I just sent this to tech-chairs, but due to the nature of your work Stephano suggested getting feedback here as well.

The Configuration Structure task group has been working on how software can determine the capabilities/configuration of the hardware it is running on. At long last we have something that is ready for wider review. (Few people spend time in tech-config regularly, so just a few people have really read this spec so far. There might still be some glaring holes.)

Please take some time to read and review https://github.com/riscv/configuration-structure/blob/master/riscv-configuration-structure-draft.adoc (3200 words). I'm looking forward to your feedback so we can make the spec better, and hopefully freeze it in a few weeks.

Thank you,
Tim
