[Kernel-packages] [Bug 2021962] Re: F/xilinx and J/xilinx uses different keyword in /proc/device-tree/compatible
The device trees comes directly from the Xilinx kernel (https://github.com/Xilinx/linux-xlnx) . It seems like in the focal kernel the overlay for the KV260 SOM did not set a compatible string so the it fell back to the compatible string defined by the baseboard (zynqmp-smk-k26-revA.dts) . When a device tree for rev B of the board was added the compatible string was added to the rev A device tree as well. The change was added here: https://github.com/Xilinx/linux-xlnx/commit/70604467dc949d3b77eabaa1288365cb25b2ec23#diff-f19b970e083cc67c8063c7698b0bb6554d69d43190d355adc20945526eda5831 I agree with Masahiro that Jammy is correct. Since the device trees are not in the kernel build and are provided by Xilinx I don't think this is something we can backport to Focal. ** Changed in: linux-xilinx-zynqmp (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-xilinx-zynqmp in Ubuntu. https://bugs.launchpad.net/bugs/2021962 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: Won't Fix 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)".

"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? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-xilinx-zynqmp in Ubuntu. https://bugs.launchpad.net/bugs/2021962 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)".
