Hi Tim

Many thanks for these instructions, and sorry for the late reply.
However, I wouldn't have forgotten to review it if you had copied the
docs@ mailing list ;-)

I have the restructured text conversion far enough along for the
'kernel-lab' to share it now. Because I was last working on this for
Yocto Project Summit 2021.11, the current qemux86 base is on
'honister' (although I am upgrading it to honister-3.4.4 tag).

Please realize there is a lot of history to this material and some of
it was done by folks that have left this mortal coil and some respect
for that posterity is included in this work. We can change and morph
in the future, once it has been captured close to what it is here.

I also have a separate workflow going for the Yocto Project Summit
2022.05 which is in Google Slides and is qemuarm64 based
('kirkstone'). Eventually I will find the time to update the
kernel-lab manual to follow suit, but our collective discussion may
impact that.

You can take a look at YP Summit 2021.11 to see a preview of what is
coming for YP Summit 2022.05 (once I figure out the pesky
printk/pr_info issue):
https://elinux.org/images/b/be/Yps2021.11-handson-kernel.pdf

Current working branch of kernel-lab manual:
https://github.com/moto-timo/yocto-docs/tree/timo/honister/kernel-lab

And the accompanying metadata training materials:
https://github.com/moto-timo/kernel-lab-layers/tree/wip-honister

The intent is that for a given release of the docs, we would have
exercises for  LTS, Stable and Mainline (really this means
current-stable, not -dev). Currently, LTS would be 5.10, Stable would
be 5.15 and Mainline would be 5.17.

The whole instructions look very good and ready for inclusion when the
mentioned repository for the lab layers exists.

I'm starting to run them.

How should we proceed? I'd suggest to:

* Publish the repository for the lab layers at the specified location
* Submit the sources to the docs@ mailing list for public review. I
have a few minor issues to report, and this could happen then.

What do you think?

So far, there's just one thing that bothers me a bit: the .bb or .conf
files that we are supposed to open could be useful to show directly in
the documentation. It looks a bit strange to talk about the contents of
a file without showing it at the same time. I know, there's a risk to
see them getting out of sync with the actual sources.

Maybe we can find a way to include the contents of files from branches
in cloned repositories. This would be handy in many places...

Thanks again,
Cheers
Michael.

Not sure if we want to add the json CVE output to honister to enable

Yeah, there is only a week left and I wasn't planning to take those
patches in my final pull request.

I will just disable it then, thanks for the info.

I plan to run the autobuilder job powering this nightly.

Currently it adds a json file for each run into the yocto-metrics
repository. These are 6MB each though so we're going to get into
silly
amounts of data rather quickly so I may have to adjust it to just
write
the latest. It would also help the size to use tabs instead of spaces
for indentation.

The autobuilder job currently throws warnings but I think Ross said
he'd send a patch to allow that to be configurable.

Also, this doesn't send the CVE emails Steve currently sends. It
would
be possible to add, I'm hoping someone might like to send some
patches!

Cheers,

Richard

2. Run cargo-bitbake inside the repository. It will produce a BB file.
3. Create a new include file with SRC_URI and LIC_FILES_CHKSUM from the BB file.

