Would you be willing to explain what have you done to set this option to work?

Easy: Full install
    You have to compile your own kernel with these options in "DOS/FAT/NT Filesystems"(kernel's .config file):
    Code:
    CONFIG_FAT_DEFAULT_CODEPAGE=850
    CONFIG_FAT_DEFAULT_IOCHARSET="utf8"

    Install and boot your kernel.

Hard: Full install, initrd.gz and pup_4xx.sfs edit, remaster LiveCD.

The kernel device modules are not shipped with libdrm releases and should only
be built from the git tree by developers and bleeding-edge testers of
non-Intel hardware. The Intel kernel modules are developed in the Linux
kernel tree.

So I have to download and compile drm-intel. Anyway, I have packaged everything else, download these files if you want [download from filefront]:
    libdrm-2.4.4git-i686.pet
    mesa-7.3-i686.pet
    drm-2.4.4-k2.6.27.5.tar.bz2
    xf86-video-intel-2.6.1-i686.pet (attached below)

Installation:
1. Switch to Xvesa (exit X and run xorgwizard)
2. Once in Xvesa, install: libdrm-2.4.4git-i686.pet; mesa-7.3-i686.pet; xf86-video-intel-2.6.1-i686.pet
3. Extract drm-2.4.4-k2.6.27.5.tar.bz2 to any folder (example: /root)
4. Exit X, go to the drm-2.4.4.-k2.6.27.5/ folder and run install.sh. Example:
Code:
cd /root/drm-2.4.4.-k2.6.27.5/
./install.sh

5. Install drm-intel modules. Pending... remember? maybe tomorrow...

iscraigh also will post a kernel request soon (I asked him to post it here, after he wrote a pm).

This should force us to overthink, if we should go for a new kernel, with all the new settings we need.

I would need for the new Ati catalyst driver:

Code:
#
# Bus options (PCI etc.)
#
CONFIG_PCI_MSI=y


If we decide to compile such a kernel, and build new isos then, we also might switch to a newer kernel release?
Or should we stay with the current one?
I was planning to try 2.6.29 in april, because it includes some new stuff for next xorg releases (dri2 I think, but I'm not certain, if it was called different).
Apart from that, I have no need of a new kernel release yet.
We also had to test, if the Ati and Nvidia drivers compile with it, especially nvidia 96 and 173.

What do you think?
Mark

iscraigh seems to be offline, so here I quote his request, before I go asleep:
--------------------------------------------------------------------------------

I have cobbled together a puplet based on the unamed pup for the Aspire one netbook. I still have a hardware issue with the sd card slots being recognized. Using some advice from other posting on the aspire one I was able to get the left card hotplugging but found I did not have the pciehp module.

Tempestuous suggested I ask you "very nicely" to enable it in the kernel.

Quote:
I suggest you ask MU nicely to enable this module in the 2.6.27 kernel configuration. It's at:
"Bus options (PCI etc.)" > "Support for PCI Hotplug"
this will then reveal an additional option above it called "PCI Express Hotplug driver"
This driver will not load automatically. The best way to load it at each bootup is by adding it to Puppy's "ADDLIST".


If this is not to much trouble I would appreciate it.

On that note assuming you are able to do this would I have to do the whole remaster again or could I mount the sfs file (is mounting an sfs rw possible) and swap in your kernel?

I am finding myself a little over my head I just made this for my kids and now people are using it so I feel I should try to keep it up.

As log as I am harrasing you Smile one more thing

Boot speed is slower on puppy than a full ubuntu install.

I see that sickboy from the kuki linux project has a kernel just for the aspire that is supposed to be fast, could I substitute that kernel? (It can't be that easy I am sure)

I just have a rough idea:

At startup, use the option:
pdev1=sda1

If you boot from CD, type at the bootscreen:
puppy pdev1=sda1

If you boot frugal, add in the end of the line that loads the kernel:
pdev1=sda1

Instead of sda1, use the name of the drive, where your savefile is located.
This avoids, that Puppy scans ALL partitions for a savefile.

If the delay happens BEFORE this part already, we had to look closer at initrd.gz.
We must look, if that part can be optimized.
I hope I have time for this at weekend.
In "init", there is a part, that greps dmesg for loaded drivers. If I remember well, this uses a delay/timeout.
Maybe this can be enhanced.
I boot some files from an external USB-harddisk, so maybe, this is faster that on computers without USB-drives, as they write different messages to dmesg.
I could setup a testsystem, that will completely load from my internal drive (a CF card replacing a harddisk), without other drives attached.

-----------------
Simply replacing a kernel is not that simple.
The problem is, that also the modules in initrd.gz must be replaced, and some files in /etc/modules.

Got home and was just going to post, thank you for posting for me.

