We are setting up a device that uses an external BNC sync towards numerous GPUs. In order to save time on startup, we are using NVAPI to configure framelock across all devices. One issue we are having is the Sync Server is defaulting to Vsync, and not using the external BNC connection for its timing, causing manual effort.
I am a little confused on how to configure NVAPI with the external BNC output, based on the documentation:
NvU32 syncSourceIsOutput:1; //!< Set this to make house sync as an output; valid only when NV_GSYNC_CONTROL_PARAMS::source is NVAPI_GSYNC_SYNC_SOURCE_VSYNC on P2061 boards.
//!< syncSourceIsOutput should always be NVAPI_GSYNC_SYNC_SOURCE_HOUSESYNC i.e. 0 on P2060 boards or when NV_GSYNC_CONTROL_PARAMS::source is set to NVAPI_GSYNC_SYNC_SOURCE_HOUSESYNC.
So what would I need to set in order for the Framelock server to use the external BNC instead of based of VSYNC?
Appreciate it!
