[Call for participation] Bi-Weekly KVM/ARM Technical Sync-up

by Christoffer Dall

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

Arndale board cannont disable prefetch on

by Dai Yan

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

mailing list for cross build issues created

by Matthias Klose

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. Matthias

Panda, Android & Bluetooth

by Mike Turquette

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

Regarding full build of Ubuntu ARM with linaro toolchain

by Gaurang Shastri

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

Since vexpress_defconfig is known broken (https://bugs.launchpad.net/linaro-ci/+bug/1212893), what's the next step to move forward?

flashbench negative diff results?

by Phillip Susi

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: psusi@arafel:/usr/share/doc/flashbench$ sudo flashbench -a --blocksize=1024 /dev/sdb align 2147483648 pre 766µs on 737µs post 869µs diff -80712n align 1073741824 pre 783µs on 740µs post 850µs diff -76424n align 536870912 pre 745µs on 737µs post 852µs diff -61441n align 268435456 pre 748µs on 736µs post 846µs diff -61366n align 134217728 pre 753µs on 739µs post 852µs diff -63074n align 67108864 pre 747µs on 738µs post 849µs diff -59359n align 33554432 pre 753µs on 739µs post 850µs diff -61974n align 16777216 pre 764µs on 757µs post 866µs diff -57423n align 8388608 pre 763µs on 758µs post 861µs diff -53705n align 4194304 pre 764µs on 739µs post 847µs diff -66497n align 2097152 pre 749µs on 740µs post 856µs diff -62748n align 1048576 pre 811µs on 806µs post 902µs diff -50206n align 524288 pre 809µs on 803µs post 910µs diff -56065n align 262144 pre 810µs on 806µs post 909µs diff -53535n align 131072 pre 809µs on 801µs post 909µs diff -57797n align 65536 pre 811µs on 807µs post 908µs diff -52651n align 32768 pre 809µs on 805µs post 907µs diff -53486n align 16384 pre 808µs on 803µs post 862µs diff -31784n align 8192 pre 808µs on 800µs post 882µs diff -45365n align 4096 pre 809µs on 804µs post 803µs diff -1767ns align 2048 pre 809µs on 808µs post 807µs diff -239ns psusi@arafel:/usr/share/doc/flashbench$ sudo flashbench -a /dev/sdb align 2147483648 pre 1.35ms on 1.36ms post 1.36ms diff 3.13µs align 1073741824 pre 1.36ms on 1.35ms post 1.36ms diff -5105ns align 536870912 pre 1.35ms on 1.35ms post 1.36ms diff -3044ns align 268435456 pre 1.36ms on 1.35ms post 1.36ms diff -4602ns align 134217728 pre 1.36ms on 1.36ms post 1.35ms diff 2.73µs align 67108864 pre 1.36ms on 1.35ms post 1.36ms diff -4807ns align 33554432 pre 1.35ms on 1.36ms post 1.36ms diff 1.34µs align 16777216 pre 1.37ms on 1.36ms post 1.38ms diff -15503n align 8388608 pre 1.37ms on 1.37ms post 1.37ms diff 1.2µs align 4194304 pre 1.35ms on 1.35ms post 1.36ms diff -734ns align 2097152 pre 1.37ms on 1.36ms post 1.35ms diff -1662ns align 1048576 pre 1.37ms on 1.37ms post 1.37ms diff -2851ns align 524288 pre 1.37ms on 1.38ms post 1.37ms diff 1.69µs align 262144 pre 1.37ms on 1.37ms post 1.38ms diff 146ns align 131072 pre 1.38ms on 1.37ms post 1.37ms diff -3798ns align 65536 pre 1.38ms on 1.37ms post 1.38ms diff -2426ns align 32768 pre 1.37ms on 1.37ms post 1.37ms diff -3169ns
