Subject: [PATCH v8 15/40] accel/tcg: Introduce TCGCPUOps::has_work()
Date: Mon, 27 Sep 2021 00:26:51 +0200	[thread overview]
Message-ID: <20210926222716.1732932-16-f4bug@amsat.org> (raw)
In-Reply-To: <20210926222716.1732932-1-f4bug@amsat.org>

Introduce a target-specific has_work() handler for TCG.
Eventually call it from tcg_cpu_has_work(), our
AccelOpsClass::has_work() handler.

Inspired-by: Richard Henderson <richard.henderson@linaro.org>
