[PATCH] omap4.conf: Disable OMAP2 support

by Peter Ujfalusi

When the kernel is built with CONFIG_ARCH_OMAP2 it will select CPU_V6 and other dependencies which causes issues in user space. For example when clients try to connect to PulseAudio they will crash with: Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting. Remove support for OMAP2 for now. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Hi Andrey, Can you take a look at this patch? In the latest hwpack for panda (with 3.9 kernel) PulseAudio clients all asserts with the following error: Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting. The same userspace works fine (well, mostly) with 3.8 based hwpacks. It turns out that this is cased by the CONFIG_ARCH_OMAP2, if we disable it PA clients no longer assert. Since the config in question is for OMAP4, I see no issue removing the OMAP2 support since in this way we can get PA working. One issue still remain with PA: None of float resample method works: speex-float-[0-10] However speex-fixed-[0-10] and ffmpeg seams to be working, but it is not perfect. I'll try to figure out why we have this failure since on my Gentoo FS all resample method works fine with the same kernel.

Linaro Virtualization Team's Weekly Report - Weeks 13/14 2013 ============================================================= During the last 2 weeks (27 March - 10 April 2013) the team has been working on the following areas. More detailed information can be found on the meeting reports wiki page [0]. Ongoing work ------------ * BOOTLOADER HYP MODE SUPPORT FOR ARMv7 [1] by Andre Przywara * rebase existing Versatile Express patches against upstream u-boot [2] Done: - Reworked patch for Versatile Express to be more reusable for other boards. - U-Boot patch sent as RFC, waiting for reaction. * implement HYP command to let u-boot switch into HYP mode [3] Done: - HYP mode switch works reliably. - SMP is working too. - VExpress patches sent upstream (V3 of the patch set). - discovered a bug in Linux 3.9-rc: - DMA refactoring broke Versatile Express: NULL pointer exception. - Patches already are on ML, but not yet in HEAD (3.9rc5-77) - discovered related issue with DMA PL330 on Highbank (Rob@Calxeda seems to care about this) * ARMv7 KVM GUEST MIGRATION [4] by Peter Maydell and Andre Przywara * QEMU: audit the vexpress model for devices we use which do not currently have migration support [5] by Peter Maydell Done: - task completed. - patches now preliminarily queued in arm-devs.next, though if there is a late-breaking issue with one of them it will have to be fixed and patches updated. * QEMU: implement full cp15 sync with kernel [6] by Peter Maydell Done: - Some work that was assumed to be already committed last year appeared to be still pending - hew sub-task created: QEMU: move CPU migration to vmstate [7] Working on: - pending for [7] to complete. * QEMU: move CPU migration to vmstate [7] Done: - updated patches from Juan Quintela from last year which are updating the migration state for the CPU itself to use VMState structures. Working on: - testing and tweaking of the updated patches. * kernel: agree on a data structure to describe timer state [8] by Andre Przywara Working on: - reading documentation. - thinking about code structure. - timer migration prototype. * ARMv8 KVM QEMU prototype [9] * Add skeleton ARM64 build patches to local tree [10] Done: - completed this sub-task. * Add arm64 mach-virt system model skeleton [11] Working on: - only has serial, can add virtio stuff later. - in progress. * Add creating FDT from scratch to mach-virt system model [12] Working on: - in progress, nearly done. * Add kvm guest creation and launching of armv8/mach-virt [13] Working on: - in progress, just started. * IN KERNEL SUPPORT FOR KVM ARMv8 [14] by Anup Patel and Pranavkumar Sawargaonkar, Geoff Levand Done: - KVM ARMv8 patch set review, fixes suggested (by Geoff). - Initial patch set for APM board bring up is reviewed internally in APM and is queued for upstreaming in near future. - real AMRv8 hardware is accessible to Anup and Pranav - switched to it for further work. - ARMv8 kernel is bootable on the board now. - U-Boot is starting the kernel in HYP mode on the board now. Working on: - Debugging the guest part now (on the board). Currently it is not booting (still in early debug). - Hacky early printk support in kvmtool is to be properly submitted to the ML as an RFC. * CI BRING UP: KVM ARMv7 [15] by Riku Voipio Done: - Find out howto include guest image in host image. - Create ci.linaro.org jobs for submitting validation tests to LAVA for VE TC2. Working on: - Create ci.linaro.org jobs for submitting validation tests to LAVA for Arndale.

