Great feature, thanks! This will take some time to review and test - so bear with us, but with some back and forth we'll see where we land. |
Kernels are generated as SYCL free functions and compiled at runtime through the oneAPI kernel compiler. The Jinja templates are shared with CUDA and HIP via templates/sycl_compat.cuh; the backend is now a string rather than an is_hip boolean, and JITKernel::execute also takes argument sizes.
Mirrors the CUDA job. GitHub offers no Intel GPU runner, so only the build is exercised.
The stable-ABI headers the extension includes are not all present before 2.10, which the precompiled-extension check in extlib has required all along. The SYCL guard now enforces the same floor.
Upstream PASSIONLab#217 replaced HIP's __threadfence_block() with the amdgcn wave barrier, so no template emits the token any more.
