Thumb-2 kernel on imx51/efikamx

by Dave Martin

Hi, Just tested the imx51 Thumb-2 kernel on efikamx here -- it boots fine, but we only went as far as the initramfs. Is anyone currently relying on CONFIG_LATENCYTOP? If so, we should investigate what the incompatibility is...

Remote Access to H/W

by Mounir Bsaibes

As one action from last kernel WG meeting, I have investigate the availability of boards Remote Access. Right now, we don't have anything setup for remote access. Either we have to have the boards in hand or we have to check the https://wiki.linaro.org/Internal/Hardware and see who has the needed board(s) and see whether we can run the tests on that board9s). The Validation's team is looking at supporting building and testing the landing team kernels, at that time we may have something we can work with. The kernel engineer will build and create the kernel image that needs to be tested, then he/she would run the setup that is availble to the Landing teams. (this is still work in progress, we don't know the exact details yet). On the long run, maybe we should open a Stakeholders Proposal to address Remote Access and make it easier to the engineers to reserve a board and use it for a short while. Regards, Mounir

.note.gnu.build-id section not really used in ARM kernel (and NOTES macro not present in linker cmd file)

by Frederic Turgis

Hi all, While testing systemtap v1.4, I encountered an issue in the tool that had been fixed in the past (and reintroduced recently). I have investigated with Redhat guys and here is what we have found: - root cause is that .note.gnu.build-id is mapped at address 0 in vmlinux (we did a readelf -S on vmlinux) - (.note.*) sections can be mapped at a specific location through NOTES macro defined in vmlinux.lds.h. vmlinux.lds.h mentions that minimal linker scripts has following content ... * _edata = .; * * EXCEPTION_TABLE(...) * NOTES - .note.gnu.build-id is mapped at address 0 because NOTES is not used in ARM linker cmd file. We are wondering if there is any specific reason with Redhat. Furthermore, .zImage.cmd contains "arm-linux-gnueabi-objcopy ... -R .note -R .note.gnu.build-id", where "-R" removes mentioned sections from the binary. We clearly don't want (.notes.*) sections, which could have appeared as /sys/kernel/notes Would there be an interest in mapping "notes" section in linker cmd file ? Regards Fred

Building the omap kernel for Thumb-2

by Dave Martin

Hi there, Talking with Loic just now, we thought it could be worth turning on Thumb-2 in the main omap kernel package after all, since we've at least seen it work on a few different boards now. It feels ready for wider testing. Is it possible for you to move to a newer snapshot of the 2.6.38 linaro tree, or will that be problematic at this stage? Since the imx51 kernel at least seems to build and boot in Thumb, it could be worth enabling a separate build in a PPA, but it's may not mature enough for everyone to use as the main kernel just yet. If you want to try this, you need CONFIG_ARM_UNWIND=y, CONFIG_LATENCYTOP=n and CONFIG_THUMB2_KERNEL=y Cheers ---Dave

Linaro 10.11 Igep v2 Wifi

by Encima

Hi All, Not sure if I have subscribed to the right list but I was wondering if anyone had some insight as to how to get the wifi working on the igep? I have downloaded the firmware, copied it to the lib/firmware. Can't see it anywhere though. ifconfig only shows eth0 and lo. Any help is appreciated and I apologise if this is the wrong list (or area completely!) Chris

The linaro-2.6.38 kernel is now open

by Nicolas Pitre

As the next Linaro release (11.05) will include the 2.6.38 kernel, it was decided that the linaro-2.6.38 branch would open early i.e. before the final 2.6.38 kernel is released. So there it is. All the extra patches that were available in linaro-2.6.37 should be included in linaro-2.6.38 at this point. Some notable exceptions at the moment are some Thumb2 support patches, and some ARMv6k compatibility patches. I expect to get a fresh set from Dave Martin soon for the former, and I'll eventually merge RMK's devel branch which would bring in the later. But as you should know already, the feature freeze is due this Thursday February 24th. So now is the time to consider the linaro-2.6.38 tree, put on top all the patches you want to see in the upcoming Linaro release, and ask me to merge them in. If you need some subsystem tree such as MMC to be included as well then now is the time to say so as well. Nicolas

