[Masahiro Yamada <2021962@xxxxxxxxxxxxxxxxxx>]

"K26" is the name of the SOM (System-on-Module).

"KV260" is the name of the SOM + Base board.


I am guessing the Base board overlay was applied on Jammy, but not on Focal.

I think Jammy is correct.

Better to check U-Boot applied the overlay before booting the kernel.

BTW, I checked the focal kernel tree, but did not find "K26". Where did
that device tree come from?

Title:
  F/xilinx and J/xilinx uses different keyword in /proc/device-
  tree/compatible

Status in ubuntu-kernel-tests:
  New
Status in linux-xilinx-zynqmp package in Ubuntu:
  New

Bug description:
  While testing J/xilinx, I noticed that the keyword we use to grep from
  /proc/device-tree/compatible has to be changed into kv26 instead of
  k26 that we used for F/xilinx

  J/xilinx:
  $ cat /proc/device-tree/compatible
  xlnx,zynqmp-sk-kv260-rev1xlnx,zynqmp-sk-kv260-revBxlnx,zynqmp-sk-kv260xlnx,zynqmp

  F/xilinx:
  $ cat /proc/device-tree/compatible
  xlnx,zynqmp-smk-k26-rev1xlnx,zynqmp-smk-k26-revBxlnx,zynqmp-smk-k26-revAxlnx,zynqmp-smk-k26xlnx,zynqmp

  From what I can found on the Internet, KV260 is "a vision application
  development platform for Kria K26 SOMs (system-on-module)". But it's
  better to let the kernel maintainer (Portia) to answer that if this
  difference is expected.
