[RFC][PATCH 1/9] ARM: OMAP3: cpuidle - remove rx51 cpuidle parameters table

by Daniel Lezcano

As suggested, this table is an optimized version for rx51 and we remove it in order to consolidate the cpuidle code between omap3 and omap4, we remove this specific data definition which is used to override the default omap3 latencies but at the cost of extra code and complexity. In order to not lose the values which probably took time to be measured, the table is converted into a comment with an array description.

suspend function has been merged into pm-qa

by Hongbo Zhang

Hi all, The suspend test[1] had been integrated into pm-qa. Fetch the source: git clone git://git.linaro.org/tools/pm-qa.git Usage of suspend test: make -C suspend check NOTE: Tests suspend_03 and suspend 04 only make sense on Ubuntu laptop, they are currently disabled for LEBs. If you want to test them on laptop, switch on the macros inside each script manually please. Total solution for LEBs will come soon, any problem please feel free to let me know, thanks.

Still plenty of things to fix, and not long till release-time. Friday is the day to come fix some ARM bugs. You know you want to. You have a choice between the usual FTBFS issues listed here: http://people.linaro.org/~rsalveti/arm-porting-queue/arm-porting-queue-repo… and multiarch cross-dependency/cross-building issues summarised here: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/MultiarchCrossBui… with logfiles here http://people.linaro.org/~wookey/buildd/precise/sbuild-ma/status.html There is a pile of stuff, much of which is _really easy_. This page tells you all you need to know for filing simple multiarch metadata bugreports: http://wiki.debian.org/Multiarch/CrossDependencies Please come along to #linaro @ freenode and get stuck in with a few bugs.

[RFC][PATCH 0/7] OMAP4 cpuidle cleanup

This patchset is a proposition to improve a bit the code. The changes are code cleanup and does not change the behavior of the driver itself. A couple a things call my intention.

Gmail corrupting spaces in plain-text mail?

by Dave Martin

Hi all, Does anybody know how to stop the Gmail webmail frontend from corrupting sequences of space characters in preformatted text? When replying to a plaintext mail, Gmail seems to turn every second space into an ISO8859-1/Unicode non-breaking space character (U00A0). This seems to be a workaround for broken mail readers which would incorrectly collapse spaces in implicitly fixed-format text in received messages. Unfortunately, it's also an effective workaround for correct behaviour by properly-implemented mail clients. Direct replies via SMTP to smtp.googlemail.com don't get destroyed in this way, unless a broken client is used is used to generate the reply. This seems to be the cause behind patch discussion threads turning, sooner or later, into a mass of ? characters (this is what some agents like Mutt squash non-ascii characters to when quoting the original message in ascii plaintext replies -- this compounds the problem but is not the root cause -- the text is already badly damaged by this stage). See: * http://www.ieft.org/rfc/rfc2646.txt * http://lists.luv.asn.au/pipermail/luv-main/2011-November/000580.html Apart from "never reply to patches via webmail", does anyone know a workaround?

Graphics working group components for 2012.03 (cont.)

by Jesse Barker

Hi all, Somehow, I completely forgot about the release for the unity-gles project. All OpenGL|ES enablement for the Ubuntu Unity plugin (the Unity3D "shell") and the nux library has been merged into the respective trunks on launchpad for those projects (lp:unity, lp:nux), so Linaro will not be releasing those. There are 2012.03 release tarballs for compiz itself (both compiz-core and compiz-plugins-main) at https://launchpad.net/unity-gles. These will support Precise only, due to external library dependencies. cheers, Jesse

Graphics working group components for 2012.03

by Jesse Barker

Hi all, The graphics working group is pleased to announce the 2012.03 release for the following components: - glmark2 * Offscreen rendering support using framebuffer objects. * New command line switch to allow selection of end-of-frame method, - glcompbench * New 'blur' test. * Updated glproxy support. - glproxy * Enhanced selection of EGL vs. GLX based upon new detection API. These are all available for download from their respective project pages, conveniently linked from the project group page at: https://launchpad.net/linaro-graphics-wg The release for the linaro-mm-sig project is being rolled up into the linux-linaro kernel tree (linux-linaro branch of git://git.linaro.org/kernel/linux-linaro-tracking.git) for this cycle, and should see updates between cycles, as well moving forward. Enjoy! cheers, Jesse

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.