IRC channel for today's Linaro kernel meetings

by Paul E. McKenney

Hello! Just a reminder, we are going to try to use IRC rather than phone for today's linaro-kernel meetings. Let's use #linaro-kernel on Freenode for today's linaro-kernel meetings. Thanx, Paul

[ACTIVITY] week 6 2011 (2011-02-07 - 2011-02-11)

by Dave Martin

== [ACTIVITY] [dave-martin-arm] Activity report for week 6 2011 (2011-02-07 - 2011-02-11) == === Activity === ==== hardware-n-kernel-standard-architecture ==== * Upstream link-time discard versus SMP_ON_UP problem still not fixed. More discussion with Russell: expect this to converge on some kind of solution within the next week or 2. In the meantime, I may suggest temporary merging of my workaround patch in linaro. * omap3/4 Thumb-2 compatiblity patches re-posted. Did some power management testing to exercise the code: power off suspend _may_ work on Beagle xM, but this board is hit by an erratum which makes it hard to test. Weirdly, this problem only strikes when the kernel is built in Thumb-2, but I can find no actual bug so far. Tony Lindgren has picked up my tree and my try to test this this. ==== performance-linaro-n-memory-footprint ==== * Methodology proposal now agreed with Steve Langasek, with a couple of minor modifications: https://wiki.linaro.org/Platform/DevPlatform/Specs/MemoryFootprintMethodolo… ==== miscellaneous ==== * Spent some time helping debug boot partition layout generated by linaro-media-create on OMAP. ==== Plans ==== * Tidy up the proposal for link-time section discard avoidance and report. * Discuss prioritisation for outstanding kernel tasks. * Write up the output from the Freescale i.MX BSP review discussion, and post for comment. ==== Absences ==== None planned.

February freeze and 11.05 Linaro kernel release

by Paul E. McKenney

Hello! The February 24th feature freeze is coming up very quickly. We therefore need any kernel patches that are to be included into the 11.05 Linaro kernel release to be submitted to linaro-dev (CCing nicolas.pitre(a)linaro.org) as well as upstream as soon as possible. Otherwise, we cannot guarantee that they will be included in the upcoming Linaro kernel release. Thanx, Paul

EDID

by Tom Gall

Kernel team, One of the outstanding bugs we have from Maverick is bug #660604, basically we have no EDID display support. The bug is currently marked low and I would like to suggest it should be raised in priority and best case added for the next release. The impact of this bug is for those that don't have LCDs which are able to display 1280x720 is basically an unusable graphical environment with any of our graphical seeds such as ALIP, netbook-efl. Now you might say, hey Tom, you can work around this, and sure one can if you want to go through the process to redo the kernel command line options which is a little less than optimal. I think if we're asking people to enter by hand display resolutions and refresh rates unlike other platforms such as intel then I think we've gone the wrong way. Regards, Tom

Availability of kernel .config, Module.symvers and vmlinux in a package ?

by Frederic Turgis

Mail was sent to linaro-dev, I am also forwarding it to linaro-kernel as it may get more attention. Do not care about the "kernel recompilation" part, someone indicated me the right wiki. Hi, I have the task to check systemtap behaviour. It requires .config (found in /boot so OK), Module.symvers and vmlinux. Well, I could recompile the kernel but I have been used getting these packaged by our integration team at Texas Instruments ;-) I am wondering if these shall not be provided to end users and how they could be provided. From various reading, I have the impression I would need a linux-image-debug-xxx package: * is there some for various hwpacks (especially panda in my case) ? * is it sufficient ? vmlinux was not packaged as such by our integration team so I have doubts about it In any case, I am anticipating kernel recompilation. Is there any Linaro deviation from Ubuntu method ? thanks for your help Regards Fred
