| kata-irc-bot | <fupan> Hi @shuo.chen it seemed the guest kernel didn’t set CONFIG_TRANSPARENT_HUGE_PAGECACHE=y, you can rebuild a guest kernel with it set. | 02:51 |
|---|---|---|
| kata-irc-bot | <teawater> I reproduced this issue in my part. I think maybe some config of the kata linux kernel need be open can handle this issue. | 02:57 |
| kata-irc-bot | <teawater> @shuo.chen Could you open an issue for this? | 02:57 |
| kata-irc-bot | <shuo.chen> Yeah I rebuild the kernel with CONFIG_TRANSPARENT_HUGE_PAGE and it works. I guess it is not a issue but a feature request? | 02:59 |
| kata-irc-bot | <teawater> commit 396bcc5299c281e9cf1737ad0efcd97be9f83845 Author: Matthew Wilcox (Oracle) <willy@infradead.org> Date: Mon Apr 6 20:04:35 2020 -0700 mm: remove CONFIG_TRANSPARENT_HUGE_PAGECACHE Commit e496cf3d7821 (“thp: introduce CONFIG_TRANSPARENT_HUGE_PAGECACHE”) notes that it should be reverted when the PowerPC problem was fixed. The commit fixing the PowerPC problem (953c66c2b22a) did not revert the commit; | 03:36 |
| kata-irc-bot | instead setting CONFIG_TRANSPARENT_HUGE_PAGECACHE to the same as CONFIG_TRANSPARENT_HUGEPAGE. Checking with Kirill and Aneesh, this was an oversight, so remove the Kconfig symbol and undo the work of commit e496cf3d7821. | 03:36 |
| kata-irc-bot | <teawater> CONFIG_TRANSPARENT_HUGE_PAGECACHE was removed in the Linux kernel upstream :exploding_head: | 03:37 |
| kata-irc-bot | <shuo.chen> @teawater yeah I also saw that to but with CONFIG_TRANSPARENT_HUGEPAGE , it should work. They just combine them | 03:41 |
| kata-irc-bot | <sebastian.hasler> Hi, I'm using kata containers with containerd. Is there a way to specify a drop-in config file, so that I don't have to edit/replace the default config? | 18:45 |
| kata-irc-bot | <eric.ernst> Yes, containerd allows for this | 18:48 |
| kata-irc-bot | <sebastian.hasler> How? I currently have `kata.options.ConfigPath` set to the default config file. | 18:58 |
| kata-irc-bot | <shuo.chen> ```[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.kata-qemu] runtime_type = "io.containerd.kata-qemu.v2" privileged_without_host_devices = true pod_annotations = ["io.katacontainers.*"] [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.kata-qemu.options] ConfigPath = "/opt/kata/share/defaults/kata-containers/configuration-qemu.toml"``` We use the containerd config like this | 19:58 |
| kata-irc-bot | <sebastian.hasler> @shuo.chen in your example there's no drop-in config file. You only use a single config file which holds all of the configuration. | 22:49 |
| kata-irc-bot | <shuo.chen> oh you want to use a new config file that overwrite some of the field from default config? | 22:50 |
