OLPC weekly update 20/04

This week I’ve been working on some assorted bugs affecting OLPC’s upcoming 12.1.0 software release:

This week, and during the easter week, I’ve been working on OLPC’s 12.1.0 software release.

Finished implementing an initial plymouth-based OLPC boot animation. With systemd, bootup is so fast that (after first boot) we barely have time to do any animating on screen.
Overcame the last few obstacles for an ARM build of 12.1.0; this will be released tomorrow.
Implemented the new build filename scheme for 12.1.0 and onwards.
Fixed a handful of small issues in the 12.1.0 builds.

Fixed some more Fedora 17 ARM package build issues, inching closer to a F17 XO-1.75 image for testing.
Updated olpc-dm for systemd, solving various problems including a lack of networking in the latest 12.1.0 development build.
Solved XO-1 boot problem in latest development build.
Started development of an OLPC boot animation theme for plymouth, so that we can drop our custom animation software.
Formalised OLPC OS 12.1.0 release plan and schedule.

A summary of my work over the last week:

Fixed and built various Fedora 17 packages for ARM, working towards a OLPC XO-1.75 build. 5 problematic packages remain.
Fixed a hippocanvas-related crash causing Sugar to segfault on start on Fedora 17.
Progressed on getting a couple of kernel patches upstream.
Worked on getting a new XO-1/XO-1.5 Fedora 17 image built from OLPC infrastructure. Nearly there.

My recent OLPC work from the last 2 weeks includes:

Helped fix an XO-1 Record activity crash with new orc
Helped fix Scratch’s difficulty finding libv4l2.
Fixed a via-camera kernel issue producing bad colours for scaled images
OLPC OS 11.3.0 release
Documented the current state of the Linux 3.1 kernel for OLPC XO-1/XO-1.5 and pushed forward with some pending upstream patches
Attended the OLPC SF summit where I presented about some current/upcoming developments from OLPC and helped solve some small deployment technical issues presented by other attendees.
Attended the Sugar GTK3 hackfest and helped get an initial sugar-toolkit and sugar-artwork port running to the point where we can have mostly functional GTK3 activities running.
Added rsvg gobject-introspection support.

Two 11.3.0 release candidates: build and testing.
More progress around XO-1.5 input issues with synaptics driver and suspend/resume behaviour.
Fixed mmap access to the XO-1.75 audio device, solving a handful of user-visible audio problems, and continued looking at problems in this area.
Diagnosed a XO-1 audio regression for secured laptops.
Coordinated the solution for the loss of serial console kernel messages in secure mode on XO-1.75.
A couple of small fixes to the forward-looking Fedora 16+ platform for XO
Continued assistance with the Fedora 15 ARM efforts, which has now kicked off the next stage of the mass rebuild efforts.

Investigated why keyboard autorepeat has enabled itself in recent software builds.
Revived OLPC’s Browse PDF plugin for 11.3.0
Completed the switch to the sentelic driver for our AVC touchpads, to disable tap-to-click on a greater set of XO laptop hardware configurations.
Continued investigating the possibility of using the synaptics driver for our hardware configurations with synaptics hardware.
Fixed XO-1.75 activation problems with media mounting and GUI display.
Progress on Fedora 15 ARM porting, and Sugar hippocanvas removal
11.3.0 build 8 release and testing, and preparation for a release candidate build

Fixed a network configuration problem on OLPC’s ARM build systems which was causing some headaches
Solved an issue on our XO-1.75 software build system that was causing filesystem corruption
Helped Fedora with F15 ARM building efforts
Continued work on bringing Fedora 16+ to the XO platform
11.3.0 build 7 release and testing
