Erase i686 from the kernel package's repository?
by Paul Bolle 22 Apr '21

22 Apr '21

Hi Justin, Fedora 31's release is imminent. This means that some time ago Fedora passed the point where (F31 and later) i686 releases were still possible, doesn't it? If so, could we please clean the kernel package's repository of all the things that are only relevant for i686? Because that would make my plans for the config generation [1] just a bit easier. Thanks, Paul Bolle [1] See https://lists.fedoraproject.org/archives/list/kernel@lists.fedoraproject.or…

[PATCH 0/9] Clean up some old patches post F31
by Laura Abbott 04 Nov '19

04 Nov '19

I'd like to drop a bunch of patches Fedora has been carrying since forever. Most of these are fairly minor tweaks most people forgot we had and nobody cares about. My motivation is both in the spirit of cleaning up and also to better align Fedora + RHEL (I had a talk about this at Flock, video should be up soon). If someone wants to make an effort at upstreaming any of these, feel free to do so but I really think most of these are cruft. Thanks, Laura Laura Abbott (9): Drop namespaces config tweak Drop cpumask auto select patch Drop scsi warning patch Remove ancient ath9k workaround Drop old lis3 patch Remove some old modalias adjustments Remove old keyboard logging patch Remove patch for GCC VTA Remove crash driver Kbuild-Add-an-option-to-enable-GCC-VTA.patch | 94 --- ath9k-rx-dma-stop-check.patch | 38 - .../fedora/generic/x86/x86_64/CONFIG_NR_CPUS | 2 +- crash-driver.patch | 722 ------------------ die-floppy-die.patch | 29 - input-kill-stupid-messages.patch | 30 - kernel.spec | 20 - ...-CPUMASK_OFFSTACK-usable-without-deb.patch | 34 - lis3-improve-handling-of-null-rate.patch | 75 -- namespaces-no-expert.patch | 27 - no-pcspkr-modalias.patch | 22 - ...validate_disk-prevent-NULL-ptr-deref.patch | 39 - 12 files changed, 1 insertion(+), 1131 deletions(-) delete mode 100644 Kbuild-Add-an-option-to-enable-GCC-VTA.patch delete mode 100644 ath9k-rx-dma-stop-check.patch delete mode 100644 crash-driver.patch delete mode 100644 die-floppy-die.patch delete mode 100644 input-kill-stupid-messages.patch delete mode 100644 lib-cpumask-Make-CPUMASK_OFFSTACK-usable-without-deb.patch delete mode 100644 lis3-improve-handling-of-null-rate.patch delete mode 100644 namespaces-no-expert.patch delete mode 100644 no-pcspkr-modalias.patch delete mode 100644 scsi-sd_revalidate_disk-prevent-NULL-ptr-deref.patch -- 2.21.0

[PATCH] Enable CONFIG_DEBUG_INFO_BTF option
by Jiri Olsa 01 Nov '19

01 Nov '19

hi, please consider attached patch for fedora kernel.spec. It enables CONFIG_DEBUG_INFO_BTF options to export BTF info in /sys/kernel/btf/vmlinux file. I tested on x86_64/s390x/aarach64/ppc servers and the file /sys/kernel/btf/vmlinux shows correctly. I checked the armv7hl arch build.log and it containes the pahole execution, so I assume it's generated properly. brew: https://koji.fedoraproject.org/koji/taskinfo?taskID=38681853 thanks, jirka --- Plus adding dwarves build dependency which is needed for BTF debuginfo to be generated and attached to kernel.

New subpackages for Fedora
by Laura Abbott 28 Oct '19

28 Oct '19

Some of the downstream work I'm looking to bring back into Fedora is some new subpackages. Here's a brief explanation of what I'd like to bring in: - several packages with 'kabi' in the name. These are related to downstream ABI guarantees. All of the packages would be turned off for Fedora. No Fedora isn't getting any ABI guarantee. - ipaclones: this is related to kpatch support. This package will be turned off in Fedora. There are no plans to get kpatch support for Fedora at this time but like any feature if it makes sense to support it in the future we would consider it. - selftests: These are some bpf related selftests. This package will be turned off in Fedora. - modules-internal: Downstream wanted to designate a set of modules that get turned on but are not officially shipped. The existing design ends up building this package unconditionally so I was planning on bringing this in for Fedora. There are currently 4 modules that are designated for this package at the moment: mac80211_hwsim netdevsim pktgen rocker None of these seem like things that would be used in a regular Fedora system so I think it would be safe to move them around. I don't expect any of these changes to be particularly controversial but please let me know if you see any issue with this. I have a tree at https://pagure.io/fedora-kernel-labbott/tree/align_fedora_oct25 with everything I'd like to bring in. I've been testing and everything seems to work fine. If there are no objections, I plan to bring this in sometime next week. Thanks, Laura

Talk from Flock up and a note on some upcoming work
by Laura Abbott 21 Oct '19

21 Oct '19

If you didn't get a chance to see it, the talk I gave at Flock is up https://www.youtube.com/watch?v=kb2VS2_P6Ts . I'm linking this not for self-promotion but to give a heads up that some of the work related to this talk may start to land in Fedora. Some of the boring cleanup work will just go in but for some of the bigger pieces I'll post here to see if anyone has any objections. The goal is to eventually get a src-git that we can use as the daily driver for most of the Fedora work. When that switch over will actually happen depends on when we get a tree that meets Fedora needs. I don't want to regress Fedora or violate any packaging guidelines or make anything harder. If you have any questions, feel free to reach out to me. Thanks, Laura

