I was missing understanding of ivsc when I wrote the mail yesterday. Got some basic understanding yesterday after I wrote, and big thanks for confirming it, and also thanks for your ipu_dev branch. Has just cloned it, and is building as I write. Just fyi, I was trying to hack something together yesterday, and got further, but not yet working. My hack was to combine the out-of-tree ivsc drivers and firmware from * https://github.com/intel/ivsc-firmware.git * https://github.com/intel/ivsc-driver.git Though noticed that I need some changes to the sensor driver so was also building all the drivers from ipu6-drivers (with minor changes to get_pages) as out-of-tree modules. * https://github.com/intel/ipu6-drivers.git Here I used everything beside media/pci/*.ko files. I could see the sensor and got further, but was missing the last. Looking forward to try your branch. Looks much cleaner, and would be nice to get working :) /Claus > >
