I have added 'CONFIG_V4L2_MEM2MEM_DEV=y' to my 'imx_v6_v7_defconfig'
and do a "make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi-
imx_v6_v7_defconfig", I don't see CONFIG_V4L2_MEM2MEM_DEV being set to
'y' in .config that was automatically generated.
I think I am making changes to the right 'imx_v6_v7_defconfig' file
since when i add
'CONFIG_V4L_TEST_DRIVERS=y' to 'imx_v6_v7_defconfig', I see
'CONFIG_V4L_TEST_DRIVERS=y' in .config when I do "make ARCH=arm
CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- imx_v6_v7_defconfig"
I am not sure why CONFIG_V4L2_MEM2MEM_DEV is not being set when I put
'CONFIG_V4L2_MEM2MEM_DEV=y'
And from the Kconfig, V4L2_MEM2MEM_DEV only depends on VIDEOBUF2_CORE
# Used by drivers that need v4l2-mem2mem.ko
config V4L2_MEM2MEM_DEV
tristate
depends on VIDEOBUF2_CORE
and I have CONFIG_VIDEOBUF2_CORE=y
Thank you.