I have tried the pdev tricks, as well as using pizzagoods advice on editing the initrd.gz config to not force a loading in ram of the pup save file. This trick sped boot up marginally. The slowdown seems to occure before it is looking for the pup save file.

I have tried a full install as well as a frugal, both to the ssd drive.

The version of alsa in the newer kernels support the aspire one better... so I read.

Boot speed of a full install of Ubuntu is about 55 seconds
linux4one custom Ubuntu about 50 seconds
plain puppy is about 1:02
my version about 1:10
Linpus that comes with it 20 seconds
Faster from a usb stick than from the internal drive.

It would be nice to see boot times on the Aspire of 30 or 40 seconds although this may not be realistic with a generic kernel.

Thanks for the help and for the base you have given me.

I downloaded it, but i can not mount it:

mount: wrong fs type, bad option, bad superblock on /dev/loop0,

Compressed with SquashFS-LZMA-3.3, official puppy releases won't mount it. You must use my puplet, or any other with SquashFS-LZMA-3.3.

More reasons to recompile:
    Some people use Ndiswrapper to load WinXP drivers, but with this kernel...
    Code:
    *** WARNING: This kernel uses 4K stack size option
    (CONFIG_4KSTACKS); many Windows drivers will not work
    with this option enabled. Disable CONFIG_4KSTACKS
    in kernel's .config file, recompile and install kernel

    I can't compile the latest drm-intel modules (i830 compiled, loaded and untested. i915 refuses to compile) for 2.6.27.5. I ended with the whole 2.6.29rc2 source tree when downloading drm-intel Crying or Very sad
Not so bad, because I don't need/have an AMD/ATI gpu, intel gpu, nor wireless devices Laughing I designed this iso just for me and my needs, but who cares it was fun!

My vote goes to compile another kernel and pack it in puppy-unleashed*s format. Newer kernel release? of course, as long as it can use squashfs-lzma and aufs by default.

Please read this:
    http://www.squashfs-lzma.org/ wrote:
    SquashFS version 4.0 is included in Linux Kernel 2.6.29. LZMA support is not there, but since squashfs made its way to the kernel, LZMA compression algorithm will follow it sooner or later. What does it mean for this project (squashfs-lzma.org)? There is no longer any interest in developing separate patches against squashfs 4.0. If you need it, you'll most likely find it in official Kernel 2.6.30 or so. So don't worry, be happy Smile

PostPosted: Fri 13 Feb 2009, 14:35    Post subject: kernel 2.6.29rc4
Subject description: 20 to 30 mins. to compile, intall and boot
 

I'm using the latest kernel (2.6.29rc4), with requested modifications to .config file (MU, iscraig, ndiswrapper) I have no problems with this new kernel even after installing the latest nVidia's beta driver. Except for SquashFS-4.0, it is not compatible with older versions!! I was unable to use Puppy2/3/4 sfs files compressed with or without lzma.


Now I'll test this:
Ubuntu linux-source-2.6.28 (2.6.28-8.21)
http://packages.ubuntu.com/jaunty/linux-source-2.6.28

very good!
Ok, incompatibility with other sfs is an argument against it - so if 2.6.28 does not have that issue, we should prefer that maybe.

I think the main advantage of 29 is the new implementation of some xorg related features.
But it then will certainly take a while, until a stable xorg supporting this correctly, will follow.
And that again then must be supported by Ati/Nvidia.
So this might not be usable until mai or so.

Thanks for keeping us up to date with your current progress, I really appreciate this.
So I will try to look at some remaining issues with newyearspup instead of running own kernel-experiments this weekend.

Mark

on the other hand, sfs are often pretty specific.
Also Puppy 4.2 will not support more that 3 sfs I think.
So for me it would be ok, to "convert" such sfs to the unnamed puplet on request, and host them.

So if 29rc runs stable, why not...
Curious about what you will prefer Smile

2.6.29

NO) it's not my intention to create a new distro.

NO) I prefer SquashFS-LZMA because I have puppy installed to a USB flash device and use it all the time, filesize is important to me 'cause I just have 1GB for data (.sfs and .2fs)

NO) I don't want to convert all my SFS to the new version. (specially if I need to share some sfs to puppy3)

YES) my sqlzma compressed SFS are not compatible with official puppy releases, the same will happen with squashfs-4

YES) software compiled in this puplet are not compatible with puppy 4/3/2/1

YES) since I made this puplet just for me (initially) I don't care if other users can't use their old SFS files Twisted Evil

YES) what if I remove SquashFS-4 then add SquashFS-LZMA-3.4?

not to forget, we still could stay with 2.6.27.
For me it works fine.

removed this message, a it was related to a ntfs error in newyearspup only.
Issue seems to be solved:
