Gigabyte MP30-AR0
by Gordan Bobic 12 Nov '19

12 Nov '19

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 problems on APM X-Gene
by Gordan Bobic 29 Jan '18

29 Jan '18

Apologies for taking so long to return to this thread, it took way longer than expected to get to the machine and get it up and running again. I also just updated the build to the latest 4.9.60. Here is a download link to both binaries and src.rpm (download the kernel tarball from kernel.org manually to build from src.rpm): http://ftp.redsleeve.org/pub/misc/kernel/aarch64/RPMS/ http://ftp.redsleeve.org/pub/misc/kernel/aarch64/SRPMS/ To recap - I am also running with Tianocore EFI chain-loaded from u-boot, and mainling 4.9.x boots just fine on it. No need for disabling ACPI on the kernel command line, no need to run EFI firmware as a 1st stage boot loader, it just works. Do feel free to try it - if that works for you but the distro supplied 4.5.x kernel doesn't, it seems reasonably conclusive that it is the CentOS kernel that is broken for this board. I'd also be interested in learning whether you have any luck getting PCIe cards to work with it without problems - I haven't tried it since upgrading to 4.9.x, but certainly on 4.4.x mainline the machine used to reliably lock up as soon as the driver for the PCIe card loads.

Howdy Y'all, Where would be a few good places to start with the Pine64? My Wife bought it for me with the initial crowd-funding and I am just now getting to playing with it. Any good Centos / Ubuntu images? -- Peace and God Bless, - Dan. ######################## DevOps on a Starship: vim /cookbooks/hyperdrive/attributes/alignments.conf git add . commit -m 'Automation is the new Magick.' git push knife cookbook upload hyperdrive

[Question] CentOS7.4 for ARM update plan
by Zhou Wang 27 Nov '17

27 Nov '17

Hi, I am afraid in the right place to ask this question. Redhat7.4 for ARM64 already released: https://access.redhat.com/articles/3158541 Before this, CentOS7.4 for ARM64 released: https://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 As CentOS7.4 just took one internal version of Redhat7.4 as its release version, we should at least backport patches after above Redhat7.4 internal version to CentOS7.4. My question is that is there a plan to backport these patches to CentOS7.4? Or where can I find such plan/schedule? Thanks a lot for any help, Zhou

Introducing 2017’s extensions to the Arm Architecture
by Jeffrey Walton 27 Nov '17

In case it did not make your radar: https://community.arm.com/processors/b/blog/posts/introducing-2017s-extensi… It looks like ARMv8.4 will also provide hardware support for China's SM3 (hash) and SM4 (block cipher), like they support SHA and AES. Jeff

fake-hwclock
by Kristján Valur Jónsson 21 Nov '17

21 Nov '17

Hi there. I'm running CentOS7 on an RPi3 without hardware clock. I found no suitable "fake-hwclock" (as avilable for raspbian) on the internet, so I implemented my own systemd unit for that. Check out https://github.com/kristjanvalur/fake-hwclock if you're interested. Cheers! -- Kv, Kristján Valur Jónsson, RVX
