Thanks Nathan for your quick response.

No problem, we understand and respect your policy. We will keep the security (or other critical) patches we would like to apply/backport to linux-xlnx kernel in our own layer (meta-enea).

Best regards

Hi Sona,

In regards to the maintenance policy for the linux-xlnx kernel in the meta-xilinx layer. This kernel is the linux-xlnx kernel that Xilinx provides as part of "Xilinx OSL". In the meta-xilinx layer we directly use this kernel, we avoid patching it within meta-xilinx except under very specific circumstances (e.g. backporting bug fixes).

If you would like to query the policy for linux-xlnx itself or contribute your patches to linux-xlnx contact the git at xilinx.com mailing list.
