Fedora 27 on Banana Pi M64
by Jan Pazdziora
Hello,
I've got Banana Pi M64 on which I am able to run
2017-08-14-ubuntu-16.04-mate-desktop-beta-aarch64-bpi-m64-sd-emmc.img
from http://www.banana-pi.org/m64-download.html reasonably well,
except for failing WiFi connections to hidden SSID networks and
for kodi being unbearably slow, even the UI and mouse movements.
So seeing Ubuntu MATE not failing completely, I thought I'd give
Fedora a try. I've used
Fedora-Minimal-27-1.6.aarch64.raw.xz
Upon boot I see U-Boot (?) output and EFI lines and then row of Tuxes
and initial boot messages but then my TV goes blank. At no point during
the boot (like grub interface) do I have USB (mouse, keyboard) working.
When I add the dtb symlink to workaround
https://bugzilla.redhat.com/show_bug.cgi?id=1528575
I see wired networking and DHCP working. Upgrading kernel seems to break
the wired networking
https://bugzilla.redhat.com/show_bug.cgi?id=1528593
but with all the other packages from updates upgraded, the board still
works including wired networking and DHCP.
The initial-setup.service seems to be looping during the boot and it
seems to also affect dnf operations so I've disabled it.
Is there any opinion about how well can Banana Pi M64 be supported
by Fedora at this point, given that the board seems fine under Ubuntu
MATE but that might include some non-OSS bits that we might not want
in Fedora.
Specifically missing at this point seems to be USB support, console
after boot, and WiFi networking. Is there anything which might be useful
to try?

Re: Exactly how slow is Fedora 27 on an RP3 ? dnf update takes hours ?
by linux guy
I removed the suspect SD card from the RPi3 and tested it in my laptop.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 15750 MB in 2.00 seconds = 7893.74 MB/sec
Timing buffered disk reads: 88 MB in 3.05 seconds = 28.82 MB/sec <---
This was 365 kB/sec in the RPi3.
It seems to test OK in the laptop. Bad connection in the RPi3 ?
So I prepared a second class 10 SD card with the same image. I tested it in
the laptop that I used to prepare it.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 15908 MB in 2.00 seconds = 7973.32 MB/sec
Timing buffered disk reads: 54 MB in 3.05 seconds = 17.71 MB/sec
The second SD is actually slower to read than the first one, in the
laptop. 28.82 versus 17.71 MB/sec
I booted the 2nd SD card in the RPi3.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 816 MB in 2.00 seconds 408.21 MB/sec
Timing buffered disk reads: 66 MB in 3.03 seconds = 21.81 MB/sec <---
Faster than it was in the laptop !
#time dnf update - install 32 packages, update 275, just like last time
I ran #time dnf update and stopped it at 47 packages.
real: 30m46.181s
user: 0.00s
sys: 0m.020s
I retested the SD card and got the same read speeds as above.

Using generic tuning form armhfp
by Florian Weimer
GCC offers a generic tuning option for Arm these days, but we select
-mtune=cortex-8a instead.
Is this still a good choice?

Out of my element and out of ideas
by Luke Dary
I've been trying/struggling and failing a lot to get a working installation of Fedora Server onto a couple of SBCs and figured now is the time to ask for help. I have two NanoPi K2s (http://wiki.friendlyarm.com/wiki/index.php/NanoPi_K2) and one ASUS Tinker Board (https://www.asus.com/us/Single-Board-Computer/Tinker-Board/) that work fine with the vendor's images of debian variants, but I can't for the life of me seem to get Fedora working. I've kind of figured out that it is probably u-boot related issues that are preventing the flash of the SD cards from booting, but the random stuff I've tried from the documentation in the Wiki and from assorted places online hasn't yielded success.
I'm really hoping someone on this list can help or at least point me in a new direction, and if there are any fellow Red Hatters that work in the Tower that are willing to help I would be happy to bring the devices to work with me if hands-on would make it easier.

Fedora 28 will not have stack clash protection on armhfp
by Florian Weimer
Due to bug 1522678, we will not be able to enable
-fstack-clash-protection on armhfp.
This is unfortunate, but I don't think the lack of upstream support on
armhfp should block this feature for all other architectures (including
aarch64).
Thanks,

[Talking Points] ARM team
by Alberto Rodriguez Sanchez
Hi ARM team,
I'm Alberto from the marketing team,
Talking points are key highlights of the new release. They should be
compelling, but they will not necessarily be comprehensive. There are
different types of talking points for different types of people:
general desktop users/everyone, developers, and sysadmins. For the
Fedora 28 cycle, we will also have talking points to address some of
the Spins. They are meant to provide a short, effective answer to the
question, "What cool stuff is in the latest release of Fedora?"
Each cycle, the Marketing team compiles a short list of approximately
three talking points for each of these audiences for the upcoming
release.
So, What is new from the ARM Team side??
If you have a talking point that you feel meets the criteria found on
the talking points SOP page at
https://fedoraproject.org/wiki/Talking_points_SOP, please let us know.
Best Regards,

Play DRM content (video) on 64-bit ARM Fedora?
by Toralf Lund
Hi,
Does anyone know if it's in any way possible to play encrypted ("DRM")
HTML 5 videos on the 64-bit version of Fedora for ARM, i.e. the aarch64
version?
If I install chromium, I get a "libwidevinecdm.so" configuration in
"alternatives", which by default points to
/usr/lib64/chromium-browser/libwidevinecdm.so.fedora. I suspect that
this is just a type of place-holder, though, rather than the a real
content decryption module, and I certainly can't play encrypted videos
at https://demo.castlabs.com/.
I'm using Fedora 27 on a Raspberry Pi 3, and I've installed
"chromium-libs-media-freeworld" from RpmFusion for codec support.
Help anyone?
Related question: Is there any way I can run 32-bit software on a 64-bit
installation for ARM, in a similar manner to how I can start i686
programs on x86_64? I think I've found a "real" 32-bit
libwidevinecdm.so... I know going 32-bit all the way via the armhfp
distribution might be an option, but I've spent *a lot* of time on
setting up the aarch64 one, if you know what I'm saying.
Thanks,

"alloc_contig_range: ... PFNs busy" on aarch64
by Toralf Lund
Hi,
Another slight problem I have with aarch64 Fedora 27 on my Raspberry Pi
3, is that it spews out console messages of the form
alloc_contig_range: ... PFNs busy
Essentially, it's the same behaviour as what's described in
https://bugzilla.redhat.com/show_bug.cgi?id=1387793, but I'm seeing
different address ranges, like [30f00, 31f00), [31000, 32000) and
[31800, 32800). There are some more variants, but this morning, they all
have one of the 3 starting points indicated here.
Questions:
1. Has there been any development related to this issue?
2. Should I file another Bugzilla report - seeing as the original one
is closed with INSUFFICIENT_DATA and belongs to a different release?
3. Is there anything I can do to get around the problem, or at least
suppress the error messages? (They kind of get in my way right now
as I'm experimenting with a framebuffer application.)
Thanks,
- Toralf
