Bits from the Debian Eee PC team, autumn 2008

Some brief highlights of the last three months of Debian Eee PC development.

Thermal and ACPI breakage resolved in 2.6.26-7

We’re pleased to see that in the upload to Sid of linux-image-2.6.26-1-686 version 2.6.26-7, the pair of 2.6.26 bugs we’ve been tracking that have made it difficult for Eee users to upgrade their systems have been resolved. Since then 2.6.26-8 has been uploaded and is expected to enter Lenny this week due to a freeze exception. Once the new kernel has migrated we will move quickly to build and release a new installer that includes it.

Ath5k wifi works on Eee PC in Linux 2.6.27

Jean-Christophe reports that ath5k works in Linux 2.6.27 on the Eee PC 701, and just needs a small patch to work with our eeepc-acpi-scripts package. This is good news for those of us with models 701, 900, 900A and 1000HD who have been wanting to get off of the non-free Madwifi drivers and onto DFSG free drivers.

New Eee PC model 701SD wifi support in the works

Users of the new Eee PC Model 701SD have just started showing up looking for support in mainstream Linux distros. Martin Filtenborg confirmed using our Eee PC Live image with the GPL’d rtl8187se driver from Realtek that we can at least use it to connect to an unencrypted AP, get an IP address and ping other hosts.

Of course, it is one thing to have a working vendor-supplied driver and quite another to have mainstream support. We’ll make do with what we have now, but will be seeking a mainstream solution as soon as possible.

We’re seeking more testers and developers to work on this. To date, an ITP has not been filed, as it is not yet clear who is going to carry this work forward.

Chasing the 5 second boot

An interesting discussion on Arjan van de Ven and
Auke Kok’s work to get an Eee 901 to boot in 5 seconds took place this month. While the Debian Eee PC team is not making work on this a priority, we’ll keep an eye on it to see if Debian can incorporate some or all of the techniques they used so that our users can benefit without making radical changes to their systems.

Working towards mainstream support for rt2860

Our filing of an ITP for rt2860 (the wifi driver for models 901, 1000 and 1000H) was followed by discussion about how to separate out the GPL’d driver from the embedded non-free firmware so that it can at least go into contrib. Glenn Saberton has been working on rewriting the build system around kbuild and separating out the firmware.

Numerous improvements to ACPI scripts

Since my last progress report, there have been numerous improvements to the eeepc-acpi-scripts package to deal with all of the various models we now support and make the scripts more robust and flexible. Check out the changelog for details.

Bits from the Debian Eee PC team

Saturday, February 16th, 2008

In the past few months in the Debian-EeePC team, a number of interesting things have been happening.

Progress has been made to ensure the Eee’s drivers get merged upstream. Chris Snook from Red Hat has taken over atl2 upstream and has started merging it with the atl1 driver to make a unified atlx driver that will be suitable for inclusion in the kernel. As well, there is continued progress on the madwifi driver, with a patch now included to support version 2.6.24 of the Linux kernel.

In the meantime, the Debian Eee PC Install HowTo has been under constant revision, even gaining recently the beginnings of translations in French and German.

ACPI, another important piece of infrastructure for the Eee, is now supported in lenny and sid through Eric Cooper’s eeepc-acpi kernel module. This is a fork of the asus-acpi module renamed so that it won’t conflict with the in-tree version. It turns out that asus-acpi is deprecated, having been replaced by asus-laptop. Eric has been in touch with the asus-laptop maintainer to ensure the Eee-specific bits are merged so that we can eventually retire our forked version.

There still remains at the top of our Todo list the issue of ACPI scripts to go with the kernel module. Having at first considered patching acpi-support, we have decided instead to start with Eric’s own scripts which will be packaged shortly for Debian. This gives us more freedom to tinker before considering submitting patches to more general laptop support packages like acpi-support.

Finally, after Brendan M. had to send his Eee back to Asus for repairs, work stopped for a while on the custom debian-eeepc installer. Fortunately, he just got his system back from the shop as good as new and has returned with renewed vigor to that task. He has produced a new version of the installer which we are now testing.

Thanks to the efforts of numerous users and developers who are being added to our ranks daily, we expect by the time Lenny releases we will be well on our way to providing a pure Debian solution for the Eee. Whether or not everything needed for the Eee is in Lenny at that time remains to be seen. We need to allow for how long it takes to get new drivers into the kernel. But if we miss the release, we will certainly provide backports and look forward to full support in the following release.
