Hi all,
Linaro is going to host a bi-weekly sync-up call for technical issues on
KVM/ARM development. The KVM 32-bit and 64-bit maintainers as well as
the QEMU ARM maintainer will typically be on the call.
The first call will be held Tuesday August 27th.
If you, your organization, or any of your colleagues are interested in
attending this call, please reply back to me with:
- Your name
- Your e-mail address
- The capacity in which you are interested (hobbyist, company you
represent, ...)
We will send out an invite after we have collected all the participants.
The calls will be based on an agenda that I will E-mail out to the list
the Monday before the call. If we have no items on the agenda, we will
not be having the call. Agenda items should be E-mailed to me and/or
the kvmarm list before the call, obviously before the Monday prior to
the call.
We emphasize that this is going to be a technical call for engineers and
not a forum to solicit services or discuss business concepts.
Best,
-Christoffer
Dear All,
Actually I have sent a mail previously, but I found more info for my issue.
So I am sorry that I that I send mails again,
In fact, I found that when I call " MCR p15, 1, %0, c15, c0", 3, I am
trapped into unsecured mode.
And I think that I have to call secure monitor(SMC) to do prefetch off
safely.
But I found that I cannot get the public interface to do that.
Could someone give me a hand?
Platform:
1) linaro ubuntu 13.07
2) arndale board
3) No Virtualization enabled
Best Regards
Dai Yan
Today the debian-cross(a)lists.debian.org ML was created. The rationale for
having such a ML can be found in http://bugs.debian.org/717332. The description
for the ML currently is:
Discuss cross building of packages and infrastructure for cross-builds
The list discusses
* How to cross-build packages within Debian
* Infrastructure needed to cross-build packages. This may include
discussion about additional tags for cross-building, running
cross-build daemons, etc.
* How to use cross-builds to bootstrap Debian ports.
The issue for the creation of this ML explicitly includes topics which affect
Ubuntu and other derivatives. So it makes sense for Ubuntu and Linaro
developers to subscribe to this ML too. Please avoid cross posting to Ubuntu a
and Linaro lists, as people subscribed to debian-cross may not be allowed to
post to these lists.
Please subscribe to this list if you are interested in cross build issues.

Hi all,
I'm interested in looking at some Bluetooth stuff on my OMAP 4460
Panda ES. Looking at the bug reports I don't see any Jelly Bean
releases that have BT working properly on Panda. Is this correct?
Can you please point me to a release where BT and display/hdmi are
working for Panda? It's OK if it is ICS.
I'm OK starting with binaries but I would much prefer to be able to
build from source and reproduce any known-good bins. I have already
built JB from the latest tip as well as the 13.07 manifest (display is
working fine but BT doesn't work, bugs already filed). I tried the
12.07 Panda LEB (which I think was the last ICS release?) but the
binaries supplied did not have display working even after running the
install-binaries-4.0.4.sh script.
Thanks,
Mike
Hi,
I don’t know I am in right channel to ask this question, if not then please
guide me.
Currently, I am following
https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/UsingXdeb for
cross compiling using xdeb. I am using “raring” as a Ubuntu distribution.
So using above link, up to the section “Kick a build of grep and
build-deps”, everything goes perfectly.
But, this shows how to build any single package like grep, libpng, etc..
If I want to build (cross-compile) all the “raring” Ubuntu Distribution
package as one shot, how can I do??
Is there any tools available for cross compiling all packages ?? How can I
setup auto builder machine??
Please guide me as I am stuck in doing single package one by one.
Regards,
Gaurang Shastri

For the kernel CI, we build all the defconfigs and boot test on
available platforms in LAVA lab.
Since vexpress_defconfig is known broken
(https://bugs.launchpad.net/linaro-ci/+bug/1212893),
what's the next step to move forward?
I'm trying to use flashbench to characterize a Kingston 8 GB data
traveler USB flash drive I have and am getting strange results. Could
someone help me understand how the diff can be negative? It seems that
the drive reads faster when crossing almost all boundaries rather than
slower:
