Subject: [kvm-unit-tests PATCH v2 4/8] arm64: its: Handle its command queue wrapping
Date: Thu, 2 Jul 2020 11:01:28 +0800 [thread overview]
Message-ID: <20200702030132.20252-5-wangjingyi11@huawei.com> (raw)
In-Reply-To: <20200702030132.20252-1-wangjingyi11@huawei.com>
Because micro-bench may send a large number of ITS commands, we
should handle ITS command queue wrapping as kernel instead of just
failing the test.
