RaspberryPi 3 image released
by Fabian Arrotin 18 Mar '16

18 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

Self introduction - Shubham Minglani
by Shubham Minglani 14 Mar '16

14 Mar '16

Hi Community, I was learning RPM packaging in the past week and I recently got my hands on a Raspberry Pi 3 in the last CentOS Dojo here in Bangalore, India (thanks to the CentOS team). So, I would like to help with porting some packages to this platform, and will be posting the issues I run into, here and on #centos-arm, which will be a lot :) Thanks, Shubham Minglani

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

Self-introduction: Stephen Smoogen
by Stephen John Smoogen 11 Mar '16

11 Mar '16

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
