k8s/k3s: add kernel configuration features

2021-03-16T03:15:42+00:00

We already have docker and some other fragments that are relevant to k3s/k8s, but the addition of ipset as a depends for k3s highlights that we should have a reference configuration that sets all the options for proper opration and runtime dependencies. When k8s or k3s are distro features, we'll apply the new fragment to any kernel that supports fragments (and matches the supported versions). Signed-off-by: Bruce Ashfield

kernel: drop 5.8 configs

2021-01-16T03:50:49+00:00

The 5.8 kernel is being dropped in oe-core, which means we don't test the 5.8 integration any more .. so we drop the .inc for the configs. Signed-off-by: Bruce Ashfield

kernel: add 5.10 include file

2021-01-05T21:34:32+00:00

oe-core now has a 5.10 reference kernel, so we need a 5.10 include file to pick up our configurations. Signed-off-by: Bruce Ashfield

linux-yocto: add cgroup-hugetlb config

2020-11-19T16:07:33+00:00

Add kernel config fragment for CONFIG_CGROUP_HUGETLB This is a recommended config for Kubernetes and k8s will throw a warning if it is not present. Signed-off-by: Tim Orling Signed-off-by: Bruce Ashfield

kernel: fix conditional application of fragments

2020-10-08T22:33:41+00:00

using bb.utils.contains wasn't able to match on the substring "type=kmeta" to enable the conditional inclusion of fragments and KERNEL_FEATURES. We switch to a python string only method so we can fix the fragment application Signed-off-by: Bruce Ashfield

kernel: add 5.8 linux-yocto include file

2020-10-06T18:20:38+00:00

Adding the version specific include for linux-yocto 5.8. Signed-off-by: Bruce Ashfield

config: make kernel meta data include more specific

2020-10-06T18:16:24+00:00

Rather than only matching on the major/minor version, we should also check that the SRC_URI contains a "type=kmeta", to indicate that a kernel-meta data repository is available. This allows fragment enabled kernels, that don't want to use the main kernel meta data repository to not throw an error (when their version matches one of the reference kernels). This can potentially mask runtime issues (since kernel configuration options may not be present in the final kernel), but it makes the layer more usable, so we take the tradeoff.

lxc: drop RT_GROUP_SCHED

2020-07-13T12:40:38+00:00

The group scheduling options in the lxc fragment were initially used to support performance guaranteed systems using containers. This option now causes issues with systemd runtimes and the original feature it implemented is no longer relevant Signed-off-by: Bruce Ashfield

kernel: drop 5.2 bbappend

2020-03-03T16:21:15+00:00

5.2 has been removed from core, so we drop the 5.2 bbappend to match. Signed-off-by: Bruce Ashfield

linux-yocto/xen.cfg: update Xen KConfig fragment entries

2020-02-27T21:59:22+00:00

CONFIG_XEN_MAX_DOMAIN_MEMORY has been retired since kernel commit: 197ecb3802c04499d8ff4f8cb28f6efa008067db xen/balloon: add runtime control for scrubbing ballooned out pages CONFIG_XEN_SCRUB_PAGES has been replaced with CONFIG_XEN_SCRUB_PAGES_DEFAULT since kernel commit: c70727a5bc18a5a233fddc6056d1de9144d7a293 xen: allow more than 512 GB of RAM for 64 bit pv-domains Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield
