The need for more verbose work item updates

by Alexandros Frantzis

Hi all, in some of the blueprints I am following, I have noticed that many work items updates (e.g. to DONE/POSTPONED/BLOCKED) are not accompanied by any additional information. Of course, not all work items need more information, but some are meaningless to an external viewer without it. This is a general observation across Linaro and I am as guilty as any. As an example, consider the following (semi-fictional) work item updates: + Add Qt tracing support for pixmaps: POSTPONED + Create a bazaar branch for libX: DONE + Select and port an application to GLES2: DONE + Test that the application functions correctly on ARM: BLOCKED These updates raise many questions: * Why was Qt tracing for pixmaps postponed? * What is the exact location of the published branch? * Which application was selected for porting? * Where can I find the ported code for the application? * Why is the application test blocked? Such information is usually placed at the top of the whiteboard, like this (at least this is how I am doing it): [alf May 8]: Postponed work on Qt pixmap tracing because it turned out we can trace Qt/Webkit without it, so it is not considered critical anymore. [alf May 10]: Uploaded branch to lp:libX [alf May 10]: Selected application Y for porting to GLES2 [alf May 12]: Finished porting Y to GLES2 and uploaded it to http://git.linaro.org/... [alf May 13]: Blocked on testing the ported application Y because of an issue (LP: #666666) with the 3D drivers for chipset Z. In conclusion, I would like to encourage more verbosity in our updates, so that others can easily follow and appreciate all the great work that we are doing. Thanks, Alexandros

OMAP3 IGEPv2: kworker/0:0:1030 blocked on latest snapshots

by Christian Robottom Reis

Hi there, I'm playing around with the latest snapshots on my IGEPv2 and I'm seeing a recurring message posted to the console while using it: [ 1561.340942] INFO: task kworker/0:0:1030 blocked for more than 120 seconds.

I haven't been able to notice anything negative in my use of the system (downloading and installing packages, editing files, running cpuburn and stress).

[PATCH v4 0/2] SMDKV310 Board Support

by Chander Kashyap

Hi, This patchset adds support for a new board SMDKV310, based on S5PV310 SOC. This SOC is very similar to S5PC210 SOC, hence we are re-using this SOC code. Specific changes in PATCH v3 are mentioned in specific patch files.

Do we need prebuilt images of all types?

by Guilherme Salgado

Hi, During LDS we agreed to provide prebuilt Linaro images at our milestones[1], for users who can't/won't run linaro-media-create. One thing we forgot to discuss, though, is if it's worth doing so for all image types or just for the LEB(s). Our downloads page (http://www.linaro.org/downloads/) has 4 different image types, but the email for weekly testing, for example, lists only UbuntuDesktop as official and the others as community images. More importantly, though, I'm not sure the people who just want to try Linaro quickly will be interested in anything other than UbuntuDesktop at this point, so we might as well avoid the extra work to provide images that are unlikely to be of any use. Can anybody think of other reasons why we should provide images of all types?
