In a future change, most of the allocation tracking will be removed from liboffload itself and be delegated to the plugins. Therefore, we will need to know which plugin is in charge of the allocation.

@leandrolcampos I've needed to touch a lot of the conformance tests here, but for some reason I'm unable to coerce it into being built and tested.
Can you have a look and let me know if all of this looks okay?

Hi @RossBrunton,
I'll take a look until the end of the day.
There was a problem hiding this comment.
@RossBrunton, could you take a look at this #157773? Merging this patch will ensure the conformance tests run correctly.
I also prepared a Gist containing a step-by-step guide to setting up an environment to build and run the conformance tests on Windows Subsystem for Linux (WSL 2) with NVIDIA GPUs. I think it can be easily adapted to different OS and/or platform configurations.
Finally, thanks for your care with the conformance tests! If you're interested in the broader context of this work, I recently wrote about it in this post on the LLVM Blog.

There was a problem hiding this comment.
This looks good to me, but one problem I've noticed in the interface that a single plugin can only expose a single platform. This is not true in general. For example, in level-zero, there can be multiple separate drivers in the OS, handling different devices. These need to be separate platforms.

In a future change, most of the allocation tracking will be removed from
liboffload itself and be delegated to the plugins. Therefore, we will
need to know which plugin is in charge of the allocation.
