Hi Christoffer! I've been hacking on your mmio test code, still ongoing, but here's a glance of what I have. I'm working on some tests for Antonios's VFP stuff at the moment. https://git.kernel.org/?p=linux/kernel/git/rusty/linux-kvm-arm.git;a=shortlog;h=refs/heads/test-code BTW, what's the status of mmio decode, particularly thumb? Cheers, Rusty.
