[PATCH android/toolchain/build] Fix host-libbfd installation problem caused by undefined $(INSTALL)

by Jim Huang

While executing target install-host-libbfd, the build system complains: make -C libbfd-binutils-2.20.1/bfd install \ bfdlibdir=/tmp/android-toolchain-eabi/lib bfdincludedir=/tmp/android-toolchain-eabi/include && \ -m 644 libbfd-binutils-2.20.1/intl/libintl.a \ /tmp/android-toolchain-eabi/lib && \ -m 644 libbfd-binutils-2.20.1/libiberty/libiberty.a \ /tmp/android-toolchain-eabi/lib /bin/sh: line 2: -m: command not found The problem was caused by undefined $(INSTALL). The patch attempts to configure `install' program by autotool in order to set $(INSTALL) properly and replace $(INSTALL) -m 644 with multi-platform friendly $(INSTALL_DATA).

Compiling kernel for panda linaro natty 11.05

by Amit Mahajan

Hi, I have booted panda board using 11.05 natty release of ubuntu. It worked great. Now, I am trying to compile the kernel myself. I am using the sources from tarball provided on 11.05 release page as well as from linaro git 2.6.38 tree. I have extracted the .config from running ubuntu(of 11.05 LEB) and using it to compile my own kernels. Then I am just replacing the uImage on sdcard(generated using 11.05 LEB) by my compiled kernel. Boot process goes fine till the init process but then it fails to bring on the graphics and goes to console mode. Any help on this? Below are the boot logs I see with kernel from tarball provided on 11.05 release page: Begin: Running /scripts/init-bottom ... done. init: ureadahead main process (195) terminated with status 5 fsck from util-linux-ng 2.17.2 rootfs: clean, 135614/239040 files, 433096/954752 blocks * Starting mDNS/DNS-SD daemon[ OK ] * Stopping cold plug devices[ OK ] * Stopping log initial device creation[ OK ] * Starting save udev log and update rules[ OK ] * Stopping save udev log and update rules[ OK ] fsck from util-linux-ng 2.17.2 rootfs: clean, 135614/239040 files, 433096/954752 blocks * Starting mDNS/DNS-SD daemon[ OK ] * Stopping cold plug devices[ OK ] * Stopping log initial device creation[ OK ] * Starting save udev log and update rules[ OK ] * Stopping save udev log and update rules[ OK ] * Starting AppArmor profiles Cache read/write disabled: /sys/kernel/security/apparmor/features interface file missing.

Re: LAVA Dashboard user forum

It is listed, unless I'm mistaken: http://validation.linaro.org/launch-control/dashboard/test-results/399109/ See the "Android.URL" below. > Then I'd like to see a link from a android-build.linaro.org build like: > > https://android-build.linaro.org/builds/~linaro-android/leb-panda/ This is a little bit more complex. Whatever submits the result can build an URL to the result page on the dashboard. The problem is that the android build system has no knowledge of tests. Ideally each build would trigger a test to be scheduled, results of each test should be uploaded to the dashboard. This way we could retain identity in all participating components. Thanks ZK

However, I think it'd be possible to match the prefix to an existing project when all else fails. A custom email header would be more robust but I understand that a prefix is probably easier to use.

[PATCH v7 00/11] mmc: use nonblock mmc requests to minimize latency

by Per Forlin

** Rebased and verified patchset on linux-linaro-2.6.39 ** This patchset needs this commit to be merged in linux-linaro-2.6.39 in order to apply. ------------------------------------ commit 473ba41dcc70a7977031db7fcbc5638097ca6a3a Author: Andrei Warkentin <andreiw(a)motorola.com> Date: Mon Apr 11 18:10:24 2011 -0500 mmc: card: block.c cleanup for host claim/release. ------------------------------------ How significant is the cache maintenance over head? It depends, the eMMC are much faster now compared to a few years ago and cache maintenance cost more due to multiple cache levels and speculative cache pre-fetch. In relation the cost for handling the caches have increased and is now a bottle neck dealing with fast eMMC together with DMA. The intention for introducing non-blocking mmc requests is to minimize the time between a mmc request ends and another mmc request starts. In the current implementation the MMC controller is idle when dma_map_sg and dma_unmap_sg is processing. Introducing non-blocking mmc request makes it possible to prepare the caches for next job in parallel to an active mmc request. This is done by making the issue_rw_rq() non-blocking. The increase in throughput is proportional to the time it takes to prepare (major part of preparations is dma_map_sg and dma_unmap_sg) a request and how fast the memory is. The faster the MMC/SD is the more significant the prepare request time becomes. Measurements on U5500 and Panda on eMMC and SD shows significant performance gain for large reads when running DMA mode. In the PIO case the performance is unchanged. There are two optional hooks pre_req() and post_req() that the host driver may implement in order to move work to before and after the actual mmc_request function is called. In the DMA case pre_req() may do dma_map_sg() and prepare the dma descriptor and post_req runs the dma_unmap_sg. Details on measurements from IOZone and mmc_test: https://wiki.linaro.org/WorkingGroups/Kernel/Specs/StoragePerfMMC-async-req Changes since v6: * minor update of doc for mmc_start_req and code clean up. * Indentifed a bug running tests on ext4 with discard enable. The test procedure is documented here: https://wiki.linaro.org/WorkingGroups/Kernel/Specs/StoragePerfMMC-async-req… * Resolved bug by preventing mmc async request run in parallel to discard (mmc_erase).

unable to start compiled 2.6.39-linaro-kernel for panda board

by Belisko Marek

Hello, I'm trying to build my own kernel for pandaboard based on : git://git.linaro.org/kernel/linux-linaro-2.6.39.git I use omap2plus_defconfig and enable LAN + wifi. Compile uImage, put to boot of SD card. Kernel is loaded properly but this is last message: Starting kernel ... Uncompressing Linux... done, booting the kernel. Try to enable DEBUG_LL but result is same. Is there any problem with this repo? With prebuild uImage (from ubuntu) it works fine.

device tree stuff for linaro-2.6.39

by John Rigby

Nicolas, Is device tree stuff equivalent to what was in .38 going in? I'm looking for the equivalent of what went into .38 in commit 3fb7bd037f31f5acdc213c0eb431c07a38803445 Merge branch 'devicetree/arm-linaro-2.6.38' of git://git.secretlab.ca/git/linux-2.6 into linaro-2.6.38 Thanks, John
