| |
Hi Greg and Olof, I wanted to let you know that I put the sources of our new userspace thunk library in GitHub, as we discussed a few weeks ago during the review of the driver. The link is: https://github.com/HabanaAI/hl-thunk
As this library was written from scratch in the past month, it is still quite small and provides only the minimal functionality over the IOCTLs. We did ported some of the userspace tests we have in our runtime to this library (using CMocka framework) to demonstrate how to use the IOCTLs. The library is written in pure C. It is a stateless library (at least for now) and I took the basic design from drm library.
Going forward, we plan to (in order of importance): 1. Integrate this in our S/W stack. In effect, remove the functionally we expose in the thunk layer from the runtime and make the runtime link with the thunk layer and call it instead of calling directly to the IOCTLs. This will be done in the next week or two. 2. Add additional tests for Goya and for future ASICs. We plan to use this library for doing bring-ups on Palladium and the real ASICs as it provides us with easy platform for testing purposes. 3. Add more functionality to the library. I didn't yet decided how much functionality I want to add to this layer though, because I want to keep it thin.
Bottom line, this is definitely not some mockup library. This will be an integral part of our S/W stack going forward.
I sincerely hope we can open source additional S/W parts in the future. I'll try pushing to this goal as much as I can inside the company.
Thanks, Oded
