passes, the added unit tests are passing. ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests. --------- Co-authored-by: Ville Pietilä <>
