Sent here: https://lore.kernel.org/linux-media/20261005065535.16137-1-pierre@pinon1.fr/ For the record, on the Dell (IPU7 behind an Intel CVS, 2 lanes), libcamera now picks the binned 1928x1088 mode for 1080p, and that mode still does not stream: the IPU7 firmware rejects every frame with INSYS_MSG_ERR_CAPTURE_HW_ERR_BAD_FRAME_DIM. This is the issue discussed under v1 2/2, "media: i2c: ov08x40: Do not expose the broken 1928x1088 binned mode": https://lore.kernel.org/linux-media/20260904134604.595685-1-pierre@pinon1.fr/ In short: - Jimmy relayed that the CVS firmware decodes and re-packs the sensor's MIPI stream, and only supports 3856x2176 linear and 1928x1088 sHDR, while the driver programs 1928x1088 as linear. - Sakari suggested having the CVS driver reject the other sizes. With your Yoga feeding the sensor into CAMSS, I assume there is no such vision chip in between, which would explain why the mode works there. Is that right? I'll follow up in that thread. Pierre