How to properly PATCH F30 kernel to resolve GPU PASSTHROUGH Header Error Code 127
by Kot Begemot 20 Oct '19

20 Oct '19

Hi all, my inquiry concerns the "Building the Fedora Kernel" article (See https://fedoramagazine.org/building-fedora-kernel/, "Building the Fedora Kernel by Laura Abbot, 09/06/2019 stating that "Two common reasons to rebuild the kernel are to . . . add patches"; Also See https://docs.pagure.org/docs-fedora/building-custom-kernel.html) Specifically, I would like to apply the below-listed PATCH to kernel 5.2.18-200.fc30.x86_64 to patch to resolve a Header Error Code 127 error received when attempting GPU pass-through on a 2700X Taichi Ultimate ( PATCH: https://clbin.com/VCiYJ, patch code listed at the end). I am running the following Build: Motherboard: ASRock, X470 Taichi Ultimate BIOS Version: BIOS 3.3P CPU: AMD Ryzen 7 2700X HDDs: Host Linux: Samsung Electronics NVMe SSD Controller SM961/PM961, Windows(7/10) VMSamsung SSD 860 GPUs: Host Linux: PNY nVidia Quadro M2000, VM Pass-through: EVGA nVidia GeForce GTX 760; Linux: Fedora 30 Kernel: 5.2.18-200.fc30.x86_64). I have been through several materials including (https://unix.stackexchange.com/questions/475128/is-there-a-quick-way-to-ins… describing how to get a particular build using koji; https://docs.fedoraproject.org/en-US/quick-docs/kernel/build-custom-kernel/ describing how to build the kernel via fedpkg and git; https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-g… directed to upgrading the kernel; https://fedoraproject.org/wiki/Building_a_custom_kernel/Source_RPM describing how to build the kernel from RPMS using rpmdev-setuptree and koji; https://fedoraproject.org/wiki/Building_a_custom_kernel#Dependencies_for_bu… describing how to building the kernel via fedpkg and git; https://fedoramagazine.org/building-fedora-kernel/ describing how to build the kernel and listing two main reasons for doing so; https://docs.pagure.org/docs-fedora/building- custom-kernel.html crediting "Building the Fedora Kernel"; https://fedoramagazine.org/install-kernel-koji/ describing how to install a kernel from koji; https://github.com/AcidzDev/CentOS-header127/blob/master/CentOS-127patch.sh listing patch -p1 < pci.patch as the way to apply a patch to a kernel downloaded via wget from wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.3.1.tar.xz) I have also inquired at level1techs https://forum.level1techs.com/t/windows-10vm-gpu-passthrough-pci-header-err… and the Fedora Forum https://forums.fedoraforum.org/showthread.php?322470-F30-how-to-apply-PATCH…. At this point am somewhat overwhelemed with information and am unable to figure out how to properly apply this patch kernel 5.2.18-200.fc30.x86_64. When attempting to compile and patch using koji (instructions at https://fedoraproject.org/wiki/Build...nel/Source_RPM) I am not sure how to apply the patch because there is only the kernel.spec and source which does not have any .c or .h files. Editing the kernel.spec file and copying the patch to ~/rpmbuild/SOURCES makes the build process fail. So I am kinda stuck here. On the other hand, going the git and fedpkg route (https://docs.fedoraproject.org/en-US...custom-kernel/, https://fedoramagazine.org/building-fedora-kernel/; https://docs.pagure.org/docs-fedora/...om-kernel.html) I am not able to download a specific kernel version and always get a 5.3 kernel instead of the 5.2.18-200 that I am currently running. In fact, I tried it again yesterday and received the kernel-5.4.0-0.rc2.git2.1.fc30.x86_64.rpm. It seems that the above-listed two ways are just two similar approaches to accomplishing the same task. Either way, I just cannot get the result I am looking for: a patched 5.2.18-200.fc30.x86_64 kernel with the ability to install NVIDIA drivers, do GPU pass-through and update later via "dnf update" I must be missing something and any help is welcome.

[PATCH 0/5] Kconfig symbol cleanup for v5.4-rc1
by Paul Bolle 10 Oct '19

10 Oct '19

Here's yet another Kconfig symbol cleanup, now for v5.4-rc1. This series is - as always - boring to review and hard to test thoroughly. (I build-tested this on x86_64, but a sufficiently paranoid tester would like to build-test on other arches too. I do not have access to non-x86 hardware.) Sorry about that. Note that four symbols that were dropped in v5.4-rc1 (ie, CONFIG_ARCH_IOP13XX, CONFIG_ARCH_IOP33X, CONFIG_ARCH_KS8695, and CONFIG_ARCH_W90X900) were already removed by a recent patch by Peter. Nice! Anyhow, working on this I thought of a way to sort-of do this during regular builds. I hope to work on that before v5.5-rc1. Stay tuned!
