Hi Zach It takes a _long_ while to get to raw serial console login prompt of a stripped-down ubuntu nano image. On my core i7 (first gen) the simulator can sometimes reach around 1M instructions per second but is usually slower. On top of that I don't know if it has any kind of support for graphic

HI. I'm building a LAVA service for running fast models. Quite soon (*) we'll be ready to open an alpha access. Right now you will need to bring your own root filesystem and kernel image to use it. With that in mind I wanted to start a discussion about the state of A15 support in Linaro kernel(s).
