For jammy a test kernel is available to test before I sent the SRU . Kernel version: 5.15.0-1033.37+testing08062024 Tag (pushed to launchpad.net/~canonical-hwe-team/limerick/+git/linux-xilinx-zynqmp): Ubuntu-xilinx-zynqmp-5.15.0-1033.37+testing08062024
1. Add limerick-test from your archive subscriptions to /etc/apt/sources.list 2. Run `sudo apt update` The test kernel is signed by launchpad, not the Canonical keys so you need to add keys it complains about. `sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key>` 3. Install the kernel directly, I did not provide a meta package so you need to install `linux-image-<version>-xilinx-zynqmp` instead of `linux-image-xilinx-zynqmp` `sudo apt install linux-image-5.15.0-1033-xilinx-zynqmp` 4. Reboot and check the version is correct. It should say `Linux kria 5.15.0-1030-xilinx-zynqmp #37+testing08062024` -- 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/2055237 Title: Backport ps uart RS485 driver Status in linux-xilinx-zynqmp package in Ubuntu: Confirmed Status in linux-xilinx-zynqmp source package in Jammy: Incomplete Status in linux-xilinx-zynqmp source package in Noble: Fix Committed Bug description: [ Impact ] * Backports support for rs485 to the uartps driver from the tty staging tree * One device tree patch is taken from the vendor's tree . [ Test Plan ] * Testing is needed to ensure this doesn't break the serial console on current platforms. QA will develop a new automated test to be integrated into cert testing * Testing of the RS485 port will be integrated into the cert testing for the KD240 [ Where problems could occur ] * The patches have not landed in mainline and are being pulled from the maintainers tree. There is a risk they will be rejected from mainline. * One patch is not in mainline and only exists on the vendor tree , it is a device tree change. [ Other info ] * The following 3 patches are required from the tty-dev tree. All other patches were pulled in to support the backport. 1. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=32152467ffac3b79eae7313959c310946b0e6072 2. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=74231ab6cc2d02303ddf1fabd878756c52f788a5 3. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=fccc9d9233f918ee50cf2955ae7134a7f3418351 4. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=cc3236cd758b07c1f36cabd55ea1740f0881faa0 5. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=b4337685010990385901405cc317a5a46b147b5a 6. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?h=tty-next&id=e3896be240780ccade65cc6cc8925c6f12e7f6c6 7. https://github.com/Xilinx/linux-xlnx/commit/6472141dd7401ff43fc0fbb3dbc253454c5be2ee To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-xilinx-zynqmp/+bug/2055237/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
