A number of difficult problems this week, but some progress was made.

• Helped diagnosis of an audio codec driver problem with our the XO-1.75 kernel upgrade.
• Attempted diagnosis of a Fedora 17 ARM build problem with the llvm package, which was blocking a lot of things. We have a workaround now.
• Investigated the challenges around getting Flash and Java working on a GTK+-3 WebKit.
• Found a workaround to fix gcc crashyness on the XO-1.75, reported to Marvell.
• Diagnosed a WebKit crash on ARM, related to the javascript engine.

• Helped port OLPC’s runin tests to Fedora 17.
• Enabled olpc-update for the 12.1.0 builds.
• Finished off an old patch to reserve disk space for root on jffs2, which can help avoid a slowdown when the disk gets full.

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

• Automatic log truncation
• GNOME crash on bad system time
• Lack of SD card support
• XO-1 and XO-1.5 wireless after resume
• Correct handling of XO-1 PenTablet
• Slow loading of libertas firmware

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

• Implemented automatic partition/filesystem resize
• Some 12.1.0 odds-and-ends: XO-1.5 suspend/resume, initramfs bloat, GNOME font sizes, UBIFS boot problem, new boot animation, XO-1.75 key mapping

• Fixed some 12.1.0 odds-and-ends: disabling of tap-to-click, USB automounting, rebuilding library index, eth device naming, XO-1 partition mounting, Record photo capture, lack of wireless on XO-1.75, Frame key in Sugar.
• Diagnosed why OLPC trac was slow and made it faster.
• Clarified the process with Peter for contributions via updated Fedora packages for 12.1.0.
• Started working on automatic partition/filesystem resize.

• 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.
