Subject: [Qemu-devel] [RFC PATCH v5 10/24] target/arm/arm-powertctl: drop BQL assertions
Date: Tue, 23 Jan 2018 11:54:15 +0300 [thread overview]
Message-ID: <20180123085415.3419.37058.stgit@pasha-VirtualBox> (raw)
In-Reply-To: <20180123085319.3419.97865.stgit@pasha-VirtualBox>
From: Alex Bennée <alex.bennee@linaro.org>
The powerctl code is run in the context of the vCPU changing power
state. It does not need the BQL to protect its changes.
