Subject: [PULL 12/15] python/qemu: accel: Add list_accel() method
Date: Tue, 17 Dec 2019 00:15:18 -0500 [thread overview]
Message-ID: <20191217051521.1239-13-crosa@redhat.com> (raw)
In-Reply-To: <20191217051521.1239-1-crosa@redhat.com>
From: Wainer dos Santos Moschetta <wainersm@redhat.com>
Since commit cbe6d6365a48 the command `qemu -accel help` returns
the list of accelerators enabled in the QEMU binary. This adds
the list_accel() method which return that same list.
