Force rebuild to regenerate .ko

Force rebuild to regenerate .ko

I've a Intel Ethernet driver, ixgbe.ko.  I made some changes (debug logs) to the source file.  How do I force the .ko to be regenerated within yocto environment, without rebuilding the entire yocto code base?

I tried to do bitbake of the image name earlier, but bitbake decides that there's nothing to be done.  This is even after I'd removed the cache and sstate directories.

Thanks,
Raymond

Please add more details.


For example, where ixgbe.ko resides (what layer)?

If it is in Linux kernel (linux-yocto package), then just:

$ bitbake linux-yocto -c cleanall

$ bitbake linux-yocto

I've meta-intel and poky.  I'm not sure which layer it's in, as an attempt to find/grep files with ixgbe in the recipes directories doesn't turn up anything.  The source seems to be downloaded to work-shared sub-directory during the bitbake process.

The .ko file is located in the following path:
tmp/work/intel_corei7_64-poky-linux/core-image-sato/1.0-r0/rootfs/lib/modules/4.4.26-yocto-standard/kernel/drivers/net/ethernet/intel/ixgbe/ixgbe.ko

Thanks,
Raymond
