[Qemu-devel] [PATCH 1/3] hw/arm: Mark the "fsl, imx6" device with user_c

From: Thomas Huth
Subject: [Qemu-devel] [PATCH 1/3] hw/arm: Mark the "fsl, imx6" device with user_creatable = false
Date: Wed, 1 Nov 2017 07:58:55 +0100

This device causes QEMU to abort if the user tries to instantiate it:

$ qemu-system-aarch64 -M sabrelite -smp 1,maxcpus=2 -device fsl,,imx6
Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:222:
qemu-system-aarch64: -device fsl,,imx6: Device 'serial0' is in use
Aborted (core dumped)

The device uses serial_hds[] directly in its realize function, so it
can not be instantiated again by the user.
