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 (774) 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 (781)

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.

zen-sources-3.0 with tuxonice

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.

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: linux-3.0-zcache-fix.patch.bz2 (844) 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 zen-sources-3.0.tar.gz (703) and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

module parameters changed in kvm-intel

With linux kernel 2.6.32 module parameters for kvm-intel changed so if you cannot load the module anymore and you get errors in dmesg like

kvm_intel: Unknown parameter `enable_vpid’
kvm_intel: Unknown parameter `enable_ept’
kvm_intel: Unknown parameter `flexpriority_enabled’

you should update your module config. For gentoo users this means to edit the file

/etc/modules.d/kvm_intel

and to remove the obsolete parameters. Afterwards run

update-modules -f

Now you should be able to load the module and do kvm vitualization again.

For me this problem occured when trying the new zen-sources-2.6.32-zen1 (also in zen2). Sadly this kernel is affected by the bug which causes higher power consumption (at least on my Precision M65) when not running a suspend to ram cycle before. This also occurs with vanilla sources. For more information on this topic see bugzilla.kernel.org.

zen-sources-2.6.31-r2 with tuxonice

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: current-tuxonice-for-2.6.31-zen1.patch-20090911-v1.bz2 (933). Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from zen-sources-toi-2.6.31-r2.tar.bz2 (883) 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: kconfig_zen-sources-toi-2.6.31-r2-precision_m65 (806)

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.

zen-sources-2.6.31-r1 with tuxonice

Today I patched the  new zen-sources-2.6.31-r1 with tuxonice. This time it was a bit more complicated since the two patches are conflicting. So I modified the tuxonice patch to apply cleanly over the zen-kernel.

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-zen1 patch here: zen-sources.org. Then apply the patch to vanilla kernel sources. Afterwards download my modified tuxonice patch from here: current-tuxonice-for-2.6.31-zen1.patch-20090911-v1.bz2 (933). Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from zen-sources-toi-2.6.31-r1.tar.bz2 (860) 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.

To work around the black screen problem with some nvidia-drivers versions occuring with 2.6.30 kernels, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Most probably this problem persists with 2.6.31. Strangely the issue did only occur on my Precision M65 with a Quadro FX350M. It did not occur with the Quadro FX3400 in my Desktop PC, Nvidia-drivers-185.18.31 are running there without any problems.

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: kconfig_zen-sources-toi-2.6.31.1-precision_m64.zip (760)

If you want to use all channels with the iwl3945 driver change the line static char *ieee80211_regdom = “US”; to static char *ieee80211_regdom = “JP”; in the file net/wireless/reg.c.

If you also own of those old 16 Bit Adaptec pcmcia scsi cards using the aha152x_cs module you might want to enable it also for 64 Bit kernels. It was masked for 64 Bit kernels somewhere before 2.6.13. I was unable to find out the reason for this so I tried to compile the module. When I insert the card, the module loads properly. Since the drive I could test it with, is currently attached to another box and in use, I can´t try it out for the moment. Once I tried I´ll keep you updated.

To enable the driver remove the line

depends on !64BIT

in the config PCMCIA_AHA152X section in /usr/src/linux/drivers/scsi/pcmcia/Kconfig and select the module in menuconfig.

Addon: I tried a SCSI cdrom with this and it works perfectly. I just filed a bug on this on bugzilla.kernel.org and hope for the driver being unmasked for future  64 Bit kernels.

If you are using this kernel on a notebook with i.e. a Core2 CPU you might be interesting to undervolt your CPU to save power and to produce less heat (keeps the fan off longer). This works like a charm on my M65. Information on this topic can be found here: aldeby.org. The linux-pch patch mentioned there is already included in zen-sources, thus you only have to perform the userspace part begnning at (3).

For image compression in tuxonice include Compressor lzo in your suspend2.conf file.

Sadly the iptables mirror target I published here does not work anymore with the 2.6.31 kernel. A newer version will be available soon on mygnu.de.

zen-sources-2.6.30-r4 with tuxonice

Today I patched the brand new zen-sources-2.6.30-r4 with tuxonice. This was necessary since I need tuxonice on my notebook for suspend modes and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

I recommend using this version over using the r3-version, because it fixes the root exploit vulnerability mentioned on www.linux-magazine.com.

Download the zen-sources 2.6.30-zen4 patch here: zen-sources.org Then apply the patch to vanilla kernel sources. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/current-tuxonice-for-2.6.30.patch-20090620-v1.bz2 and apply it.

For Gentoo users there is a more easy way:

Download my modified overlay (including the patches) from zen-sources-toi-2.6.30-r4 overlay (788) 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.

To work around the black screen problem with some nvidia-drivers versions, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Strangely the issue does only occur on my Precision M65 with a Quadro FX350M.

For my Precision M65 I used the following kernel config: kconfig-precision_m65-zen-sources-toi-2.6.30-r4 (769)

If you want to use all channels with the iwl3945 driver change the line

static char *ieee80211_regdom = “US”;

to

static char *ieee80211_regdom = “JP”;

in the file net/wireless/reg.c.
