Gigabyte MP30-AR0
by Gordan Bobic 09 Oct '24

09 Oct '24

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

CentOS 7.4.1708 rebuild status
by Fabian Arrotin 08 Sep '17

08 Sep '17

Hi guys, You're probably aware that upstream RHEL 7.4 was released last week, so the x86_64 rebuild started in the following days (https://seven.centos.org/2017/08/centos-linux-7-1708-based-on-rhel-7-4-sour…) On the armv7hl/armhfp side I started (as usual) to rebuild gcc, wait (long time), then glibc. Those rebuilds finished on saturday morning, so since that day, the armhfp builders have been busy rebuilding the 700+ SRPMs. At this stage, more than 530 pkgs were already rebuilt (https://armv7.dev.centos.org/built.html), and some are excluded as not covered for armhfp, which is always expected But this time, we have packages that have failures where they were able to build fine, or other new issues. Example of package failing now to build is mariadb : it builds, but it fails at the tests stage in mariadb itself, so we'll probably need to verify what/why/how Other new "interesting" issue is that some pkg are now relying on external BuildRequires, like devtools-6 package set. As Johnny explained it in his blog post for x86_64, it was built for x86_64, so there is no issue at all. But on the armhfp side, it wasn't, and worse, it will not work : https://armv7.dev.centos.org/rpmbuild/c71708-pass-1/19769-devtoolset-6-gcc-… => "*** Configuration armv7hl-redhat-linux-gnu7E not supported" Any help on trying to solve those issues is welcome PS : myself being busy on my SysAdmin job, so not having a lot of time to spend on armhfp, and also diving into "Summer Holidays without internet connectivity" mode soon ... -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

Hi Does someone use a bananapi on centos ? I'm using it for a long time, and I'm still on 4.2 kernel. Every time I try to install a newer I got a lot of errors during install, or yum get stuck on "cleaning..". The last time I success to install it, it's not very stable... So if someone got feedback, or feedback about any card on an uptodate kernel ? Thanks Nicolas

How does OpenSSL work on ARM?

The INSTALL document talks about the no-asm configuration option. Details about what the assembler code does in terms of optimization are only available by reading the source code comments in the various Perl files that generate the assembler, mostly. On x86, the assembly code uses the CPUID instruction (see the OPENSSL_ia32cap.pod manpage) to determine if various instructions (AES, SSE, MMX, etc) are available and will use them if so. For other processors, similar tests are performed if at all possible.

Does any user/application always pick classic implementation for AES operation regardless of AES-NI improves speed much? Is there any document about this interface selection? Thanks, Jinsong

Hi All, I am quite new to CentOS. I have a small project to make CentOS running on iMX.6 quad so I want to ask if anyone could hint me to some documents or guidelines to get start with it ? It seems CentOS use its own build system (not similar to Yocto). Any recommendations are highly appreciated. Thanks -- Quan Cao 0976574864

Hi team, Is it possible to you to share your mock configuration you're using to compile packages for centos ? It can allow us to compile some needed packages ourself (maybe more faster than using rpmbuild). Are you compiling all packages on arm processors or with cross compilation on x86? thanks

Proposal regarding aarch64 images
by Jon Nettleton 01 Aug '17

01 Aug '17

Now that SolidRun is ramping up our Armada 8040 line I have had more initiative to start testing various distros. There is an active effort to bring full UEFI support to the 8040 platforms however this is still a WIP. In the meantime I was looking into u-boot's efi loader and currently there is major hurdle with using this boot method on the CentOS images...the /boot partition is formatted as xfs. Of course it would be easy enough to spin a new image with /boot formatted as ext4. Is there any reason not to make the default images use this configuration? This would obviously be one less hurdle for using CentOS aarch64 on more platforms. Thanks, Jon
