1. We are very happy to announce the availability of a new stable build. It is composed of Build 368 and the Q2B85 firmware. The highlights of this build:
We've made a decision to use the AMD Geode LX for the mass-production machine!
* a working mesh network;
* a user interface to the mesh network;
* a working battery charging;
* a battery indicator in Sugar;
* an greatly improved web browser;
* many other activity improvements;
* a substantially improved boot time;
* availability of Helix Media Player (Real Networks);
* instructions for customizing your own image.
There is also a content library included in a separate package.


2. laptop.org: We are using the wiki as our content management system and the infrastructure for translation is now in place. Thanks to the tireless efforts of [[User:Xavi|Xavier Alvarez]], the first translation of the new website is on line (See http://www.laptop.org/es).
1. A team including Chris Ball, Mitch Bradley, Jordan Crouse (AMD),
Matthew Garrett (Cambridge), Andres Salomon, Richard Smith, David
Woodhouse, Tom Sylla, and Marcelo Tosatti succeeded in the initial
"bring up" of suspend and resume.


3. Wireless: This week was marked by five releases of wireless firmware, setting a new record. Today, we are at Firmware 5.220.10.p5, which fixes or addresses all known issues. Many thanks to Dan Williams and Marcelo Tosatti from Red Hat, the Cozybit team, the Marvell team, and Michail Bletsas.
2. São Paulo: David Cavallo gave a talk at the Catholic University of
São Paulo (PUC-SP). The majority of those attending were people from
the education and technology program, the curriculum program, the
program for indigenous education, and the mathematics department.
Included in the group were former colleagues of Paulo Freire, who
maintain the Freire House at the university. The discussion among
people who have worked long and hard for education reform and equity
was excellent and pragmatic, focused on learning from the difficulties
of the past.


Dan and Chris Ball helped John Watlington build a kernel with the Libertas driver for his school server machines with Marvell USB dongles plugged in; the school servers now function on the mesh.
3. Sugar: Everyone on the Sugar team is working toward an
end-of-the-month deadline. Over the last two weeks, Marco Gritti,
Tomeu Visoso, John Palmieri, Dan Williams, and the Abiword team have
made numerous improvements to the interface.


Michail expanded the OLPC mesh testbed to 22 nodes, which allows for more conclusive scalability tests (and starts to become a full-time sysadmin job). Dan hooked up the UI for the mesh view to make it possible to join the wireless mesh easily. Thus, this week was the first time that we have really been able toget a sense of how the mesh will work as an end-user experience, and it has to be said: it is really good. Boot a system for the first time, and if the machine sees a mesh, “poof,” you're on the network. Really quite remarkable.
For Sugar itself, the frame behavior is getting much better—we have
made changes based on feedback from the field. Specifically, the
heuristics for when the frame is shown and hidden automatically are
much more consistent. Rollovers have a much better feel to them and
many random performance problems have been fixed.


4. Sugar: Marco Gritti spent a lot of time cleaning up and finishing last minute issues in the build. Some of the new fixes in Sugar are based on feedback from the field. This includes avoiding multiple launches of an activity; immediate feedback for launch; much improved frame behavior; and better overall performance. Marco also fixed bugs in the web browser that were preventing Google talk and some other sites from working. The dots-per-inch (DPI) scaling code in Mozilla still has issues; we will continue to work through them as we find them.
The team also spent time setting up activity file dialogs; this
includes saving entire web pages, images from web pages (from a right
click), saving and opening inside the document editor, and the image
editor. While file dialogs will eventually be supplanted by the
Journal, it helps with usability in the short term.


5. Tomeu Vizoso and Marco also added support for localization for Sugar (and some of the activities). Although we won't have any languages other than English in our first build, we should have the ability to start translating: the infrastructure in the programs in now place; next we need to set up a place for people who want to localize to participate. SJ Klein has set up a list on laptop.org for people who want to translate, which is a good start.
Abiword now supports image loading and floating the images anywhere in
a document. This should let kids create their own documents based on
images they find on the web.


6. Battery: We know battery problems have been a great pain and concern and we are relieved that they have finally been resolved. For those of you with dead batteries with B2 systems, most, but not all of the dead batteries can be recovered with the systems you now have with the new firmware. Recovering batteries in the field with B1 systems is harder; thankfully there are far fewer B1 systems deployed. Please follow the directions in [[Battery Charging]]. We would like to thank all those who helped in the resolution of this problem, in reports from the field, and at Quanta and OLPC. Special thanks to Richard Smith, who was relentless in his efforts to chase down numerous bugs in the embedded-controller code.
Marco and Tomeu have also started adding support for
internationalizing those few text strings that do exist in the
interface. SJ Klein is organizing a team of people interested in
helping with the translations.


7. Please update your systems to the new firmware as this firmware also fixes a battery overcharge problem.
Dan has been integrating the mesh functionality into Network Manager.
This includes fixing problems in the driver, adding new functionality
to Network Manager, and creating the user interface to support it.
Pentagram has been iterating on a design for visual feedback for the
various network states and modes.


