From f349474920d80838ecea3d421531fdb0660b8740 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 23 Jan 2019 14:56:17 +0800 Subject: minikconfig: implement allnoconfig and defconfig modes Apart from defconfig (which is a no-op), allyesconfig/allnoconfig/randcondfig can be implemented simply by ignoring the RHS of assignments and "default" statements. The RHS is replaced respectively by "true", "false" or a random value. However, allyesconfig and randconfig do not quite work, because all the files for hw/ARCH/Kconfig are sourced and therefore you could end up enabling some ARM boards in x86 or things like that. This is left for future work, but I am leaving it in to help debugging minikconf itself. allnoconfig mode is tied to a new configure option, --without-default-devices.
