Invoke V2 is going to support enhanced invocations like CRC, poll mode, etc. This change add support for CRC mode using invoke V2 request. Signed-off-by: Ekansh Gupta <[email protected]>
For any remote call to DSP, after sending an invocation message, fastRPC driver waits for glink response and during this time the CPU can go into low power modes. With poll mode support fastrpc driver will continously poll on memory after sending message to remote subsystem which will eliminate CPU wakeup and schedule latencies resulting in performance improvement. Invoke V2 is used to support polling mode. Signed-off-by: Ekansh Gupta <[email protected]>
Invoke V2 is adding few enhanced invocation requests. Add documentation for CRC and polling mode explaining how the feature works and how it can be enabled. Also add the performance improvement data when using polling mode. Signed-off-by: Ekansh Gupta <[email protected]>
