It's definitely not in the kernel source, unless you qualify the help text of CONFIG_GOLDFISH as such: Enable support for the Goldfish virtual platform used primarily for Android development. Unless you are building for the Android Goldfish emulator say N here. which does not help for randconfig and other builds and does not prevent users from enabling it accidentaly. That all wouldn't be as bad if at least the minimal provisioning of damage prevention would have been done. > Unfortunately the people who did the emulator didn't feel the urge to > provide a way to detect the platform was Goldfish. Sure, and the people shoving it into the kernel didn't feel the urge to enforce that. > Historically it also used its own custom device discovery scheme.
