Custom kernel (linuxNN-vd)

General system Kernel & Hardware
#1

I’m in the process of migrating my custom kernel to Arch/EOS, currently, this is 5.8-rc.
As Manjaro uses a custom mkinitcpio, some changes to the PKGBUILD were necessary.

However, I left Manjaro’s extramodules handling in place.

From what I can tell, EOS doesn’t use extramodules, and relies on dkms for out-of-tree modules, is that correct?

If you want to have a look at it, and maybe even compile and install it, here you go:

(Note: it still says “for Manjaro”, haven’t updated that part yet)
(Note 2: virtualbox host modules do not work yet with 5.8)

Any sort of feedback is welcome!

Can linux 58 be installed?

Apart from any modules included in the Arch repos, yes.

I really think you should reconsider the name for your kernel. :wink:

What are those btw, can you expand a little? :slight_smile:

Just tested this with acpi_call module.

Both dkms and extramodule work correctly.
However dkms does not work if the kernel is compiled with Clang, but this is a known problem: CC=clang has to be passed to make in dkms.conf.

So it seems that both ways are possible, which is good news :slight_smile:

@jonathon: correct.

Why? :slight_smile:

Uhh…because in many English speaking countries, vd has this meaning. :thinking:

That is probably the last thing that comes to my mind when I think of ‘vd’…
Actually never heard of that term, despite having watched all of House MD :slight_smile:

(Hint: it stands for ‘Victor Development’, quite cheesy isn’t it?)

:rofl:

Also it can potentially be spread and adopted as fast as vd, which should be good! :laughing:

P.S. @dalto Haven’t seen this one coming too

vd is rather an old term, the new term is STD So don’t use that one either.

This is starting to sound like a class I took in high school. :hear_no_evil:
Just for historic reference, I graduated from high school in 1968. Yah, hippies, Vietnam War, Timothy Leary, and a lot of other weird stuff.

What does the Z stand for in ZSTD? :exploding_head:

Now that’s funny!

Seriously, knowing it’s facebook standard…you just can’t make that up! :laughing:

I think i need to check up on doctor, just as you guys, i have about 1000 zstd packages on my system now, not looking good :rofl:

Of course they unpack and transmit on your system very fast, but i’m not sure i’m fan of Zuckerberg’s std :rofl:

Given that this kernel supports ZSTD kernel and initram compression, I’d be very careful… :sweat_smile:

Compiled and packaged 5.8.0-3 on my GL702ZC, when I install I hit:

Used the generic x86_64.config and skipped nconfig.

I have this in my mkinitcpio.conf:

MODULES=(xxhash crc32c amdgpu lz4 lz4_compress)
...
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
COMPRESSION_OPTIONS=(-12 --favor-decSpeed)
#19

see this

may be missing patches zstd and also update mkinitcpio.conf
if you want use zstd

#20 
$ pacman -Qs zstd
local/lib32-zstd 1.4.5-1
    Zstandard - Fast real-time compression algorithm (32-bit)
