Mobile UXes - From the DebConf11 BoF to the stars
Hi all, This is the sumary of the discussion held at DebConf11 during the Mobile UXes BoF, on 2011-07-29, at 18h00 in the meeting room. (= tl;dr version =) (Search for Proposal down this mail.) (Please answer to debian-de...@lists.debian.org only. ) The point of this mail is to inform people and communities of the content of those discussions and propose a sort-of plan of action. Note that nothing has been clearly decided there but the discussion was really nice and promising so I sort-of hope the consensus acknowledged upon there can be reflected online. = Outline = 0 - Commented overview of the various available stacks 1 - Proposal for future actions and meet-together = 0 - Commented overview of the various available stacks = The initial idea to frame the discussion was to share experiences and opinions about known free software mobile stacks: are they packaged in Debian? What has been the experience so far? If not, why not? The main reference to build up this list has been http://wiki.debian.org/Smartphone, which is still a good reference! Now to the list. == Android == The Canonical effort [0] to port an Android execution environment is currently reported as a dead-end. The most free-software-friendly efforts reported are IcedRobot [1] and Replicant [2]. They don't seem ready enough for inclusion in Debian though but we should keep an eye on them. [0] https://wiki.ubuntu.com/Specs/AndroidExecutionEnvironment [1] http://icedrobot.org [2] http://replicant.us/ == MeeGo == Back when the MeeGo project was launched, some hoped it could be Debian-based. Some persons from the Debian community tried to make that a reality back then but didn't succeed. Then the pkg-meego team [3] was formed to get software produced by the MeeGo project in Debian. This effort has faced a tough reality with regards to project management, interfaces stability, FHS respect, trademark policies, etc; and as a result it is currently stalled. Nowadays, various software pieces produced by or within the MeeGo project are probably interesting to get in Debian: - Maliit [4] it is the input methods solution used in MeeGo (in particular it's the project behind the Harmattan virtual keyboard / input method; also used for the N900/N950 Community Edition) - the Tablet User Experience [5] released by Intel earlier this year. - Handheld UX in the MeeGo CE form [6] As a side-note; the software released with the Nokia N9 (of which the swipe user interface [7] is not known to be available as free software) is available as a downloadable qemu image [8]. MeeGo CE [9] is a community effort both to make free MeeGo releases for a few smartphones, and to make MeeGo as a project more transparent by being an example of a contributing vendor. Since the project aims for a product level quality in the UIs, the packages they've put on top of MeeGo Core and integrate back to the Core are interesting for Debian as well. Timo Jyrinki wrote a very interesting blogpost on this topic [10]. [3] http://pkg-meego.alioth.debian.org/ [4] http://maliit.org [5] https://meego.com/downloads/releases/1.2/meego-tablet-developer-preview [6] https://build.pub.meego.com/project/packages?project=Project%3ADE%3ATrunk [7] http://www.developer.nokia.com/swipe/ux/ [8] http://harmattan-dev.nokia.com/ [9] http://wiki.meego.com/N900 [10] http://losca.blogspot.com/2011/08/meego-ce-and-freesmartphoneorg.html == Maemo == Maemo [11] is the Debian derivative that powers the Nokia N900 that was one branches of the MeeGo merge. Nowadays, both Maemo 6 and Harmattan (software basis of the Nokia N9) are reported to be dead-ends. A Debian team [12] was formed to work on the inclusion of the Maemo software back in Debian, but it decided earlier this year that Maemo is a dead end and removed Maemo related software from Debian [13]. It could still make sense to package some of the Maemo GTK themes to make running unmodified GTK applications easier on mobile devices. Openmoko also produced some. [11] http://maemo.org [12] http://wiki.debian.org/pkg-maemo [13] http://article.gmane.org/gmane.linux.debian.alioth.maemo.maint/1013 == GNOME Mobile Embedded Initiative == The GNOME Mobile Embedded Initiative was announced in 2007 for developing and promoting the use of the GNOME platform in mobile devices. It is not packaged in Debian (although the GNOME team might be able to give more insightful information) and doesn't seem to have a home on the Internet. It is part of the Hackable1 distribution (see below). == KDE Plasma Active == From their website: KDE Plasma Active [14] aims at creating a cross-device user experience for emerging devices such as tablet computers, media centers, smartphones, and more. It is currently not packaged in Debian, but some members of the pkg-qt-kde team could certainly be interested [15]. [14]

Hi Ben, ael, I am reading this on my phone and will not be able to look into this properly (ie access a computer) before next week. In the mean time: strace logs would be very useful. And maybe the problen has to do with the new driver doing real handshaking while the old one effectively ignored hs signals iirc.

Bug#640964: linux-image-3.1.0-rc4-486: BUG() triggered on XO-1 hardware

Package: linux-image-3.1.0-rc4-486
Version: 3.1.0~rc4-1~experimental.1
Severity: normal
During boot on an OLPC XO-1, I encounter the following problem. I
believe it's the statement BUG_ON(a-cpuid = NCAPINTS*32), though I'm
not staring at an exact copy of linux-2.6 source.
[...]
Agreed.
Variable a is in the EBX register, value 0xc143c668. Looking at a dump
of this kernel image, the __alt_instructions array starts with:
c143c638 7e51bcff 1c05 1a000503 7d51bcff ~Q..}Q..
c143c648 1305 1a000503 6653bcff 0a05 fS..
c143c658 19000503 ce55bcff .U..
c143c668 9a000200 cf55bcff f104 e4000303 .U..
...
Converting back to C structures:
/* instr_offset, repl_offset, cpuid, instrlen, replacementlen */
{ 0xffbc517e, 0x051c, 0x001a, 0x05, 0x03 },
{ 0xffbc517d, 0x0513, 0x001a, 0x05, 0x03 },
{ 0xffbc5366, 0x050a, 0x0019, 0x05, 0x03 },
{ 0x, 0xffbc55ce, 0x, 0x00, 0x00 },
{ 0x0002009a, 0xffbc55cf, 0x04f1, 0x00, 0x00 },
...
Oops, we have 4 bytes of zeroes between what should be elements 2 and 3.
That results in __alt_instructions[4].cpuid == 0x04f1 which trips the
BUG check. This is nothing OLPC-specific; it's going to happen on any
machine trying to boot this image.
So the question is, where does that padding come from?
Ben.

I say we take off; nuke the site from orbit. It's the only way to be sure.

Bug#640966:
Updating that I managed to flop around like a noob and still install the linux-image-3.0.0.1-686-pae package to upgrade my kernel and it seems to have fixed the problem. I don't know how to troubleshoot the original problem, but if you need me to run any other diagnostics, I can still boot into the old kernel.
