Rapid DHCP
Here's an article that tries to explain why Mac OS is so much faster at connecting to networks than Linux and Windows: http://cafbit.com/entry/rapid_dhcp_or_how_do Could such an implementation be considered for the OLPC OS? XOs go on and off the network all the time, as power management kicks in and the machines move in and out of AP range (or switch to a different AP). This is a disruptive process, and speeding it up would be welcome. Sridhar Sridhar Dhanapalan Engineering Manager One Laptop per Child Australia M: +61 425 239 701 E: srid...@laptop.org.au A: G.P.O.

Re: Removing linux-firmware from the build
On Thu, Jul 28, 2011 at 4:38 PM, Daniel Drake d...@laptop.org wrote: Hi, linux-firmware, the package that puts lots of stuff in /lib/firmware, is growing and growing and is mostly irrelevant for us, including firmware for (e.g.) SCSI controllers. I'm considering removing it - nothing in the XOs uses firmware from that package. (our wireless firmware comes from other packages) The question is, do any external devices used by our users pull on firmware from this directory? Browsing the contents, I doubt it, but I thought I'd ask anyway. I may also just remove it from the builds as an experiment, see if anything breaks. The devices that come to mind for me are serial adapters and wired ethernet adapters. I don't have mine handy but I have a OLPC serial adapater plus a pair of usb eth adapters that I use regularly on the XO that all need firmwares. Nothing else races to mind.

Re: 11.3.0: Share repos across arches -
On Thu, Jul 28, 2011 at 7:29 PM, James Cameron qu...@laptop.org wrote: We currently sort them by placing them in a dropbox according to the XO model, and use the model-specific dropbox in olpc-os-builder. (The firmware build scripts handle this in the copyme step). Right - but I think this is is a poxy setup. 'arch' would not be sufficient for XO-1 vs XO-1.5 selection, since the hardware has the same 'arch'. True. I propose: I generally agree with your proposal, except that I've now come around to think maybe it's a pile of pointless work, as it only shifts things around, no clear benefit. We can just setup an xo-1.75 repo for the relevant bootfw and be done with it. There's more interesting stuff to handle.

USB2VGA2
DSD: Hello good sir: I'm back from Kenya and ready to continue the troubleshooting on the SISUSB front. To reiterate: 1) on 11-2/874, my USB2VGA and USB2VGA2 adapters with external monitor always works on a 1.5 2) on 11-2, any build, on an XO-1. out of 100 tries, system virtually always 'hangs'. One of them booted up once - still didn't show a picture, but it did boot. Rest of the times they would hang at the v - one dot point or three dot point of the animation 3) on 10-3/860 on those same XO-1's, the adapter and ext screen always work. What this tells my litle grey cells, is that a) it's probably not firmware, since the firmware is the same on those XO 1's whether Ive flashed them to 860 or 874. and b) since it works on a 1.5, it's not an fc14 thing. The devil is in the middle there somewhere :-) I had left the XO-1 on after an attempted boot with the USB2VGA adapter plugged in, yep two weeks. When I got back there were a couple of udev messages on the ctl-alt-F3 screen which I will forward to you if you think they might be of value. Mentioned upcoming deprecation of 'STAT' etc. FYI, I do all this work without doing any customiaztion. These are vanilla, virgin, 4-game key flashes using original images. None of my deployment funny stuff. I did read that Sameer had been successful getting an XO-1 to come up on 873; but he used olpc-update, so I might try that too, just to see if maybe some working x thing is persisting that makes it all happy. Since I forgot to do that little dump thingy you had asked me to do before sending the log from the serial adapter, I will do that over the weekend. sigh So a rather long introduction to short question: should I now be testing these beasts using os1 on 11-3 instead of on the already released 11-2 ?? BTW all the machines at our Kenya deployments are running 11-2. We will get any issue reports and forward them up the chain. There are anecdotal complaints that the trackpads and keyboards are locking up more frequently than on 802, and that certain build-provided activities that worked flawlessly on 860, are doing a 'fail-to-start' on the first, second and sometimes even once in a while on subsequent attempts. However, all this is currently anecdotal rather than scientific reports. Last but not least, as you may remember, we do install some extra software on the machines using yum --downloadonly while here in Canada to get the RPM's to a USB stick, then in Kenya do a yum localinstall there to be more efficient with teh sometimes slow, and always expensive data time. On the XO 1.5's, all goes well with everything installing nicely. On the XO 1's, I get a lot of '...was supposed to be installed but was not' messages. However, it would appear that indeed the rpms did get installed. The google-verse seems to indicate this might be a permissions issue. All the software seems to run fine, and any attempt to reinsall sys 'Nothing to do' as the package doesnt update the existing one. Weird. And, there is a 'RPMDB was modified outside of yum' message when subsequent installs are tried. Again everything seems to 'work' but the messages are a little troubling. Again, no such messaging on the 1.5's. That's it from here for now. I await your wishes on 11-3 versus 11-2 for the USB2VGA.
