Where yocto assign default kernel?

There are many kernel *.bb in 

~/poky/meta/recipes-kernel/linux

I don't have PREFERRED_PROVIDER_virtual/kernel defined in local.conf

I also include meta-intel layer, I think meta-intel has it's kernel recipe also.

After built the yocto image, boot, and login, type 'uname -a' result is

Linux genericx86-64 5.4.20-yocto-standard xxxxx

I think yocto select it's poky kernel, but I can't find where this default setting located. ( which file setting this kernel )

Solution

  • Usually you can find it in the machine conf in :

    meta-yourmeta/conf/machine/yourmachine.conf

    The list of supported kernels by your machine is in recipes-kernel of your BSP.
