Cooperation on ISA extension emulation?
Good evening!
The objectives of opensbi-h and my newly published experimental fork opensbi-isa-ext-emu, that mainly seeks to close the gap between existing hardware implementations and RVA22/RVB23/RVA23, appear to be quite similar and compatible.
Do you see room for future cooperation?
Hello, currently there is no plan to keep opensbi-h up to date due to its impracticality and lack of demand. However, if you wish to use the code I'm happy to help.
In that case I will probably prioritize Zvbb, the otherwise only remaining gap between the Spacemit X60 cores and RVA23, and cache management functionality for pre-RVA22 chips like the JH7110. Thanks, nevertheless.
