So, to summarize how the patch changes the under-the-hood kernel launch machinery: - device-side is unchanged. Kernel function is generated with the real kernel name - host-side stub is still generated with the `__device_stub` prefix. - host-side generates a 'handle' variable with the kernel function name, which is a pointer to the stub. - host-side registers the `handle variable` -> `device-side kernel name` association with the HIP runtime. - the address of the handle variable is used everywhere where we need a kernel pointer on the host side. I.e. passing kernel pointers around, referring to kernels across TUs, etc. - `<<<>>>` becomes an indirect call to a `__device_stub` function using the pointer retrieved from the handle.
