Batch mode will send multiple task to kernel at one time. And its non-block poll is triggered by timer and looper. This mode will reduce the ioctl overhead on ultra multi-instance case. Main features and some notes: 1. Each client type has independence batch server. 2. Each mpp_device can attach or not attach to server independently. 3. When a device is attached to server all its tasks will be sent to kernel through the server session not original client session. 4. The tasks are sent non-block and wait in block or non-block. 5. The batch mode can only be switch on/off when hardware is not working. Change-Id: I07462d852cb002259d2873e13c12f6f8a489ba8e Signed-off-by: Herman Chen <herman.chen@rock-chips.com>
