Two things around it have. An ipu-bridge entry for this sensor is now on th= e list and has been tested on a second Surface Pro 11, so the OV13858 is abou= t to be reachable on Lunar Lake by more than one machine. And that second machine exists. The measurements in the patch are from one device, which I would rather say plainly than leave implied; if a confirmation on hardware other than mine would help, I can ask for one. One note that is worth more now than when I sent it. The gain table came fr= om raw Bayer at the ISYS capture node, not through libcamera, so the GPU debay= er fault that has turned up on this hardware in another thread this week canno= t reach it. The luma cross-check below the scissors did go through the softwa= re ISP, but it compares before against after on the same path. Sergey
