[question] CentOS 7 Installer ISO generating
by Lomovtsev, Vadim 24 May '16

24 May '16

Hi all, With the original ISO and updated kernel using VA length set to 48 bits we got an issue wit polkitd crash because of mozjs can't work with 48 bits VA. There is an open bug https://bugzilla.mozilla.org/show_bug.cgi?id=1143022 but there are not much updates. So I applied patch for mozjs, recreate rpm and tested it - works well, no crashes observed. For my setup I need to have it installed automatically at system deployment phase using installer ISO. Now every time I need to update mozjs rpm manually along with kernel rpm. I've tried to repack existing ISO with my rpms (updating packages repository) but in this case anaconda fails to proceed installation due to rpms signing checks of something like that. It looks like I need to recreate whole ISO from scratch, or properly update repodata for packages (simple createrepo is not enough) isn't it? I believe that I need to use CentOS deployed at armv8 system and use lorax to create an ISO , is that right or it could be built in cross-compiler environment? We also will need to add some extra packages for KVM support and this could help us also. WBR, Vadim

WiFi firmware
by (GalaxyMaster) 24 May '16

24 May '16

All, Is there a reason why the firmware binary for the WiFi driver is not included into the kernel-firmware package? The reason I'm asking is that initially I thought there is a licensing issue, but I've checked the license and there are no issues there. Also the same license covers the following binary we are installing: === [root@centos-rpi3 ~]# ls -l /lib/firmware/brcm/brcmfmac43455-sdio.bin -rw-r--r--. 1 root root 488193 Nov 20 2015 /lib/firmware/brcm/brcmfmac43455-sdio.bin [root@centos-rpi3 ~]# rpm -qf /lib/firmware/brcm/brcmfmac43455-sdio.bin linux-firmware-20150904-43.git6ebf5d5.el7.noarch [root@centos-rpi3 ~]# === I'll try to update the linux-firmware repository [http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tre…] with the firmware for our chip, however, I guess it would be quite a long process, so I suggest to temporarily build a sub-package (say, linux-firmware-brcmfmac43430) out of our kernel SRPM, so users would get WiFi out of the box. What do you think? -- (GM)

I know some were looking into installing a gui for the raspberry pi. I havn't found any instructions on how to do it. Is it possible, and has anyone done it? Thanks for your help. -- Seth Stevenson

Re: [Arm-dev] aarch64 internal compiler error

Glad to report; the thing that concerns me: There is no problem building a vanilla samba with (centos 7) gcc 4.85 on armv7lh nor x86_64. It fails on aarch64. I don't use the fedora sprm, that's just a simple way to reproduce. Anyway, i am sorted out.; it could very well be a personal quirck of my setup.

aarch64 internal compiler error
by Mark Verlinde 23 May '16

23 May '16

hello, To spin up a nspawn container with a vanilla samba as an ad-dc controller I had a go on compiling samba latest stable. Building a vanilla samba 4.4.3 for aarch64 does not succeed due to an internal compiler error. I know I ‘am swimming on my own here, still severe enough to share it on this list. Especially as it builds just fine on X86_64 and armv7hfp – and- succeeded to build it against Centos 7 with ggc 5.1.1 form fedora repository’s. Building on an Odriod C2 running on a “debian” 3.14.67 kernel (part of) Build log using standard gcc 4.8.5: ../source3/smbd/notify.c: In function 'change_notify_create': ../source3/smbd/notify.c:297:1: internal compiler error: in fixup_reorder_chain, at cfgrtl.c:3336 Simplest way to reproduce is building samba 4.3.0-0.1.rc4 from fedora sources: http://ftp.nluug.nl/ftp/pub/os/Linux/distr/fedora/linux/releases/23/Everyth…

Re: [Arm-dev] Silly question about expanding the root directory, wifi?

> WRT the resize of the root partition .. it is very simple to just resize > it when you write it to the sd card with fdisk as soon as you are done > on the machine where it is already mounted. I guess it depends what you're using. I tried expanding one with a live CD Gparted once and it was a disaster. I had started using it though, thinking it had already been resized. I usually don't know the right block size to use with dd so I use Win32DiskImager to write images, and I have no partition table editor for Windows. I suppose it could be unmounted safely enough but you should change the partition table before you start using it? Then again with splitfs that doesn't matter.

Maybe I missed something... LibXslt-devel?
by Ed Anderson 16 May '16

16 May '16

Ok, I'm trying to build pacemaker and all its toys. The problem is, I need libxslt-devel to get it all compiled. The problem is I can't find libxslt-devel in any of the Userland distros for amrhfp. Any leads? ideas? Thanks! -E -- Digital Mechanic

Re: [Arm-dev] Silly question about expanding the root directory, wifi?
by Alan Corey 16 May '16

I just wanted to confirm that this is a problem. I have mostly 64 and 128 GB cards but I'll rob a 32 from a camera if it might work. I've tried it about 4 times and it always panics. Last time I was connected by ssh from another box and did a cat of the instructions then copied and pasted to make sure I had it exactly right. Same thing. I'm using CentOS-Userland-7-armv7hl-Minimal-1602-RaspberryPi3.img.xz I tried taking a few pictures of the screen with a camera if it would be useful but it's probably not that hard to reproduce. So I went straight to the mailing list archives. Also it's not recognizing the built-in wifi I think, but I haven't found it in dmesg. It doesn't show in ifconfig. In some other place I read something about the /root/README giving instructions on how to download firmware for it, but it's not in the README I've got. I run a static wired LAN that's not connected to the internet. DHCP over wireless gets to a phone tether and that's the only way to the internet. I've never tried Centos before, used to run Redhat sometimes about 12 years ago. Mostly I use OpenBSD on i386, on my Pi I've also tried Raspbian, FreeBSD, NetBSD. -- Credit is the root of all evil. - AB1JX

> For wifi, I confirm that the following image > (http://mirror.centos.org/altarch/7/isos/armhfp/CentOS-Userland-7-armv7hl-Mi…) > has the /root/README file. I got it from http://buildlogs.centos.org/centos/7/isos/armhfp/CentOS-Userland-7-armv7hl-… But the /root/README is about something else. I googled and found the firmware on a Fedora site, same file names. I put the 1603 (instead of 1602) in my download queue and made a note to check there for a new version before downloading. It might be a week or so.

While discovering and mapping redistributor, we need to know +its size in advance. For the GICC case, redistributor can be in +a power-domain that is off, thus we cannot relay on GICR TYPER register. +Therefore, we get GIC version from distributor register and map 2xSZ_64K +for GICv3.
