Lunderberg opened a new pull request, #16542: URL: https://github.com/apache/tvm/pull/16542
Prior to this commit, calls from Relax to external PackedFuncs could only be done through the TVM global registry. While Relax functions accepting a callback could be written as `callback_arg: R.Callable(arg_struct_info, ret_struct_info)`, attempting to compile these functions would raise an error during the `CodeGenVM` step of `relax.build`. In addition, the global registry is only queried when initializing the `relax.VirtualMachine`, and so later changes requires restarting the VM. This commit updates both the `CodeGenVM` lowering pass and the relax VM to support callbacks. The motivating use case is with the `LazyTransformParams` pass, to improve flexibility by avoiding use of the global registry. -- This is an automated message from the Apache Git Service.
