@laijs @bergwolf @sboeuf @egernst @jodh-intel @grahamwhaley - ptal

jcvenegas

@devimc shall we move the config under 4.14.x directory to know for what kernel are done those patches?

sboeuf · 2018-04-19T22:03:42Z

@devimc Sorry if I didn't follow here, but what's the kernel config for Xen for ? Future support of Xen as hypervisor ?

jcvenegas · 2018-04-19T22:05:03Z

This looks good
A couple of comments.

Could you add some docs describing how this patches are going to be used ?
I think could be great to have or first test for this repo that takes that config and and patches and make sure the kernel builds.

jodh-intel · 2018-04-20T07:24:20Z

@devimc, @jcvenegas - I agree that it would make sense to rename the config files to show the kernel version they apply to.

@bergwolf - do you have any thoughts on this as I presume you might be raising follow-on PRs for other architectures?

why do we need autofs, fuse, and overlayfs?

good catch, we don't need it

Why disabling pv spinlock and pv time accounting?

we never enabled it. Q. why should enable it?

pv spinlock helps performance and pv time accounting corrects vCPU steal time accounting. For details, please read related Kconfig.

Please enable CONFIG_RD_GZIP since osbuilder creates the initramfs image with gzip.

enabled by default, this is a defconfig

I'm confused. So this is just part of the kernel config file and we rely on Kconfig default value for others? How about saving the final resulting .config instead? I'm not confident at all that we have covered all unneeded options here.

@devimc WDYT about this one?

@devimc you have not addressed my question about not relying on Kconfig default value. I do not want to use a defconfig because it is not clear what is enabled/disabled from the config file.

sboeuf · 2018-04-20T17:46:36Z

@devimc I know that eventually we might have Xen support as an hypervisor in Kata Containers, but we don't have it now. And my understanding is that we're advertising that we have a kernel for Xen but we cannot test it with Kata.

jcvenegas · 2018-04-20T21:14:30Z

@chavafg @devimc
Seeing that there are a couple of question regarding if something is need or not.
Could you add this repo to the CI (jenkins) and add a test for this repo that:

build this config in a kernel install it and check all works.

This will help to avoid @devimc being testing manually on every added option.

jcvenegas · 2018-04-20T21:19:17Z

Added as an issue #19

jcvenegas · 2018-04-23T15:27:08Z

@devimc as reminder you you add a doc here describing the usage of this config patches and probably how will relate with linux fork.

+popd linux-4.14.22
+make ARCH=x86 x86_kvm_4.14.x_defconfig


this is due to the config name, should we move the config name to include the prefix kata?
I am not familiar using the ARCH env variable Also are you testing this kernel with ARCH=x86 should not be x86_64?

@jcvenegas ARCH=x86 works for me, but I see in cc packaging we use x86_64, let me change it, thanks

@devimc @bergwolf @sboeuf any update on this?

egernst · 2018-04-25T15:35:40Z

@jcvenegas -- I talked with Peng on this last night. I think both of us would rather see a resulting config rather than the minimal defconfig.

devimc · 2018-04-25T16:31:36Z

@kata-containers/packaging Hey! could you please take a decision NOW!?

sboeuf · 2018-04-25T16:37:43Z

@devimc a decision about what ?
I think there are two things that have been mentioned:

Removing the Xen config as it is not used/tested yet, so no reason to introduce something we didn't test
Do not rely on defconfig as they can include unneeded component.

devimc · 2018-04-25T16:41:50Z

@sboeuf dude xen was removed I think you should take a look to the commit before ...

Do not rely on defconfig as they can include unneeded component.

really? how do you know that?

sboeuf · 2018-04-25T16:46:48Z

@devimc wow easy, I am sorry I didn't check the new version, I was just trying to summarize what was going on.
About the defconfig, I am just saying that when you apply a defconfig, you don't have control over what are the default for options that you didn't specify into the defconfig file.

Since these are selected as modules, we need to make sure the packaging script do make modules_install and include them in the rootfs image and the initrd image.
