Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@snack: In the mean time I also asked about the issue on ck's blog and got a clear response from him. Apparently PSI is a debugging feature and according to ck there's not much point in enabling it. You can disable PSI by adding 'psi=0' kernel parameter and get rid of the message at boot.

@graysky: Maybe you could change the default here by setting CONFIG_PSI_DEFAULT_DISABLED, so linux-ck users won't have to set any specific kernel parameter to fix this. Just a suggestion, I do realize this would be extra work for you.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Let me see where that got enabled and fix.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

The CONFIG_PSI=y option is set in the default Arch config that I mirror for linux-ck.  It can be disabled easily enough... I am wondering what in the CK patchset is triggering it and is it a false positive?  4.20.0-2-ck1 has this setting disabled, but it seems cosmetic unless the warning has a functional implication.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@graysky: IMHO it would be easier to leave CONFIG_PSY=y as is and change # CONFIG_PSI_DEFAULT_DISABLED is not set instead. Setting that as CONFIG_PSI_DEFAULT_DISABLED=y will save users who want to disable the PSI feature from making any changes. Only users who want to keep the PSI feature would have to use kernel parameter 'psi=1' to override.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@glitsj16 - Good idea.  See 4.20.0-3-ck1

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Hi,

i have a problem using linux-ck (from this repo) on my encrypted system.

If i boot linux-ck i get to the point where i have to put my password for my root device, what i do.
After that i got told that there is no key available.

I already tried mkinitcpio -p linux-ck to make sure everything is in the initramfs.

I use the exact same syslinux configuration for both kernels, stock arch kernel works, linux-ck doesn't.

As i get no error message i have a hard time to debug this.

Edit: i switched to sd-encrypt for testing purposes and there i could see that typing my password is the problem.
Letters sometimes get typed twice, so the 'password' looks like this: paassswordd
But i have no fix yet...

syslinux.cfg:

LABEL arch-ck
    MENU LABEL Arch Linux CK
    LINUX ../vmlinuz-linux-ck-nehalem
    APPEND cryptdevice=UUID=7547848498894994:root root=/dev/mapper/root rw nvidia-drm.modeset=1
    INITRD ../intel-ucode.img,../initramfs-linux-ck-nehalem.img

LABEL arch
    MENU LABEL Arch Linux
    LINUX ../vmlinuz-linux
    APPEND cryptdevice=UUID=7547848498894994:root root=/dev/mapper/root rw nvidia-drm.modeset=1
    INITRD ../intel-ucode.img,../initramfs-linux.img

mkinitcpio.conf (snippet):

MODULES="ext4 nvidia nvidia_modeset nvidia_uvm nvidia_drm"
HOOKS=(base udev autodetect keyboard keymap consolefont modconf block encrypt lvm2 filesystems fsck)

/etc/crypttab (snippet):

lvm             UUID=5750v74633457968       /etc/my.key luks

Any hints what i could try?

Thanks in advance and cheers

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@bigfreak - It would appear the ck1 patchset does this, see here for a diff of the Arch config before and after simply patching with CK1: https://github.com/graysky2/4.20.1_temp … 6faa187273

Recommend you post to CK's blog referencing that diff and your problem.  Might be that he did not mean to do that if I am correct.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Yes, but someone can still ask CK if it is intentional and needed particularly if it affects functionality of docker.

done and the response from ck

No, docker and containers that use CPU scheduler cgroups in general do not work at all with MuQSS. There is no 'containment' as such, and the cgroups are only there to allow systems to run that mandate their existence. from https://ck-hack.blogspot.com/2018/12/li … 7335602087

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Yeah, I can confirm that, unfortunately. I think it'll be wise to drop a line in the wiki (linux-ck and docker, perhaps?) in case someone gets stuck in docker wondering what may have happened ... It's a pity, though hmm

I will, since I had to change the output of pacman -V to match a prior version so I can pass on the wiki registration riddle big_smile

Done. Added troubleshooting entries for Linux-ck and docker. Thanks!
