Hi, I'm building a customized OpenWrt image for my project. I have enabled the
kmod-ifb kernel module in the
make menuconfig. But when I try to add an ifb device, I get this error:
# ip link add name br-lan-ifb type ifb
ip: RTNETLINK answers: Not supported
I am running OpenWrt in virtualbox.
modprobe ifb or else
lsmod | grep ifb
I think ifb module is not loaded in the kernel
# modprobe ifb
failed to find a module named ifb
I'm sure I've enabled
kmod-ifb, I can also see that it's already installed:
# opkg install kmod-ifb
Package kmod-ifb (5.10.176-1) installed in root is up to date.
I don't know why
ifb module can't be found and not loaded.
I think the image builder is not compiling the
ifb module. Here's a portion of my
.config which clearly shows ifb was enabled along side
# CONFIG_PACKAGE_kmod-igbvf is not set
But only the
ifb.ko is not present in the kernel modules directory
igc.ko is present.
