new Linaro kernel branch available: linux-linaro-2.6.36

by Nicolas Pitre

Now that the Linaro release is shipping with a 2.6.35 kernel, we need to move forward. I therefore created a linux-linaro-2.6.36 tree which contains the v2.6.36 core code but with the latest ARM specific pieces from mainline. This branch is meant to be stable i.e. it won't be rebased, and only patches believed to be in a state ready for mainline inclusion should be merged in that tree. That should provide a more recent basis for people wanting to forward port their work but who are not comfy with a -rc kernel. Of course this didn't get any significant level of testing yet. Please report any issue you may have with it. Nicolas

Linaro 10.11 Final released

by Jamie Bennett

Hi, The Linaro team is pleased to announce the release of Linaro 10.11. 10.11 is the first public release that brings together the huge amount of engineering effort that has occurred within Linaro over the past 6 months. In addition to officially supporting the TI OMAP3 (Beagle Board and Beagle Board XM) and ARM Versatile Express platforms, the images have been tested and verified on a total of 7 different platforms including TI OMAP4 Panda Board, IGEPv2, Freescale iMX51 and ST-E U8500. The advances that have happened in this cycle are numerous but include a completely rebuilt archive using GCC 4.4.4 and the latest ARM optimised tool chain, the Linux kernel version 2.6.35, support for cross-compiling, a new hardware pack way of building images, 3D acceleration improvements, u-boot enhancements and initial device tree support, a new QA tracking structure, the list goes on. For a full break-down of what was scheduled for the 10.11 release please see: http://wiki.linaro.org/Releases/1011/Blueprints Thanks to everyone involved who made this happen. Here's looking forward to a sucessful 11.05 release. To get Linaro 10.11 ------------------- The 10.11 release can be found at: http://releases.linaro.org/platform/linaro-m/headless/final/ and when combined with a hwpack from: http://releases.linaro.org/platform/linaro-m/hwpacks/final/ using the instructions from: http://wiki.linaro.org/Releases/MilestoneBuilds a installable image is produced. For any errata issues please see: http://wiki.linaro.org/Releases/1011/Final#Issues Bug reports for this release should be filed in Launchpad against the individual packages that are affected, if a suitable package cannot be identified, feel free to assign them to: http://www.launchpad.net/linaro The team has also produced 3 other non-supported images as part of a community effort, they are: * ALIP * http://releases.linaro.org/platform/linaro-m/alip/final/ * EFL based netbook * http://releases.linaro.org/platform/linaro-m/netbook/final/ * KDE based plasma handset * http://releases.linaro.org/platform/linaro-m/plasma/final/ These need to be combined with a hardware pack as above. Next Steps ---------- Engineering effort has already started on the 11.05 cycle.

Re: Call for testing: Linaro 10.11 FINAL

by Paul Larson

The size correction in lmc happens at the end, so my best guess is that it's a qemu issue. Id put a bug in against that, and we should probably release note it as well. -Paul Larson On Nov 9, 2010 6:58 PM, "john stultz" <johnstul(a)us.ibm.com> wrote: On Tue, 2010-11-09 at 17:47 -0600, Paul Larson wrote: > On Tue, Nov 9, 2010 at 5:12 PM, john stultz ...

I've just gone back testing older images and hwpacks I've used in the past and am seeing the same issue there, so it does seem like its connected to the linaro-media-create scripts. Here's the command I'm using, just as listed on the wiki: #linaro-media-create --image_file beagle_sd.img --image_size 4G --swap_file 200 --dev beagle --binary linaro-images/linaro-m-headless-tar-20101108-2.tar.gz --hwpack linaro-images/hwpack_linaro-omap3_20101109-1_armel_supported.tar.gz Per our irc discussion, I tried reproducing this by omitting the "--image_size 4G" portion, and indeed it seems that worked and the resulting image boots fine. Similarly it works fine using 8G. Something just seems off using 4G. Looking at linaro-media-create to see if I can narrow anything down. thanks -john

