[PATCH 1/2] gitlab: Introduce Loongarch64 runner
Posted by Philippe Mathieu-Daudé 2 years, 1 month ago 
Full build config to run CI tests on a Loongarch64 host.

Forks might enable this by setting LOONGARCH64_RUNNER_AVAILABLE
in their CI namespace settings, see:
https://www.qemu.org/docs/master/devel/ci.html#maintainer-controlled-job-variables

Does this system really have more than 40 CPU threads? Or is this a 
copy-n-past from one of the other scripts? In the latter case, I'd suggest 
to adjust the --ignore=40 to a more reasonable value.

No,  only 32.   I think it should be --ignore=32 or 16.

I create a same runner on this machine,  and I  find  some check error.
but I am not sure how to fix it. :-)

--ignore=32 then also does not make much sense, that would still be the same 
as simply omitting the -j parameter. I guess --ignore=16 should be fine.

Seems to be related to RAM backing... for example, the erst-test is failing, 
which is doing something like:

     setup_vm_cmd(&state,
         "-object memory-backend-file,"
             "mem-path=acpi-erst.XXXXXX,"
             "size=64K,"
             "share=on,"
             "id=nvram "
         "-device acpi-erst,"
             "memdev=nvram");

So it seems like -object memory-backend-file" is not correctly working in 
your gitlab runner? Is there some setup missing?

Hi,

We tested this  on
LoongArch host with the 5.10 kernel,  (openEuler 22.03),
x86_64 host with 5.10 kernel, (openEuler 22.03)
x86_64 host with 5.15kernel , (Ubuntu 20.04.3 LTS)

and didn't get any error.

but the CI machine use the  6.7_rc4 kernel.
we didn't update the x86_64 host kernel to tested this.

Is it possible that the new kernel is causing the problem?

This is my runner config.

I create a project runner 'loongarch64' for my branch ci-master.
Do we need some special configuration?

and  I just './configure  --target-list="x86_64-softmmu" 
--enable-debug'  on LoongArch host.   make , make check.
I got the same error.
