Subject: [Qemu-devel] [PATCH 1/6] hw/arm/virt: Check that the CPU realize method succeeded
Date: Thu,  7 Dec 2017 18:14:48 +0000	[thread overview]
Message-ID: <1512670493-18114-2-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1512670493-18114-1-git-send-email-peter.maydell@linaro.org>

We were passing a NULL error pointer to the object_property_set_bool()
call that realizes the CPU object. This meant that we wouldn't detect
failure, and would plough blindly on to crash later trying to use a
NULL CPU object pointer. Detect errors and fail instead.

In particular, this will be necessary to detect the user error
of using "-cpu host" without "-enable-kvm" once we make the host
CPU type be registered unconditionally rather than only in
kvm_arch_init().
