Forgot to add dri-devel.

Hi Greg,
Following our conversations a couple of months ago, I'm happy to tell you that Habanalabs has open-sourced its TPC (Tensor Processing Core) LLVM compiler, which is a fork of the LLVM open-source project.
The project can be found on Habanalabs GitHub website at: https://github.com/HabanaAI/tpc_llvm
There is a companion guide on how to write TPC kernels at: https://docs.habana.ai/en/latest/TPC_User_Guide/TPC_User_Guide.html
That's great news, thanks for pushing for this and releasing it all!
Yeah this is neat.
There's still the problem that we spent the past 2.5 years pissing off a lot of people for an imo questionable political project, bypassing all the technical review and expertise. Now that the political nonsense is resolved I think we need to look at at least the technical cleanup. The angered people are much harder to fix, so let's maybe ignore that (or perhaps a ks topic, no idea, I'm honestly not super motivated to rehash this entire story again). Here's what I think we should do:
- move drivers/misc/habanalabs under drivers/gpu/habanalabs and
review/discussions on dri-devel
- grandfather the entire current situation in as-is, it's not the only
driver we have with a funny uapi of its own (but the other driver did manage to get their compiler into upstream llvm even, and not like 2 years late)
- review the dma-buf stuff on dri-devel and then land it through
standard flows, not the gregk-misc bypass
- close drivers/misc backdoor for further accel driver submissions,
I'd like to focus on technical stuff in this area going forward and not pointless exercises in bypassing due process and all that
I expect we'll have a proper discussion what the stack should look like with the next submission (from a different vendor maybe), that ship kinda sailed with habanalabs.
Cheers, Daniel
