Hi, As discussed at UDS/LDS, there is a very good chance that the next Linaro release will be based on kernel version 2.6.38. What that means is that we still have 4-6 weeks to get some code into various maintainer trees before the 2.6.38 merge window opens in early January. If you are working on consolidation of some feature across SoCs, it might be nice to get this code in before then so that we don't have to backport patches for the release. /Amit

[RFC 0/2] Selective identity mapping for kexec

by Per Fransson

Hi, I would appreciate your input on some kexec related changes. When restarting using the kernel kexec functionality the MMU needs to be turned off. Any code which does this needs to use identity mapped addresses to get reliable results. In the ARM kexec case this identity mapping is done: - using the page table of the current task - for all addresses normally used by user space, i.e. 0x00000000-PAGE_OFFSET If kexec is used at a kernel crash to collect a core dump this means that we lose important information. This is what these patches do: * Actually turn off the MMU, which has been omitted by mistake, see this post: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-July/019631.html * Set up a more selective identity mapping * Restore the old mapping once the MMU is off The patch was generated from a linux-next 20101028 with these additional related patches which are in the pipeline: http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=ae360a7… http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=2fd8658… http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=commit;h=ae69480… Regards, Per Per Fransson (2): Turn off MMU in cpu_v7_reset Selective MMU identity mapping for kexec arch/arm/kernel/machine_kexec.c | 27 +++++++++++++++++++++- arch/arm/kernel/relocate_kernel.S | 23 +++++++++++++++++++ arch/arm/mm/mmu.c | 44 +++++++++++++++++++++++++++++++++++++ arch/arm/mm/proc-v7.S | 4 +++ 4 files changed, 97 insertions(+), 1 deletions(-) -- 1.7.2.2

[PATCH] mx51evk: Fix 2 hours reset issue

by Shawn.Guo＠freescale.com

From: Shawn Guo <shawn.gsc(a)gmail.com> The mx51evk u-boot has an issue that system will get reset every 2 hours. MC13892 has an inside charge timer which expires in 120 minutes. If ICHRG and CHGAUTOB are not set properly, this timer expiration will get system power recycled. Since mx51evk has no Li-Ion battery on board, the patch sets ICHRG in externally powered mode and sets CHGAUTOB bit to avoid automatic charging, so that system will not get reset by this timer expiration. The patch also corrects the bit field definition of register 48 (Charger 0) per latest MC13892 Reference Manual.

maverick-proposed queue freeze

by Jamie Bennett

Hi, According to the Linaro release process [1] the maverick-proposed queue will be frozen tomorrow. After this date no uploads should be accepted for -proposed until the queue unfreezes on 8th November 2010 without consultation with the Linaro release team [2]. The total freeze time will be 12 days. The freeze process was agreed at the platform sprint in Prague and has benefits for both Ubuntu and Linaro. This period should be used to flush the -proposed queue, testing, verifying and promoting to maverick-updates what is currently there. If you have an update that really must be added to the queue in the next 12 days please email the team[3] for feedback. The Linaro Release Candidate images will be created on the 1st November and the images will be verified until Final Release on the 10th November. With your help we can get the -proposed queue flushed and produce rock-solid Linaro images, carrying the great work Ubuntu has done to more ARM based platforms. Regards, Jamie. -- Linaro Release Manager [1] http://wiki.linaro.org/Process/Cycle/PostUbuntuReleaseProcess [2] http://www.launchpad.net/~linaro-release [3] linaro-release(a)lists.launchpad.net

DVI /S Video issues in linaro-m-netbook-efl-tar-20101024-0.tar.gz with Beagle Board XM Rev A3

by Manjunath Singh

Dear All, Looks like something is broken in the new kernel ( Post changes to the bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663642 ), In the earlier versions of the kernel atleast the S- Video used to work ( tested in Maveric 2.6.35.6-l5 Regular/Non netbook edition ). Now If I pass omapfb.mode=tv:pal omapfb.default_disp=tv .. the xorg exits with with /dev/fb0 no such file or directory ( and ls -l on /dev/fb* confirms there is no files by that name ), I tried omapfb.mode=lcd:640x480 ( and other resolutions ), the X server starts but No out put on the screen / LCD tv thorugh S Video. The DVI port with default options ( and tried with different resolutions as well ) connected through HDMI cable to the TV No output on the display in any Distributions/OS/Kernel I have tried sofar. I understand that Fixing DVI might take some time because there is a HW change in Beagel Board XM A3, However I I would really appreciate if some one point me how to get atleast S Video output till HDMI starts working again. Thanks -- Regards, Manjunath --------------------------------- Miles to go before I sleep... ----------------------------------

Linaro@UDS: dining opportunities out of the hotel

by Steve Langasek

Hey all, If you're like me, you're sitting here at the end of the last session of the day feeling peckish and wondering what's for dinner. Which made me realize that there was no information in the Linaro wiki page about the dinner options here at Linaro@UDS. Sorry about that - let's correct that now! Outside of the Wednesday organized dinner, engineers are free to make their own dinner plans - either here at the hotel, or in town. If you want to have dinner in town, buses are available each evening to take you back and forth to one of several points in and around Orlando that are reasonably central to dining opportunities. I've posted the bus schedule here: https://wiki.linaro.org/Events/2010-10-LDS#Evening%20buses Our local experts have provided us a list of recommended restaurants, available here: https://wiki.ubuntu.com/UDS-N?action=AttachFile&do=view&target=List+of+Rest… Bon appetit, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
