habanalabs/gaudi2: new API to control engine cores running mode

2022-09-18T10:29:51Z

The current flow of halting the engine cores is implemented by command buffers built by the user space and sent towards the Driver. This current flow is broken since the user space does not know when the cores actually halt as sending a workload is async op. Therefore the application can not free the memory that is mapped to the engine cores. This new API allows the user space to control the running mode. The API call is sync (returns after the cores are set to the requested mode). Signed-off-by: Tal Cohen Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
