Hi, after a lot of staring at the configuration it seems like this boils down to an issue within the Kconfig constraint description. Broken down to the important bits: - CONFIG_VIDEO_TW68 and CONFIG_VIDEO_SAA7134 *select* CONFIG_VIDEOBUF2_DMA_SG - Both of these options are set to *m* in the configuration provided, which means that CONFIG_VIDEOBUF2_DMA_SG will also be selected as m. According to Documentation/kbuild/kconfig-language.txt, line 101, m is set as the minimal value for CONFIG_VIDEOBUF2_DMA_SG by the selects, and as no other options select it as y, it stays m. - CONFIG_VIDEO_CAFE_CCIC is set to *y*. The header file at drivers/media/platform/marvell-ccic/mcam-core.h then sets an internal preprocessor variable in line 28: #if IS_ENABLED(CONFIG_VIDEOBUF2_DMA_SG) #define MCAM_MODE_DMA_SG 1 #endif The source code right around line 1299 in drivers/media/platform/marvell-ccic/mcam-core.c, where the undefined reference occurs, depends on MCAM_MODE_DMA_SG. This means that CONFIG_VIDEOBUF2_DMA_SG is compiled as an LKM, thus the reference for vb2_dma_sg_memops from mcam-core.c (which is statically compiled) can not be resolved in the builtin.o files and vmlinux. Unfortunately, I haven't got a solution on how to resolve that, but maybe this summary helps someone else to come up with one.
