It also depends on enabling the streams API right? At least I need to do so to be able to use the TPG. Out of curiosity do you know the plan to enable it by default upstream? > The drivers have been tested on the following hardware combinations, > but > further testing is welcome to ensure no / minimal breakage: > * Raspberry Pi 5 + MAX9296A + 2xMAX96717 + 2xIMX219 > * Raspberry Pi 5 + MAX96714 + 1xMAX96717 + 1xIMX219 > * Raspberry Pi 5 + MAX96716A + 2xMAX96717 + 2xIMX219 > * Raspberry Pi 5 + MAX96712 + 4xMAX96717 + 4xIMX219 > * Raspberry Pi 5 + MAX96724 + 4xMAX96717 + 4xIMX219 > * Raspberry Pi 5 + MAX96792A + 1xMAX96793 + 1xMAX96717 + 2xIMX219 > * Raspberry Pi 5 + MAX96792A + 2xMAX96717 + 2xIMX219 > * Renesas V4H + MAX96712 + 2xMAX96717 + 2xIMX219 I tested the TPG on Renesas V3U + MAX96712 and it works as just as good or better then the staging driver this work makes obsolete. -- Kind Regards, Niklas Söderlund
