sdk_dpaa missing from mainline kernel?

It seems that freescale/sdk_dpaa is missing from the mainline kernel.

There seem to be a freescale/dpaa but that doesn't seem to work with the ethernet interfaces of the ls1043ardb board as it fails with:

What would be the correct mainline driver to use?

Hello Francois Gervais,

The followings are kernel options of upstream dpaa driver.

Repo:  git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Dtb: fsl-ls1043a-rdb.dtb

 

FSL_FMAN=y

FSL_DPAA=y

FSL_DPAA_ETH=y

The mainline Kernel doesn't include freescale/sdk_dpaa, if you need it, you need to do the porting from LSDK.

Thanks,

Yiping

I do have those configs but it fails with the error shown in the first post.

Any idea why?

Please use the attached Kernel configuration to build Kernel image, which is provided by the testing team.

Hello,

I met the same issue on kernel-default-5.3.18-24.49.2... and cannot build with the option you mention...any additional idea for that?