8. New activities as of Build 368:
We are approaching a stage of stability in development such that we

need to seriously investigating how to enable a wider network of

xbook (PDF viewer) as an activity.
the latter, we are going to build images that people can download and
run in emulators that are available for just about every platform
these days. John will be working more on this over the next week.


9. Multimedia: Real Networks and the team at the Open Software Lab at Oregon State University have been working on a multimedia platform for the laptop.
4. Suspend/resume: Chris Ball measured resume time at 900ms with
(See [[Helix Media Activity]]). This is able to handle most common audio/video datatypes, as Real Networks has codecs for almost anything you can think of. The commercial version is better known as “Real Player” (Justin Gallardo (OSU), Greg Wright, Jeff Dutchman, Martin Schwartz (Real Networks))
drivers unloaded and 1400ms with all drivers loaded, according to the
kernel. Linux 2.6 currently performs a slow virtual-terminal switch on
suspend/resume, which may account for much or most of this delay we
will immediately eliminate this switch, as we don't need it. In
contrast, resuming conventional laptops running Linux on processors
many times faster than our system are measured at 6–12 seconds, so we
are already many times faster than most systems. Both the power-draw
numbers and suspend/resume-time numbers will head downwards as we
start optimizing power management. Mitch Bradley has measured the
firmware resume time of approximately 25 milliseconds.


10. Library activity: SJ has been leading a large community effort to build a content library for the laptop. (See [[Library Release Notes]] for a description formats we are using to display directories of books and other materials.) Next up is a focus on the school library, figuring out how it communicates with the XO and what processes need to run on each to provide updated indices and views.
5. Firmware: The firmware end of the suspend/resume code seems to have
held up well in this week's kernel testing. Lilian Walters did some
work on memtest86 so it can be integrated into the ROMs, giving us a
heavy-duty memory test capability that will always be available. Mitch
made good progress on the firmware port to the LX; the firmware is
interactive and he is now resolving MSR (model-specific register)
discrepancies. He expects to have a releasable OFW for the LX
development board soon.


11. Chris Ball created a procedure for customizing NAND images. Mitch Bradley has created a “save-nand” Open Firmware command to do this easily, but the

command will only be available in firmware versions Q2B84 or higher (See [[Customizing NAND images]]).
for the suspend/resume and power management work:

14. Power management: Jordan Crouse (AMD) reports suspend to RAM (STR) support is proceeding very well. After successfully resuming the system two weeks ago, this past week was spent diagnosing problems with the core drivers (namely, the framebuffer, the DCON, and the timer tick). Andres Salomon and Jordan discovered some serious DCON issues with source switching (from CPU to DCON source); those were traced back to firmware (after spending lots of time debugging the kernel) and Mitch fixed them there. We can now successfully freeze the frame on the DCON, and suspend and resume the system without losing the display. The timer tick was also fixed, which now means we don't need any special changes to the kernel command line to work around issues on the resume.
Andres updated our kernels to 2.6.21-rc4 (previously 2.6.21-rc2), and
merged libertas driver changes. Andres also cleaned up the MFGPT
(multi-function general-purpose timers) driver, as these are drivers
that we would like to get upstream.


Attention now focuses on handling the secondary drivers (such as the audio, camera and USB), and improving overall stability. Our target for power-management stability is 1000 consecutive suspend/resume cycles without a glitch.

to a full suspend/resume story.

All of the code we are using is now in the “powermgmt” branch of our kernel GIT tree.

15. System software: Andres also made the touch-pad driver much more tolerant of version numbers and merged more fixes into the Libertas driver. He also worked on preparing mfgpt/dcon/geode code for inclusion upstream.

16. School server: The school server development continues. We now have wireless mesh interfaces enclosed with an antenna and 3 meters of USB cable. Thanks to Chris Ball and Dan Williams, the server now recognizes them. Internet-router functionality is up and running (on the wired school LAN) and applications and content for the Library are starting to be installed. A school server specification—really more of an introduction—has been written and posted on the wiki.

N. Firmware: We are planning to cut all developers over to the fastboot/suspend/resume firmware next week. Lilian Walter released a few self-tests this week, including: nand-flash;
spi-flash; display; and camera (a new driver). Our goal is to aid field diagnosis and repair.

Lilian has also released code to reprobe the usb bus to remove obsolete device nodes and to create new device nodes as usb devices are removed, added or replaced. Next, Lilian shall look at keyboard self test and Quanta's request for modification to the NAND flash self test.

Mitch added the following features were added to that firmware this week:
* ability to do fast display save/restore in the low-level resume path (This feature is turned off by default, in favor of similar code in the kernel, but serves as a working model for how to interact with the hardware to accomplish the purpose);
* USB power state restoration after resume;
* self-test diagnostics (from Lilian) for several devices, including camera and display (The self-test suite is nearly complete now);
* save-nand command for creating restorable images of modified JFFS2 filesystems;
* a fix for an infrequent problem with reflashing the firmware; and
* a fix for a problem booting.

The OFW port to the LX development board is working, so OFW is on track for the switchover to LX.
