Gigabyte MP30-AR0
by Gordan Bobic 05 Aug '25

05 Aug '25

Hi, I am toying with the idea of getting a Gigabyte MP30-AR0 board (despite the insanely exorbitant price tag). Has anyone got the aarch64 CentOS working on one of those? Any special instructions? Also, if I get the ISO, is it bootable on aarch64? Does the installer work? Or does the image have to be used like on 32-bit ARM? Thanks. Gordan

Kernel for BananaPi R1 (Lamobo R1)
by mo.ucina 12 May '17

12 May '17

Hello Guys, I have been compiling the Fedora 4.4.2-300 kernel for Centos , using the new Centos image for the Banana-pi . I have used the Fedora src rpm and then added the patch for the switch drivers specific for R1 (Lamobo R1) , then compiled it within the Centos dev arm environment I have . I ran into a couple of things : one cosmetic , the other one not so . Firstly the cosmetic one is that my packages came out looking like this : -rw-rw-r-- 1 user user 49332 Feb 26 07:27 kernel-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 87721969 Feb 26 07:27 kernel-4.4.2-300.LR1.el7.centos.src.rpm -rw-rw-r-- 1 user user 18785384 Feb 26 07:29 kernel-core-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 10452672 Feb 26 07:30 kernel-devel-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 1012496 Feb 26 07:27 kernel-headers-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 11844188 Feb 26 07:31 kernel-modules-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 925980 Feb 26 07:31 kernel-modules-extra-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 105452 Feb 26 07:27 kernel-tools-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 65356 Feb 26 07:27 kernel-tools-libs-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 52160 Feb 26 07:27 kernel-tools-libs-devel-4.4.2-300.LR1.el7.centos.armv7hl.rpm They all have "centos" as part of the name , which I did not expect . I did not get that when compiling in Fedora. How do you remove that ? Second observation , a one that is a bit of a concern is that , after installing the new kernel I am missing bits : user@bananapi /boot $ ls -l total 43611 drwxr-xr-x. 5 root root 1024 Feb 25 22:21 38f5ec9e217b471e8adee477d933f640 -rw-r--r--. 1 root root 171924 Nov 26 00:43 config-4.2.3-200.el7.armv7hl drwxr-xr-x. 2 root root 15360 Dec 3 14:37 dtb-4.2.3-200.el7.armv7hl drwxr-xr-x. 2 root root 1024 Dec 3 14:47 extlinux drwxr-xr-x. 2 root root 1024 Jan 1 1970 grub -rw-r--r--. 1 root root 34922581 Dec 3 14:46 initramfs-4.2.3-200.el7.armv7hl.img -rw-r--r--. 1 root root 592347 Dec 3 14:37 initrd-plymouth.img drwxr-xr-x. 3 root root 1024 Dec 3 14:44 loader drwx------. 2 root root 12288 Dec 3 14:31 lost+found -rw-------. 1 root root 2879429 Nov 26 00:43 System.map-4.2.3-200.el7.armv7hl -rwxr-xr-x. 1 root root 5866104 Nov 26 00:43 vmlinuz-4.2.3-200.el7.armv7hl I expected that I would be missing 'initramfs' as the install prog is still work-in-progress. And I was prepared to create it with dracut . However I did not expect not to be missing all the other bits such as : config , dtb, system.map, vmlinuz . I did find my new kernel it was in that dir with a hex name : user@bananapi /boot $ ls -l 38f5ec9e217b471e8adee477d933f640/* 38f5ec9e217b471e8adee477d933f640/0-rescue: total 40652 -rw-r--r--. 1 root root 35427302 Dec 3 14:43 initrd -rwxr-xr-x. 1 root root 6033128 Feb 25 22:26 linux 38f5ec9e217b471e8adee477d933f640/4.2.3-200.el7.armv7hl: total 39995 -rw-r--r--. 1 root root 34923169 Dec 3 14:40 initrd -rw-r--r--. 1 root root 5866104 Dec 3 14:44 linux 38f5ec9e217b471e8adee477d933f640/4.4.2-300.LR1.el7.centos.armv7hl: total 41061 -rw-r--r--. 1 root root 35844934 Feb 25 22:24 initrd -rw-r--r--. 1 root root 6033128 Feb 25 22:36 linux So my question is how do I go from these 2 files above , to the situation where I can boot into the new kernel 4.4.2-300.LR1.el7.centos.armv7hl . Best Regards Milorad PS Once I have verified that the switch driver works , I will post it here .

