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 [download#84] 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: [download#85]

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.

Starting with the 2.6.36 kernel, tuxonice has been removed from zen-sources. The latest tuxonice patch that is available is for the linux kernel 3.0.  So I patched the zen-stable-3.0 sources with tuxonice. Hopefully a patch for more recent kernel versions will be available soon.

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-3.0 kernel tree from zen-kernel.org and extract it. Afterwards download the tuxonice patch from tuxonice.net and apply it. For getting the zcache feature, to work you have to download and apply this patch: [download#74] The zcache feature doubles RAM efficiency while providing a significant performance boosts on many workloads.  The patch has been extracted from vserver-sources-2.3.2.5 with working zcache feature.  After applying the patch  you can continue with the standard kernel building process. 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 [download#76] and extract it in /usr/local/portage. 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.

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.

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.

Starting with 2.6.36 tuxonice has been removed from zen-sources again. A few days ago the zen-sources-2.6.38_p20110501 ebuild appeared in the gentoo portage tree. So I patched the brand new zen-sources-2.6.38_p20110501 with tuxonice. The official 2.6.38 tuxonice patch from tuxonice.net has worked out of the box, this time.

Suspend to RAM works at least on my Dell Precison M65 and my Desktop, as well as suspend to disk does. Well, I have to mention that I again tried to use BFS, the brain fuck scheduler, to increase (felt) performance. This time the brain fuck scheduler worked well with tuxonice and did not result in the crash during atomic copy, I described in zen-sources-2.6.37_p20110325 with tuxonice.  Thus  I did not have to fall back to the CFS scheduler and automatic control groups as I had to with 2.6.37. However this is also an alternative to the brain fuck scheduler.

Download the zen-sources-2.6.38_p20110501 patch here. Then apply the patch to the vanilla kernel sources avalable from kernel.org. Afterwards download the tuxonice patch from tuxonice.net and apply it. Now you can continue with the standard kernel building process.

For Gentoo users there is a more easy way: Download my modified overlay from [download#69] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

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

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: [download#70]

Starting with 2.6.36 tuxonice has been removed from zen-sources again. A few days ago the zen-sources-2.6.37_p20110325 ebuild appeared in the gentoo portage tree.  Since I did not want to stick to my old 2.6.35 kernel I patched the brand new zen-sources-2.6.37_p20110325 with tuxonice. The official tuxonice patch from tuxonice.net did not work, so I had to slightly modify it to apply cleanly on zen-sources.

Suspend to RAM works at least on my Dell Precison M65 and my Desktop, as well as suspend to disk does. Well, I have to mention that I wanted to use BFS, the brain fuck scheduler, to increase performance. This resulted in tuxonice freezing during  atomic copy when trying to hibernate, thus I had to use the CFS scheduler again.

Download the zen-sources 2.6.37_p20110325 patch here. Then apply the patch to the vanilla kernel sources avalable from kernel.org. Afterwards download my modified tuxonice patch from here: [download#64]. Then apply it and continue with the standard kernel building process.

For Gentoo users there is a more easy way: Download my modified zen-sources-overlay (including the patches) from [download#65] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

If you want to use tuxonice include toi in your USE-flags. Then emerge zen-sources and build the kernel as you wish. It would be nice if this USE-flag and the ebuild modification find their way into the portage tree.

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: [download#66]

Today I patched the  brand new zen-sources-2.6.31-r2 with tuxonice. Again it required the modified tuxonice patch of my last ebuild.

Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Download the zen-sources 2.6.31-zen2 patch here: zen-sources.org. Then apply the patch to vanilla kernel sources. Afterwards download my modified tuxonice patch from here: [download#29]. Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from [download#33] 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 zen-sources-toi and buld the kernel as you wish.

Tuxonice is not officially supported in 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: [download#34]

All Information regarding the iwl3945 driver, the aha152x pcmcia scsi card and cpu undervolting in my last post on zen-sources-toi still apply to this version.
