From e4e05b7b3e28970bcb9c0032dc46e30950e75f18 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 7 Nov 2017 13:03:51 +0000 Subject: hw/arm: Mark the "fsl,imx31" device with user_creatable = false QEMU currently crashes when the user tries to instantiate the fsl,imx31 device manually: $ aarch64-softmmu/qemu-system-aarch64 -M kzm -device fsl,,imx31 ** ERROR:/home/thuth/devel/qemu/tcg/tcg.c:538:tcg_register_thread: assertion failed: (n < max_cpus) Aborted (core dumped) The kzm board (which is the one that uses this CPU type) only supports one CPU, and the realize function of the "fsl,imx31" device also uses serial_hds[] directly, so this device clearly can not be instantiated twice and thus we should mark it with user_creatable = false.
