Overo stability problem/Overo hwpack support

by Sudhangathan B S

To argue, I'm with Steffen Hemer, I'm working for a practical project, I'm trying to include MADC module and trying to compile a kernel for lot while now, without success, to be more serious, my boss is counting on me. Is it worthwhile trying this at all...? Every time i follow instructions at https://wiki.linaro.org/Resources/HowTo/KernelDeploy , I end up with a non-working image, or kernel that panics, doesn't boot finally. I have all the problems that Stefen Hemer says, though haven't tried 12.06. I have only tried upto 12.03 since 11.07 and also an old and stable 11.05 Ubuntu Desktop, which I downloaded long back. 11.05 is an image that i'm using since long for all activities now. I was pretty impressed with it, inspite of it being a little slow. Please advice which version should I use with LinaroMediaCreate and which version of kernel should I compile. I need these features: Stable Bluetooth, Wi-Fi with fully working Ad-Hoc mode, MADC, GPIO controls (which I never had problems), And also later dreaming to include advanced power management features and XIP kernel. I can share more detailed info if anybody out there says it's solvable.. Counting.... --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 ---------------------------------

Overo stability problem/Overo hwpack support

by Steffen Hemer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I'm trying to get a stable version of Linaro on my Gumstix Overo board for quite a while now but without success. I started with the recommended version 12.03 alip-image (as there is an "official" hardware pack linked on the website), but it crashes regularly on shutdown, the c/c++ compiler also hangs undeterministically and the Xserver crashes too (ok I could live without this) . The problems on shutdown and the hardresets seem to make the system more and more unstable. With the latest hardware packs and Linaro 12.06 it doesn't even boot because of the following error: [ 5.774139] omapfb omapfb: no driver for display: dvi [ 5.780059] omapfb omapfb: cannot parse default modes [ 5.787200] Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP THUMB2 Why isn't there an "official" hardware pack for the Overo since last three releases? Does anyone have a solution for this? Anyone using a linaro image on overo which is stable? Which versions do you recommend?

[PATCH v3 0/5] ARM: topology: set the capacity of each cores for big.LITTLE

by Vincent Guittot

This patchset creates an arch_scale_freq_power function for ARM, which is used to set the relative capacity of each core of a big.LITTLE system. It also removes the broken power estimation of x86. Modification since v2: - set_power_scale function becomes static - Rework loop in update_siblings_masks - Remove useless code in parse_dt_topology Modification since v1: - Add and update explanation about the use of the table and the range of the value - Remove the use of NR_CPUS and use nr_cpu_ids instead - Remove broken power estimation of x86 Peter Zijlstra (1): sched, x86: Remove broken power estimation Vincent Guittot (4): ARM: topology: Add arch_scale_freq_power function ARM: topology: factorize the update of sibling masks ARM: topology: Update cpu_power according to DT information sched: cpu_power: enable ARCH_POWER arch/arm/kernel/topology.c | 209 +++++++++++++++++++++++++++++++++++++----- arch/x86/kernel/cpu/Makefile | 2 +- arch/x86/kernel/cpu/sched.c | 55 ----------- kernel/sched/features.h | 2 +- 4 files changed, 189 insertions(+), 79 deletions(-) delete mode 100644 arch/x86/kernel/cpu/sched.c -- 1.7.9.5
