Porteus Kernel Builder

[fulalas]

@Blaze, this kernel 6.7.2 module you built increased memory consumption in a VM from 720 MB to 945 MB. I'm intrigued to know what's wrong. I hope it's not a new trend in the kernel

hi fulalas, porteux 0.9 with firefox on now it have 8.75giga of memory out,but i have also 700 modules activated,ok the kernel is:
Linux porteux 6.6.14-porteux #1 SMP PREEMPT_DYNAMIC Sat Jan 27 00:48:07 CET 2024 x86_64 AMD Ryzen 5 3500X 6-Core Processor AuthenticAMD GNU/Linux,

@Blaze, this kernel 6.7.2 module you built increased memory consumption

I can confirm:
452 MiB (kernel 6.5.5)
614 MiB (kernel 6.7.2)
RAM - used, VirtualBox, KDE x64, Always Fresh, without browser

[fulalas]

@AcnapyxoB, thanks for confirming.

It seems it's not just us or anything related to AUFS:

expand & AUFS patch

I use expand & AUFS patch and options with aufs in config are missing.

which version have you used for the 6.7 kernel branch

stable branch.

Code: Select all

# Porteus 5.01 x86_64 + Firefox and one open tab
# free -h
               total        used        free      shared  buff/cache   available
Mem:            15Gi       1.9Gi        12Gi        29Mi       1.4Gi        13Gi
Swap:             0B          0B          0B

Any of basic patches (kbuild.patch, base.patch, mmap.patch) of AUFS does not patch succesful,
No AUFS patch are applied (OverlayFS).

For 6.7.2 AUFS patch version "6.x-rcN-20231106" has patching mmap.patch error (FAILED).
(cat aufs6-mmap.patch | patch -p1)


Please refer to /usr/local/share/mkKernel/bin/aufsBase.sh

Thanks.

[Blaze]

neko, now is clear.
I have one question. If I want to build OverlayFS do I mast to choose "expand only" option right?
And I wanted to hear your opinion about OverlayFS (pluses and minuses)

Thanks

Yes, you do right.

[OverlayFS]
Good point(pluses)
This is a standard kernel feature.
Released with kernel updates.

Bad points(minuses)
If the overlapping space created by mounting XZM modules is your own OS driving space
XZM modules cannot be added or deleted later.


Thanks.

XZM modules cannot be added or deleted later.

In that case I treat them as some kind of tar/zip:

Code: Select all

# Show progress
dots () {
   TRACING="$(echo $- | grep x)" ; set +x

   while [ -d /proc/$1 ]; do
      echo -n '.' ; usleep 300000
   done

   [ -n "$TRACING" ] && set -x
}

.....

# The files
while [ -n "$1" ]; do
   FB="$(basename "$1")"

   echo -n ">>> $1"
   [ ! -r "$1" ] && { echo " does not exist" ; shift ; continue ;}

   F="$1"

   FF="$(mktemp -d "/run/sqfm.$FB.XXXXXXXXXX")"
   echo "$F" > "$FF/_TAG_"
   mount -t squashfs -nro loop "$F" "$FF"

   echo -n " ."
   rsync -aS "$FF/" / &     # did not find a faster method
   dots $!
   echo

   umount "$FF"   

   shift
done

From kernel version 6.6.12 onwards I'm not able to boot in my AMD Ryzen 7 machine.
Everything seems to indicate that it's related to the graphics card:
AMD Renoir Radeon RX Vega 6 (amdgpu driver)

However, same kernels are working fine if using Intel or Nvidia graphics cards.
Wich config should I change? It is posible to try that config at boot in the append line?

@neko
I hope you are well.

Thanks so much

hi M.Eerie have you seen this:Hm, it seems that `pci=noats` kernel parameter fixed the problem, i have a AMD Ryzen 5 3500X but with no graphic on board.

[M. Eerie]

Thanks, beny.
I've tried pci=noats but no luck.

I remembered that I had recently disabled iommu from the BIOS so that I wouldn't have to continually do it with amd_iommu=force_enable iommu=pt etc., but having reverted to the previous situation, it hasn't worked either. The screen freezes when I press "Enter" and the system won't boot.

I thnk switching to AMD Radeon has been a bad decision on my part. It is a rather problematic system that often freezes and I end up powering-off quite often losing all the work.

That's disturbing. Does anyone have a better experience? I was about to buy a mini PC, and the best candidate seemed to be Beelink's Ser5 AMD Ryzen 5 5560U with Radeon Graphics built-in. Should I avoid that and buy a (more expensive) Intel equivalent, in order to enjoy a better Linux kernel compatibility?

[ncmprhnsbl]

Does anyone have a better experience?

i haven't had any problems with the AMD Ryzen 5 7535U with it's builtin radeon 680M in my lenovo yoga 7.. which is newer than these others that seem to be having some trouble..
i was under the impression that the AMD drivers have had pretty good support.. but maybe not so much right across the board, lately..

[fulalas]

From kernel version 6.6.12 onwards I'm not able to boot in my AMD Ryzen 7 machine.

I have the same issue here. Ryzen 7840HS + AMD 780M integrated GPU.

On PorteuX it works though
