X-Received-From: 2a00:1450:4864:20::332 Subject: [Qemu-devel] [PATCH 34/52] minikconf: implement allnoconfig and defconfig X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: yang.zhong@intel.com, thuth@redhat.com Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" 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.
