Hi, Saugata We have a problem to use the mmcblk0p8 partition, do you know if we can use it, and how can we use it? I created the 8th partition with fdisk command and the 8th partition is listed in the output of fdisk -l command but it is not listed in /proc/partitions file, even after reboot And also I can't use mkfs.vfat -n sdcard /dev/mmcblk0p8 to format. Could you give me some help about this? Thanks, Yongqin Liu

Virtual Keyboard Issue

by Bharathi Subramanian

Hi All, I am using Linaro 11.11 Gingerbread with 10" LCD and touchscreen. In that, the Android Virtual Keyboard is not visible fully on the screen. So unable to type Text in SMS or URL in Browser. Only 5mm of the keyboard's top portion alone is visible. Any clue on how to fix this issue? Is it related to IDC file? Regards, -- Bharathi Subramanian

Thank you Chengjie

by Zach Pfeffer

Hey all, Today is Chengjie's last day as a Linaro assignee. I'd like to thank him for his great work on the Linaro Android team over the last 6 months. He has had a big hand in supporting Origen and improving test automation. Chengjie is still keen on helping Linaro. He will transition to a community member, where he'll be able to help out (without being required to file status :). Its been great to have you on the team Chengjie, thanks! -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Merge tmp.perf/core branch

by Dmitry Antipov

Andrey, can we merge it into official Linaro tree(s)? This is going to mainline anyway, but there are some requests to get perf updates faster than Ingo can accept them. Dmitry -------- Original Message -------- Subject: [RFC] tmp.perf/core branch with event_name changes and some more Date: Tue, 12 Jun 2012 14:05:13 -0300 From: Arnaldo Carvalho de Melo <acme(a)ghostprotocols.net> To: Namhyung Kim <namhyung(a)gmail.com>, David Ahern <dsahern(a)gmail.com>, Jiri Olsa <jolsa(a)redhat.com>, Dmitry Antipov <dmitry.antipov(a)linaro.org> Hi guys, Could you please check out if my tmp.perf/core branch fixes the problems reported lately about event name mismatches from perf.data files collected in other machines, etc. Jiri, I made changes to how parse-events cache evsel->name, please check the cset logs to see if all is well, perf test passes at least. Namhyung, this branch also has some of your patches, please check that it is ok. Since more people are cloning from my tree, I'm trying to get used to not rebasing them, thus this tmp.perf/core attempt this time :-\ To test it, just add my remote on your local linux git repo: $ cd git/linux # or whichever name you chose $ git remote add acme git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux $ git remote update acme $ git checkout -b tmp.perf/core acme/tmp.perf/core and build the tool. Best Regards, - Arnaldo

What happened on KVM in Q1.12

by Michael Hope

Thought I'd send out an email on what progress was made on KVM last quarter. The Linaro platform and toolchain groups did quite a bit of integration work to package and polish the different components to make it quicker to get going on KVM. You can now download pre-built versions of the boot wrapper, QEMU, kernel, and root file system; use linaro-image tools to create a host and guest; and then spin both up inside a Fast Model. There's more information including versions used and links off at: https://wiki.linaro.org/WorkingGroups/ToolChain/Outputs/KVMIntegration There's still much to be done. The current focus is helping the upstream developers (Hi Christoffer!) get the patch set up into kvm-next. -- Michael

[PATCH] When building a XIP kernel, use physical memory as scratch space instead since we're probably running of a read-only medium.
