v.l.o

by Dave Pigott

Hi all, I got some bad news last night. Our ISP told me there would be a delay in getting our service up and running in the new offices. I spoke to them this morning and they're telling me that it will *probably* be Wednesday before we get connectivity, but we will know more on Monday. As a consequence I am putting v.l.o back online and delaying the move. My intention is to take it offline again on Thursday of next week and move on Friday. Obviously this plan may be fluid based on the news we get on Monday. I will obviously keep you all posted. Many apologies for the delay and thanks for your patience, Dave Dave Pigott Validation Engineer T: +44 1223 45 00 24 | M +44 7940 45 93 44 Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog

[PATCH v13] Regulator: Add Anatop regulator driver

by Ying-Chun Liu (PaulLiu)

From: "Ying-Chun Liu (PaulLiu)" <paul.liu(a)linaro.org> Anatop is an integrated regulator inside i.MX6 SoC. There are 3 digital regulators which controls PU, CORE (ARM), and SOC. And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB). This patch adds the Anatop regulator driver.

ci.linaro.org is back and (hopefully) stable.

by James Tunnicliffe

Hi, The migration of ci.linaro.org to new hardware is complete. We hope that this will result in a more stable and responsive system. We have had a few builds run successfully so everything seems to be fine, but we will be keeping an eye on it. Please let the infrastructure team know of any problems that you see with the new set up and we will make sure they are fixed ASAP. Thanks, -- James Tunnicliffe

[PATCH v8 0/8] Consolidate cpuidle functionality

by Robert Lee

This patch series moves various functionality duplicated in platform cpuidle drivers to the core cpuidle driver. Also, the platform irq disabling was removed as it appears that all calls into cpuidle_call_idle will have already called local_irq_disable(). These changes have been pulled into linux-next. Len, Andrew, can a request be made for Linus to pull these changes?

ci.linaro.org planned downtime.

by James Tunnicliffe

Hi, It is my intention to take ci.linaro.org offline for about 15 minutes at 13:45 UTC (http://www.worldtimeserver.com/current_time_in_UTC.aspx) so we can duplicate the server and start moving it to a larger EC2 instance. Users will know that ci.linaro.org has been running very slowly for a while and we hope that this move will make it usable while we continue to debug the performance problems that we are seeing. If the downtime will cause you significant problems, please get in touch and we will arrange a better time. Thanks, -- James Tunnicliffe

I seem to recall a small amount of agro getting the kernel config right, but u-boot was always able to recognise the device. I suggest that you find (borrow) another SATA device to test with. Good luck! I was able to borrow another SATA drive and that works, thank heaven. I thought I was going crazy for a while -- don't ask how many times I re-compiled the kernel. I did trace the problems I having to the ahci code in the kernel not properly handling an ahci CONINIT event generated by my WD5000BEVT drive. Seems this drive has extra SATA features implemented so that it can be used in hot-plug arrays and these features aren't recognized by the kernel driver so it just seems to shut down the drive and ignore it. The other SATA drive that I do have working with the kernel doesn't implement the extra features so the kernel is happy. Presumably these problems were fixed in later kernels and the patches didn't make it into Freescales 2.6.35.3 branch. On the other hand, the kernel might be fine and the firmware in the drive isn't conforming to the ahci specs, but I think that wold cause problems with the drive on other systems. I'm going to keep looking into this as I do want to get my 500GB SATA drive working with the iMX53 Quick Start. Mike

LAVA Downtime Planned

by Paul Larson

This is just an early notification that the Linaro validation farm will be physically moving to a new site next week. Unfortunately, the network cables won't stretch that far, so it will mean some downtime. :) Here's the tentative plan: Wednesday, March 21st - the rack with the toolchain server will be shut down, crated and sent off Thursday, March 22nd - pretty much everything else will go offline (main LAVA server, development boards) Friday, March 23rd - physical move will happen, and if all goes well (what could possibly go wrong?!) the main site and as many of the boards as possible will go back online in their new home Saturday, March 24th to Sunday, March 25th - finish configuring and bringing up cloud services, toolchain server, etc. There's another bit of good news here, that the lab will be getting a much needed upgrade in the internet connection. A partial (but significant one) at first, and a bigger one in about a month or so with redundant connections. Bear in mind that this is just the tentative plan, Dave or I will send out a reminder and update as the date gets closer, or if something changes. Thanks, Paul Larson