nano-headless

by Tom Gall

I've put a little time into generating a hyper small footprint linaro headless image. From UDS the two sizes to try and fit into as I understand are 64M and 128M installed. So with that in mind, via live helper I created a headless image where none of the recommended packages were installed. This brings the installed size of the root fs down to 165Meg installed (excluding hwpacks) With a little script-foo which I've created to be part of the live-helper build I can get the rootfs installed size down to 82,240,000. This is without turning to the usual things to slim things down like busybox as well as without going through /bin /sbin /usr/bin /usr/lib /lib and pulling out specific function that isn't needed. What I have done is gone after the low hanging fruit. That is i18n locales, documentation, zoneinfo, charmaps and some X11 & firefox things that obviously aren't needed since those things aren't installed in headless anyway. All of that gets us down to `125Meg. To get the next approx 40Meg I have to take out /var/lib/dpkg and /var/lib/apt. This could make a certain amount of sense for a demo system running on out NAND flash. This is somewhat problematic however in so much if you want to use linaro-media-create with hwpacks, well you need apt to work and that comes with the as mentioned 40 Meg price tag. Anyway this seemed to be a good Friday night over a beverage type of hack to gain a little data just to see the effort required. All in all I do think this is a reasonable approach to get to a "nano" sized system that would fit into flash. To get that last mile tho, I think we'd need to turn to busybox, audit the libs and binaries, adjust the kernel build such that modules are kept to a minimum and only function actually needed is built in the kernel as well as working out the last bit of install via something linaro-media-create-like so that one could at least get things onto an SD card without too much hackery for test yet not gain the full 123 meg noted below.

Pull request for OMAP3/4 fixes

by Anand Gadiyar

Hi all, The following patches are a bunch of OMAP-related fixes. In summary these patches: - allow omap3_defconfig and omap_4430sdp_defconfig to build and boot - get MMC (somewhat) working on Panda board - fix a bug that caused all 3630s to be reported as ES1.2 (highly unlikely that these are available in the wild) Except for Catalin's patch, all of them were cherry-picked from mainline. I hope I'm not too late to get these merged. - Anand The following changes since commit c121be8626744d7dc81ed7b37e1f744fd2db8a78: Nicolas Pitre (1): Revert "Revert "Versatile Express: add support for local timers on CA9X4 daughterboard"" are available in the git repository at: git://dev.omapzoom.org/pub/scm/anand/linux-omap-usb.git omap-fixes-for-linaro Anand Gadiyar (1): USB: musb: Kill board specific pinmux from driver file Benoit Cousson (1): omap4 hsmmc: Fix the init if CONFIG_MMC_OMAP_HS is not set Catalin Marinas (1): ARM: Do not enable SWP emulation if CPU_V6 && CPU_V7 David Anders (1): omap4: pandaboard: Fix the init if CONFIG_MMC_OMAP_HS is not set Madhusudhan Chikkature (1): OMAP4 ES2: HSMMC soft reset change Menon, Nishanth (1): omap4: pandaboard: fix up mmc card detect logic Nishanth Menon (1): omap3: id: fix 3630 rev detection Tony Lindgren (2): omap: Use CONFIG_SMP for test_for_ipi and test_for_ltirq omap: Fix sev instruction usage for multi-omap kishore kadiyala (1): mfd: Adding twl6030 mmc card detect support for MMC1 arch/arm/mach-omap2/Makefile | 1 + arch/arm/mach-omap2/board-4430sdp.c | 15 ++++- arch/arm/mach-omap2/board-omap4panda.c | 24 +++++++- arch/arm/mach-omap2/hsmmc.c | 3 + arch/arm/mach-omap2/id.c | 2 +- arch/arm/mach-omap2/include/mach/entry-macro.S | 6 +- arch/arm/mach-omap2/omap-smp.c | 3 +- arch/arm/mm/Kconfig | 2 +- arch/arm/plat-omap/include/plat/mmc.h | 1 + arch/arm/plat-omap/include/plat/smp.h | 7 -- drivers/mfd/twl6030-irq.c | 73 ++++++++++++++++++++++++ drivers/mmc/host/omap_hsmmc.c | 15 ++++- drivers/usb/musb/omap2430.c | 6 -- include/linux/i2c/twl.h | 31 ++++++++++ 14 files changed, 162 insertions(+), 27 deletions(-)
