Hi all.

I'm porting and old system based on Krogoth to Dunfell.

In Krogoth the kernel was linux-imx.

Now in Dunfell which is the right kernel?

Depends on what you define as "right". :)

If you build any`fsl-` distro, then you should use either `linux-imx`
of `linux-fslc-imx` kernel. If you rather opt for any of `fslc-`
distro, then the kernel provider would be set to `linux-fslc`.


linux-fslc o linux-fslc-imx?

- `linux-fslc` is an upstream kernel (from stable korg), which has few
patches not upstreamed yet
- `linux-fslc-imx` is NXP kernel with latest patch level applied from
stable korg. This is based on the NXP release (2.1.0 in [dunfell]),
and then maintained in terms of security fixes applied in LTS branch.
- `linux-imx` is a "pure" NXP kernel, which is provided as a part of
their release(s). Current NXP release version present on the [dunfell]
branch is 2.1.0



Thanks all

For a novice to NXP Freescale builds, what setup would you
      recommend as a basic test Yocto build for a Wandboard IMX6 dual
      lite system in order to test the performance of the hardware video
      processing system using gstreamer*imx (VPU etc) ?

    
Would fslc-x11 or fslc-xwayland distro with the linux-fslc-imx
      kernel be the best approach or would some fsl-* distro with the
      linux-imx kernel be the best approach ?

    
The standard Wandboard build uses linux-fslc which does not seem
      to support the imx hardware features and so I am trying to build a
      suitable test platform but having no luck trying various build
      combinations that either wont build or wont run properly in
      various ways, so any pointers would be gratefully received !
