expand fs issue(?)
Installed 21009o2.zd in 2 XO-1.75 and on the one the fs failed to expand. fdisk shows that the card is indeed 4GB and OFW warns in red writing that the image is smaller than the device. Anything I should be looking for specifically before I retry or after, if this repeats? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Capture the kernel dmesg output after boot. Daniel added some additional debugging lines to the resize logic, and these, if my memory serves me, go into the kernel message log.

I'll do that now so that it will be included in the next one. At that point we'll need dmesg output, but it will have to be from first boot.

Status of audio on 3.3 kernel for ARM
Hi, I spent most of Friday and another 4 hours on Saturday working on the arm-3.3 audio issue. The problem is that only silence is produced. From what I can see the core of the problem is that the DAPM (dynamic audio power management) code is passed a representation of the widgets (amps, muxes, mixers) inside the audio codec. Then, when playing a sound, it has to find a route from the input (DAC, in the case of playback) to output (e.g. speakers), and then power up all the components on that route. When playing sound normally, it appears not to find a meaningful route and leaves all of the widgets powered down. This can be seen with cat /sys/devices/platform/soc-audio/*5631/dapm_widget (and you can compare to 3.0 where various things do get powered up during playback). If you make some tweaks to the mixer controls (even ones that should have no net effect) you can sometimes poke DAPM into looking for a route again and finding one and powering up the right components, e.g. http://mailman.alsa-project.org/pipermail/alsa-devel/2012-May/051686.htm To solve this, I first tried to understand and debug the DAPM logic. This is tedious and time consuming, with so many widgets and routes in our codec driver there is a lot of recursion and after a few hours I still couldn't make any sense of it. I then tried to simplify our driver, removing practically all routes and widgets at the DAPM level and just pre-configuring registers to have the right components for audio playback through the speakers working. No luck there either - couldn't get any audible output. I think this is the right approach though - first remove all the dynamic stuff just to have playback working, then re-add the widgets and routes one-by-one (based on the codec datasheet which has a nice logic diagram) with repeated testing to make sure nothing gets broken. This seems like a hard issue. Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

As far as I know, we have not yet found a case of corruption which can be meaningfully fixed by fsck. We did do quite a bit of testing for this at an earlier point.

So the harsh environment issues are mostly handled by ext3 journal-based recovery. For problems not fixable with ext3's journal-based recovery... cannot (currently) be fixed by fsck as dsd writes. At least that's what we found so far. Given those findings, it fell in our priorities list, and there is harsh competition there! :-) Now, fsck and our choice of FS are not frozen in stone, so help is welcome on this track.

legousbtower kernel module
Hi, I'm trying to connect a LEGO RCX via the RCX 2.0 USB Tower. When plugging it in, it gets listed with name and vendor in the messages log. However, /dev/usb/lego0 is not created. The corresponding udev rule is installed by Fedora's nqc rpm, but it relies on the legousbtower kernel module. AFAICT, it does not work because legousbtower.ko is missing. This is both on an XO-1.5 (11.3.0) and a 1.75 (11.3.1). The latter at least creates an entry in /dev while plugged in, but it's a generic usb one. On the former I don't see any dev node created when plugging in. Am I doing something wrong, or is it really just that the OLPC kernel is missing that module? If so, where can I get it? Or do I have to try compiling myself? Thanks! - Bert - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
