I am trying to test it on a Dell XPS 9320 (0AF3) laptop First - The patch series does not apply cleanly on linus 6.5-rc6, nor the linux-media master. For v6.5-rc6 I have an issue with Patch failed at 0012 media: add Kconfig and Makefile for IPU6 When you have resolved this problem, run "git am --continue". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort". error: drivers/media/pci/intel/Kconfig: does not exist in index error: patch failed: drivers/media/pci/intel/Makefile:4 error: drivers/media/pci/intel/Makefile: patch does not apply For linux media it fails after commit https://git.linuxtv.org/media_tree.git/commit/?id=dd61c2a380037166517214957790a1486ae5d348 media: mediatek: vcodec: Consider vdecsys presence in reg range check As next commit is https://git.linuxtv.org/media_tree.git/commit/?id=bda8953e8c3e7ecbbf6cb1be11790496300e3961 media: v4l: async: Drop v4l2_async_nf_parse_fwnode_endpoints() It fails on the v4l parts, and of cause the newer commits regarding v4l: async in the linux-media master branch. So the IPU6 patch series need a refresh to fit the linux-media. I did a custom branch from linus tag v6.5-rc5 with the commits from linux-media up to the "Drop v4l2_async_nf_parse_fwnode_endpoints()" and then applied the IPU6 patches on top. https://github.com/frosteyes/linux/tree/fe/v6.5-rc5/media_test With this I am able to load the IPU6 modules, but I have problems with the sensor. The sensor module is loaded - named ov01a10 but the probe function is not run - as far as I can see Also in /sys/kernel/debug/v4l2-async/pending_async_subdevices I have it as pending ipu6: [fwnode] dev=nil, node=\_SB.PC00.LNK1 Looking at the /sys/bus/acpi/devices I can see the sensor device with a status of 15 (cat OVTI01A0\:00/status) Will continue investigating, but I would like any input in getting the driver up an running and testing on this Dell laptop. I think it should be very close to working. Regards Claus Stovgaaard
