Following up on their tweet earlier this week that they would be working to open-source more of their GPU software stack and hardware documentation, AMD now says they will be releasing documentation followed by the source code for their Micro-Engine Scheduler (MES) IP block found within Radeon GPUs.
AMD posted to Twitter/X this evening a follow-up to their original docs/open-source statement:
"We are working to release Micro-Engine Scheduler(MES) documentation towards end of May and will follow up with published source code for external review and feedback. We have also opened a GitHub tracker, which will have the latest status on fixes and release dates."
The Micro-Engine Scheduler firmware is what was specifically called out previously by Tiny Corp after voicing frustration over MES issues and calling for that firmware at least to be open-sourced.
AMD now seems to be working toward at least getting out MES hardware documentation followed by source code once MES goes through the necessary legal/external code review processes. Given the hardware documentation drama over the years, that code review process for open-sourcing can unfortunately take some time and in some cases lead to the code not being published. Hopefully the documentation and/or source code will lead to more bugs being addressed.
Today's statements also do not cover the multitude of other hardware blocks comprising modern AMD Radeon GPUs.
