There's multiple issues at play here: 1) This is not a module compile-time dependency issue, but rather a run-time dependency issue, which AFAIU dracut is not resolving today. As a result the JeOS images in openSUSE:Factory:ARM etc. contain a number of add_drivers entries to load such extra modules: https://build.opensuse.org/package/view_file/openSUSE:Factory:ARM/JeOS/conf… That is of course ugly and would be nice to get resolved differently. Dracut would need to parse the Device Tree in /sys/firmware/ to discover what regulator, clock, power domain, etc. nodes are being referenced, then read their "compatible" strings and resolve them to the modules to add. The kernel uses generic API calls such as clk_get() and regulator_get(), thus no compile-time dependency for e.g. mmc modules. However when updating from 4.13 to 4.14 or from 4.14-rc4 to -rc8 it would've still read the current Device Tree and not discovered this new dependency for next boot. And Kiwi images get built in KVM, which will have a different Device Tree than the user's system or even ACPI. So I don't see a full solution yet. Let me know if I should report this somewhere upstream - it didn't seem a distro-specific issue for our Bugzilla. https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_troubleshoo… explains what info to include in a bug report, but not actually where to file it. ;) No link on dracut.wiki.kernel.org either. 2) axp20x-rsb driver does have MODULE_DEVICE_TABLE(of, ...), so it is unclear to me why the DT -> module resolution for auto-loading is not working here. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dri… It is almost certainly an upstream kernel issue, possibly in sunxi-rsb bus driver. Stefan has already reported this on #linux-sunxi. > Otherwise, the "proper" dracut patch would > looks something like the attached one. Hm, instmod is just the equivalent of "add_drivers", is it? That would not be enough here. Also not all ARM systems need this driver, it's an extra chip on some boards only. What you could do is more generally add all =drivers/mfd drivers. But if we keep adding drivers by category instead of addressing the underlying discovery issue, we risk at some point the initrd getting too large for low-RAM systems.

Without such an initrd change it will wait indefinitely for the root partition on SD card on next boot. Selecting an older kernel in GRUB will not help - only manually loading an older dtb in U-Boot can help (if e.g. you had multiversion enabled).

[opensuse-kernel] TW 4.14.0 kernel fault on Chromebook snow (ARM exynos5250)
by Guillaume Gardet 21 Nov '17

21 Nov '17

Hello, On opensuse-arm list a kernel fault for 4.14.0 (latest TW kernel) has been reported. Here is the kernel trace: http://paste.opensuse.org/96574215 Note that previous kernel 4.13.* was ok. Any idea? Guillaume -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Leap 4.4.92 : Story of kernel warnings that finish to be a total lost of data
by Bruno Friedmann 16 Nov '17

16 Nov '17

Hi all, Some times ago (after 4.4.92 hit Leap update repository) I've filled the following bug https://bugzilla.opensuse.org/show_bug.cgi?id=1064533 due to warnings and kernel trace about a raid10. Yesterday, after checking every disk with smart test long and as none of them reported an error I've readded the previously failing harddrive. There was one suspicious things, the resynchronisation at half an hour of the estimate time suddendly was ok. I've rebooted the server at that time, and then start to cry (just a bit), filesystem stored in lv or vm image were all destroyed (fsck.ext4 couldn't fix it auto, and even forced, when you tried to rewrite on it it failed) I've added all the informations I can for the moment to the mentionned bug. But I guess there's a number missing, Don't hesitate to comment here, or directly in the bug and ask for more information. The system as it is should still be present during the next 10 days. Thanks for your help and advise. -- Bruno Friedmann Ioda-Net Sàrl www.ioda-net.ch Bareos Partner, openSUSE Member, fsfe fellowship GPG KEY : D5C9B751C4653227 irc: tigerfoot -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

A PAE-enabled kernel has a slight overhead, but this is likely more than compensated by hitting the guests swap later. This does not change the 3GByte per process limit, which may cause failing linker runs. Using a 64bit linker is much more effort, so I would vote for a PAE kernel first and *if* we still see OOM errors, reconsider if we should go the 64bit userspace route (i586 is quite dead, but armv7l may stay for a bit longer). CC'ed opensuse-kernel, as I already sent a patch addressing kernel-obs-build a week ago.

[opensuse-kernel] enabling CONFIG_IMA and friends in the Tumbleweed kernel
by Marcus Meissner 07 Nov '17

07 Nov '17

Hi, The Security Team is currently evaluating IMA/EVM binary/file protection mechanisms. Most of the stuff lives only in Tumbleweed, so could someone (Jeff Mahoney?) please enable CONFIG_IMA and friends similar to Leap 42 and SLES?

[opensuse-kernel] [PATCH] rpm/kernel-obs-build.spec.in: use (l)pae kernel on armv7l/ix86
by Stefan Brüns 06 Nov '17

06 Nov '17

A non-pae kernel only uses up to 3 GByte of physical RAM, thus a memory constraint for an obs worker is essentially ignored. Although the per-process memory is still limited, parallel builds can use more memory. --- kernel-source-opensuse, packaging branch --- rpm/kernel-obs-build.spec.in | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/rpm/kernel-obs-build.spec.in b/rpm/kernel-obs-build.spec.in index 230b97f126..d47d138bbb 100644 --- a/rpm/kernel-obs-build.spec.in +++ b/rpm/kernel-obs-build.spec.in @@ -35,10 +35,20 @@ BuildRequires: util-linux BuildRequires: kernel-vanilla %define kernel_flavor -vanilla %else +%ifarch %ix86 +BuildRequires: kernel-pae +%define kernel_flavor -pae +%else +%ifarch armv7hl armv7l +BuildRequires: kernel-lpae +%define kernel_flavor -lpae +%else BuildRequires: kernel-default %define kernel_flavor -default %endif %endif +%endif +%endif %if 0%{?rhel_version} BuildRequires: kernel -- 2.14.3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org
