Awesome. I think for this issue, you ought to make a thread so it gets to a wider audience, or folks who don't visit this thread.

Blessed be!

Greetings!

I'm fairly new to kernel compiling, but I've done it before and had no problems with it until now when I decided to return to gentoo and I started installing it on my laptop and my main machine.
The problem is that, the config is not saved or something.
I use make menuconfig, load the seed file from Pappy, make the changes, exit the menuconfig, it asks me to save the config again as ".config", I select yes and it exits.
Now when I try to build it, I get a no rule exception, telling me that there is no config file.

I might be doing something wrong, but I remember that these were the proper steps to take.

Thanks!

Thanks for a great site, Pappy:

http://62.3.120.141/~pappy

It's an excellent insight into the Linux kernel.

If the file is named config, that won't work. The source code only recognizes the existence of .config when creating the kernel itself. Check /usr/src/linux. If you can see "config" then it's wrong. You should only see .config or .config.old.

Blessed be!

For the next couple weeks, there may be issues with the site. I am going to be putting up my own server later on this week, and transferring the seeds site to my own machine. There may be issues with where the seeds currently reside as well.

At this point, I don't foresee any issues with the setup for my server. Famous last words,eh? I will keep all and sundry posted. Also, I will be uploading new seeds later this evening.

If there are issues, just request the seed version, and whether you want x86 or x86_64 via Gentoo private message, and I'll send it on its way.

Blessed be!
Pappy

Way later it seems...

As previously announced, I have just uploaded new .configs for 2.6.30-gentoo-r5 and 2.6.30-tuxonice-r5. I am almost finished updating the settings for the flowers. As soon as that's done, then it's time for production. Hopefully, this coming weekend will greet me with 47 years of life *happy b'day to me*, a server serving the seeds, and updated settings for the seeds.

Whew, that's going to most likely be a lot of work.

Blessed be!
Pappy

feliz cumpleanos ya old fella

finally rebuilt the server from one of the hardened x64 seeds (2.6.28-r9) - pruned my original non-seed kernel from 4.1MB down to 2.9MB

only up 12 minutes, but unsurprisingly, it works without issue. Finally starting to look like a healthy stash; I should have doc'd more of the configs done for folks on the forums based upon your seeds + guides, I'd chunk em on there as well.

EDIT: link removed. In hindsight, looks too spammish. Anyone with an Asus M3A78-T && hardened-sources, holler, I have my setup doc'd

Another day, another couple of .configs. I have just uploaded .configs for 2.6.27.30 and 2.6.30.5 in both x86 and x86_64 flavors. Enjoy.

Blessed be!

And somehow, I didn't update the html beforehand. Oops. Anyway, I have uploaded the .configs for 2.6.27.31 in both x86 and x86_64 flavors. Enjoy.

Also, it looks like getting up my own server is going to have to wait for later next week. Lots of projects, only one me.

Blessed be!

As a bit of a birthday gift to the rest of y'all, I have set up a special .30 kernel especially for x86 and x86_64 users with >=i915 GPU's. After a weekend of experimentation, I have set up what seems to be the most stable option for surviving the fun of KSM and other Intel GPU issues. I would like some verification from other Intel GPU users as to whether this improves stabilty; most specifically that it:

1. allows X to exit without a serious crash.
2. allows X to restart without any errors.
3. that the above steps can be taken at least five times without X failure.
4. that it works with >=xf86-intel-video-2.7.0
5. that it works with >=xorg-server-1.5.3

If this does work, then the version 7 .configs will be set for this by default. Users of other video chips will have to turn the options off. Please try this and let me know in the next few days.

If you are using other .30 versions, simply copy the .config to the kernel source directory and issue make oldconfig before make xconfig, or whatever you use to configure your kernel.

x86
x86_64

Blessed be!
Pappy

hrmmm

I nearly meet that

Code:

laptop02 linux # lsmod |grep i915
i915                  193800  2
laptop02 linux # equery list |grep xorg-server
x11-base/xorg-server-1.5.3-r6
laptop02 linux # equery list |grep xf86-video-intel
x11-drivers/xf86-video-intel-2.6.3-r1


Happy to test, but

-I need to update my xf86-video-intel
-I don't use KMS (happy to do a build that includes it, though)
-I don't have any issues to begin with, but, my session is all handled via xdm=>Entrance (E17). Would giving a few restarts to xdm periodically after heavy usage be sufficient?
-I should be able to quickpkg my xf86-video-intel and revert easily enough, yes?

I have the hardware you need for testing this, and the time. Just want to make sure a)my testing method is sufficient, b)it's not going to be a huge PITA reverting to 2.6.3-r1

See how things work with what you have if you're using a .30 kernel. I don't use or advocate the use of KMS. You know that. :) I am just looking to see whether or not it's stable...or more stable than what you were using.

Am on a .30-r4 built from your x86_64 seed :)

And well, it's awesomely stable far as i can tell.