Fwd: Ubuntu (USE_INITRD) on FastModels VE Cortex A15 RTSM

by Fathi Boudra

---------- Forwarded message ---------- From: Zongwei Zhou Date: 11 April 2013 04:47 Subject: Ubuntu (USE_INITRD) on FastModels VE Cortex A15 RTSM Dear Linaro maintainers, My name is Zongwei Zhou. I am a Ph.D. student at Carnegie Mellon. These days I came across one problem when booting Linaro Ubuntu on FastModels VE Cortex A15 RTSM. I would greatly appreciate it if you could offer some guidelines and suggestions. Thanks very much! By following the guidelines in https://releases.linaro.org/13.02/ubuntu/vexpress "RTSM" tab, I have successfully booted Ubuntu. However, the booting process is quite slow in FastModels simulator. When looking at the booting log, I found out that it stuck quite a long time in loading file system from RTSM MMC. Thus I am looking for using initrd to speed up the booting process. I downloaded the linaro boot-wrapper source code and found out that it supports USE_INITRD configuration. USE_INITRD allows me to combine the boot-wrapper, kernel image and filesystem.cpio.gz into a linux-system.axf. I did that, but it seems that the boot-wrapper runs correctly, but linux kernel later stuck in an infinite loop at address 0xC0253970, and even the FastModels terminal is not invoked. The kernel image I am using is the uImage from hwpack_linaro-vexpress_20130224-256_armhf_supported.tar.gz. The way I created the filesystem.cpio.gz is I decompressed the linaro-quantal-nano-20130224-286.tar.gz tar ball, and repacked it as compressed cpio archive using "find . | cpio --quiet -H newc -o | gzip -9 -n > filesystem.cpio.gz". Could you please kindly give me some hints about booting Ubuntu with initrd? Or are there other alternatives that could speed up the booting process? I am trying the NFS boot now. Thanks very much for your patience about this long email. Looking forward to hearing back from you. Best wishes, Zongwei Zhou -- Zongwei (Stephen) Zhou （周宗伟 in Chinese） Electrical and Computer Engineering Department, Carnegie Mellon University, Pittsburgh, PA 15213 Email: zongweiz(a)andrew.cmu.edu

staging.snapshots.linaro.org migration to EC2

by Paul Sokolovsky

Hello, Testing of new EC2 instance to replace staging.snapshots.linaro.org is complete, here's publishing result: http://ec2-54-234-163-41.compute-1.amazonaws.com/android/~pfalcon/galaxynex… (Corresponds to https://android-build.linaro.org/builds/~pfalcon/galaxynexus-linaro/#build=…) Philip, can you please update staging.snapshots.linaro.org to point to the new host? staging.snapshots.linaro.org is internal testing host, so its migration probably doesn't affect anyone outside LAVA team, but next in queue is snapshots.linaro.org itself (where all Jenkins results go), so this is early notice of its upcoming migration too (no specific ETA, but optimistic plan is to do that this month). -- Best Regards, Paul 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

question about kernel source - 3.9.0-1-linaro-arndale #1ubuntu1~ci+130404024430 SMP PREEMPT

by Young, Chad

I tried using the method of find the kernel source suggested to me on a somewhat similar question. I want to do two things (1) find the source to "3.9.0-1-linaro-arndale #1ubuntu1~ci+130404024430 SMP PREEMPT" (2) figure out how to build the kernel so that is labeled "3.9.0-1-linaro-arndale #1ubuntu1~ci+130404024430 SMP PREEMPT" and not "3.x.x-x-generic" which is what it usually says when I compile a kernel source. Can someone point me in the direction of these answers? Thanks Chad
