devolo-dlan-cockpit-4.3.3 with gentoo

Recently I have found out, that the version 4.2.3 of devolo-dlancopit, for which I have posted a gentoo ebuild in the article devolo-dlan-cockpit-4.2.3 with gentoo, does not work fully anymore. It fails  downloading firmware updates for the Devolo dlan 1200 PowerLAN adapters. Most probably the download urls for firmware updates have changed recently.

Devolo offers the application devolo-dlan-cockpit for download. The main purposes of devolo-dlan-cockpit are:

  • Firmware upgrades for the network adapters
  • Monitoring the performance
  • Configuring the network adapters

Firmware upgrades are more or less plug and play. One has to click the Updates-Button and everything else happens automagically. Monitoring the network performance with devolo-dlan-cockpit is of major interest, since it allows one to try out different wall sockets for better performance with nearly zero efforts. If one gets poor performance it can be of major impact just to use another wall socket in the same room.

Dlan-cockpit is available for most common operating systems. However, the only Linux distribution, they support right now is Ubuntu Linux. Most probably, the package will also work with Debian. Allthough these are binary packages, the application can also be used with Gentoo Linux. For this two binaries have to be executed /usr/bin/devolonetsvc, the service daemon and /opt/devolo/dlancockpit/bin/dlancockpit, the frontend application which depends on the service. Usually devolonetsvc is being started by an initrd script, but the one included in the package is not going to work with gentoo, so just start it manually as root user. If one really needs it that often, an own startup script or systemd configuration can be written. Below you can see a screenshot of the application.

The Gentoo way

For gentoo users here is my overlay including the updated devolo-dlan-cockpit ebuild: devolo-dlan-cockpit-4.3.3_overlay.tar.gz (39). It also contains an adobe-air-runtime ebuild as necessary dependency. The adobe-air-runtime ebuild has been taken from steam-overlay. Download the overlay and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge devolo-dlan-cockpit and update your dlan adapters again using your gentoo box.

devolo-dlan-cockpit-4.2.3 with gentoo

Recently I have started using Devolo dlan 1200 PowerLAN adapters. With these one can get a network with up to 1Gbps without having to install additional wires by using the power lines. Of course the 1Gbps are optimum values under perfect conditions. Practically one gets 100 Mbps to 600 Mbps, but this is enough for most purposes.

glsldevil binaries

About one year ago I wrote about the OpenGL/GLSL debugger glsldevil in the article gentoo ebuild for glsldevil-1.1.5 and provided a gentoo ebuild for it. Unfortunately glsldevil seems not to be available anymore from the web page of the University of Stuttgart (http://cumbia.informatik.uni-stuttgart.de/glsldevil/), which has rendered the ebuild useless.

Edit 29/5/2012: The original download site of the University of Stuttgart is available again.

Since the license of glsldevil  permits redistribution, I decided to upload my local copy, to make glsldevil available for the public again. Unfortunately this only includes the Linux binaries (32bit and 64bit) and neither Windows binaries or the source code.

You can download the Linux binaries from here: glsldevil-1.1.5.tar.gz (1847)

For use with the ebuild, just copy the file to /usr/portage/distfiles/.

zen-sources-3.2 with tuxonice

Starting with the 2.6.36 kernel, tuxonice has been removed from zen-sources. The latest official tuxonice patch, that is available at present, is for the linux kernel 3.0. In the meanwhile more recent patches, for kernel version 3.2.1 and 3.2.10, have appeared at crow202.org. So I patched the zen-stable-3.2 sources with the 3.2.1 tuxonice patch from there.

Suspend to RAM works with this kernel, at least on my Dell Precison M65 and my Desktop, as well as suspend to disk does. Furthermore I can confirm, that the 3.2.1 patch also works on the x86_64 architecture.

To get things to work, download the zen-stable-3.2 kernel tree from zen-kernel.org and extract it. Afterwards download the 3.2.1 tuxonice patch from crow202.org and apply it. After applying the patch you can continue with the standard kernel building process. As with zen-sources-3.1,  no additional patch is necessary for the zcache feature, the fix is already included in zen-stable-3.2. The zcache feature doubles RAM efficiency while providing a significant performance boosts on many workloads. The zcache feature is located under staging drivers in the kernel tree and depends on the cleancache feature, which is located under processor types and features. To enable the zcache feature, you have to pass the zcache keyword to your kernel, in example in your grub.conf.

Example: kernel /bzImage panic=60 root=/dev/hda3 zcache

For Gentoo users there is a more easy way: Download my modified overlay from zen-sources-3.2.tar.gz (918) and extract it in /usr/local/portage. The overlay contains all necessary patches. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

If you want to use tuxonice include tuxonice in your USE-flags. Then emerge zen-sources and build the kernel as you like.

Tuxonice is not officially supported in current zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org. You are on your own.

For my Precision M65 I used the following kernel config: config_zen_3.2_dell_m65.zip (925)

For more information on the zen-sources patchset see www.zen-sources.org.

zen-sources-3.1 with tuxonice

Starting with the 2.6.36 kernel, tuxonice has been removed from zen-sources. The latest official tuxonice patch that is available is for the linux kernel 3.0.  However, I found a more recent patch at gmane.org. So I patched the zen-stable-3.1 sources with this tuxonice patch.

Suspend to RAM works with this kernel, at least on my Dell Precison M65 and my Desktop, as well as suspend to disk does.

To get things to work, download the zen-stable-3.1 kernel tree from zen-kernel.org and extract it. Afterwards download the tuxonice patch from gmane.org and apply it. After applying the patch you can continue with the standard kernel building process. This time no additional patch is necessary for the zcache feature, the fix is already included in zen-stable-3.1. The zcache feature doubles RAM efficiency while providing a significant performance boosts on many workloads. The zcache feature is located under staging drivers in the kernel tree and depends on the cleancache feature, which is located under processor types and features. To enable the zcache feature, you have to pass the zcache keyword to your kernel, in example in your grub.conf.

Example: kernel /bzImage panic=60 root=/dev/hda3 zcache

For Gentoo users there is a more easy way: Download my modified overlay from zen-sources-3.1.tar.gz (872) and extract it in /usr/local/portage. The overlay contains all necessary patches. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

If you want to use tuxonice include tuxonice in your USE-flags. Then emerge zen-sources and build the kernel as you wish.

zen-sources ebuilds now with tuxonice

Starting with kernel version 2.6.36 tuxonice has been removed from the zen-sources patchset, the high-performance linux-kernel for desktops. With the new zen-sources-2.6.38_p20110510 ebuild the maintainer of the zen-sources ebuilds started to include tuxonice into the zen-sources ebuilds in gentoos portage tree.  Now the reliable suspend mechanism, tuxonice is known for, is again easily available on genttoo systems with zen-.sources.  Thanks Markos!

A Gentoo user now can choose if he wants to have zen-sources with tuxonice or not. To get zen sources with tuxonice one just has to include the tuxonice USE-flag into his /etc/make.conf and emerge zen-sources afterwards. Then one has to configure and compile the kernel as usual.
