Daniel Drake — Fri, 11 May 2012 12:37:40 +0000

12.1.0 moved into bugfixes-only mode, and Sugar activities have been frozen.
Fixed some 12.1.0 odds-and-ends: RPM on XO-1, unclean rootfs handling on shutdown, re-enabled XO-1.75 serial console, got a couple of wakeup event tracking patches upstream.

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.

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.
