Fedora ARM 12 on IGEPv2 (Beagle Board clone)
by Matthew Wilson
Hi all,
I would like to introduce myself to the group. I have recently
received an IGEPv2 board [1], which is based on the Beagle Board, but
with wifi, bluetooth, ethernet, and more RAM. I'm still at the "wow,
it's tiny and it runs Linux" stage. I should get a bit more time over
the next month and Christmas to play around properly with it.
I'm new to embedded development, but neither new to Linux nor ARM
(writing my first ARM assembly some 15 years ago). However, for the
past 6 years I've not even built a Linux kernel, preferring to use the
default kernel in Fedora for simplicity :)
Firstly, a thank you to those involved in Fedora ARM for getting it to
this stage. If I get the time, I'd really like to contribute some
(probably small) effort to help get Fedora ARM working well on the
IGEPv2 and Beagle Board. As I progress, I'd like to know what I can
do to help.
In the meantime, I have some questions. Apologies in advance if these
seem simple.
1) There are various different kernels from different sources. I'm
used to there being a small set of "right" kernels (that is, Fedora's
idea of "right") for x86. I fully appreciate that different ARM-based
boards are quite different in capabilities (like different instruction
set variants).
a) Is there likely to be some standardised vanilla Fedora ARM kernel
source? (Or is that simply the source RPM available for Fedora?)
Then patches /could/ be offered for the more common systems (e.g.
Beagle Board & clones, SheevaPlug).
b) Would it then make sense to offer these as pre-built RPMs for common systems?
c) Is there any guidance on which version is good to use as a base?
I've seen quite different kernel versions being used (from 2.6.27 to
2.6.31).
2) I understand a little bit about the different calling conventions,
FP differences (e.g. soft FPU versus VFP), and instruction set
differences (v5 versus v7).
a) Can the kernel can be safely built with a different instruction set
targeted? (I know there are different optimisation options passed to
GCC. Apologies if this seems a bit newbie-ish.)
b) For FP-heavy programs (e.g. ogg encoding), is it possible to build
the packages with VFP/NEON but still get them to work in a soft FPU
system? I'd imagine any call to an external library would have to
somehow be defined to use a different calling standard.
3) There seem to be some missing dependencies in the packages in the
current Fedora ARM repository. For example, emacs is requiring
libotf, which doesn't seem to be there in the repository. And
likewise with the xorg-x11-font* packages needing ttmkdir. I'm
confused as to how the RPM could have been successfully built without
it. What am I missing?
4) I see there has been some discussion over unaligned data access.
(Oh, I remember that from the ARM2 days.) It seems as if the
Cortex-A8 cores allow unaligned data access when set up to do so [2].
Does this, in any way, help with the compatibility of packages
targetting Cortex-A8?
5) I've managed to get various source packages missing from the Fedora
ARM repositories to compile successfully (natively). I guess there is
a reason why there are not in the repos right now -- is that reason
down to time and priorities, or is there some blocking bugs with many
of these packages?
I look forward to being able to contribute something back into Fedora!
Kind regards,
Matthew

Fw: [PATCH 0/5] arm64, thunder: Enable Cavium Thunder SoC Family
by Robert Richter
Peter,
today I posted first enablement patches for Cavium Thunder.
See here for the thread:
https://lkml.kernel.org/r/1406732794-20920-1-git-send-email-rric@kernel.org
The patches are publicly hosted on kernel.org:
https://git.kernel.org/cgit/linux/kernel/git/rric/linux.git/?h=thunder/ma...
We will add more patches for Thunder soon.
Please take a look at the patches and consider them for integration
into the arm64 Fedora kernel. Let me know if you have questions or how
I could help adding Thunder support to Fedora.
I will also be at Flock in Prague next week. Maybe we can meet there
and start a discussion on this.
Thanks,
-Robert

This initial patches enable Cavium Thunder SoC Family. The patches add
Kconfig and devicetree support and then add Thunder to the defconfig.
The last patch is unrelated to Thunder and enables the tmpfs mount
option for a more convinient use of defconfig with distros.
The Thunder system needs more enablement patches for subsystems and
devices, this includes network, ahci, gicv3/gicv3-its, pci, smmu, kvm.
We will send separate patch sets for these. All of them base on this
initial patches.
Patches are available here:

No virtualisation in Fedora 21 on Mustang

In case you do not know yet: there is no virtualisation support
in Fedora 21 on APM Mustang. Looks like one of 3.18-rc commits

Someone interested in Pandaboard ES?
by Пламен Христов
Hello,
Recently I tried F21 on that board. The result was a bit disappointing...
Apperently Fedora has several issues with that hardware:
- thermal shutdown, after message something like "kernel trap/thermal
zone/core0"
- wlcore module error
- some other error, possibly related to swap module /Need to redo testing
here, not captured on logs/
What do You think? What is advisable to do /if any/ in this situation?
I have some time, maybe can provide ssh/vnc access, if somebody is
interested to examine issues.
However, in that case we probably have to do something with that termal
shutdown.
I'm not experienced with specific kernel things that maybe involved.
Best regards!
