Hello,
“amd_iommu=on iommu=pt processor.max_cstate=5 systemd.unified_cgroup_hierarchy=true scsi_mod.use_blk_mq=1”
Can You explain about parameters? I’ve found some of them so:
amd_iommu=on iommu=pt → https://community.amd.com/t5/knowledge-base/iommu-advisory-for-amd-instinct/ta-p/484601
how check current value to see any difference?
processor.max_cstate=5 →
sudo cat module/processor/parameters/max_cstate
the value is 8 so What are the CPU c-states? How to check and monitor the CPU c-state usage in Linux per CPU and core? - GoLinuxHub in my opinion this state is better.
systemd.unified_cgroup_hierarchy=true → please explain
scsi_mod.use_blk_mq=1 → I have on Y
cat /sys/module/dm_mod/parameters/use_blk_mq
│ File: /sys/module/dm_mod/parameters/use_blk_mq
1 │ Y
EDIT:
The core dumps comes after failed update of the system. I had this issue (now is fixed but don’t know that is not connected] System Crash during update - #27 by pawel with glibc and GPG and certificates.
