Subject: [PATCH v5 08/31] accel/tcg: Implement AccelOpsClass::has_work() as stub
Date: Mon, 20 Sep 2021 23:44:24 +0200	[thread overview]
Message-ID: <20210920214447.2998623-9-f4bug@amsat.org> (raw)
In-Reply-To: <20210920214447.2998623-1-f4bug@amsat.org>

Add TCG target-specific has_work() handler in TCGCPUOps,
and add tcg_cpu_has_work() as AccelOpsClass has_work()
implementation.
