Subject: [PULL 06/15] util/bufferiszero: assign length_to_accel value for each accelerator case
Date: Thu, 2 Apr 2020 15:06:31 -0400 [thread overview]
Message-ID: <20200402190640.1693-7-pbonzini@redhat.com> (raw)
In-Reply-To: <20200402190640.1693-1-pbonzini@redhat.com>
From: Robert Hoo <robert.hu@linux.intel.com>
Because in unit test, init_accel() will be called several times, each with
different accelerator type.
