Subject: [PATCH v8 07/11] virtio-gpu: Support suspension of commands processing
Date: Thu, 18 Apr 2024 22:00:36 +0300 [thread overview]
Message-ID: <20240418190040.1110210-8-dmitry.osipenko@collabora.com> (raw)
In-Reply-To: <20240418190040.1110210-1-dmitry.osipenko@collabora.com>
Add new "suspended" flag to virtio_gpu_ctrl_command telling cmd
processor that it should stop processing commands and retry again
next time until flag is unset.
