Hi,

Naive question from a newbie. How can this be achieved? I'd appreciate if
you could please shed some light on what steps need to be followed?

Thanks in advance,

Hi Ricardo,

If you are asking about the list of MACHINE types that Yocto Project supports, then the best place to look is in the Layer Index:

   https://layers.openembedded.org/layerindex/branch/master/layers/

Click on the “Machines” tab, click on the “Search” tab with or without a search value, and see the glorious list.

The same goes for supported layers, recipes, classes, and distro values.

You can change the “Branch” value to see the MACHINE’s per release.

Hi David,

Thanks for the prompt reply!

My question was a follow up of Khem's inquire (posted on 2014-05-02)

https://lists.yoctoproject.org/pipermail/yocto/2014-May/019387.html

Using the links you sent me, I found that the old OE-Classic branch
supports sparc32 but didn't see any sparc64

http://layers.openembedded.org/layerindex/oe-classic/recipes/

As such, I'd like to know what steps I need to follow in order to enable a
SPARCv9 machine in Yocto.

I appreciate your answer.

We support arm/aarch64/mips/mips64/ppc/ppc64/riscv64/x86/x86_64 for 
major arches in OE-Core, we also carry patches to support SH4 but do not 
test actively for it. sparc support is in there atleast I see basic 
constructs are there. Its should be possible to build upon that easily. 
But it will not work out of box to set your expectations right.

Thanks for the reply, Khem!

What steps should I follow to be able to verify the build I put together
for SPARCv9 works (or doesn't)?

I realize it is a pretty non-conventional (newbie like) question but I'd
like to follow a methodological procedure to validate the build.

I appreciate your answer.

Re: Target CPU architectures that Yocto Project Support

[Alexander Kanavin]

You start by defining 'works'. It can be anything from quickly
building an image and booting it on the target hardware to see a login
prompt, to running a massive test suite and achieving 100% pass rate.

Re: Target CPU architectures that Yocto Project Support

[Ricardo Ramirez]

[-- Attachment #1: Type: text/plain, Size: 4696 bytes --]

 Hi Alex,

You are right. I didn't define a clear scope for what I wanted to validate.
Apologies about that imprecision.

If possible, I'd like to divide the validation process into three stages

1. The system has a clean boot up process
2. The system is tested using a C-based benchmark (e.g. SPEC CPU2006)
3. The system is validated using a more complex set of testbench frameworks
(e.g. http://www.phoronix-test-suite.com/))

My immediate goal is to accomplish stages 1 and 2.

Considering the stages listed above, what steps would I need to follow?

I appreciate your help.

1. You need to create and boot an image for the target system, and run 
basic smoke tests (e.g. that you can log in, and the network is up and 
runing etc). We do this in a fully automated fashion when the target 
hardware is QEMU emulation of various machines:

bitbake -c testimage <image_name>

2. You need to place the benchmark software into the target image, by 
building and packaging it via yocto recipes that you need to write. I 
don't know if the recipes for benchmarks you mentioned are already 
available somewhere; in that case you can simply re-use that, and 
configure your image to include that. Then you boot the image on the 
target hardware and run the benchmarks.

Sparc is not an already supported architecture in OE-Core however you
should be able to extend it easily

Target CPU architectures that Yocto Project Support

Hello,

I would like to know if I could use Yocto Project to build Linux for Sparc v8 CPU architecture. I am trying to build linux with some tools for the Leon3 (opencore) CPU and I am facing errors during compilation. So I am trying to find an alternative solution to get Linux with some basic tools running on the hardware. Sorry if I have made any mistakes or if I sent to the wrong mailing list - I am a totaly newbie.


Thank you in advance.
