Its sole purpose is to serve as a flavor which builds as quickly as possible so that developers could quickly test their core fixes in a VM (or bisect regressions). Originally, we didn't even plan to build and publish it in BuildService" https://lists.opensuse.org/opensuse-kernel/2020-01/msg00019.html Which I think is incompatible with the idea of using it as a Kata Containers kernel. As, I don't think we want to tell our (potential) future Kata users: <<here, use Kata on openSUSE with a kernel which shouldn't really be used for anything other than debugging>> :-P I mean, it's fine that we're using it right now, given the experimental stage of the whole thing, but I don't really see it fitting going forward (which is why I started the thread :-P).

If so, you need to build your own kernel. But you can still do that by linking kvmsmall and tune it with config.addon and/or patches.addon. thanks, -- js suse labs

[opensuse-kernel] kernel-kvmsmall missing uinput module.
by Stefan Seyfried 20 Jan '20

20 Jan '20

Hi kernel hackers, I tried the kernel-kvmsmall in a libvirt/KVM vm with current tumbleweed. Unfortunately, resizing the screen did not work. Usually I just have to call "xrandr -s 0" after resizing and the X server will adapt. Investigating Xorg.log differences, I found that spice-vdagent seemed to be not working. I then built and inserted the uinput module for this kernel, logged out and back in again and now resizing the VM window works again. Would it be possible to enable uinput for kernel-kvmsmall?

[opensuse-kernel] Some kmp fail to build for Leap 15.2 ARM
by Guillaume Gardet 07 Jan '20

07 Jan '20

Hi, Since mid-december, mali kmp fail to build on Leap 15.2 aarch64 with: ERROR: "mm_trace_rss_stat" [/home/abuild/rpmbuild/BUILD/driver/product/kernel/drivers/gpu/arm/midgard/mali_kbase.ko] undefined! JobHistory: https://build.opensuse.org/packages/mali-bifrost-kmp/job_history/devel:ARM:… We probably need to add: EXPORT_SYMBOL_GPL(mm_trace_rss_stat); In mm/memory.c But it is unclear why Tumbleweed (still at 5.3) and SLE15-SP2 are fine. Any idea what causes this difference? Cheers, Guillaume IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
