| Summary | 0001449: CONFIG_VIDEOBUF2_DMA_CONTIG=m | ||||
| Description | videobuf2-dma-contig.ko.xz is missing to build intel ipu6 drivers | ||||

As noted in bug#1447, CONFIG_VIDEOBUF2_DMA_CONTIG is _not_ configurable. According to: https://boxmatrix.info/wiki/Property:CONFIG_VIDEOBUF2_DMA_CONTIG It may be enabled by selecting CONFIG_VIDEO_CAFE_CCIC. However this is not easily achievable. Maybe ask Pablo and see if he can come up with a usable config? |

Well I'm a little confused, the other v4l2-core drivers are also not configurable but provided in kernel-ml 6.8.9 https://www.kernelconfig.io/CONFIG_VIDEOBUF2_CORE?kernelversion=6.8.9 https://www.kernelconfig.io/CONFIG_VIDEOBUF2_DMA_SG?kernelversion=6.8.9 https://www.kernelconfig.io/CONFIG_VIDEOBUF2_MEMOPS?kernelversion=6.8.9 https://www.kernelconfig.io/CONFIG_VIDEOBUF2_V4L2?kernelversion=6.8.9 https://www.kernelconfig.io/CONFIG_VIDEOBUF2_VMALLOC?kernelversion=6.8.9 /lib/modules/6.8.9-1.el9.elrepo.x86_64/kernel/drivers/media/common/videobuf2/videobuf2-common.ko.xz /lib/modules/6.8.9-1.el9.elrepo.x86_64/kernel/drivers/media/common/videobuf2/videobuf2-dma-sg.ko.xz /lib/modules/6.8.9-1.el9.elrepo.x86_64/kernel/drivers/media/common/videobuf2/videobuf2-memops.ko.xz /lib/modules/6.8.9-1.el9.elrepo.x86_64/kernel/drivers/media/common/videobuf2/videobuf2-v4l2.ko.xz /lib/modules/6.8.9-1.el9.elrepo.x86_64/kernel/drivers/media/common/videobuf2/videobuf2-vmalloc.ko.xz |

I rebuilt a kernel-ml with CONFIG_VIDEOBUF2_DMA_CONTIG=m to be sure and yes there is no kmod(videobuf2-dma-contig.ko) at the end I'm digging deeper with dependencies provided in your link above, I'm sure I'm not far from the expected result |

Right, you cannot just add the option manually. It is not configurable by the user. All dependencies must be met and that's the challenging part. |
