We are working and nearly done on a layer that would live on top
of meta-morello and that contains purecap user space libraries that
live in a purecap sysroot in parallel to the usual c64 packages.
Adding rpath the the compiler flags simplifies that work.
Further more user space recipes shall inherit yet another class that will
override the $libdir $prefix etc. variables found in bibtake.conf to
reduce the amount of hoops one has to jump through when doing the above
sysroot trick and working with Yocto.
For that to work, two of the paths in the llvm class need to
be hardcoded until a more elegant solution is found (possibly moving
overriding of all paths into the llvm-class itself, as the BSP does not
care about user space paths anyway).
Pawel Zalewski (2):
classes: add rpath to the compiler flags and fix paths
config: fix path for purecap sysroot, drop c64 flag

Hi All,
I am glad to inform you on the availability of a new version of our SDK and
base rootfs images for Morello (1.7.0). After months of hard work we are happy
to share with you what we put together.
Honoring our motto "Let Linux developers focus on the porting of their own
application", we feel that this is another steps in the right direction.
[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
New in 1.7.0:
- GDB support with Capabilities.
- Support for vDSO in musl.
- Initial support for compartments (limited demo of basic cases) [1].
- New versions for compilers and C libraries.
[1] https://git.morello-project.org/morello/morello-examples
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.
New in 1.7.0:
- Updated Kernel ABI with initial security support.
- Support for vDSO in kernel and C library.
- New versions for compilers and C libraries.
- Basic Compartment Demos.
- Bug fixing and polishing of existing features.
Note: This release does not include a new version of the Android environment.
Further Android releases are now deprecated. Ongoing releases will focus on
the Morello Linux Environment.
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
The 1.7 version of morello musl is available with
new features:
- Support purecap VDSO.
- Support static linking with R_MORELLO_RELATIVE relocs,
linking with old caprelocs still works.
bug fixes:
- Ensure musl builds with gcc and the binutils linker.

https://git.morello-project.org/morello/musl-libc
Hi,
The 1.7 release of LLVM with Morello support is now available. This binary and source release is for baremetal and for Linux.
The release includes the following changes:
- Added benchmark ABI for purecap.
- Added shadow call-stack for hybrid.
- Added a warning on the deprecated usage of c64 in the arch string. Instead, specify the ABI separately.
- As usual, the release 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,
Simon
Slept on this one due to holidays, this series of patches
bumps the release tags/branches to 1.6.1 while we wait for
release 1.7
Musl was updated to 1.6.1 before the actual 1.6.1 release
in 1.6 branch...
Pawel Zalewski (5):
rom-binaries: update version to 1.6
linux-kernel: update version to 1.6.1
gdb: use the latest revision
llvm: update version to 1.6.1
board-firmware: update version to 1.6.1

Hi,
A "getting started" guide for Morello GDB is now available as part of
the Morello SDK documentation: https://sdk.morello-project.org/docs/gdb/
This guide includes instructions on how to build Morello GDB in various
situations and how to run it, as well as some information regarding the
Morello-related features.
If you have any question related to this guide, please feel free to ask
in reply to this email or on the linux-morello-distros list.
Cheers,
Kevin