Should I grab the new new one? Test with KMS or leave it out?

Easily done, don't mind changing things around.

EDIT: nevermind, re-read what you said

I'll snag the new seed, build with KMS, test, update xf86-video-intel, test. It's really no hassle to do all of the above.



EDIT 2: Did a diff of the two with meld, thinking maybe rather than reconfiguring from scratch I can add things in by hand.

Code:

<file system stuff>

<= # CONFIG_X86_VERBOSE_BOOTUP is not set

<= CONFIG_CRC16=m
   => CONFIG_CRC16=y


Potentially significant:

Code:

<= # CONFIG_MODULE_FORCE_UNLOAD is not set
<= # CONFIG_FREEZER is not set

   => CONFIG_AGP_INTEL=m
<= CONFIG_DRM_I915=y
   => CONFIG_DRM_I915=m
<= # CONFIG_LCD_PLATFORM is not set
<= CONFIG_DMADEVICES=y


Hrmm...doesn't look too daunting just changing those few bits.

As long as it's stable, that's my concern. In the new versions of the seeds, I am setting this option for all .30 kernel versions. Those who don't have Intel GPU's simply turn off intel-agp, or if it is needed, turn off the Intel DRM settings, whichever leaves you with the ability to use another video card. This is to be done as a courtesy to the people with Intel GPU's. The amount of troubles that have been reported made me realize that something needed to be done to make all the problems with the latest kernel versions go away, at least for Intel GPU users.

Anyone else interested, please give it a try. They are like any other kernel seed, but they are preset for stable Intel video operation. Change the settings as per the instructions at the kernel seed page, but don't mess with the graphics settings at all. Then report your findings.

Thanks again.

Blessed be!
Pappy

At long last, the flowers have bloomed. The version 07 .configs have just been uploaded. I will upload the html code to put the site up as soon as I post this. Here is a list of the changes with the version 07 kernel seeds:

  • mainline support for >=.26 kernels only
  • turned off ipv6 support
  • turned off forced module unloading
  • lowered Maximum number of legacy PTY in use to 64 devices
  • turned on DMA Engine Support
  • turned off Large single file support
  • turned off PID device support
  • turned off file system extended attributes
  • turned off CIFS extra settings
  • turned off NFS client support for the NFSv3 ACL protocol extension
  • configured .30 kernels for stable operation with Intel GPU devices
  • much greater consistency

As far as configuring the .30 kernels for better Intel GPU operation, I continue to read and comment on threads concerning X instability with >i915 GPU's. I do this as a courtesy to the Intel GPU users out there who continue to bounce on the sea of Intel drivers, patches, and kernel patches, yet can't get X to work. Other Video card users need only turn off the Intel AGP, or if that's needed, the Intel DRM stuff. All machines should boot with VESA VGA, which has always been the default frame buffer for my seeds.

Questions and comments are, of course, welcomed.

Blessed be!
Pappy

Hi Pappy.

I have got one little concern and I think it's due to the kernel. I have reported it in another thread. I seem to experience short audio drops whenever I'm listening to audio files, either through the network or locally. These drops always occur with disk activity. Someone in the thread I pointed to kindly helped but didn't find anything special about that. Do you have any guess as to where to start searching?

Cheers.

Is it one particular program, or many? What audio device? What kind of system?

Blessed be!

I see by the calendar that hangs out on the far right side of my lower panel that it's almost the one year anniversary for Pappy's Kernel Seeds (09-12-2009). Nice! Got to love it! I don't have anything planned for that day. It would be cool if a new kernel version came out or some such. But, I'm not holding my breath that it will be anything other than another busy day.

Other than that, I have finally uploaded the .configs for 2.6.30-gentoo-r6 in both x86 and x86_64 flavors. Enjoy!

Blessed be!
Pappy

hey pappy, thanks for all the hard work. i've been using genkernel for months before I finally decided to jump into building my own kernel, and your seeds helped me get a headstart. I'm in debt to you. :) you're an inspiration.

Hello,

I will take a look at your seeds for my desktop and laptop. My kernels are too big IMHA.
Big ups, Pappy !

Nice work pappy. Had these seeds been around 6 years ago, the old P3 powered Compaq I was using may not have ended up in the trash after numerous fail to boots followed by a kernel panic..

Thanks, one and all.

I survived this last bout of production, and I am quite happy with the results. I have so far only found one particular misconfiguration. It was minor, and it has been repaired. That .config and it's "children" will be resent soon.

Other than that, it seems like it was sell off everything day at http://kernel.org. I have lots and lots of new .configs uploaded and waiting. I have uploaded .configs for 2.6.27.32, 2.6.27.33, 2.6.30.6, and 2.6.31 in both x86 and x86_64 flavors.

I will be testing out the .31 kernel in the next few days to see if it will benefit from me setting up for Intel GPU's, like I am in .30. It's on my todo list.

Blessed be!
Pappy
