Merging AArch64 patches into Fedora
by Marcin Juszkiewicz 10 Dec '13

10 Dec '13

Hi As I have a bunch of patches to merge into Fedora I made a wiki page [1] listing all source packages I have made some patches for. But as they were mostly made against F19 I have to go through them and check are they still needed/working. If some of them are considered high priority then please let me know and I will work on them sooner than later. 1. https://fedoraproject.org/wiki/Architectures/ARM/AArch64/PatchesToMergeInto…

uboot with hyp mode support now available for the cubietruck
by Hans de Goede 10 Dec '13

10 Dec '13

Hi Richard et al, Good news for those wanting to play with hw virt on arm, there now is a u-boot with hyp support: [ 0.050980] CPU1: Booted secondary processor [ 0.051033] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001 [ 0.051181] Brought up 2 CPUs [ 0.051201] SMP: Total of 2 processors activated. [ 0.051208] CPU: All CPU(s) started in HYP mode. [ 0.051213] CPU: Virtualization extensions available. To use this, build this uboot from source: https://github.com/jwrdegoede/u-boot-sunxi/commits/sunxi-test ie: make -j4 CROSS_COMPILE=arm-linux-gnu- cubietruck_config make -j4 CROSS_COMPILE=arm-linux-gnu- sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1024 seek=8 And use it with this kernel, which removes a hack I had added to get the arch timers to work without proper uboot support: https://github.com/jwrdegoede/linux-sunxi/commits/sunxi-test2 I called it sunxi-test2 rather then re-using the old sunxi-test, so that people with an older u-boot following sunxi-test don't get bitten by needing a newer u-boot. Enjoy & Regards, Hans

You don't have instructions for how I would cross compile. Can you also start a new thread, it shouldn't have hijacked the meeting thread

Re: [fedora-arm] Booting Fedora from eMMC (BBB)

I noted something strange with the beta5 image. Even a pristine image freshly created according to the install instructions (dd, copy uboot files) doesn't actually boot from the SD card. When I press the boot switch, and power on the BBB, it hangs at "Starting kernel ...". When I don't boot from the SD card (boot switch not pressed), it boots from the eMMC, that in some way seems to chainload the kernel from the SD card, and boots it. This allowed me to boot Fedora in the first place. Any ideas anyone? Thanks, Geert

Booting Fedora from eMMC
by Geert Jansen 08 Dec '13

08 Dec '13

Hi, I tried to get F20 booting from the internal eMMC. I did as described below, but it didn't work. The result is a bricked BBB (I assume I'll be able to restore it with the 'BBB-EMMC-flasher' image but I haven't tried yet): - I installed Fedora to an SD card, and booted from it. - From within Fedora, I created a VFAT uboot filesystem and an ext4 root filesystem on the eMMC. - I copied the contents of /boot/uboot and / to the eMMC. I copied with 'tar' and made sure permissions, labels, etc are OK. - Changed the filesystem UUIDs in /etc/fstab on the eMMC. When I boot from the eMMC, the only output on the serial console is "CCCCCCCC". I can't boot from the SD card anymore either. I gives a bunch of output, and then hangs on "Starting kernel ...". The latter problem could be something I messed up myself though, not sure it is related. Any ideas what I did wrong? Is there a recommended way to get F20 on the eMMC? Regards, Geert

still do not have sata root fs bootable on wandboard quad
by Ronald 08 Dec '13

08 Dec '13

I run F20 root FS with F21 **3.12.1-2.fc21.armv7hl **kernel. (see http://www.swissdutch.ch:4999/ ) on my Wandboard quad. I cannot boot from sata, as the root FS is being mounted about 4 seconds before the sata device is ready during the fedora boot process. (And yes, I understand uSD card is needed for uboot, kernel, mouting /boot fs etc. That is perfectly acceptable - I just want the root FS and swap to be coming from Sata for obvious reasons). I try to understand the magics of Fedora boot, initramfs and the likes. It seems I need to get a PhD for this! ;-) *Question*: how do I ensure the root fs is mounted /AFTER /the sata device is ready??? Some people suggested adding a sleep command ro a dependency - my question is where and how in the initramfs do I do such a thing??? (again, when booting pointing the root fs to the sd card, the sata is working fine at the first login as seen with fdisk -l). Cheers, Ronald

Any opinions on ODROID-XU ?
by Richard W.M. Jones 07 Dec '13

07 Dec '13

If you can stand a very slow web site: http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G13751… There is apparently an unofficial Fedora 19 image which boots (http://forum.odroid.com/viewtopic.php?f=62&t=2366). I've no idea if/where they are making source available, or even if it needs patches. The hardware is interesting: - Cortex A15, hence at least the potential of virtualization support. It's not clear if there are any firmware roadblocks to this actually working. - 8 core big.LITTLE (ie. 4 x A15 + 4 x A7). Is there any support for this upstream yet? I read an article in LWN indicating it was rather complicated to support properly. - A bit low on RAM (2 GB). - A fan(!) Any opinions on this one?

That's relatively straight forward. We need a documented process to get it done. Once we have that I can sort it out with rel-eng but we would need the gcc maintainer to review/approve it. Generally what happens is that it would be built (or imported) into a side tag build. I suspect it'll be using something like a cross compiled version of ada which is then used to compile a native built version of ada which is then tagged into rawhide at which point the rest of the ada stack would be rebuilt. Ultimately it should be straight forward and easy to complete once we have the documented process. Peter
