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

Request for a new package: raspberrypi-vc
by Jordi Sanfeliu 13 Sep '17

13 Sep '17

Hello, Following the Fabian Arrotin recommendation, I open here the request to include the 'raspberrypi-vc' package into the CentOS 7 EPEL repository, or in the main tree. This package includes a command called 'vcgencmd' which offers a set of interesting values of the Raspberry Pi board; e.g. its temperature. Check here <http://www.elinux.org/RPI_vcgencmd_usage> for more information. I've downloaded the SRPM package from here <http://www.squeezecommunity.org/repo/fedora/24/pi/SRPMS/raspberrypi-vc-2016…>, and I realized that it was pretty easy to build on a full-updated CentOS 7 (kernel 4.4.14-v7). The following are the small modifications I made on the .spec file to accomplish it: --- raspberrypi-vc.spec 2016-07-05 23:23:13.000000000 +0200 +++ raspberrypi-vc.spec.ok 2016-07-13 12:14:39.494059817 +0200 @@ -21,12 +21,12 @@ Patch1: raspberrypi-vc-EGL-dep.patch # dtoverlay -BuildRequires: libfdt-devel >= 1.4.1-501.gitbeef80b%{?dist} +##BuildRequires: libfdt-devel >= 1.4.1-501.gitbeef80b%{?dist} Requires: libfdt >= 1.4.1-501.gitbeef80b%{?dist} BuildRequires: cmake, gcc-c++ -ExclusiveArch: armv6hl armv7hnl +ExclusiveArch: armv7hl %description Libraries, utilities and demos for the Raspberry Pi BCM2835/6 SOC GPU @@ -34,7 +34,7 @@ %package libs Summary: Libraries for accessing the Raspberry Pi GPU -Requires: %{name}-firmware >= 20150212git47bd0f0-501 +##Requires: %{name}-firmware >= 20150212git47bd0f0-501 #Provides: libEGL.so #Provides: libGLESv1_CM.so The build generated successfully the following packages: [root@rpi3 rpmbuild]# l -R RPMS/ RPMS/: total 8 drwxr-xr-x 2 root root 4096 Jul 26 15:59 armv7hl drwxr-xr-x 2 root root 4096 Jul 13 12:23 noarch RPMS/armv7hl: total 1352 -rw-r--r-- 1 root root 552156 Jul 13 12:22 raspberrypi-vc-libs-20160705-501.git0b8c195.el7.centos.armv7hl.rpm -rw-r--r-- 1 root root 340184 Jul 13 12:22 raspberrypi-vc-libs-devel-20160705-501.git0b8c195.el7.centos.armv7hl.rpm -rw-r--r-- 1 root root 244960 Jul 13 12:23 raspberrypi-vc-static-20160705-501.git0b8c195.el7.centos.armv7hl.rpm -rw-r--r-- 1 root root 241332 Jul 13 12:23 raspberrypi-vc-utils-20160705-501.git0b8c195.el7.centos.armv7hl.rpm RPMS/noarch: total 30688 -rw-r--r-- 1 root root 31420584 Jul 13 12:23 raspberrypi-vc-demo-source-20160705-501.git0b8c195.el7.centos.noarch.rpm The installation worked finely: # [root@rpi3 armv7hl]# rpm -ivh raspberrypi-vc-utils-20160705-501.git0b8c195.el7.centos.armv7hl.rpm raspberrypi-vc-libs-20160705-501.git0b8c195.el7.centos.armv7hl.rpm Preparing... ################################# [100%] Updating / installing... 1:raspberrypi-vc-libs-20160705-501.################################# [ 50%] 2:raspberrypi-vc-utils-20160705-501################################# [100%] Then a simple command to get the temperature: [root@rpi3 ~]# vcgencmd measure_temp temp=47.2'C Thanks. -- Jordi Sanfeliu FIBRANET Network Services Provider http://www.fibranet.cat

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 .

