Running fine on my VM running on top of KVM

5.8 seems to be running really well, both the normal linux and linux-zen variants (thinkpad x1 carbon)

Everything here appears to be running okay (linux 5.8.1.arch1-1 plus linux-lts 5.4.58-1; running the first). Having read some of the problems some people had had, I was a bit worried.

But I needn’t have been.

Upgraded with the 5.81 zen with Nvidia 450 and all good, and regular 5.8.1 on my laptop/Intel gpu all good. I wasn’t use to being thrown into a new kernel automatically, unlike Manjaro’s way. Pretty cool…and a little :poop: in my pants.

All looks normal, linux zen, linux lts, and mainline. Updated a few minutes ago.

Looks like there is more lurking in kernel 5.8.1, first time at my desk today with two external monitors and right away I had a couple of Bumblebee crashes and another Virtualbox crash this morning. About time for 5.8.2 :slight_smile:

5.8.2 brings in a lot of fixes (over 400).
For 5.8.3, already about 100 fixes in the queue… :slight_smile:

Nice! A lot of Bluetooth too. From glancing over it the BT issues 5.8 introduced could be fixed.

Aaand 5.8.2 is out. Bluetooth connection issue seems to be fixed and it’s working as expected again. :raised_hands:

It looks like schedutil replaced powersave as scaling governor? :thinking:

On Intel or AMD?
I think schedutil has been the default for (newer) AMD since some time already, but not sure.
My Intel laptop still is on powersave but that might be some setting.

Intel IvyBridge. Conky is always running and I noticed that the frequencies were somewhat unusual for the load. This is 5.8.2:

# cpupower frequency-info 
available cpufreq governors: performance schedutil

Checking on 5.4 LTS its still performance and powersave.

Hmm on Kaby Lake I still have performance and powersave …
Maybe you need to load the module?
sudo modprobe governor_powersave
sudo modprobe cpufreq_powersave

Interesting. Currently I see a few hundred MHz more on light load but also slightly lower temperatures (it’s a desktop). I guess it’s fine. I was just irritated having that change happen on a minor release.

5.8.4-rc1 just hit and it looks a little more reasonable in size. Maybe this one will fix my touchscreen (that still works fine with 5.7)

Edit: 5.8.4-rc2 just hit, so it is no longer a little update, though still smaller than 5.8.2 and 5.8.3. 5.8.x might take a while to get sorted out.

see this

from The kernel’s command-line parameters — The Linux Kernel documentation

intel_pstate=
value are disable , passive , force , no_hwp , hwp_only ,support_acpi_ppc ,per_cpu_perf_limits

try with hwp_only ,per_cpu_perf_limits , force

check on kernel 5.8

@Stephane Thanks, I’m fine at the moment.

I’m getting powersave back with modprobe as described by @anon31687413 , but for whatever reason that currently hard throttles the CPU to the minimum frequency. :man_shrugging:
