Subject: [PATCH v2 0/3] drm/virtio: rework command batching
Date: Fri,  7 Feb 2020 14:13:56 -0800	[thread overview]
Message-ID: <20200207221359.187340-1-olvaffe@gmail.com> (raw)
In-Reply-To: <20200206192214.86818-1-olvaffe@gmail.com>

Hi,

This series replaces the global disable_notify state by command-level bools to
control vq kicks.  When command batching is applied to more places, this
prevents one process from affecting another process.

v2: update to this convention

  virtio_gpu_cmd_foo: add foo and commit
  virtio_gpu_add_foo: add foo but do not commit

However, the spinlock is now grabbed twice in both add and commit.
