The toolchain isn't built with -mcallee-super-interworking enabled. Could we get that turned on?

[PATCH] UBUNTU - ARM: adding i2c eeprom driver to read EDID

by Mathieu Poirier

All, This patch creates an entry in /sys that allows user space utilities such as 'decode-edid' and 'parse-edid' to read the monitor's EDID information. Please consider adding to your tree. Processor: Omap3 Platform: beagleboard Cx Mathieu. >From 7d0d86809864cb852988a296b12dff6436c45480 Mon Sep 17 00:00:00 2001 From: Mathieu J.

PM support for OMAP

by Ameya Palande

Hi, AFAIU pm branch on linux-omap tree contains required patches, but they are not yet ready for inclusion in upstream kernel. How is linaro planning to provide pm support for TI omap[34] chips? Cheers, Ameya.

Eclipse Day 2010

by Loïc Minier

Hey Slides from Eclipse Day 2010 were just published at: http://wiki.eclipse.org/Eclipse_Day_At_Googleplex_2010#Presentation_Slides I think we're lacking in developers tools ATM, and found some presentations interesting, the two I read in full were: Eclipse Linux Tools Project - Andrew Overholt (Red Hat) which I recommend and: Android Tools for Eclipse - Xavier Ducrohet (Google) which I don't recommend. Cheers -- Loïc Minier

Restricting architectures

by Michael Hope

Hi there. We've been having a discussion in the Toolchain WG regarding Thumb-1 improvements. I want to decline doing them as I've assumed that Linaro is focused on the Cortex-A series, but I can't find that written down anywhere. May I limit the Toolchain WG to currently or nearly shipping Cortex-A implementations? This means: * Cortex-A profile only * ARMv7 only * ARM and Thumb-2 instruction sets * With or without NEON * With either VFPv3 D16 or D32 * With or without SMP We will try to do no harm to other architectures or earlier ARM versions. The Thumb-2 routines may be applicable to the Cortex-M and Cortex-R series but we will not optimise for them. I'd like Linaro to state this explicitly in the next round. https://wiki.linaro.org/Linaro1011/TechnicalRequirements defines a 'Standard ARMv7 Configuration' but there's no higher level statement justifying it, no statement restricting us to it, and it includes ARM, Thumb-2, and Thumb-1. -- Michael

Profiling fixes for -stable

by Will Deacon

Hi Nicolas, If you're still accepting fixes for the 2.6.35 stable Linaro Kernel then I have some small profiling updates for you: The following changes since commit 9fe6206f400646a2322096b56c59891d530e8d51: Linus Torvalds (1): Linux 2.6.35 are available in the git repository at: git://repo.or.cz/linux-2.6/linux-wd.git for-linaro-stable Will Deacon (4): oprofile: don't call arch exit code from init code on failure ARM: oprofile: fix and simplify init/exit functions ARM: perf: reword comments relating to perf_event_do_pending ARM: perf: fix event validation arch/arm/include/asm/perf_event.h | 2 +- arch/arm/kernel/perf_event.c | 12 ++++---- arch/arm/oprofile/common.c | 47 +++++++++++++++++++----------------- drivers/oprofile/oprof.c | 11 +------- 4 files changed, 34 insertions(+), 38 deletions(-) Nothing groundbreaking, but worth having nonetheless. These guys are also sitting in my for-linaro branch but I'm hoping they'll be in 2.6.36 anyway. Cheers, Will

per flavour linux-linaro source packages

by John Rigby

Tim, Building the three flavours of the linux-linaro kernel package currently takes over eleven hours. To improve that situation in the long term there are ideas about cross compiling in the build farm but that is still in the future. In the short term we would like to have multiple source packages. I have a script (attached) that tweaks the tree per flavour and runs debuild -S to produce one source package per flavour. I can include the script under debian/linaro/scripts for producing per platform sources or as an alternative I can have per flavour branches of the linux-linaro tree, probably produced by a similar script, that you could pull from and do the normal source generation per branch. Which of these do you prefer or do you have a third better idea? Thanks for your input. John

imx51 and CONFIG_NEON

by John Rigby

Amit, Bryan: Do you know what the correct setting for CONFIG_NEON is for MX51? In a discussion on IRC there was mention that there is a patch that makes it safe to turn on. Do you know if that patch has made it upstream? Thanks, John
