amd_pstate not available. #189

This commit explains it: 07b176e |
Thanks @hwsmm, it's common for popular distributions to override the power profile of the kernel to serve laptops better. Unfortunately, that improvement in efficiency leads to a large number of common workloads performing very badly. Specifically, single threaded tasks that don't quite saturate the single CPU they run on. In Zen Kernel, acpi-cpufreq has been tuned to cause the CPU to enter boost mode far sooner than stock (about 60% CPU per core). And on Liquorix, the performance governor is selected by default, but ondemand is also available if you want to tune your system for lower power. And you can always add |
I tried appending Also let's say I don't go with the Thank you @damentz @hwsmm for entertaining my question. Best regards, |
That's interesting, I tested the disable + active mode on a local system and it worked. Maybe your system is not compatible with amd_pstate? I can retest this behavior once I have access to my AMD system in the next day or two. |
In my case adding The problem for me is that utilities like cpupower_gui don't work without amd_pstate. On the other hand this seems to be on the 6.12 kernel because on 6.13 it doesn't seem to be necessary, I'm anxiously waiting for |
I added |
I recommend you to wait for version 6.13, maybe it will solve itself, I don't think it will take more than a few days. |
Hi @Insurgent65. Okay, I will just wait for the new update. More power to the devs and thank you for this wonderful kernel. Best regards, |
The only wait is on an update from Project-C. The developer behind is working on fixing a regression in scheduling plus the sync-up with 6.13. It may be another week or two before Liquorix is on 6.13. If the dev falls behind too much, I'll take a shot at doing the sync-up myself. EDIT: Here is the regression I reported if yall are interested: https://gitlab.com/alfredchen/linux-prjc/-/issues/104 |
you are going to have to make a decision, the deadlines for the fix expired a long time ago, I don't know the extent of the problem either, can we live with this bug? |
This exact same issue happens with In my machine, if I set If I set Please note that if I install the kernel from the official Debian repo, the My installed current kernel version is |
If it helps anyone, I have chosen to stay with the 6.11 version that you can download from here: The problem is that it has no maintenance, but it is only while version 6.13 arrives. |
Setting |
Liquorix version 6.13 runs smoothly, with a noticeable performance increase. |
Hi,
I just noticed that on the kernel config you prefer to disable
amd_pstate
and useacpi-cpufreq
.What are the benefits in using
acpi-cpufreq
instead ofamd_pstate
.Is there an easy way for this to be enabled or do I have to recompile the kernel and remove this line
CONFIG_CMDLINE="audit=0 intel_pstate=disable amd_pstate=disable"
Thanks,
Jan
