The project has been talking to the RISC-V Foundation for a while about this. The tricky part is that adding official support for a new architecture isn't a cheap or easy undertaking for the project. The autobuilder for example has hardware to pay for as well as bandwidth and power costs. If we add a new architecture, the test matrix is larger and the costs rise. There is also the increased human load of more tests, more failures and more work to do. Intel, AMD and ARM are platinum members and this partly allows for the architecture support. MIPS and PowerPC are on the list for legacy reasons and their testing scope is being scaled back. We've discussed and agreed that adding a new architecture with all the work it entails is at least around a platinum membership level of impact for us. Therefore, to have official support of a new architecture, we've asked that there be support either from existing membership or new members of around that level. When you look at the details of what you get, that price tag is actually quite reasonable for the level of automated testing performed. We've been clear about our position on this for a while. There are actually discussions in progress about it with both the foundation and RISE and I have some reasons to be optimistic but some of this has been going back and forth for a number of years. FWIW, personally I would love to see the support officially there and it in our test matrix. Cheers, Richard