ipa-server packages
by Ente Trompete 15 Mar '17

15 Mar '17

Hi, maybe I'm wrong but IMO I have found the ipa-server packages on your arm32 repository last year (still CentOS 7.2). But now no ipa-server* package any more (CentOS 7.3) and BTW for aarch64 also only ipa-server-common-4.4.0-12.el7.centos.noarch.rpm are available. In the Fedora 25 armhfp repositories freeipa-server* v4.4.1-3 packages are offered. So I assume that it should work on ARM32 but otherwise on Fedora everything is experimental and may not work ;-). Is there any plan to build also the ipa-server* packages for ARM32 CentOS Userland Linux or must we wait for future 7.x > 7.3 there Red Hat has officail added ARM support (of course only for ARM64)? TIA, Silvio Sent with [ProtonMail](https://protonmail.com) Secure Email.

Howto build a Centos7-arm server
by Robert Moskowitz 14 Mar '17

14 Mar '17

I am, for the most part, satisfied with my basic server howto: http://medon.htt-consult.com/Centos7-armv7.html I just completed a test run through successfully. (well I would not be talking about it if it failed!) The only addition to this howto would be a button to copy a text block to the clipboard. So far, my efforts to create a multiline copy button have not been successful. There have been some recent good posts over on the postfix list that I have to review in adjusting my postfix setup. I would say my mailserver howto is 80% complete (and we know what it can take to get even 95% complete on a project!): http://medon.htt-consult.com/Centos7-mailserver.html All comments welcomed. I have my Kevlar suit on ;) Fabian, this is the best I can do as a contribution to the effort. Though I am thinking of saving a 'complete' image and write a short script to personalize it as a final step. But I really would like to figure out a way to earn a couple dollars for each use of it. :) Bob

auditd update
by Ian Pilcher 14 Mar '17

14 Mar '17

audit-2.6.5-3.el7_3.1 was recently released by upstream to fix an auditd crash when "log_format = NOLOG" is used. This update has made it to CentOS 7 x86_64, but not to ARMv7. I suspect that log_format = NOLOG is actually way more common (as a percentage) on ARM than it is on x86_64, so this is fairly ironic. Please build this update for ARMv7.

SELinux policy update breaks with outdated docker-selinux
by Gordan Bobic 09 Mar '17

09 Mar '17

Recent SELinux policy update breaks SELinux with docker-selinux < 1.10.3-57. The current version in extras repository seems to be 1.10.3-46. This breaks a lot of things, including any attempt to change the policy using semanage for anyone who has ever had docker-selinux installed on their system. Scientific Linux guys seem to be on the ball with this one, but CentOS ARM hasn't had docker-selinux updated yet even though the update has been upstream since late November. Gordan

Making an image
by Robert Moskowitz 03 Mar '17

Can I have a little help making an image via dd, and then compressing it? I want to save 'checkpoints' of my build process, so that when I have to go back, I do not have to go all the way back to the base image. I have built my basic image (I will be updating my howto, found a few bugs), and fdisk reports: Disk /dev/sda: 120.0 GB, 120034124288 bytes, 234441649 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x0000c89d Device Boot Start End Blocks Id System /dev/sda1 2048 1026047 512000 83 Linux /dev/sda2 1026048 2074623 524288 82 Linux swap / Solaris /dev/sda3 2074624 6268927 2097152 83 Linux Obviously, I do not want to dd the whole 120GB, as I am still only using 4GB, though I will probably have to enlarge sda3 a bit to hold all the software I need. I did this a couple years back, but can't find my notes. :( thanks

Given that we are working on server OS for little boards that work will with little drives: For longtime operation of a server which is better, A notebook 2.5" hard drive or A notebook 2.5" SSD drive ? Both pull 1A, so no power advantage. Which can be expected to run for 2 - 3 years straight? (Note: I am looking at this Kingston 240GB ssdNOW 300 that I pulled from a notebook that had to be upgraded to a 480GB SSD) thanks
