ANN: git.linaro.org going down for up to 1h

by Danilo Šegan

Hi all, We've experienced slowness with git.linaro.org yesterday that is harming our release process. Since we've already had new machine for hosting git.linaro.org being set up (in the final stages of it), we're about to switch the machines around. We've spent the morning testing the new machine and it seems ready to go. This means that we'll be shutting off any git access to git.linaro.org shortly (at 12:30 UTC), and we expect a downtime of 30 minutes to get new machine up (but let's keep the window of 1h just in case). If you have any urgent issues, please shout before we go for the downtime. Sorry for such a short notice! Cheers, Danilo

Powering up snowball over USB

by Dave Pigott

Hi all, Sorry for the wide distribution, but I've got a rather curious problem. I'm trying to get a Snowball V11 PDK working in the validation lab, and the only way to get it to boot on power-on is to power it over USB and control the power through a USB power adaptor. While this works admirably, the problem is that when I try to soft-reboot I get the usual: Broadcast message from root@master (/dev/ttyAMA2) at 15:48 ... The system is going down for reboot NOW! * Asking all remaining processes to terminate... [ OK ] * All processes ended within 1 seconds.... [ OK ] * Deconfiguring network interfaces... [ OK ] * Deactivating swap... [ OK ] umount: /run/lock: not mounted * Will now restart [ 1279.346801] Restarting system. and then nothing. It just hangs and never comes back until I power cycle it. BTW: Sometimes I get the whole of the "Restarting system" message, sometimes just half of it. Has anybody any idea why this might be the case and, if so, what I can do about it?

[PATCH 0/6] HACK: OMAP: testing common clk features

by Mike Turquette

This series is just informational and illustrates how to use some of the common struct clk features. I wrote this code when testing the common struct patches. These are hacks and put some of code to use practically. Firstly this series models the clocks between the MPU PLL and the ARM IP a bit more closely. Then CPUfreq is changed to use this new mpu_clk, which passes the rate change up to the PLL. Another new clk, mpu_periphclk, is introduced which divides mpu_clk by 2. The recent smp_twd code from Linus W. is modified to use clk rate change notifiers for mpu_periphclk instead of CPUfreq notifiers. Finally this series introduces a new OPP for the MPU on OMAP4 which bypasses the MPU DPLL and exercies some of the clk frameworks parent switching code. Using this OPP is probably unsafe and will permanently ruin your board, your desk and your home. You can find the common struct clk patches at, https://lkml.org/lkml/2011/12/13/451 OMAP support for the common struct clk is needed for this series and can be found at, http://article.gmane.org/gmane.linux.ports.arm.omap/68217 These patches can be found at, http://git.linaro.org/gitweb?p=people/mturquette/linux.git;a=shortlog;h=ref… git://git.linaro.org/people/mturquette/linux.git v3.2-rc5-clkv4-omap-pm-testing Linus Walleij (1): smp_twd: Reconfigure clockevents after cpufreq change Mike Turquette (5): HACK: omap: opp: add fake 400MHz OPP to bypass MPU omap: clk: .round_rate for propagating to parents HACK: omap: clk: add mpu_periphclk clk node HACK: cpufreq: omap: change mpu_clk's rate HACK: arm: reprogram twd based on clk notifier arch/arm/kernel/smp_twd.c | 89 +++++++++++++++++++++++++++++++-- arch/arm/mach-omap2/clkt_clksel.c | 8 +++ arch/arm/mach-omap2/clock.h | 2 + arch/arm/mach-omap2/clock44xx_data.c | 37 ++++++++++++++- arch/arm/mach-omap2/opp4xxx_data.c | 9 ++++ drivers/cpufreq/omap-cpufreq.c | 2 +- 6 files changed, 139 insertions(+), 8 deletions(-) -- 1.7.5.4

linux-next not booting on snowball

by Daniel Lezcano

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I am using the linux-next head git tree on a snowball V5. The kernel hangs at "Uncompressing kernel... done". After bisecting, the patch where the kernel does no longer boot is: commit 549158d2ab01e8370d2773044fe09738a26f7086 Author: Nicolas Pitre <nicolas.pitre(a)linaro.org> Date: Thu Aug 25 00:35:59 2011 -0400 ARM: move iotable mappings within the vmalloc region In order to remove the build time variation between different SOCs with regards to VMALLOC_END, the iotable mappings are now allocated inside the vmalloc region. This allows for VMALLOC_END to be identical across all machines. The value for VMALLOC_END is now set to 0xff000000 which is right where the consistent DMA area starts. To accommodate all static mappings on machines with possible highmem usage, the default vmalloc area size is changed to 240 MB so that VMALLOC_START is no higher than 0xf0000000 by default.

[PATCH 0/7] RFC: convert OMAP to common struct clk

by Mike Turquette

This patch series is an RFC for converting OMAP to the common struct clk. These patches are based on v4 of the common struct clk series: https://lkml.org/lkml/2011/12/13/451 OMAP's old struct clk has been renamed to struct clk_hw_omap, but left essentially the same. This series only targets OMAP4 and was only tested on a 4430 Panda. The next step is to figure out: * what are the various clk types we want to support in separate structures * where does the "clk driver" code live (still in mach-omap2?) * kill off plat-omap/clock.* completely? I vote yes. These patches can also be found at, http://git.linaro.org/gitweb?p=people/mturquette/linux.git;a=shortlog;h=ref… The same series merged with Kevin's PM branch (to get CPUfreq working) can be found at, http://git.linaro.org/gitweb?p=people/mturquette/linux.git;a=shortlog;h=ref… This series will be followed up shortly with another set of patches for "testing" the clk rate change notifiers, parent propagation of rate changes and debugfs re-parenting.