+Automated Parsec testing with runqemu
+=====================================
+
+ The Yocto build system has the ability to run a series of automated tests for qemu images.
+All the tests are actually commands run on the target system over ssh.
+
+ Meta-parsec includes automated unittests which run end to end Parsec tests.
+The tests are run against:
+- all providers pre-configured in the Parsec config file included in the image.
+- PKCS11 and TPM providers with software backends if softhsm and
+ swtpm packages included in the image.
+
+Meta-parsec also contains a recipe for `security-parsec-image` image with Parsec,
+softhsm and swtpm included.
+
+ Please notice that the account you use to run bitbake should have access to `/dev/kvm`.
+You might need to change permissions or add the account into `kvm` unix group.
+
+1. Testing Parsec with your own image where `parsec-service` and `parsec-tool` are already included.
+
+- Add into your `local.conf`:
+```
+INHERIT += "testimage"
+TEST_SUITES = "ping ssh parsec"
+```
+- Build your image
+```bash
+bitbake <your-image>
+```
+- Run tests
+```bash
+bitbake <your-image> -c testimage
+```
+
+2. Testing Parsec with pre-defined `security-parsec-image` image.
+
+- Add into your `local.conf`:
+```
+DISTRO_FEATURES += " tpm2"
+INHERIT += "testimage"
+TEST_SUITES = "ping ssh parsec"
+```
+- Build security-parsec-image image
+```bash
+bitbake security-parsec-image
+```
+- Run tests
+```bash
+bitbake security-parsec-image -c testimage
+```
+
+Output of a successfull tests run should look similar to:
+```
+RESULTS:
+RESULTS - ping.PingTest.test_ping: PASSED (0.05s)
+RESULTS - ssh.SSHTest.test_ssh: PASSED (0.25s)
+RESULTS - parsec.ParsecTest.test_all_providers: PASSED (1.84s)
+RESULTS - parsec.ParsecTest.test_pkcs11_provider: PASSED (2.91s)
+RESULTS - parsec.ParsecTest.test_tpm_provider: PASSED (3.33s)
+SUMMARY:
+security-parsec-image () - Ran 5 tests in 8.386s
+security-parsec-image - OK - All required tests passed (successes=5, skipped=0, failures=0, errors=0)

Now that we also have release notes in the documentation (see
https://docs.yoctoproject.org/migration-guides/release-notes-3.4.2.html
for example, and the source code on
https://git.yoctoproject.org/yocto-docs/tree/documentation/migration-
guides/release-notes-3.4.2.rst),
what about modifying the scripts to generate such notes directly in Sphinx
syntax, and right before a new release is made, add them to the
documentation directory?

This is in my to do list.

Chee Yang

Good morning,

I generated a Linux Image by following the intel document "Yocto Project*-based Board Support Package for Intel Atom® x6000E Series, and Intel® Pentium® and Celeron® N and J Series Pro"[1].

I built option C (mc:x86-2021-minimal:core-image-full-cmdline) using bitbake. And used bmaptool to prepare a bootable image (differently from the document, in my case the `.wic.bmap` file was not generated, only the .wic, so I had to pass the --nobmap option to bmaptool).

The Elkhart Lake CRB recognizes the bootable image, and boots into systemd-boot.

After selecting the only option in the systemd-boot bootloader, the following message is displayed: "EFI stub: Loaded initrd from command line option", and the boot process does not go any further, being stuck on a screen with this message.

I have tried, however, this same image on my desktop (a Xeon E5-2650 V3) and I can boot til the login screen and log into root. I can also test the image on qemu. But the boot process fails on the CRB.

What could be possibly hapenning?

Many thanks for the new release!

what about modifying the scripts to generate such notes directly in

This way I wouldn't have to convert the text release notes by hand, and
users would directly enjoy the HTML format, with links that are easy to

Forgot to mention that the build machine is x86_64 and I want to build for target aarch64.

This is the generated bitbake recipe:

What I also don't understand is what the recipe libstd-rs, which is provided as a recipe in poky/meta/recipes-devtools/rust, is used for or how it is used. Considering the name of the package it looks like I would need it? Adding this to DEPENDS doesn't change anything though.

It helps if you can share the recipe that you're trying to build.

Hello,

I'm trying to build a rust package which pulls openssl-sys as a dependency. I've used cargo bitbake to create the build script.

When I try to build the package using bitbake I get the following error message:
error: failed to run custom build command for `openssl-sys v0.9.72`

Caused by:
  process didn't exit successfully: `/home/martin/yocto/build/tmp/work/cortexa72-poky-linux/basestation/0.1.0-r0/build/target/release/build/openssl-sys-0c915fe76d324495/build-script-main` (exit status: 101)

    |
    = note: the `aarch64-poky-linux` target may not be installed
    = help: consider downloading the target with `rustup target add aarch64-poky-linux`

Does anyone know if it is possible to build the std (and core) crate for the rust cross compile toolchain? I'm a beginner regarding Yocto/OpenEmbedded and am really struggling to understand how the rust cross compile toolchain is build. Any help would be appreciated.

Best regards
Martin
