Hi Matt, Thomas,
Some very bold out of box thinking in this area:
1. so you want to use drm scheduler and dma-fence for long running workload.
Why you want to do this in the first place?
Hi Marek,

Hi,
my platform has a DIP switch controlled multiplexer for MIPI DSI output
signals. One output has a TI SN65DSI84 (LVDS) and the other output has a TI