Hi, I am Interested to know more about ARM because I think it is a great piece of technology and wants to learn it by porting some RPMs to ARM (mostly RPMs related to container technology). I have a Rasberry pi 3 with me ( thanks to KB for that :) ). I have the mock setup in it ready now. However I could not find the arm config file for ARM in /etc/mock (I mean EL7 ARM config file) . Do I have to create one or we have standard config files hosted somewhere? Thanks, Lala

Announcement: CentOS 7 intermediate update to 1603 for AArch64
by Jim Perrin 29 Mar '16

29 Mar '16

This morning we released an intermediate update for AArch64/ARM64 which contains a number of fixes and improvements: Improvements ============ 1. Improved support for APM based hardware, to include network installation support for X-Gene 2 / Merlin Boards. 2. Initial support for NXP's LS2080 SoC. 3. Packaging fixes for noarch rpms, which resolves a few build system issues. 4. The cloud-init, and cloud-utils packages are now provided in the Extras repository. Upgrading ========= Simply 'yum update' as normal. A reboot will be required to take advantage of the new kernel. Downloads ========= Everything ISO: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64-Everything… sha256sum: c0a7c36af909197f35f6446d8317ae52b92c746aa5943bb11cd07fb8585b96a0 NetInstall ISO: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64-NetInstall… sha256sum: 6e71a7714100695e2d0714e01c804efc363935871c502a5793cd565ebc288aef Disk Image: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-aarch64.img.xz sha256sum: 57f5d50a58b9f4f4757858c72704e81a990e64445d3ec492e5fa50aa77181d80 Known Issues ============ 1. The centos-release package has been updated. If you are using a custom yum repository rather than the defaults, please ensure that you update your configuration with the additional gpg key information included in the new package. 2. In nearly all cases the noarch packaging change is transparent, however if you experience a conflict between two noarch packages, this can be resolved by running the 'yum distro-sync'. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

Spec for ARM side libraries
by Hugo De Zela 26 Mar '16

26 Mar '16

Hi, I haven't seen anything regarding this so here's the one I use for my systems in case it helps anyone else. It simply compiles and installs the side libraries and executables and optionally symlinks them to /usr/bin. Please go ahead and clean it up if necessary, I'm by no means a packaging expert. -H

CRDA warning message - solved
by Jan Kovalsky 22 Mar '16

22 Mar '16

Hi all, if you are seeing after boot of RPi3 a lot of messages *cfg80211: Calling CRDA to update world regulatory domain* followed then by a message *cfg80211: Exceeded CRDA call max attempts. Not calling CRDA* you might want to get rid of this warning message (as I wanted). All you have to do is to install crda package (and dependencies like iw) which provides a database of frequency bands to be used for WiFi transmissions in certain countries/regions. So just "yum install crda" and then "reboot". You should not see warnings anymore. Maybe this will help somebody. Jan

aarch64 and @buildsys-build
by Gordan Bobic 20 Mar '16

20 Mar '16

It would appear that above group isn't defined, but it is what mock uses to build a minimal development chroot. Is the omission of this group deliberate or accidental? I can add it trivially enough through a dummy repository containing nothing but a group definition, but I'm curious as to whether there is a good reason for this not being there in the first place.

