@damentz Not yet, I'll be looking for a way to find the source of the problem. Now I can only share a part of the code on linux-xen and linux-lqx in common places. There are differences there.
I don't know if it's related yet, but maybe it will lead to some thoughts.
linux-zen https://pastebin.com/XNPH6WRE
linux-lqx https://pastebin.com/kvAX7Jzu
UPD
I checked on an already compiled kernel from liquorix.net (to exclude my configuration changes) and the warning persists
@glorious-yellow: Liquorix uses PDS from Project-C: https://gitlab.com/alfredchen/linux-prjc. However, the maintainer appears to be absent, so I've been maintaining necessary changes and optimizations in Zen Kernel here: https://github.com/zen-kernel/zen-kernel/commits/6.6/prjc
@vlad1.96: That's odd, do you have any kernel output that explains why it fails? The BPF configuration compared with linux-zen is for the most part identical aside from support for kprobe error injection. All the options for BPF as an LSM module and HID_BPF are enabled.
Can you tell me which patches or modified configurations of linux-lqx (in relation to linux-zen) affect bpf-lsm and hid_bpf?
For about half a year now(i've never seen this before), one warning and one error:
archlinux kernel: hid_bpf: error while preloading HID BPF dispatcher: -22
arch systemd[1]: bpf-lsm: Failed to load BPF object: No such process
There is no such thing on linux and linux-zen.
PS Thank you for your hard work
What scheduler is used in this patchset? It works very differently than the current upstream EEVDF.
It looks like that patch may have other side effects, and it was also shot down later in the thread: https://lists.freedesktop.org/archives/amd-gfx/2023-October/100334.html
I'd suggest monitoring the two open issues that are related and let me know if they come up with a complete solution:
Can this patch be added? https://lists.freedesktop.org/archives/amd-gfx/2023-October/100298.html
Currently running clinfo or using DaVinci Resolve would lead to kernel bug; this patch would work around that for now.
@damentz, Thanks, everything is working now! I signed the kernel with my keys and enroll them along with the microsoft keys. Kernel modules sign is something new to me and I don't know anything about it
@vlad1.96, interesting, I thought it's impossible to run secure boot without a stock kernel signed by Microsoft keys. This is new information to me.
Regardless, given you're able to boot in secure boot mode but not load DKMS modules, the reason why the modules can't be loaded is I recently configured Liquorix to use security settings similar to linux-zen and Debian stock.
A new version is on the way (and immediately available through AUR), that reverts those recent changes. Let me know if that helps.
I have something strange with signing modules for secure boot with this core in the last month. Nvidia drivers are not loading with the error: Failed to insert module 'nvidia_uvm': Key was rejected by service. I tried 2 packages: nvidia-dkms and nvidia-beta-dkms, I tried to compile the kernel from here and from the repository. The linux and linux-lts kernels installed nearby working (they also generate kernel modules via DKMS), but linux-lqx does not. Has anything changed in the kernel that affects the signing of kernel modules? I'm not sure if the kernel is to blame, but for some reason the problem is with it. I tried to completely reinstall the system and reinstall the kernel and it doesn't help
linux-zen is a conservative enthusiast kernel that works well in most situations, linux-ck is CK patches on mainline (obsolete since Con doesn't maintain it anymore), linux-lqx is a variation of zen with a focus on low latency at cost of throughput.
