CentOS kernel submission policy
by Vadim.Lomovtsev＠caviumnetworks.com 13 Aug '15

13 Aug '15

Hi all, We have some set of patches for our processor (Cavium Thunderx) and would like to add them to CentOS kernel for the time while they are being submitted into mainline. Is there any set policy for submitting patches to be included into CentOS kernel? And which kernel version/commit I should base my changes on? Vadim

[arm-dev] virtualization support.
by Lomovtsev, Vadim 27 Jul '15

27 Jul '15

Hi , Did anyone tried to install kvm/qemu/libvirtd onto system (e.g. yum install @virt)? I've checked repository and didn't found any virtualization related packages which are necessary accordingly to this link http://wiki.centos.org/HowTos/KVM.<http://wiki.centos.org/HowTos/KVM> Are there any plans to enable virtualization support in CentOS 7 for aarch64 ? WBR, Vadi.

armv7hl kernel updates
by Johnny Hughes 19 Jul '15

19 Jul '15

Root Build Factory is awesome for creating images and we can certainly create new images when we get new kernels .. but we need a way to make that (kernel upgrades) happen in a automated way as well. I know that some images use unique kernels, but we need a way to update the ones that use the distro kernel. I would also like to figure out how to use the distro kernel on boards that currently do not. Thanks, Johnny Hughes

CentOS Linux for AArch64 Beta2
by Jim Perrin 06 Jul '15

06 Jul '15

We are pleased to announce the second public beta release of CentOS Linux 7 for the AArch64 platform. This release contains fixes and code updates provided in the RHELSA source code recently published to git.centos.org as well as rolling previous updates into the installer. We intend to have a 'Gold' release very soon unless a blocker bugs are reported, so please test this release. Improvements since the initial Beta =================================== The 4.1rc kernel has been removed in favor of the 3.19 kernel as it contains some additional functionality by default. The 4.x kernel will be available later as a -plus kernel. Installation/Everything ISO is now available. We're currently offering an Everything ISO that can be used for usb based installation if desired. This iso is currently too large for standard DVD media, and so is best used via usb media. Many updated packages, including core packages likebzip2, dbus, grub2, libaio, and more. Download ======== The full (unsigned) install tree is available at http://buildlogs.centos.org/centos/7/os/aarch64/ Everything-ISO is available at http://buildlogs.centos.org/centos/7/isos/aarch64/CentOS-7-aarch64-Everythi… Installation ============ Installation guides and documentation will be provided via the CentOS wiki, at http://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 Update procedures for existing installations ============================================ Because the kernel version has been rolled back from 4.x to 3.19, you will need to take some additional steps to update. 1. yum -y update 2. yum distro-sync # This will roll back the installed kernel packages 3. yum remove kernel-core kernel-modules # cleans up kernel leftovers. 4. reboot to new kernel ============ Contributing The AArch64 effort is meant to be a community effort as part of the AltArch SIG (http://wiki.centos.org/SpecialInterestGroup/AltArch), and we welcome enthusiasts and vendors to contribute patches, fixes, documentation, etc. In the AArch64 Extras repository, we have provided the mock package and dependencies so that community members can more easily contribute, as well as testing their own builds locally. Please submit patches, fixes, etc to the Arm-Dev list (http://lists.centos.org/mailman/listinfo/arm-dev) for discussion and acceptance. We encourage vendors to come and join this effort, we have a loose organization focused on the alternative architectures build process and welcome interaction at the group level. Please get in touch with me (jperrin(a)centos.org) or K Singh ( kbsingh(a)centos.org ) to find out more details. The wider CentOS Ecosystem is also welcome to engage with us, both at the project and code level. If you are working with a project that interfaces, manages or develops on top of CentOS, specially in the virtualization, cloud, container and infrastructure management areas - we would love to have you guys get involved. While we don't have a lot of resources, we are working with a few vendors to build up a community resource pool that we would encourage other projects to share their development, testing and delivery around CentOS Linux for aarch64. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

ARM64 installation issue
by Lomovtsev, Vadim 04 Jul '15

04 Jul '15

Hi all, I've been trying to create installation media (usb) for CentOS 7 at arm64 based hw. I've picked up files from here http://buildlogs.centos.org/centos/7/os/aarch64/ which seems to be an installation related stuff, isn't it? So I've partitioned usb manually copy files on it and so on. System start successful, but later it falls into dracut shell with following message [ 16.061297] localhost systemd[1]: Started Show Plymouth Boot Screen. [ 16.062287] localhost systemd[1]: Started Dispatch Password Requests to Console Directory Watch. [ 16.063309] localhost systemd[1]: Starting Paths.

[ 202.948401] localhost dracut-initqueue[916]: Warning: /dev/root does not exist For some reason it fail to find /dev/root ... I didn't see any other error messages at rdsosreport log. Could anyone advise me how to fix that or point to where to read ? WBR, Vadim
