Not build with kernel 5.8.3 have bug

[micron10]

Hi Hamad I try to build with latest kernel 5.8.3 but have a small problem please see log:

Hi Micron,

I haven't yet made the patch working on 5.8.3. I believe they have done some changes on the scheduler in 5.8.3. You could try it on version 5.8 https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.8.tar.xz Please let me know if you have any issues with 5.8.

It seems to me that 5.7.10 kernel version has a better performance than 5.8 (with and without the cachy patch), you might find 5.7.10 faster than 5.8.

I will try to make a patch for 5.8.3 Thank you

[micron10]

i will try 5.7 kernel if have news with patch update for 5.8 kernel please write my

compiles and works great on 5.8.3.... probably didnt disable FAIR_GROUP_SCHED and NUMA in config

[hamadmarri]

Hi thor2002ro,

I already added the disable FAIR_GROUP_SCHED and NUMA changes in patch 5.8. It should be disabled automatically when applying the patch.

Thank you

Hi @micron10,

Could you please attach the output of patch command. And also the .config file. Did you downloaded the full cachy tree kernel or you downloaded the kernel from kernel.org and patched it?

[micron10]

Hi sorry for the late reply when disable Cgroup and Numa build is fine without any problem. But i run on server not in desktop pc for game. On server for routing this sched is not ok. Server is overload and i remove patch for now.

Doesn't work with 5.8 from the 5.8 branch of this repo either:

Hi Heimen,

Doesn't work with 5.8 from the 5.8 branch of this repo either:

For 5.8 branch you need to disable FAIR_GROUP and NUMA manually

[Vistaus]

Hello Hamad,

I did disable those.

[hamadmarri]

Could you please confirm with cat .config | grep FAIR Sometimes you need to touch .config file to let the make knows it's been changed (when renaming .config)

[Vistaus]

Hmm, seems like it keeps re-enabling FAIR_GROUP_SCHED automatically in .config. Even touching it doesn't seem to do anything :/

[hamadmarri]

Using make menuconfig?

[Vistaus]

Using make menuconfig?

Yes.

[hamadmarri]

Could you please try this patched tree https://github.com/hamadmarri/linux/releases/tag/cachy-5.9-r1

[Vistaus]

Not working either, but this time because make menuconfig instantly fails:

bump :)

In the meantime, I tried an easier way and installed the experimental XanMod Cachy kernel, but it did not boot past Plymouth, so unfortunately that's a no-go.

[hamadmarri]

Hi Heimen,

I think you have permissions problem. Not sure why you have Permission denied

I am going to double check if the edited files have different permissions in the repo

[Vistaus]

Thanks for looking into it! :)

[hamadmarri]

Hi Heimen,

From your build errors:

sh: 1: ./scripts/gcc-version.sh: Permission denied
sh: 1: ./scripts/ld-version.sh: Permission denied
sh: 1: ./scripts/clang-version.sh: Permission denied

I suspect that the problem is related to gcc or clang installation Please try to check the current gcc in your machine, it looks like make is not able to reach gcc

[Vistaus]

I have no problem compiling other software.

[Vistaus]

I now got XanMod-5.9.0-rc3 with Cachy to boot so this is no longer an issue. Thanks for all of your help, though! :)

[hamadmarri]

Hi Heimen,

Good to hear it is working, I am compiling XanMod-5.9.0-rc3 right now :+1: :+1:
