+title: Mediatek Video Decode Accelerator With Multi Hardware

+
+description: |
+ Mediatek Video Decode is the video decode hardware present in Mediatek
+ SoCs which supports high resolution decoding functionalities. Required
+ master and component node.
+
+ About the Decoder Hardware Block Diagram, please check below:
+
+ +---------------------------------+------------------------------------+
+ | | |
+ | input -> lat HW -> lat buffer --|--> lat buffer -> core HW -> output |
+ | || | || |
+ +------------||-------------------+---------------------||-------------+
+ || lat thread | core thread || <master>
+ -------------||-----------------------------------------||----------------
+ || || <component>
+ \/ <----------------HW index-------------->\/
+ +------------------------------------------------------+
+ | enable/disable |
+ | clk power irq iommu port |
+ | (lat/lat soc/core0/core1) |
+ +------------------------------------------------------+
+
+ As above, <master> mean in master device, <component> mean in component device.
+ The information of each hardware will be stored in each component device. There
+ are two workqueue in master device: lat and core. Enable/disable the lat clk/power/irq
+ when lat hardware need to work through hardware index, core is the same.
+
+ Normally the smi common may not the same for each hardware, can't combine all
+ hardware in one node, or leading to iommu fault when access dram data.
