I know about no such platform I'm afraid. QEMU does not have the R2k/R3k exception/MMU/cache model and implementing that would be a considerable effort I see no volunteers for. I haven't heard of any other simulator which might be closer to implementing that model. As to using real hardware -- I might be the closest myself to be capable of doing some automated testing as I have an R3k machine in my home lab wired for remote control. It could track Ralf's `mips-for-linux-next' branch and watch out for regressions, by trying to build and boot kernels automatically on a regular basis; maybe doing some further validation even, such as running GCC or glibc regression testing. But while the target is ready I'm still missing the host-side setup, which I haven't completed. I don't think there's any other hardware readily available which could be hooked somewhere. So for the time being I think we need to continue relying on people spotting issues by hand. I think we've been doing pretty good overall. Thanks for your review. Maciej