RaspberryPi 3 image released
by Fabian Arrotin 17 Mar '16

17 Mar '16

Hi, In the last couple of days I was busy on various things, but got help from Henrik Andersson (thanks a lot!) about bumping/fixing the kernel we used for the CentOS 7 image. The kernel was bumped to 4.1.19 and includes now additional patch for auditd+selinux support (yay !), and that kernel will also be used for the next Rpi2 image build Auditd works fine but there is still some issues with the kernel (built from sources) from rpi and the default selinux policy, meaning that actually the image is shipped in Permissive mode only. The emdeded wifi nic works, but needs manual intervention (written in the /root/README file) as one needs to download the needed firmware for that broadcom chip. (I have a working srpm/rpm for it already, but due to license evaluation, we decided to not ship it, ut rather give instructions for people willing to do that themselves) Link to the image : http://mirror.centos.org/altarch/7/isos/armhfp/CentOS-Userland-7-armv7hl-Mi… -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

upcoming changes to the aarch64/arm64 build and yum repo files.
by Jim Perrin 16 Mar '16

16 Mar '16

I wanted to provide a bit of warning for upcoming aarch64/arm64 repository changes, as they may impact users with local mirrors. 1. I'm re-spinning the install media based on newer kernel patches I've pulled in from some vendors. This will allow the installer to support some of the newer hardware that's recently become available. 2. In order to enable the aarch64 community builder, I've had to more closely align some of the aarch64 packages with the main distribution packages. This is primarily to deal with how noarch packages are handled. The end result of this change is that the repo file will now contain two gpg keys, so if you've set up your own mirror and customized the repo file, you'll need to modify your updated file similarly. I expect to be able to release the updated tree early next week so these changes will happen reasonably soon. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

In my use case, for OpenSSL and Crypto++, its about development and validation testing for the architecture. For us, 128 GB of RAM is overkill (though I would not turn it down). The real hardware gets us out of Debian QEMU/Chroot's. We've had a few issues with the hand crafted assembly. We could not debug it because GDB was broken in the chroot. Moving to real hardware allowed us to debug the issues. We've also had troubles with -O3 and vectorization that seems to become more prevalent on real hardware. I'm also told the multimedia stuff runs a little faster under ARMv8 because of the register width and vectorization, but I generally don't use those features. ARM64 is currently a mild pain point for the beta-1 release of OpenSSL 1.1.0, and its directly because of the testing on that Hikey. See, for example, http://rt.openssl.org/Ticket/Display.html?id=4406&user=guest&pass=guest and https://rt.openssl.org/Ticket/Display.html?id=4237&user=guest&pass=guest. In short, the processes and testing ensures folks like you don't have any troubles when you use the libraries on real servers :) Jeff

Hi my name is Stephen Smoogen, and I am joining the CentOS ARM group to help on getting EPEL packages ported to this version of the OS. I have worked in CentOS back in the EL-5 days doing some QA and other work as needed. I am currently working in Fedora Project in the infrastructure group with a primary interest in EPEL. I will be ordering a RaspPi 2 (or 3 if that is what I get) to do the testing on. I will also be working on any build issues that I can. -- Stephen J Smoogen.

Epel pkgs for armhfp
by Fabian Arrotin 07 Mar '16

07 Mar '16

It's a question we receive a lot (not only this list, but also on irc, or even mails and direct discussions) but the actual status isn't really clear. It seems that something is slowly going on but hardware availability and other things have to be solved first at the epel side. (see for example this blog post about other arches in epel, and centos : http://smoogespace.blogspot.be/2016/02/epel-proposal-4-build-it-all-in-cent…) So, as some of us still need those packages, I've just created an epel-pass-1 plague target, and I just started to rebuild some of the packages. The primary goal is at least to show that it can be done, and also to help actual users who need those packages. (and all of us rebuilding the same SRPM[s] on our side is a waste of time) I haven't submitted the whole EPEL source pkgs list to the builders, but just some pkgs that I thought most people would be interested in . Pkgs (unsigned/untested) will appear here : http://armv7.dev.centos.org/repodir/epel-pass-1/ While build/root logs will appear (as usual) here : http://armv7.dev.centos.org/rpmbuild/epel-pass-1/ Willing to test ? Give feedback ? submit a list of pkgs you want to see built ? Feel free to comment -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab
