Hello, this series is based on Tomi's "v4l: subdev internal routing and streams": https://patchwork.linuxtv.org/project/linux-media/list/?series=6197 With a few out-of-tree patches for GMSL support on top. The full tree for testing is available at: https://git.sr.ht/~jmondi_/linux/log/multistream/tomba-v8/gmsl The series aims to 1) Plumb into Tomi's v4l2 subdev streams and routing to compare it with the previous implementations of multistream support 2) Add support for multiplexed streams to R-Car VIN, CSI-2 and MAX9286 First of all, I found the multistream support as implemented by Tomi very nice to work with. I have expressed my views on the subdev state handling in the review of his series, but routing handling is nice to work with! kudos! The GMSL and R-Car implementation which results from this is -almost- working. Capturing with 4 cameras works (at least no regressions) but capturing a single VC on any instance of VIN results in the usual 'green frame of despair'. Clearly there's something to fix in the capture chain, but the plumbing into the new API should be sane. Before debugging in detail the capture chain I would like the plumbing to be validated. For testing, I have re-proposed Niklas' patches on top of v4l2-ctl to control routing and ported them to this last version. Support for state-based format handling has been added on top. Two simple scripts to be deployed in vin-test have been used to set routing and capture frames. Both are available at: https://git.sr.ht/~jmondi_/v4l2-utils https://git.sr.ht/~jmondi_/vin-test-multi Thanks j Jacopo Mondi (5): media: max9286: Implement multiplexed support media: max9286: Apply routing configuration media: max9286: Implement routing validation media: rcar-csi2: Implement multiplexed support media: rcar-vin: Support multiplexed CSI-2 receiver drivers/media/i2c/max9286.c | 452 ++++++++++++++------ drivers/media/platform/rcar-vin/rcar-csi2.c | 289 ++++++++++--- drivers/media/platform/rcar-vin/rcar-dma.c | 3 +- 3 files changed, 551 insertions(+), 193 deletions(-) -- 2.32.0
