by Menna Mahmoud

Hi All, I am Menna, a Linux kernel intern- Outreahy internship. I worked on a project related to the Morello kernel. I checked the user guides and followed this: https://git.morello-project.org/morello/morello-linux, but I have a problem I couldn't create my own FVP kernel image and run it, I want to develop the kernel and update the FVP image and run it but I don't know how to do that. Could you please help me? Thanks in advance, Menna

Building MUSL with morello-sdk

by seb.horsewell＠seebyte.com

Hi all, I'm pulling the latest morello-sdk and getting the latest musl-libc repo from gitlab (https://git.morello-project.org/morello/musl-libc/) but seem to be unable to build musl-libc projects with clang. I'm following the instructions here, which are only a month old but failing at the first step of building clang. I'm using clang 13 from the morello-llvm. https://git.morello-project.org/morello/musl-libc/-/blob/morello/master/bui… Mostly I seem to get cmake errors: ``` CMake Error at CMakeLists.txt:139 (MESSAGE): libcxx isn't a known project: bolt;clang;clang-tools-extra;compiler-rt;cross-project-tests;libc;libclc;lld;lldb;mlir;openmp;polly;pstl;flang. Did you mean to enable it as a runtime in LLVM_ENABLE_RUNTIMES? ``` Again this is all in the morello-sdk, any tips?

[PATCH 0/2] Use fs labels to ensure fstab mounts root and boot

by carsten.haitzler＠foss.arm.com

[PATCH 0/1] Move to DNS usage to DHCP rather than hard-coded

by carsten.haitzler＠foss.arm.com

From: Carsten Haitzler <carsten.haitzler(a)arm.com> Using a fixed DNS IP is not right - if you DHCP fetch your IP address your DHCP server will tell you what DNS server to use - you should use that one as then at least internal DNS lookups for names behind a NAT work where a fixed 8.8.8.8 etc. won't. Do this by moving to Network Manager - it does this right. Problem then solved. CI passes except for FVP - but CI is yet again broken and no-op CI runs fail the same way https://git.morello-project.org/carhai01/morello-rootfs-images/-/pipelines/… Carsten Haitzler (1): morello: Network: Move to network manager to solve DNS context/build_debian_image.sh | 23 +++-------------------- 1 file changed, 3 insertions(+), 20 deletions(-) -- 2.25.1

[MORELLO-SDK] A simple way to port your applications to Morello

by Vincenzo Frascino

Hi All, I am glad to inform you that our SDK for Morello is finally ready. After months of hard work we are happy to share with you the results of our work. Our motto is "Let Linux developers focus on the porting of their own application" and today we are taking the first steps to deliver on that. [Morello SDK] In less than 10 minutes you should be able to setup a docker container with everything you need to build an application for Morello. - Documentation: https://sdk.morello-project.org/ - Code repository: https://git.morello-project.org/morello/morello-sdk If you want to try a demo of the SDK that runs on a Morello FVP (for more information on what is an FVP: www.morello-project.org) please have a look below: [Morello Linux] In less than 10 minutes you should be able to setup a docker container with everything you need to build and boot into a Morello Debian environment. - Documentation: https://linux.morello-project.org/ - Code repository: https://git.morello-project.org/morello/morello-linux Note: The documentation covers the instructions for Linux but if you know what you are doing and are familiar with docker no one stops you from running our solution on Windows or Mac. Are we done with it? No, by any mean. This is just the beginning and we need your help and collaboration to make sure that we improve our solution to meet developers needs: your needs! So why don't you try it and let us know your thoughts? Thanks and Regards, Vincenzo

[LLVM] Announcing the 1.6 release of LLVM with Morello support

by Silviu Baranga

Hi, The 1.6 release of LLVM with Morello support is now available. The release includes the following changes: - Added support for running baremetal on the board at EL2 in the baremetal toolchain (see the 1.6 toolchain documentation [1] for more details). - Added support for emitting ELF relocations with static linking. Using this configuration will reduce the binary size, since relocations will now take less space in the binary. This is enabled by default for the baremetal toolchain and should only be used when the C libray supports processing R_MORELLO_RELATIVE relocations. - Code generation for jump tables has been improved. - As usual, includes various bug fixes. The source code is available at https://git.morello-project.org/morello/llvm-project/-/tree/morello/release… Prebuilt binaries can be found at https://git.morello-project.org/morello/llvm-project-releases. Thanks, Silviu [1] https://git.morello-project.org/morello/llvm-project-releases/-/tree/morell…
