Some details, this is running a Gentoo arm system, cross-compiled using a qemu-user chroot environment. Yes, that's right, Gentoo, running on a Tesla. All those USE flags, CFLAGS, and optimizations are going to add speed to my car. My 5 second 0-60 will be faster than your 5 second 0-60!
There was probably at least 5 days of continuous compilation going on here. The system is almost completely independent. "OMG did you seriously flash the Tegra?" No, I didn't go that far. I'm running Gentoo in a chroot environment within the Tesla OS itself. I will definitely be making a post later diving into the technical details of it.
