Add bundled IO support to portable executor runner #15368

mansnils · 2025-10-23T11:07:02Z

Executor runner supports both models with/wo bundled io in same path.
To enable bundled IO EXECUTORCH_BUILD_DEVTOOLS and
EXECUTORCH_ENABLE_BUNDLE_IO are required.

Adds tests in Arm backend for testing this/depending on this.
Except for enabling bundle-io for VGF backend where applicable,
some additional resnets model tests are enabled as well.

Avoids narrowing conversion errors in pte_to_header script by switching
char to unsigned char.

Need to either add DEVTOOLS=ON to all cmake recipes that builds the executor runner or use an optional build flag.

This file gets copy pasted a ton as a basic example of a runner. Im pretty resistant to something like this which will tempt people to use it it as a tester. Im already not a huge fan of having the benchmarking stuff in here.

This is now an optional build flag.

just use gflags to pass these as an arg

-  std::stringstream list_of_input_files(FLAGS_inputs);

are .ptd and bundledProgram mutually exclusive? @lucylq @Gasoonjia.

ptd is only used to pass weights along its not another way to pass inputs to this file afaik

@mansnils Do you have strong preference to not fork the runner?

We currently have a slight preference in this case to have you fork it rather then add the ifdef stuff. But if you feel really strongly not too we would hear you out.

Yes we really prefer not to fork the runner.

we're integrated with the Vulkan flows too, so running vulkan or VGF (vulkan extension features) delegates in the same runner and same system configs, sometimes just with a vulkan layer driver, is much preferred.
